Abstract
The present invention discloses a composite triflumuron pesticide and belongs to the technical field of composite pesticides. The composite triflumuron pesticide is characterized in that 0.3 to 10% of triflumuron and 20 to 70% of dichlorvos are contained, or the composite triflumuron pesticide is characterized in that 0.3 to 10% of triflumuron, and 0.5 to 5.0% of high-efficiency cypermethrin are contained. The cotoxicity coefficient of the composite triflumuron pesticide reaches 104 to 223, and the present invention has the advantages of favorable effect of preventing lepidoptera injurious insects with the prevention rate of 98.0%, high efficiency, favorable lasting performance and low using cost which is only 1/3 to 1/2 that of similar products.
Description
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 (as UC 62644, Teflubenzuron, fluorine bell urea, worm hydrazides, kill bell urea, Buprofezin etc.); all belong to the acylureas insecticides, worm, mite are had tag and stomach poison function.Such agricultural chemicals belongs to chitinase inhibitors, suppresses chitinous formation, hinders insect and normally casts off a skin, and makes it become deformity and death.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, and dead gradually.This agricultural chemicals has very high activity to insects such as multiple Lepidoptera, orthoptera, coleoptera, Hymenoptera, dipteras, 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.
Poor in view of this class agricultural chemicals quick-acting, 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
Based on the problems referred to above, the object of the invention is to provide a kind of insecticidal spectrum broad, cost is lower, the control lepidoptera pest is effective and quick-acting, lasting effect are killed the technical scheme of bell urea Recompounded pesticide preferably.
The described bell urea Recompounded pesticide that kills is characterized in that: contain bell urea 0.3-10% extremely, dichlorvos 20-70%.
The described bell urea Recompounded pesticide that kills, it is characterized in that: the content that kills the bell urea is 0.5-5%, and the content of dichlorvos is 30-50%.
The described bell urea Recompounded pesticide that kills, it is characterized in that: the content that kills the bell urea is 1-2%, and the content of dichlorvos is 40-50%.
The described bell urea Recompounded pesticide that kills is characterized in that: contain bell urea 0.3-10% extremely, beta-cypermethrin 0.5-5.0%%.
The described bell urea Recompounded pesticide that kills, it is characterized in that: the content that kills the bell urea is 0.5-5%, and the content of beta-cypermethrin is 1.5-5.0%.
The described bell urea Recompounded pesticide that kills, it is characterized in that: the content that kills the bell urea is 1-2%, and the content of beta-cypermethrin is 2.0-4.0%.
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; Be known substance, can buy by Jilin Tonghua Pesticide Chemical Co., Ltd..
The chemical name of dichlorvos is 0,0 ,-dimethyl-0-(2.2.-dichloro) vinyl phosphate; Be known substance, can buy by former Shanghai insecticide factory.
The chemical name of beta-cypermethrin is (IR cis) S and (IS cis) R-α cyano group-(3-benzyloxy phenoxy base)-3-(2, the 2-dichloroethylene)-2,2-dimethylcyclopropane carbonyl acid ester; Be known substance, can use r, buy by former Hangzhou insecticide factory.
The described bell urea Recompounded pesticide that kills can be made into missible oil, can be made by former medicine adding organic solvent and emulsifier.Concrete composite production technology and usual auxiliaries all belong to existing known technology, do not repeat them here.Certainly, press known technology, also can make colloidal suspending agent according to the technical program, promptly former medicine, organic solvent or water add a series of auxiliary agents again, grind through sand mill to form.
The described bell urea Recompounded pesticide that kills, co-toxicity coefficient reaches 104-223, and the control lepidoptera pest is effective, and control rate reaches 98.0%, and quick-acting and lasting effect are better, and use cost is low, only are about the 1/3-1/2 of like product.
Proportioning in the present patent application is the weight percentage of the pure material of active ingredient.

Adopt the feed infusion process, the measurement result of prodenia litura 3 instar larvaes is shown that co-toxicity coefficient that bell urea and the different proportion of dichlorvos extremely fill a prescription all greater than 100, all has obvious synergistic effect.Wherein kill bell urea DDT EC (prescription two) co-toxicity coefficient maximum with 50%, reach 146, consider from pesticide cost and drug effect angle, 50% kills bell urea DDT EC (prescription two) can be used as prioritization scheme and selects.
Adopt the feed infusion process, the measurement result of prodenia litura 3 instar larvaes is shown that co-toxicity coefficient that bell urea and beta-cypermethrin different proportion extremely fill a prescription all greater than 100, all has obvious synergistic effect.Wherein kill bell urea r (prescription ten) co-toxicity coefficient maximum, reach 223 with 4%,, but that it kills bell urea content is the highest, and cost is bigger; 4% to kill bell urea r (prescription six) co-toxicity coefficient be 168, but it is lower to kill bell urea content, and the lasting period is shorter; From pesticide cost, drug effect, hold many-side such as effect and consider that 4% kills bell urea r (prescription nine) and can be used as prioritization scheme and select.
Find out from above-mentioned data: 50% kills atgard mixed dose of 1000 times of liquid of bell urea (being every mu of dose 50ml), and 3 days preventive effects reach 97.6% after the medication; 7 days preventive effect is 96.8%; 2000 times of liquid (every mu of dose 25ml), 3 days preventive effects are that 83.7%, 7 day preventive effect is 89%.Quick-acting and the lasting effect of 1000 times of liquid is all good than two kinds of contrast medicaments.
4% kills that 3 days preventive effects are that preventive effect is 97.3% after 98%, 7 day after efficient cypermethrin compounded dose of 1000 times of liquid medications of bell urea; 2000 times of liquid after 3 days preventive effect be that preventive effect is 92.4% after 87%, 7 day; All the preventive effect than two kinds of contrast medicaments is good.
The poisoning phenomenon does not take place to trial crops in above-mentioned medicament.
Calculate from production cost, 50% to kill atgard mixed dose of pesticide cost per ton of bell urea be 21000 yuan, and producer price (comprising packing charge) is about 33000 yuan.Every mu with 50ml meter, and every mu pesticide cost expense is about 1.8～2.0 yuan.Killing every mu of 50ml of bell urea missible oil (about 4.0 yuan) than list with 10% is at half.
4% kills the cost price and the producer price and above-mentioned close of efficient cypermethrin compounded dose of bell urea.
