Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a herbicidal composition for controlling weeds in rice cultivation.

[0002]

BACKGROUND OF THE INVENTION Anilofos can be used to control annual grass weeds and sedges in transplanted rice [Handbook of Herbicides, British Crop Protection Council, 9th Edition, 36th Edition]. Page (Pesticide Manual, British Pro
t. Council, 9th Ed., p.36)].

It is as early as 198 that anilophos can be combined with 2,4-dichlorophenoxyacetic acid (2,4-D) in order to extend the range of action against broadleaf weeds.
Listed in 1 year. This is the Echinochloa
spp.) and platypus (Ischaemum sp.) and annual grasses and Cyperus difformi
s), Kogomegaya (Cyperus iria) and Hiderico (Fim
Not only sedges such as bristylislittoralis) but also broad-leaved plants such as eel (Monochoria vaginalis), Sphenochlea zeylanica and Ludwigia octavalis have been successfully controlled.

JP-A-54-160737 (German Patent Application Publication No. 2,821,509 and British Patent No. 2)
020,978), anilofos and 2,4-
It has been disclosed that a mixture with D, MCPB, naproanilide, diamurone and bentazone shows a synergistic effect when used to control rice weeds.

[0005]

On the other hand, in rice cultivation in Japan and Southeast Asia, it is known that there are weeds whose control using the above combinations cannot always be sufficiently successful. These include, among others, the mosquitoes (Sagittaria spp.)
(Eleocharis spp.), Cyperus serotinu
s) and fireflies (Scirpus juncoides), as well as other weed species that germinate primarily from perennial organs in the soil that make them more difficult to control compared to seed-germinating weeds. Also included.

[0006]

Surprisingly, the present inventors have now found, in a biological greenhouse experiment using a group of herbicidally active substances, that, when used concomitantly, a wide range of Shows very good action against weeds,
And also, we found a new synergistically active combination that is extremely tolerant to rice. They are superior in action and effect as compared to known herbicides and combinations of herbicides and can be used in low dosages.

Other advantages of these novel combinations are:
It is a long-lasting effect that lasted for several weeks, which can eliminate subsequent application of herbicides to newly germinated weeds. Controlling overgrown weeds by destruction by a single application makes the second operation unnecessary.

Particular examples of the active substance mixtures according to the invention include, but are not limited to: anilofos + bensulfuron-methyl 〃 + 〃 + daimlon anilofos + pyrazosulfuronethyl 〃 ＋ 〃 ＋ Daimron Anilophos ＋ Cinosulfuron 〃 ＋ 〃 ＋ Daimron Anilofos ＋ TH913〃 ＋ 〃 ＋ Dymron Anilofos ＋ AC014〃 ＋ 〃 ＋ Dymron The use of Dimuron in these combinations is 2
It has one distinct advantage: on the one hand it enhances herbicidal action against cyperus (Cyperus spp.) And grass weeds, on the other hand dimuron also acts as a safener for rice plants, and For example, it reduces the potential phytotoxicity that may be incurred by herbicides such as sulfonylurea derivatives. A detoxifying effect for the combination of JC-940 and anilofos has also been found.

Similarly, it was observed that anilofos has a surprising toxic-reducing effect in the combination of anilofos and pyrazosulfuron. The potential phytotoxicity to rice caused by pyrazosulfuron itself or in admixture with other herbicides is reduced or completely compensated by anilofos. This active substance combination thus exceeds the previously known effects and exhibits new properties, which are found in a totally unexpected and surprising manner.

The herbicidal compositions according to the invention have an outstanding herbicidal action against a wide range of economically important monocotyledonous and dicotyledonous harmful plants. The combinations of these active substances also act effectively on perennial weeds which germinate from rhizomes, root fragments or other perennial organs and which are difficult to control. In this context, it is immaterial whether these substances were applied before planting, before germination or after germination. Some representatives of the monocotyledonous and dicotyledonous weed plant groups which may be controlled by the composition according to the invention may be mentioned in particular, but are not intended to be restricted to a particular genus.

Examples of weed species for which the composition described above acts effectively are the monocotyledonous plants and the annual vegetative snails and the perennial varieties of the perennial snails.

The active substance combinations according to the invention are, for example, those of the genus Urikawa (Sagittaria), the family Omodaka (Alism).
a), yellow cypresses (Rotala), eels (Monochori)
a), species of pine nuts (Eleocharis), species of fireflies (Scirpu
s), enables excellent control of weeds that can be found under certain conditions of rice cultivation, such as Cyperus and others.

If the herbicidal composition according to the invention is applied to the surface of the soil before germination, the seedlings of the weeds are completely prevented from germination or the weeds reach the cotyledon stage, but After their growth ceases and eventually after 3 to 4 weeks, they die completely.

If the active substance combination is applied post-emergence to the green parts of the plants, the growth likewise stops dramatically very quickly after the treatment. Weeds either remain in the growth stage at the time of application or they die more or less rapidly after a certain time, and thus the competition with weeds harmful to cultivated plants is By using the novel composition according to the invention, it is removed at a very early time point and continuously.

The composition according to the invention has an excellent herbicidal action against monocotyledonous and dicotyledonous weeds, whereas the rice plants are harmless to no or negligible harm. . For these reasons, these compositions are highly suitable for selectively controlling unwanted plants, especially in rice.

By using the active substance combinations according to the invention, a herbicidal action is achieved which exceeds the activity expected on the basis of the activity of the individual components. These increased effects allow a substantial reduction in the amount of individual active substance applied. Herbicidal combinations may also improve their sustained action or accelerate the rate of action. Such properties are of great benefit to the user when actually controlling weeds. It allows the weeds to be controlled more economically, faster, less laborious and more persistent for the user, thus obtaining a greater yield of cultivated plants.

