Description
Technical Field
The invention relates to the technical field of pesticide chemistry, in particular to an insecticidal composition, the active components of which contain bromofenoxaprop-p-fluorobenzamide and emamectin benzoate 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 the single compound of the brofenpyrad fluorobenzene diamide or the emamectin benzoate 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.

In another aspect, the present invention also provides a method of preventing or controlling pests by applying the pesticidal composition of the present invention to the target pests and/or their environment.
The present invention also provides a method for preventing or controlling pests comprising applying the pesticidal composition of the present invention to seeds, target useful plants or soil in which plants grow or soil suitable for plant growth.
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 seeds are selected from soybean, wheat, barley, rice, rape, sugar beet, tomato, cotton and corn 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, one aspect of the pesticidal compositions of the invention is capable of providing optimum protection of the seeds and germinating plants against attack by pests without damage to 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.

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 proportions of the brotrochan fluorobenzene diamide and the emamectin benzoate through a large number of screening tests, finds that the obtained insecticidal composition has a gain effect within a certain proportion range, is not only simple addition of two medicaments, and is specifically described with 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 flubendiamide and the emamectin benzoate are respectively dissolved by DMF to prepare 1% mother liquor, and then distilled water containing 0.05% Tween 80 is used for preparing the dosage required by the test. 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 brotrochan fluorobenzene diamide and the emamectin benzoate. Respectively diluting into five series of concentrations, and respectively placing in beakers for later use. Then soaking the leaves which are not contacted with any medicament and have the same size in the prepared liquid medicine for 5s by adopting a method of soaking the leaves firstly and then inoculating the insects, taking out the leaves, naturally airing the leaves, and putting the leaves into the prepared liquid medicineInoculating larva to insect breeding box, breeding at 25 deg.C, repeating for 3 times, checking number of dead insects for 72 hr, calculating mortality and correcting mortality, calculating virulence 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
