Definitions

  • the present invention generally relates to methods for improving disease resistance in plants without adversely affecting the plant growth. More specifically, the present invention is directed to methods for achieving such results by treating the plant tissue with an ortho- substituted benzoic acid and an organic amine.
  • Agricultural pesticides are used to control unwanted fungal, viral, and bacterial populations. These compounds have allowed the producer to manage disease pressure. Although, these traditional chemical applications have been valuable in the past it is unlikely that the producer will be able to use them at the same rate into the future. Therefore, improved methods for controlling disease by stimulating the plant's natural processes are desirable. For some years it has been known that plants have the ability to produce pathogenese proteins. Once these proteins are expressed plants may have the capacity to protect themselves from pathogenic insults. The efforts of individuals, chemical producers, and academic institutions are now concentrated on producing genetically manipulated species that either repress or express these enzymes or their perceived precursors. Innumerable compounds have been documented as inducers of the pathogenese proteins. However, because the compounds applied separately induce a given set or class of enzymes they have not been found to be efficacious in preventing infection in field hosts.
  • An inoculation with an array of elicitors would induce the expression of recessive enzymes of two or more classes. These enzymes would enable the treated plant to defend itself against pathogens.
  • Plants are continually under attack from pathogenic microorganisms.
  • the pathogenic insults from the exposure to fungal, viral, and bacterial assaults are frequently confined to the area of attack. These insults often cause lesions as the cell dies.
  • the cell death is part of a hypersensitive reaction (HR) to the pathogen.
  • HR hypersensitive reaction
  • This reaction acts as an inoculant for the lesion forming pathogen, and also, as an inoculant for unrelated pathogens.
  • This inoculation provides a systemic acquired resistance (SAR).
  • SAR systemic acquired resistance
  • the pathogenese proteins are chitinese enzymes
  • Class I catalytic activity, cystine rich (protein spacer between amino and carboxyl ends) - ethylene induced.
  • Auxins have been shown to induce expression of ethylene at very low concentrations when applied. They are also useful for the inducement of chitinase. Auxins have also been shown to induce a class of pathogenese proteins. Sugars have also been shown to induce ethylene biosynthesis.
  • Systemic resistance is typically characterized by a reduction in lesion size.
  • the lesion response is a programmed cell death to isolate the pathogen and prevent further infection.
  • the pathogenese related proteins When the pathogenese related proteins are expressed prior to disease inoculation the pathogens can be isolated within the lesion in a shorter time period. It has been postulated that those substances that induce pathogenese related proteins would prime the plant for disease resistance, if applied prior to the insults.
  • the infection resistance is not the same for all cultivars or pathogens.
  • the lesion size for a given infection can be inversely correlated with the dose of the inducing chemical administered and, if application of a given set of inducers at a concentration great enough to induce production of an array of pathenogese related proteins, then the pathogen insult could be minimized to the extent that no signs of infection would be visible. That is to say, there would be no visible lesion formation.
  • auxins a class of plant hormones, have been shown to promote the production of the gas in plants at low concentrations, i.e., Auxins may be used to elicit pathogenese related proteins for plant defense. Because Auxins have been well studied and auxin structure activity relationships have been identified, synthetic compounds with auxin like biological characteristics are readily contrived. Naturally occurring Auxins typically have an indole core structure. The indole becomes biologically active with either auxin or anti-auxin like activity with molecule functionality substitution. With the use of resonance structures the structural similarities are easily seen.
  • benzothiadiazoles and their derivatives as biologically active materials may be actually mimicking Auxins.
  • the relationship between ethylene and Auxins has been well documented.
  • the promotion of pathogenese related proteins from exposure to ethylene is also well documented, e.g., the use of Auxins and other ethylene elicitors for the purpose of inducing an array of pathogenese related proteins is now documented.
  • Ethylene is also documented to be expressed from injury to a plant. If one were to compare pathogenese related protein production from known elicitor applications then the difference in those proteins induced would be from either concentration applied, compound applied, or compounds application method. Because the amount of pathogenese related enzymes expressed is roughly proportional to the amount of inducer applied and because lesion size is proportional to the amount of pathogenese related protein produced, the amount of an inducement elicitor applied should maximize the promotional properties of the inducement elicitor without causing harm. For salicylic acid an optimum concentration would be greater than 75mM.
  • Phenolics are plant growth inhibitors. Natural growth inhibitors (phenolics) are found in growing and dormant plants, fruits and seeds. These compounds are thought to work in concert with the phytohormones to regulate the growth and development of organisms throughout their life cycle.
  • Salicylic acid application has also been found to inhibit ethylene biosynthesis, inhibit germination, block wound responses, interfere with membrane ion transport and absorption of roots, induce rapid membrane depolarization and collapse of the transmembrane electrochemical potential, reduce transpiration in leaves and epidermal strips, reverse ABA induced stomatal closure, affect leaf abscission, and affect growth inhibition. These responses will almost certainly cause a decrease in the potential yield of a crop.
  • United States Patent No. 5,654,414 to Ryals, et al states ". . .
  • the chimeric gene may need to be expressed at levels of 1% of the total protein or higher. This may be the case for fungal resistance due to increased proteinase inhibitor expression. In cases where the energy expended to produce high levels of foreign protein may result in a detriment to the plant whereas, expression of the gene only when desired, for instance when a fungal or insect infestation is imminent, would result in reduced drain on energy, and therefor yield.
  • salicylic acid has a Ka of 1 .05 X 10 "3 it would not generally exist as a protonated acid in the xylem, phloem or cytoplasm; a conjugate base or ester would probably exist in such an environment.
  • weak bases specifically amines
  • for the neutralization of the weak acid would mimic the naturally occurring compounds as found in nature.
  • High concentrations of phenolics have been found in the presence of amines during flowering.
  • Substituted phenyl compounds have long been known to inhibit the growth in plants. Nonetheless, some phenolic acids are known to induce the production of proteins that provide the SAR.
  • the SAR acts as an immunity response that protects the plant against fungus, bacteria, and virus. This response is generally triggered from interactions between the plant and pathogen, i.e., viral, fungal, and bacterial agents.
  • the immune response is a systemic gene expression that requires phenolic accumulation.
  • the SAR generally lasts weeks to months.
  • the cuticle is soluble in alcohol or ketone.
  • hydroxyl, carbonyl, or ketal functional groups in combination with the chelated metal ions may aid in the cation permeability through the cuticle to the plant cell.
  • copper salts either applied to the leaf or soil, when present in the cell at 10 to 100 times the amount necessary for normal growth and development, may control pathogens. Because of the efficacy of chelated copper the amount of copper salt necessary at an application to the soil or the plant itself to raise the copper content in tissue analysis is lowered.
  • the present invention is directed to processes for improving pant resistance to disease without inhibiting plant growth. These processes are broadly directed at treating the plant with an ortho-substituted benzoic acid and nitrogen-containing compounds that is selected from the group consisting of the organic amines and compounds which will metabolize to an organic amine. These processes have been found to be further improved by simultaneously treating the plant with a chelated micronutrient metal. Finally, even more improvement has been observed where the plant is further treated with an ethylene inducing compound. Alternatively, it has been found that the benzoic acid and derivatives and nitrogen-containing compounds may be applied as an amine salts of the substituted benzoic acid. The acid, nitrogen containing compound, and optionally, chelated micronutrient metal and ethylene-inducing compounding, should be applied to the foliage of the plant as a solution flocked with a suitable carrier medium.