Furthermore, the fact that the combination of active substances in a series exhibits an excellent alleviation or detoxification effect, ie the toxic side effects of the active substances used are reduced or completely avoided in cultivated plants, such as rice.

The mixing ratio of the various components can be varied within wide limits. They depend in particular on the components used, the stage of weed development, the type of weed and the weather conditions. The active substance combinations according to the invention can be present in the form of mixtures of the two components, which are then diluted with water in the usual way or else the components which are prepared separately are mixed. And can be produced as a so-called tank mix by diluting this mixture with water.

The formulations (combinations) can be formulated in various ways, depending on the predominant biological and / or chemo-physical parameters. Examples of suitable possible formulations are: Wettable powders (WP), emulsions (EC), aqueous solutions (SL), emulsions (EW) such as oil-in-water and water-in-oil emulsions, sprays. Solutions or emulsions, oily or aqueous dispersions, suspoemulsions, dusts (DPs), seed treatments, but especially soil and dusting granules, or water-dispersible granules (WG), ULV formulations,
Microcapsules or wax.

Pre-germination effect on weeds Seeds or rhizome pieces of monocotyledonous and dicotyledonous weed plants are planted and covered with sandy loamy soil in plastic pots 9 cm in diameter. The weeds found in rice cultivation are cultivated in flooded soil with an amount of water placed in the pot such that the water reaches the surface of the soil or overflows to a depth of a few millimeters. Combinations of the active substances according to the invention formulated as wettable powders or emulsions and those individual active substances also formulated in parallel in experiments carried out in parallel are applied at an application rate of 300 to 600 l of water per ha (converted). In different amounts) in the form of aqueous suspensions or emulsions on the surface of the soil cover in various proportions, or in the case of rice, poured into irrigation water.
After treatment, the pots are placed in a greenhouse and kept under good growth conditions for weeds. A visual evaluation of the negative effect on plant damage or germination was carried out after the test plants had a test period of 3 to 4 weeks, compared to untreated controls.
The herbicidal composition according to the present invention exhibits excellent preemergence herbicidal activity against a wide range of grass and broadleaf weeds.

In all cases, the degree of effect calculated was different from the effect found in the combination.
The calculated degree of effect of the theoretically expected combination is
SR Colby formula: Calculation of synergistic and antagonistic response of herbicide combinations ("Calculation of syn
ergistic and antagonistic responses of herbicideco
mbinations ", Weeds 15 (1967), pages 20-
22)).

In the case of a combination of two active substances, this formula is:

[0064]

[Chemical 28]

And, therefore, in the case of a combination of three herbicidally active substances:

[0066]

[Chemical 29]

In the above formula,% damage by herbicide A at an application rate of X = x kg / ha; Y =% damage degree by herbicide B at an application rate of y kg / ha; Z = z kg / ha % Damage by herbicide C at application rate; E =% damage expected by herbicide A + B (or A + B + C) at E = x + y (or x + y + z) kg / ha.

If the actual damage exceeds the damage expected by the calculation, the action of the combination is superadditive, ie there is a synergistic reaction. The active substance combinations according to the invention have a herbicidal activity (calculated by Colby's formula) which exceeds the activity expected on the basis of the activity of the individual components observed when applied individually. This means that the combination of active substances is synergistic. 2. Post-emergent herbicidal action on weeds: Monocotyledonous and dicotyledonous weed seeds or rhizome fragments are placed in sandy loamy soil in soil-covered plastic pots and in a greenhouse under good growth conditions. Grow in. The surface of the soil is 2
Cultivated in pots submerged in water to a depth of cm and allowed to grow for the duration of the experiment. Three weeks after sowing, the 3-leaf stage test plants are treated.

Combinations of the active substances according to the invention formulated as wettable powders or emulsions, and in the comparative experiments the individual active substances formulated in the same manner, were applied at an application rate of 300 to 600 liters of water per ha (calculated in terms of conversion). In different amounts, and spraying the test plants in the greenhouse for 3 to 4 weeks under ideal growth conditions.
The effect of the formulation is evaluated visually by comparison with untreated controls. In the case of the weeds found in rice or rice cultivation, the active substances are also added directly to the irrigation water (application similar to the so-called granule application) or sprayed into the plants and the irrigation water. The compositions according to the invention also have a good postemergence herbicidal action against a wide range of economically important grass and broadleaf weeds. According to the Colby method analysis, the composition according to the invention has a synergistic effect.

Example of the toxic-reducing effect of Dimuron (B8) and JC-940 (B12) on anilophos Rice was transplanted in a greenhouse into sandy soil in plastic pots and cultivated until the 2.5 leaf stage was reached. did. The soil surface was flooded to a depth of 3 cm over the entire experimental period.

The treatment with the substances according to the invention was then carried out individually and in the form of their mixtures by pouring the products suspended or emulsified in water into submerged water in pots.

The phytotoxicity to rice was then evaluated after about 3 weeks of treatment by measuring the fresh weight of the shoots of the test plants. The table below shows the experimental data obtained and the expected values calculated by Colby's equation. The values shown in the table show that both Daimlon and JC-940 have a very significant effect on the reduction of phytotoxicity to rice caused by anilofos, ie both herbicides have a significant toxicity to anilofos. It clearly proves to have a relaxing effect. For all variants of the mixture, the expected value calculated by Colby's equation is considerably lower than the actual value measured for the combination in question.
