Abstract

The present invention belongs to the technical field of composite pesticides, particularly to a composite triflumuron pesticide which is characterized in that the composite triflumuron pesticide comprises the components of 0.3 to 10% of triflumuron, 10 to 50% of clorpyrifos, 0.3 to 10% of triflumuron and 10 to 50% of malathion. The composite triflumuron pesticide has the cotoxicity coefficient of 128 to 457, high efficiency, favorable lasting performance, wide disinsection range and lower cost which is 65 to 80% lower than that of a single triflumuron preparation, and has the favorable effect of preventing and killing lepidoptera injurious insects, particularly for the injurious insects of noctuids having drug resistance, such as beet armyworms, phytometra circumflexa, cotton bollworms, etc.

Description

A kind of bell urea Recompounded pesticide that kills
Technical field
The invention belongs to technical field of compounded pesticide.
Background technology
Insect growth regulator, IGR has been the world's numerous countries development at present and has produced; become the 4th generation pesticide species;, Teflubenzuron, volt bell urea, worm hydrazides, capillary grand, kill bell urea, Buprofezin etc., all belong to the acylureas insecticides, worm, mite are had tag and stomach poison function as the pyridine worm.Such agricultural chemicals belongs to chitinase inhibitors, suppresses chitinous formation, hinders insect and normally casts off a skin, make it become deformity and death is higher to the insect activity, but speed of action is slower, can very fast death behind the larva contact medicine, but food ingestion obviously reduces, dead gradually.Such agricultural chemicals has very high activity to insects such as multiple Lepidoptera, orthoptera, coleoptera, Hymenoptera, dipteras, it is the insecticide of comparison wide spectrum, the insect that insecticides such as organic phosphor, carbamate, pyrethroid are developed immunity to drugs has good control efficiency, natural enemy, honeybee, fish etc. are compared safety, poisonous to silkworm.In current integrated pest control, especially in the production of non-polluted farm product the comparatively ideal insecticide of an analogy.
Killing the bell urea is one of insect growth regulation, and it is to lepidoptera pest, especially to there being drug-fast noctuidae pests to have the better prevention effect.But this class agricultural chemicals quick-acting is poor, and at present price is higher, as replace in some of high-toxic pesticide with present China, hypotoxic organic phosphor, pyrethrin pesticide be composite, will increase quick-acting, reduction pesticide cost.
Summary of the invention
In view of the above problems, the object of the invention is that a kind of quick-acting and the lasting effect that provide are better, insecticidal spectrum broad, lower-cost technical scheme of killing bell urea Recompounded pesticide.
Described a kind of bell urea Recompounded pesticide that kills is characterized in that: kill bell urea 0.5～2.5%, chlopyrifos 20～30%.
Described a kind of bell urea Recompounded pesticide that kills, it is characterized in that: killing bell urea content is 1～2%, and chlopyrifos content is 20～30%.
Described a kind of bell urea Recompounded pesticide that kills is characterized in that: kill bell urea 0.5～2.5%, malathion 35～40%.
Described a kind of bell urea Recompounded pesticide that kills, it is characterized in that: killing bell urea content is 1～2%, and malathion content is 35～40%.The chemical name that kills the bell urea is: 2-chloro-N[[[4-(fluoroform chloro) phenyl] amino] carbonyl] benzamide; 1-2 (2-chlorobenzene formacyl)-3-(4-Trifluoromethoxyphen-l) urea is known substance, can be buied by Jilin Tonghua Pesticide Chemical Co., Ltd..
The chemical name of chlopyrifos is: O, and O ,-diethyl-O-(3,5, the 6-trichloro-2-pyridyl) thiophosphate is known substance, can be buied by Zhejiang Xinnong Chemical Co., Ltd or Xinanjiang River chemical industry joint-stock company.
The chemical name of malathion is: O, O ,-dimethyl-S-[1,2 ,-two (ethoxy carbonyl) ethyl] phosphorodithioate, be known substance, can buy by Ningbo insecticide factory.
Described a kind of bell urea Recompounded pesticide that kills can make missible oil (former medicine adds organic solvent and emulsifier), also can be processed into colloidal suspending agent.Former medicine, organic solvent or water add a series of auxiliary agents (as wetting agent, dispersant, tackifier, stabilizing agent, antifreezing agent, defoamer etc.), grind through sand mill to form.
Described a kind of bell urea Recompounded pesticide that kills, co-toxicity coefficient reaches 128-457, and quick-acting and lasting effect are better, the insecticidal spectrum broad, cost is lower, than reducing by 65～80% with killing bell urea list agent cost.Be current control lepidoptera pest, especially, the better prevention effect arranged as beet armyworm, prodenia litura, cotton bollworm etc. to drug-fast noctuidae pests is arranged.Proportioning in patent application of the present invention is weight content.
Embodiment
The following stated embodiment describes the present invention in detail.In an embodiment, unless otherwise indicated, all percentages all are weight percentage.

Adopt the feed infusion process, measurement result to prodenia litura 3 instar larvaes shows: the co-toxicity coefficient of the different proportion of bell urea and chlopyrifos prescription is all greater than 100 extremely, all has obvious synergistic effect, wherein with 25% virus killing missible oil (prescription two) co-toxicity coefficient maximum, reach 457, consider that from pesticide cost and drug effect angle 25% virus killing missible oil (prescription two) can be used as optimization of C and selects;
The co-toxicity coefficient of the different proportion of bell urea and malathion prescription is all greater than 100 extremely, all has obvious synergistic effect, wherein kill bell urea malathion missible oil (prescription six) co-toxicity coefficient maximum with 40%, reach 141, consider that from pesticide cost and drug effect angle 40% kills bell urea malathion missible oil (prescription six) can be used as the optimization of C selection.
Show through field trial: the prodenia litura 3-4 instar larvae that takes place with the taro field is an object, and 25% kills 1000 times of bell urea chlorpyrifos ecs (mu medication 50ml), and 3 days, 7 days control efficiency all reach 100% behind the medicine; With behind 2000 times of (mu medication 25ml) medicines 3 days, control efficiency was 95.6%, and behind the medicine 7 days, control efficiency reached 97.1%; Single kill 1000 times of bell urea missible oil (mu medication 50ml) with 10%, behind the medicine 3 days, control efficiency was 57.0%, and 7 days control efficiency are 93.2% behind the medicine; Single control efficiency was 93.8% with behind 500 times of 40% chlopyrifos (mu medication 100ml) medicine 3 days, and behind the medicine 7 days, control efficiency was 94.4%.The control efficiency of killing the single agent of bell urea and chlopyrifos is all low than the control efficiency of killing bell urea chlorpyrifos mixture agricultural chemicals;
The prodenia litura 3-4 instar larvae that takes place with the taro field is an object, and 40% kills 1000 times of bell urea malathion missible oil (mu medication 50ml), and 3 days, 7 days control efficiency all reach 100% behind the medicine; With behind 2000 times of (mu medication 25ml) medicines 3 days, control efficiency was 92.2%, and behind the medicine 7 days, control efficiency reached 93.2%; Single kill 1000 times of bell urea missible oil (mu medication 50ml) with 10%, behind the medicine 3 days, control efficiency was 57.0%, and 7 days control efficiency are 93.2% behind the medicine; Single control efficiency was 83.9% with behind 500 times of 45% malathions (mu medication 100ml) medicine 3 days, and behind the medicine 7 days, control efficiency was 85.6%.The control efficiency of killing bell urea malathion Recompounded pesticide all is better than single agent.
The poisoning phenomenon does not take place to trial crops in above-mentioned agricultural chemicals.
