Abstract

An agriculturally effective active ingredient is applied to plant foliage before, after, or simultaneously with an enhancer component containing a substantially pure bacterial culture, suspension, spores, or cells of a bacteria selected from the genus Bacillus or a soil bacteria.

Description

AGRICULTURAL COMPOSITIONS CONTAINING BACTERIA FIELD OF THE INVENTION The invention relates to the treatment of plants with a composition containing an agriculturally effective active ingredient and a flattening additive containing a culture of substantially pure bacteria selected from the genus Bacillus or a soil bacterium. The added culture may be in the form of a cell, spores or suspensions. BACKGROUND OF THE INVENTION Manufacturers of chemical compounds for agriculture always seek ways to -improve the efficacy of the active ingredients used in plants. This is particularly true in cases where the applied material is a regulator of plant growth (growth-weakening or growth-promoting), herbicide or systemic agent (eg, insecticide or "fungicide") The transport mechanisms within the plant and of translocation between the various tissues of the plant are important and, in some In the case of some active ingredients, an improvement in the transport mechanism could translate into better performance at current application rates, the need for a less active ingredient. , or the ability to treat new species that were previously resistant to the active ingredient. "" "Mepicuat-chloride is an active ingredient in which" the absorption of the plant and its transport are important. of N, N-dimethylpiperidinium) is used annually as the active ingredient to weaken the growth of the vegetative cotton plant and increase retention of fruits in millions of acres of cotton. Mepicuat-chloride also has certain uses in potatoes, sweet potatoes, peanuts, grapes, corn, wheat, citrus fruits, tomatoes, and onions. The mepicuat-chloride has the effect on the cotton plants of weakening the vegetative growth, forcing the plant to redirect its energies to the production of fruits (cotton capsule). With the proper application of mepicuat-chloride in plants that begin to show excessive vegetative growth, the yield of cotton plant can be maintained or increased without damage to the plant. The effects of weakening growth are particularly desired when the crop is grown in fertile soil or after climatic conditions that favor the growth of the plant rather than the production of the fruit.
Cotton plants have a life cycle and a foreseeable growth period. Cotton plants emerge 7-10 days after the seeds are planted in a furrow. The cotton plant shows growth of a root system and the extension of the height of the plant through the growth of the stem and the branch in a pattern called vegetative accretion approximately until the 4th to 8th spadix. Thereafter, the plant produces a reproductive branch (the first fruitful), and all the posterior branches are reproductive. The cotton growers try to control the growth of the plant to ensure that the proportion of vegetative growth in relation to reproductive growth (cotton production) favors the desired range of reproductive growth. Cotton harvesters usually prefer to see about 2 inches (5 cm) between the spadices of the main stem. This ratio represents a balance between too much reproductive growth (cotton production) that can cause plant growth to be faster than the rate of vegetative growth and end before yield is maximized, and too much vegetative growth that reduces the number of mature cotton growers. The cotton plants that have directed most of the available plant energy to vegetative growth are called Ade ranges and produce cotton plants that mature later and are vulnerable to extremes of climate for longer periods of time. Cotton that shows signs of becoming Ade rows is easily visible because of the abnormal height of the plant in relation to the cotton loads and the number of spadices of the main reproductive stem. Mepicuat-chloride is used to prevent the cotton from becoming Ade rows by modifying the growth characteristics of the cotton plant. The branches of the main stem usually extend always to alternate sides. Each place on the branch is called Aespádices forming 5-7 spadices above the cotyledon leaves before the first fruitful branch with true leaves forms. The counting of spadices begins at the bottom of the plant and extends up the main stem. The elongation between spadices is the distance between the places of the branch where a new spadix is being formed approximately every three days. For measurement and comparison purposes, the number of spadices and the length between spadices above the spadix 8 are generally used to eliminate the variations of fruit spadices between plants because the fruitful branches will necessarily have formed towards the spadix 8. The count of fruitful spadices is therefore initiated , conventionally, from the first reproductive spadix, usually the number 7 or the number 8. The fruitful places in the cotton are called Acuadros = .