Description

Insecticidal composition

Technical Field

The invention relates to the technical field of pesticide chemistry, in particular to an insecticidal composition, which contains bromofenoxaprop-ethyl and methoxyfenozide as active components and a method for controlling pests.

Background

The rice stem borers, rice leaf rollers, tea geometrids, asparagus caterpillars, prodenia litura, diamond back moths, rice planthoppers, aphids, thrips, bemisia tabaci, greenhouse trialeurodes vaporariorum and mites are common pests on plants such as rice, wheat, corns, cottons, vegetables, fruit trees, tea leaves and the like. If no corresponding measures are taken against the pests, the growth of the agricultural plants must be influenced.

Chemical control is an important means of preventing and controlling pests in agriculture. However, currently, there are cases where effective control cannot be achieved due to the type of pest, living characteristics, living environment, and the like, which are poor in effect and strong in resistance. In particular, it is becoming increasingly difficult to control pests of the lepidoptera, coleoptera, diptera, homoptera, hemiptera, hymenoptera, thysanoptera, arachnida, and nematoda classes using conventional agents. Therefore, it is necessary to find a new means and method for effectively controlling pests which are impossible to control or difficult to control.

Brofanenfluorobenzene bisamide (Broflanilide) is a novel bisamide pesticide developed by Mitsui agricultural chemical company and Pasteur in Japan in a cooperative manner. The brofenpyrad fluorobenzene bisamide is mainly used for controlling lepidoptera, coleoptera, termites, mosquitoes and flies and other pests on crops such as green-leaf vegetables, perennial crops, grains and the like. Bromobenzophenone bisamide is known and described in EP3081552a 1; the molecular structural formula is shown as formula I:

a typical object that arises in the field of pest control is the need to reduce the dosage rate of active ingredients and to reduce or avoid adverse environmental or toxicological effects, while still allowing effective pest control, and the need for pest control agents that combine a fast acting and a long acting.

The activity of single compound of the brofenbendiamide or the methoxyfenozide is good; however, at low application rates or for particular pests, they sometimes do not meet the high requirements which must be met by pesticides.

The insecticidal composition is particularly suitable for controlling pests on cereal plants and vegetable plants.

The insecticidal composition is particularly suitable for controlling tea lesser leafhopper, chilo suppressalis, rice leaf roller, corn borer, tea geometrid, asparagus caterpillar, prodenia litura, diamond back moth, tea cutworm, tea leaf roller moth, apple fruit moth, pear fruit moth, soybean fruit moth, rice planthopper, thrips, gray plant hopper, brown plant hopper, pear psylla, bemisia tabaci, greenhouse whitefly, sogatella furcifera, frankliniella, thrips margaritifera, thrips flavus, green house thrips, tea yellow thrips, panonychus citri, apple panonychus ulmi, two-spotted spider mite, armyworm and flea beetle on cereals and vegetable plants.

The present invention also provides a method of protecting plants from pest attack comprising contacting the pesticidal composition of the present invention with the target useful plants, the target pests and/or their environment, propagation material of the target useful plants.

Use of the pesticidal composition of the present invention for treating seeds.

The insecticidal composition of the present invention is particularly preferably used for seeds of grain crops and vegetable crops.

The present invention also provides a method for protecting seeds from soil insects and for protecting the roots and shoots of seedlings from soil and foliar insects, which comprises contacting the seeds before sowing and/or after pregermination with an effective amount of the pesticidal composition of the present invention.

The insecticidal compositions of the present invention are suitable for treating seeds. Most of the damage caused by pests to crop plants occurs as early as infestation during storage of the seeds, after the seeds have been sown into the soil, and during and just after germination of the plants. This stage is particularly critical because the roots and shoots of growing plants are particularly sensitive and even minor damage can lead to death of the entire plant. Therefore, the protection of seeds and germinating plants by the use of suitable compositions is of critical importance.

The method of the present invention for protecting seeds does not require the additional application of crop protection agents to protect the seeds and germinating plants after planting or after emergence of the plants. At the same time, the insecticidal compositions according to the invention on the one hand provide optimum protection of the seeds and germinating plants from attack by pests, without at the same time harming the plants themselves as a result of the active compounds used. The treatment of seeds with the pesticidal composition of the present invention protects not only the seeds themselves, but also the grown plants after emergence from pests. This eliminates the need to treat the crop immediately at the time of planting or shortly thereafter.