The plants were severely damaged by the application and death of some plants followed.
  • the metals were provided in a form of the oxides chelated with citric acid and monoethanolamine. This concentrated solution was diluted 50 to 1 with water. The concentration of components in the following solution was about 0.0015M amine salt of salicylic acid, 0.006M each copper (II) and zinc(ll) and 0.007M mangenese (II). Commercial available Auxin (indole-3-butyric acid) was added as an ethylene- inducing compound. The solution so prepared, together with a control of water, was applied to Gerber Daisy infected with powdery mildew. A single foliar application was found to prevent infection. Subsequent applications of the same solutions applied at two week intervals continued to prevent infection.

  • Celery was successfully treated in accord with the present invention by a similar solution.
  • a final solution containing salicylic acid, an amine, chelated micronutrient metals and an ethylene-inducing compound was prepared in accord with that described in Example 3.

While no disease was present, an increase in biomass and size was recorded at harvest. Control plants were treated with water. Using a sample of thirty treated and thirty controlled, biomass and size were recorded at harvest. Harvest mass of the controlled plants averaged 1.04kg per plant while those treated with the salicylic acid/amine solution averaged 1.32kg per plant. Height of the plants was also increased from an average of 61cm to 64cm. Thus, treatment in accord with the present invention, far from stunting or inhibiting plant growth, resulted in a 5 percent increase size, together with a 27 percent increase in biomass.
  • Corn was treated with a solution in accord with that prepared in Example 3 except that a 50:1 dilution with water was used. While disease was not present during the growing period, an increase in grain mass was recorded at harvest. Average yield per acre at harvest for controls (treated with water) was about 181.9 bushels per acre; average for the portion of the field treated in accord with the present invention was about 192.5 bushels per acre. In both cases nitrogen was applied at a rate of 100 pounds per acre.
  • Example 7 Red Oak Lettuce was successfully treated in accord with the present invention in an experiment conducted at the University of Queensland in Australia. A single spray at early seedling stage soon after planting prevented disease. Further, significant increases both diameter and height were observed.
  • Example 8 A treatment solution in accord with that described in Example 3 above was prepared and foliar applied to the plants at early seedling stage. Ten plants were treated with that solution while an additional ten plants were maintained as a control treated with water. Average plant diameter increased from 25.2cm to 27.7cm, an increase of about 10 percent. Similarly, average plant height increased from 14.8 to 16.7cm, an increase of about 13 percent. Thus, not only did treatment of growth in the present invention prevent disease, but surprisingly produced significant increase in yield.

Ratings were graded on a visual scale from 1 to 5; of the roots graded 1 with no sign of infection while root showing severe pythium damage were rated 5. Treatment in accord with the present invention increased average plant diameter from 18.93cm to 23.07cm, an increase of 22 percent.