- - Each fruitful branch will form from 1 to 6 fruitful places (Acuadros =), normally some 3, with approximately six days between the frame formations in each branch. The new frames and the beginning of the reproductive growth in the cotton plants are called Ade Adeps head due to their barely visible size. After about 5 to 10 days, the painting has grown to a size equal to the head of a match and is a period in the life cycle of the plant called Match Head Match. - The phosphorus head chart continues to grow to the size of an average adult nail before flowering (early blooms). Three days later, a cotton tree has formed under the bloom. About thirty days after the early blooming, the cotton grower is fully ripe and ready to harvest. In general, 80% of l cotton production is established within the first 3 weeks after early blooming and 95% of l production is established within 5 weeks of early blooming. Usually, mepicuat-chloride is applied to cotton plants in one of two ways. The method used until about 1986 was a unique application of 8-16 ounces per acre of a 4.2% by weight solution in early flowering. This type of unique treatments controlled the height of the plant, although it was noticed that the production of the plant was occasionally reduced, particularly if the plant was stressed during or after the application. Since 1987, the tendency has been to apply mepicuat-chloride in a series of applications, each having a lower dose than the application of the single dose. The first treatment occurs in the phosphorus head frame with a second treatment 7-14 days after it. Both treatments are done at a rate within the range of approximately 8 ounces of 4.2% by weight solution per acre with the specific application rate depending on whether the cotton plant showed signs of being stressed (no application), moderate growth (approximately 2 ounces of solution per acre), or vigorous growth (approximately 4 ounces of solution per acre). From this, two additional treatments can be applied at intervals of 7-14 days with application rates of up to about 8 ounces of mepicuat-chloride solution at 4.2% by weight depending on the rate of specific application of the amount of vegetative growth in field. Additional experimentation by individual harvesters has resulted in a variety of multiple application rates. It would be desirable if the use of mepicuat-chloride could be integrated into a treatment system that would increase the mass of the plant tissue in the roots, stems and leaves to provide higher level transfer levels while restricting vegetative growth to favor the production of fruits. The technology of herbicides for plants has a continuous desire for greater efficiency without a corresponding increase in the rate of application. Many herbicides could also use an activity improvement without an increase in the amount of herbicide applied. Farmers and herbicide manufacturers often face the need to control weeds and harmful plants without increasing levels of proven herbicide application, if the plants can be controlled at all. Some plants, such as the Florida Pusley Richardia Sabrá, Bull Grass, Bermuda Grass, Hedionda Chamomile and Primula are very resistant to the herbicides that have proven their effectiveness. It would be useful to have a means to increase the efficacy of active ingredients in agriculture, such as herbicides, without increasing the amount of active ingredient applied. SUMMARY OF THE INVENTION It is an object of the present invention to provide a composition and method of use therefrom to increase the effectiveness of active ingredients effective from the agricultural point of view.
It is a further object of the invention to provide a composition and method for its application in fruitful plants and seeds that increase the number of fruitful places in the treated plants with the goal of providing greater fruit production. It is another object of the invention to provide a composition and method for its application in which the treated plants grow in a healthier condition. In accordance with these and other objects of the invention that will become apparent from the description herein, a composition according to the invention comprises: (a) an agriculturally effective active ingredient, and (b) ) a flattener containing a culture that includes bacteria of the genus Bacillus or a soil bacterium in the form of cells, cultures or suspensions and in an amount sufficient to promote the effectiveness of the active ingredient. Preferably the flattener is free of plant growth hormones when used in combination with agents that weaken the growth of the plant, for example, mepicuat-chloride which suppresses the growth hormones of the plant in the treated plant. The compositions according to the present invention improve the efficacy of the active ingredient applied agriculturally. The same amount of active material that is conventionally applied will be more effective. Lower levels of the active ingredient can be used to achieve the same effect as the higher conventional application rate. In addition, the plants that have been treated with the compositions according to the invention are healthier with the concomitant benefit of being more resistant to diseases by other stress in addition to showing greater number of fruitful places and higher production. DETAILED DESCRIPTION The invention provides a method for treating plants with a composition containing an agriculturally effective active ingredient and a promoter containing a culture of a bacterium selected from the genus Bacillus or a soil bacterium in an amount sufficient to favor the effectiveness of an active active ingredient from the agricultural point of view applied simultaneously, before or after the application of the flattener. The greater effectiveness attributable to the flattering component containing bacteria can be exploited to reduce the amount of the active ingredient applied from an agricultural point of view or, when the ingredient is applied at the same rate, the bacillus increases the effectiveness of the effective applied active ingredient from the agricultural point of view. Said greater effectiveness useful for controlling weeds that are otherwise difficult to control with normal herbicides.