Examples of the method of seed treatment include a method of diluting a liquid or solid chemical, a method of directly immersing seeds in a liquid solution without dilution to allow the chemical to permeate the seeds, a method of mixing a solid chemical or liquid chemical with seeds to coat the seeds and thereby adhering the chemical to the surfaces of the seeds, and a method of spraying the chemical to the vicinity of the seeds while planting. The seed to be subjected to the seed treatment is a plant body used in an early stage of cultivation for plant propagation, and examples thereof include, other than the seed, a plant body for vegetative propagation for cultivation of a bulbous root, a tuber, a potato seed, a plant bud, a bulb or a cutting. For the treatment of plant propagation material, in particular seeds, the active components can also be applied to the seeds by successively impregnating tubers or grains with a liquid preparation of the respective active component or by coating with a combined wet or dry preparation (coating).

The term "plant propagation material" is understood to mean all plant parts capable of propagation, such as seeds, and also plant material, such as cuttings or tubers (e.g. potatoes). Thus, plant parts as used herein include plant propagation material. Mention may be made, for example, of seeds (in the narrower sense), roots, fruits, tubers, bulbs, rhizomes and plant parts. Also contemplated are germinated plants and useful plants to be inhibited post-emergence or post-emergence from soil. The young plants can be protected prior to transplantation by a total or partial treatment by dipping.

A plant part and plant organ that subsequently grows is any part of a plant produced from plant propagation material, such as seeds. Plant parts, plant organs and plants may also benefit from protecting plants from plant diseases by applying the compositions to plant propagation materials. Certain plant parts and certain plant organs that subsequently grow can also be regarded as plant propagation material, which itself can be applied (or treated) with the composition; thus plants, other plant parts and other plant organs produced from the treated plant parts and treated plant organs may also benefit from protecting plants from plant pests by applying the compositions to certain plant parts and certain plant organs.

The pesticidal composition of the present invention is applied to seeds as such or in a suitable dosage form. Preferably, the seeds are treated in a steady state so that the treatment does not cause any damage. The treatment of the seeds can generally be carried out at any time between harvesting and sowing. It must generally be noted during seed treatment that the amount of the composition of the invention and/or the amount of other additives applied to the seed is chosen so as not to affect the germination of the seed or damage the resulting plant.

The pesticidal compositions of the present invention are particularly advantageous for treating plant propagation material, in particular cereal crops, vegetable seeds.

The insecticidal compositions of the present invention are particularly advantageous for the treatment of plant propagation material, in particular tea leafrollers, tea diamond back moths, beet armyworms, prodenia litura, diamond back moths, tea leafhoppers, striped rice borers, rice leaf rollers, corn borers, tea geometrid, apple budworms, pear budworms, soybean budworms, rice planthoppers, gray planthoppers, brown planthoppers, pear psyllids, bemisia tabaci, greenhouse whiteflies, sogatella furcifera, frankliniella occidentalis, thrips viridis, panonychus citri, panonychus ulmi, tetranychus urticae, armyworms, flea beetles on cereals, vegetable plants.

A method of protecting seeds comprising contacting the seeds before sowing and/or after pregermination with a synergistically effective amount of the pesticidal composition of the invention.

Seed treatment occurs on unsown seeds, and the term "unsown seeds" is intended to include seeds at any time between harvest of the seeds and sowing of the seeds in the ground for the purpose of germination and growth of the plant. Preferably, the treatment occurs before sowing of the seeds, whereby the sown seeds have been pre-treated with the combination. In particular, seed coating or seed pelleting is preferred in the treatment of the combination of the invention. After treatment, the components of each combination adhere to the seed and are thus available for pest control.

The seeds treated with the pesticidal composition of the present invention can be stored, managed, sowed and tilled.

The invention also provides a method for preventing or controlling pests, wherein the insecticidal composition provided by the invention is used for acting on target pests and/or the environment thereof.

The pesticidal composition of the present invention may be applied to the environment, habitat or storage area where plants are growing. The environment and habitat for plant growth refers to a support capable of rooting and growing the agricultural plant, such as: examples of the raw material include sand, pumice, vermiculite, diatomaceous earth, agar, gel, polymer, asbestos, wood chips, and bark, and soil is preferable.

Examples of methods for applying a chemical to soil include a method in which a liquid chemical is diluted in water or applied without dilution directly to the roots of a plant or a seedling bed for raising seedlings, a method in which granules are sown to the roots of a plant or a seedling bed for raising seedlings by spraying a powder, a water dispersible granule or the like to soil and mixing with the whole soil before sowing, and a method in which a powder, a water dispersible granule or the like is diluted and sprayed to a planting hole or a planting furrow before sowing or planting a plant, and sowing is performed.

The soil or culture medium of the plant in the practice of the method of use of the present invention refers to a support capable of rooting and growing the crop, for example: examples of the raw material include sand, pumice, vermiculite, diatomaceous earth, agar, gel, polymer, asbestos, wood chips, and bark.

