Abstract
The invention discloses a pesticide composition containing cyhalodiamide and methoxyfenozide. The pesticide composition is characterized in that the active ingredients are cyhalodiamide and methoxyfenozide in a weight ratio of (10 to 1)-(1 to 10); the rest of the ingredients are common auxiliary ingredients of pesticide preparations. The pesticide composition has obvious synergistic effects, has obviously better control effects than single agents used independently, also reduces the pesticide usage amount and the pesticide residues on the crops, reduces environmental pollution and delays the pesticide resistance of diseases and insect pests.
Description
Technical field
The present invention relates to composition pesticide and application thereof, specifically a kind of to take chlorine fluorine cyanogen insect amide and methoxyfenozide be active ingredient composition pesticide, is mainly used in the Lepidoptera class pest on control crops.
Background technology
Chlorine fluorine cyanogen insect amide is phthalic diamides novel pesticide, is mainly used in preventing and treating lepidopterous larvae on crops, and diamond-back moth, striped rice borer, rice leaf roller are had to good control efficiency.
Methoxyfenozide is a kind of novel specific phenylhydrazide class low toxic pesticide, and lepidoptera pest is had and highly selects insecticidal activity, take action of contace poison as main, and has certain systemic action.This medicine belongs to bionic type moulting hormone class.Insect takes food after medicament, produces the reaction of casting off a skin and starts to cast off a skin, and causes larva dehydration, hungry and dead owing to not casting off a skin completely.This medicine is contrary with the mechanism of action of the medicament that inhibition insect casts off a skin, and can prevent and treat in the whole larval phase medication of insect.Methoxyfenozide is mainly used in preventing and treating the larva of lepidoptera pest, as beet armyworm, tomato moth, prodenia litura, dish are agree worm, cotton bollworm, apple leaf miner, fall webworm, pine caterpillars, looper and the snout moth's larva of rice etc., applicable crops is as brassicaceous vegetable, solanaceous vegetables, melon, cotton, apple, peach, paddy rice, forest etc.
The inventor conducts in-depth research the compounded formula screening of chlorine fluorine cyanogen insect amide and methoxyfenozide, be surprised to find that chlorine fluorine cyanogen insect amide and methoxyfenozide carry out composite, within the scope of certain compound proportion, there is obvious synergistic function, in actual use, lepidoptera pest on crops is had to outstanding preventive effect, after further study, completed the present invention.
Summary of the invention
The object of the invention is different chlorine fluorine cyanogen insect amide and the methoxyfenozides of the mechanism of action to be mixed, the preventive effect of mixture is got a promotion, drug effect is more lasting, avoid the use of single agricultural chemicals, cause the generation of resistance, thereby reduce the usage amount of agricultural chemicals, lower the negative effect in agricultural chemicals use procedure, environment being caused.
Technical scheme of the present invention: a kind of composition pesticide that contains chlorine fluorine cyanogen insect amide and methoxyfenozide, take chlorine fluorine cyanogen insect amide and methoxyfenozide as active ingredient, the weight ratio of chlorine fluorine cyanogen insect amide and methoxyfenozide is 10:1～1:10, the percentage by weight of the weight summation of chlorine fluorine cyanogen insect amide and methoxyfenozide in composition is 0.1%～85%, and all the other are in agricultural chemicals, to allow to use and acceptable auxiliary element.
Described auxiliary element is one or more the combination in solvent, emulsifier, wetting agent, dispersant, stabilizing agent, antifreezing agent, thickener, disintegrant, binding agent, defoamer, bleeding agent, synergist, fire retardant and filler, above material is known substance conventional in pesticidal preparations, according to being prepared into the different formulations of pesticide, change to some extent, but be not particularly limited.
Composition pesticide of the present invention can be prepared into and be applicable to the upper multiple application forms using of agricultural, and reasonable formulation has suspending agent, water dispersible granules, wetting powder.
The production technology of the described various application forms of composition pesticide all belongs to existing known technology, does not repeat them here.
Product described in the invention can finished product preparation form provide, in composition, each material mixes, the form that the composition of composition also can single dose provides, and before use, directly in tank or bucket, mixes, and is then diluted to needed concentration.The frequency of administration of the present composition and amount of application change with weather condition and crop state variation.
Beneficial effect of the present invention is:
1, chlorine fluorine cyanogen insect amide and methoxyfenozide mixed synergies are obvious, and drug effect is greatly improved, and dosage obviously reduces, thereby have reduced use cost, reduce the residual and pollution to environment of agricultural chemicals.
2, in field trial observation process, we also find, the above-mentioned formulation of this formula processing, and lasting medicine, has effectively delayed the rising repeatedly of insect population number, has reduced spraying times, and the production that has reduced to a certain extent peasant household drops into.
Embodiment
In order to understand better essence of the present invention; below in conjunction with embodiment, content of the present invention is described further; but can not be considered as limitation of the present invention; the following stated is only for explaining the present invention; for not departing from modification, replacement or the improvement that the present invention is spiritual and principle is made, all belong to the scope of protection of present invention.
Embodiment mono-: indoor biological activity determination.
Former medicine is made to missible oil to be tested indoor feeding striped rice borer; Experimental Method in Laboratory carries out with reference to monarch Wu Wen < < chemical protection of plant experimental technique introduction > > (1993); by calculating the co-toxicity coefficient (CTC) of different complex preparations, different ratios is carried out to drug effect comparison, thereby determine the best mixed proportion of effect.Result of the test is with reference to following table.
Table 1, chlorine fluorine cyanogen insect amide, the methoxyfenozide toxicity test result to rice-stem borer that is mixed
According to the abundant method of Sun Yun, calculate the toxicity index of each medicament and the co-toxicity coefficient of mixture (CTC value), when CTC≤80 are antagonism, 80 ﹤ CTC ﹤ 120 are summation action, and CTC >=120 are synergistic effect.
Known according to table 1, after chlorine fluorine cyanogen insect amide, methoxyfenozide are composite with the ratio of 1:10-10:1, rice-stem borer is all shown to synergistic effect.
Bis-: 25% chlorine fluorine cyanogen insect amide methoxyfenozide wetting powders of embodiment.
By above-mentioned mixing of materials, after mechanical disintegration, again through air-flow crushing, mix, can make 25% chlorine fluorine cyanogen insect amide methoxyfenozide wetting powder.