THE FAVORIER OUE CONTAINS BACTERIA The flattening component contains spores, cultures and suspensions of a bacterium of the genus Bacillus or a bacterium of the soil. Preferably, the bacteria for the flattening component is in the form of spores as a result of a suitable adjustment in temperature, pH, salinity, etc. Bacteria suitable for use in the present invention include those bacteria that exhibit an ability to increase the effectiveness of an agriculturally effective active ingredient through any mechanism. Methods for reviewing bacterial strains in terms of bioactivity and, therefore, their ability to improve the effectiveness of a plant growth regulator, a herbicide, a systemic fungicide or a systemic insecticide will be apparent to someone who has a normal ability in the art in view of the presentation and the examples specified herein. For example, a candidate bacterial strain, eg, Bacillus cereus, can be grown and maintained under normal laboratory conditions. (See, for example, Sambrook et al. ^ Moléc la "! - Cloning: A Laboratory Manuals Cold Spring Harbor Laboratory Press (1989).) Specific plants can be chosen for their susceptibility or resistance to a particular agriculturally effective compound., for example, a herbicide or a plant growth regulator. For example, and as specified in the example section included herein, cotton can be used to evaluate the bioactivity of a bacterial strain in combination with a plant growth regulator that is reflected in the number of fruitful sites or number of cotton producers produced and compared to treat similar plants that only have the plant growth regulator or bacteria. Alternatively, plants susceptible to certain fungal diseases, for example late tomato blight, common potato scab, black wheat rust, corn char or leaf rust from several plant species, can be grown under controlled conditions and treat either __with a suitable fungicide, a fungicide with a candidate bacterial species, or the bacterial species alone, either before, simultaneously, or after the controlled inoculation of the plants with the causative organism of the disease, to evaluate the capacity of the bacterial species to improve the activity of the fungicide. These types of experiments can be carried out in the field, in semicontrolled conditions, such as a greenhouse, or under relatively controlled conditions, for example, in a growth chamber. These experiments involve the routine review of organisms in terms of their favorable effect with compounds or compositions on known plant species, and the parameters used to evaluate the effects are known, in the same way, and are measured routinely. These similar types of revisions can be used with bacterial strains described herein to provide a favorable effect to a particular agriculturally effective active ingredient, for example, the Bacillus cereus strain deposited in the American Type Culture Collection with the ATCC No. 55675 provides an adjuvant effect to metiquat chloride plant growth regulator and atricin herbicide, to monitor bacterial species for potential benefit along with other agriculturally active active ingredients, for example systemic insecticides and systemic fungicides. Particularly preferred are cultures, spores and suspensions of soil bacteria that are between the roots of blooming growths of the plant type in the local soil. Foliar application of the local soil bacterium at an application rate in the range of approximately 0.1 X 1010 CFU / acres to approximately 10 X 1010 CFU / acres favors the natural mechanisms related to plant growth and spread to a level sufficient such that the active ingredient from the agricultural point of view shows favored activity in or within the treated plant. A wide variety of bacterial species of the genus Bacillus and within the known species of soil bacteria are useful within the present invention.

For previously mixed materials, it is desirable to select active ingredients that do not degrade or otherwise be impeded by prolonged storage under the conditions used to maintain the flattening component containing bacteria in the form of a spore. The general term Aagente plant growth regulator encompasses several active ingredients that affect the plant in different ways. Generally speaking, regulators of plant growth include agents that weaken the growth of the plant, agents that favor plant growth and herbicides. Among the plant growth promoting agents suitable for the present invention are plant growth hormones, for example, at least one of the 84 gibberellins with GA3, GA4, GA5, GA7 and GAQ cytokinins being preferred (e.g. zeatin, kinetin, benzyladenine, dihydroketine, and isopentenyl adenine), -auxines (for example, indoleacetic acid (IAA), indolebutyric acid (IBA), and naphthaleneacetic acid (NAA)), sodium ortho-nitrophenolate; para-nitrophenolate sodium; Sodium 5-nitro-guaicolate; and polyhydroxycarboxylic acids with structures of 2, 4, 5 and 6 carbon atoms; ethephon; and a variety of fertilizers that contain nitrogen or