On the other hand, the pesticidal composition of the present invention can also produce the following super-additive effect: improving plant growth, increasing tolerance to high or low temperatures, increasing tolerance to drought or to water or soil salt content, increasing flowering performance, making harvesting simpler, accelerating maturation, increasing harvest yield, improving the quality and/or nutritional value of the harvested product, improving the storage stability and/or processability of the harvested product.

The treatment of plants and plant parts with the insecticidal compositions of the invention is carried out in a conventional manner, either directly or by acting on their environment, habitat or storage area. Such as dipping, pouring, spraying, atomizing, broadcasting, dusting, fogging, broadcasting, foaming, coating, spreading, dripping, and the like. The frequency and amount of application can be adjusted to suit the degree of infestation by the pest.

The present invention also provides a method for protecting plants from pest infestation comprising the separate, sequential or simultaneous application of flubendiamide and methoxyfenozide.

It is common and advantageous for the pesticidal compositions of the present invention to be applied generally at the following dosages:

-for leaf treatment: 0.1 to 10000g/ha, preferably 10 to 1000g/ha, more preferably 20 to 300 g/ha;

The above-mentioned dosages are only typical exemplary dosages, and the application rates will be adjusted by the person skilled in the art in the actual application according to the actual circumstances and needs, in particular according to the nature of the plants or plants to be treated and the conditions of the pests.

Biological test example

The combination of the effective components of different pesticides into pesticides is an effective and quick way to develop and develop new pesticides and control resistant pests in agriculture at present. Pesticides of different species, when mixed, typically exhibit three types of action: additive action, synergistic action and antagonistic action. However, the specific action cannot be predicted, and can only be known through a large number of experiments. The compound formula with good synergy obviously improves the actual control effect and reduces the using amount of pesticide, thereby greatly delaying the generation speed of the drug resistance of pests and being an important means for comprehensively controlling the pests.

The inventor conducts a large number of tests and effect analysis on different ratios of the brobendiamide and the methoxyfenozide through a large number of screening tests, finds that the obtained insecticidal composition has a gain effect within a certain ratio range, is not only simple addition of the two agents, and is specifically described in the following embodiment.

In embodiments of the invention, an indoor virulence assay is used. And (3) according to the combined action measurement of part 7 of the pesticide mixing according to the agricultural industry standard (NY/T154.7-2009) of the people's republic of China in the pesticide indoor bioassay test rule, calculating the corrected mortality of each treatment according to survey data, and calculating the cotoxicity coefficient (CTC value) of the mixed pesticide according to the Sun cloud Peel method.

The co-toxicity coefficient (CTC) of the two medicaments compounded according to a certain proportion is determined, wherein the CTC <80 is antagonistic action, the CTC <80 > and < 120 is additive action, and the CTC > 120 is synergistic action.

The test method comprises the following steps: during the test, the brobendiamide and the methoxyfenozide are respectively dissolved in DMF as raw medicines to prepare1% of the mother liquor, then the dosage required for the test is prepared by using distilled water containing 0.05% of Tween 80. And then according to the set proportion, two single agents are respectively transferred according to the proportion to prepare the mother liquor mixed by the brofenflurane bisamide and the methoxyfenozide. Respectively diluting into five series of concentrations, and respectively placing in beakers for later use. Then soaking leaves which are not contacted with any medicament and have consistent size in prepared liquid medicine for 5s by adopting a method of soaking leaves firstly and then inoculating insects, taking out the leaves, naturally airing the leaves, putting the leaves into an insect breeding box, inoculating test larvae, breeding the larvae at the temperature of 25 ℃, repeating the treatment for 3 times, wherein the number of the test insects used in each repetition is 20, simultaneously setting a blank control, checking the number of dead insects in 72 hours, calculating the death rate and correcting the death rate, solving a toxicity regression equation and calculating LC₅₀The value is obtained. If the control mortality is greater than 10%, the test is considered invalid. The calculation formula is as follows:

death rate (%) - (number of living insects before drug-number of living insects after drug)/number of living insects before drug x 100

Corrected mortality (%) - (treatment-control mortality)/(100-control mortality) × 100

The corrected mortality for the test insects was converted to a probability value (y), the treatment concentration (. mu.g/ml) was converted to a logarithmic value (x), and a virulence regression equation was obtained by the least squares method, from which the value of each agent was calculated. And (4) calculating a co-toxicity coefficient CTC according to a Sun cloud Peel formula method.

The calculation formula is as follows (with the brotrochan fluorobenzene bisamide as a standard medicament and the toxicity index of the brotrochan fluorobenzene bisamide as 100):

measured toxicity index (ATI) ═ standard medicament LC₅₀Test agent LC₅₀)×100

Theoretical virulence index (TTI) ═ percentage of A in the A agent ATI × mixture + percentage of B in the B agent ATI × mixture

Cotoxicity coefficient (CTC) ═ (ATI/TTI) × 100