phosphorus. Among the agents that weaken the growth of the plant suitable for use in the invention are chlormequat-chloride mepicuat-chloride, as well as maleic hydrazide and its esters. Regulators of plant growth affect and alter the metabolic processes of the plant and favor or slow down its growth. All of these agents can be used according to the application and programming rates specified by the manufacturer on the product label. Herbicides include triazines (for example, atrazine), ureas, glyphosphate, sulfosate, glyphosinate, and sethoxydim. Among the appropriate systemic agents that will benefit from the absorption, transport and assimilation of the improved process of the plant stand out the systemic pesticides and fungicides. The systemic agents for plants that benefit from the present invention include, among others, the insecticides Inter alia, acephate, carbofuran, dimethoate, phorate and terbufos. Systemic fungicides that will benefit from the mixtures of the invention include tridemorph, metalaxyl, iprodione, fosetyl-aluminum, thiophanate, benomyl, triadimefon, carboxin, oxycarboxin, carbendazim, thiabendazole, thiophanate, etirimol, bupirimate and dimethirimol. Plants that can be treated with the present invention include virtually any plant grown in the soil and that is affected by an agriculturally effective active ingredient. Among the exemplary plants stand out harvests of production grains (for example, corn, wheat and soybeans), sorghum, desired and unwanted pastures, weeds, grasses, etc. The invention is suitable for increasing the production of fruits in plants that produce fruitful places from which the fruit will grow. Said plants preferably include any of the raw agricultural products and especially cotton, soybeans, peanuts, grapes, apples, citrus fruits (for example, sweet lime, sour lemon, orange, grapefruit), blackberries (for example, strawberries, blackberries, raspberries), tubers, (for example, potatoes, sweet potatoes), corn, cereal grains (for example, wheat, rice, barley), tomatoes, onions, cucurbits (for example, watermelon, cucumbers and melons). METHOD OF APPLICATION The compositions of the present invention can acquire the physical form of a liquid, emulsion, suspension, solid granule, aggregate or composite granule (for example, the solids of the active ingredient are transported in an inert carrier particle). The application of each physical form to the foliage of the plant will usually proceed with conventional techniques. Strains of gram-positive bacteria can be used in the flattening component in the form of cells, spores, cultures or suspensions thereof. In a liquid or dispersible solid form, the flattener is added to a spray tank or other form of liquid distribution tank in the form of a stable, aqueous concentrated solution showing an equivalent spore concentration within the range of approximately 300,000 units of colony formation per millimeter (CFU / ml) to about 1.5 million CFU / ml, preferably about 1 million to about 1.2 million CFU / ml to make a composition that is applied to the foliage of the plant at a rate within the range from about 0.1 X 1010 CFU / acre to about 100 X 1010 CFU / acre, preferably at a rate within a range of about 0.1 X 1010 CFU / acre to about 10 X 1010 CFU / acre, and more preferably within the range of approximately 0.5 X 1010 CFU / acre (0.5 f.oz./acre of concentrate) to approximately 8 X 1010 CFU / acre (2 f.oz./acre of concentrate) Optionally, and in a form of preferred embodiment, the spray tank will also include the component of the active ingredient effective from the agricultural point of view for the simultaneous application of both components. The solid forms of the components can be mixed dry or formed into aggregates before the emission. One or more conventional adjuvants can be used to enhance dispersion, decomposition, adhesion to foliage, etc. the specific application rate may vary somewhat depending on the method in which the solution will be applied to the surfaces of the plant. For example, aerial spraying will employ a different dilution rate and an application amount also different than spraying with a retractable tube, manual sprays, or the emission of granules. Conventional equipment can be used for the application. If desired, the flattering component can be mixed with other treatments and applied simultaneously or applied in a discrete treatment step. Foliar application is the preferred method to increase the number of fruitful places in fruitful plants. The concentrate can also be used to formulate a packaged mixture ready for use. Thus prepared, the flattener is diluted in an amount in the package container that is in the range of about 150,000 CFU / ml to about 600,000 CFU / ml and under the appropriate conditions to ensure that the bacterial components remain in a spore form but they become vegetative after the application. - For many bacteria, the use of a pH of less than 7 (that is, acid) will keep the bacteria in the form of a spore.
If necessary, any acidifying agent or buffer (preferably food grade or those classified as generally considered as safe by the United States Environmental Protection Agency) may be used to maintain an adequate acid pH during storage. such conditions, the spores remain stable and show good storage stability.When diluted for use and subsequent application, the pH of the solution will increase to more than 7, causing the bacteria found in the flattener to "become in living and vegetative colonies. The bacteria will therefore reproduce on the surface of the treated plant and facilitate the translocation of the agriculturally effective active ingredient. The flattering component containing bacteria can be applied in the form of a discrete treatment or simultaneously with several other active ingredients that are effective from an agricultural point of view. Among the active ingredients that are effective from the agricultural point of view, there are agents that favor the growth of the plant, agents that weaken the growth of the plant, herbicides, insecticides and systemic fungicides. Preferably, the composition is a combination of either an agent that weakens the growth of the plant or a herbicide and a promoter that contains a substantially pure strain of B. subtilis, B. cereus, or ATCC 55675 (BP01) applied at a rate of at least 0.1 X 1010 CFU / acre. In a preferred embodiment, a gibberellin-free flattener containing the bacillus is applied to the foliage of cotton plants at the same time that the plants are treated with mepicuat-chloride. An aqueous tank mixture containing the flattener containing bacteria (preferably ATCC 55675) and mepicuat-chloride is a convenient method for simultaneously applying the components. If pre-mixed, the mepicuat-chloride and the flattener containing bacteria can be easily stored at a pH within the range of about 4-6.5, more preferably within the range of about 5-6.5. It should be noted that the formulations according to the present invention desirably do not include combinations of materials that attempt to act in a contradictory way in the metabolism of the plant. For example, mepicuat-chloride is commonly used in cotton foliage to suppress plant growth hormones and weaken the vegetative growth of the plant. A formulation would preferably be prepared in such a way as not to include plant growth hormones because the effects of mepicuat-chloride and growth hormones would require things that contradict the metabolism of the plant, reduce the efficacy of mepicuat-chloride and lead to results inconstant With the present invention, however, the combination of mepicuat-chloride and ATCC 55675 consistently produces treated plants which have higher production, healthier growth and greater resistance to diseases. Although we do not wish to be bound by any particular theory of operation and with respect to the combined use of the flattener containing bacteria and the mepicuat-chloride in the cotton, the bacteria seem to affect the growth mechanism of the plant to increase the retention of cotton in the places fruitful 1 and 2 and increase the number of cotton growers in general by producing fruitful retention sites in normally vegetative branches. For the present invention, mepicuat-chloride is used at application rates and during the conventional growth stages of the cotton plant. Conventionally applied mepicuat-chloride rates are up to approximately 60 g / acre (25 g / acre) or approximately 1-16 ounces per acre, with individual application rates falling within the range of approximately 2.5 g / acre (1.0 g / hectare). ) for a 2 oz / acre application of 4.2% by weight solution at 10 / acre (4.1 g / hectare) for an 8 oz / acre application of the same 4.2% by weight solution. If mepicuat-chloride of greater or lesser purity or activity is used, the specific application rate must be adjusted according to the change in the conventional activity of mepicuat-chloride. EXAMPLES Example 1 An aqueous mixture of mepicuat-chloride of 4.2% by weight and 560,000 CFU / ml (laboratory sample BP01, ATCC 55675) was prepared in a volumetric ratio of 1: 1. This solution was applied by conventional sprayer in four applications to the foliage of growing cotton plants in the test areas of field A (10 of 50 acres in Mississippi) and field B (8 of 60 acres in Tennessee). Field A was treated with a dose at a rate of 4 fluid ounces per acre followed by five weeks of treatment at a rate of 8 fluid ounces per acre. Field B received a different treatment regimen. The first three applications in field B were at a rate of 4 fluid ounces per acre. (The first and second were separated by 24 days, the second and third by 6). The final application in field B was a rate of 8 fluid ounces per acre 11 days later. In all cases, the control fields were treated with the same rate but only with mepicuat-chloride. After the treatment, sampling was carried out in fields A and B by hand of the representative rows. All the known biases were placed in favor of the control treatment with only mepicuat-chloride. In fields A and B, the initial and final heights of the treated cotton plants were measured. The total heights of the plants of the control fields were comparable to what was treated according to the invention. See Table 1. Table 1 During the growing season, the differences between the control plants and those treated were easily observable. When the young plants contained only squares in the first month of fruiting, an unusually large number and an unusually large number of additional fruit branches were observed in cases where the main fruit branch emerged from the main stem. Many were as large or almost as large as the main fruiting branch and contained fruit before the first flowering. Additional fruit was also observed at the intersection of the fruitful branches and the main stem. As the flowering extended upward in the plant and only cotton plants or missing sites were found under the flowering, an unexpected amount of subsequent fruiting was also observed. Double fruiting was observed in paintings, blooms, small cottons and "cotton now open" (extraordinary). Although double fruiting occurred in both the control and treated plants, the substances were higher in the treated plants. Approximately 3-4 weeks before the end of the growth period, the plants were inspected for the number of fructification sites, number of cotton plants in spadices 1 and 2, as well as the type of cotton plant. Table 2 reports on the results of that inspection.
Table 2 In field B and at the end of the trial period, 20 plants were inspected. All the plants were cut. There were no open cotton growers in the control group and only 7 in the treated group. However, the younger fruit was larger and older for the treated plants compared to the control plants. This indicates that the plants grew at a faster and more favorable rate. The treated plants had a total of 265 cottons compared to 238 cotton growers in the control group, an improvement of 11%.
The treated plants also showed an increase in the number of fruit in the vegetative branches in the proportion of 88:51, an increase of approximately 73%. The treated plants also produced an increase in another fruit, that is, the one that fructified in branch 3 and wider positions, at a ratio of 86:50 (72% increase). The estimated weight (seed cotton) of the fruit of the 20 plants was also higher in the treated plants, 1796 g. compared to 1456 g. (23% increase). The extra fruit in the plants produced the expectation that it would be a derivation of the plant system the additional plant and fruit parts. The cotton growers would open sooner, but would adversely affect production. This expectation was not met. The treated plants grew at a higher rate and in a healthier condition than the control ones. To reduce bias, all hand-ginned cotton was harvested in test fields including cotton ginned from partially open cotton. This non-fluffed ginned cotton usually comes from cotton plants that never opened properly and are in the lower part of the plant or from cotton plants that are just opening and are located in a very high part of the plant. Table 3 reports on the weight of seed cotton and the number of green cottons per 10 feet of row in the treated and control fields Table 3 The results of the test show that the mepicuat-chloride combination applied simultaneously with a flattener containing ATCC 55675 according to the invention produces higher yields of healthier cotton and plants than the use of mepicuat-chloride alone. Use 2 _ Strain BP01 (ATCC 55675) from Bacillus cereus was used in combination with a widely used herbicide, atrazine, to determine if BP01 would affect control over weeds that are recognized as difficult to treat with tyrosines. Atrazine is used to provide control throughout the season in corn, sorghum and other crops at a suggested rate of 2 pounds of active ingredient per acre. At sufficiently high rates, for example, that applied in this example, atrazine is recognized for its ability to provide non-selective weed control. In sandy soil, three replicates of each test were performed on plots of 12 feet X 25 feet using a randomized complete block pattern. Weeds were 2-6 inches (5-15 dm) tall when applying the treatment. Atrazine was applied in aqueous solutions at rates equivalent to either 1 or 2 pounds of active ingredient per acre. BP01 concentrate was added to atrazine in an amount equivalent to either 0.5"or 1 fluid ounce per acre (0.5-1 X 1010 CFU per acre) For comparison purposes, crop oil concentrate (approximately 85%) was used. of paraffinic oil and approximately 17% surfactant) as is conventional with triazine herbicides to increase its effectiveness Table 4-8 reports the degree of control for Richardia Sabra (Table 4), Muhlenbergia Emersleyi (Table 5), Pasture Bermuda (Picture 6), Chamomile Hedionda (Picture 7) and Primula (Picture 8).
Table 4 - Richardia Sabrá Table 5 - Muhlenbergia Emersleyi Table 6 - Bermuda grass Table 7 - Smelly Chamomile Table 8 - Primula From Tables 4-8, it can be seen that BP01 generally improved the effectiveness of atrazine at 23 days after treatment. The control rate at 1 Ib. of atrazine with the bacillus was better than the control rate of 2 Ib. of Atrazine for Bermudagrass, Hedionda Chamomile and Primrose, and both treatments had the same control rate for Muhlenbergia Emersleyi. Only with the Richardia Sabrá and 1 lb / acre atrazine with BP01 the control rate relative to the treatment of 2 lb / acre with atrazine was reduced. Similarly, BP01 also improved the atrazine control rate in relation to a mix of atrazine and harvest oil concentrate in all the weeds except for Richardia Sabrá and Primula. Said improvement suggests that the bacillus is not acting as a surfactant, but improving the efficacy of either the metabolic activity or the translocation characteristics, or both, of the agent applied together. The foregoing is solely for the purpose of illustrating the invention and is not intended to limit the scope of the appended claims.
