Abstract

The present invention discloses a compounded pesticide of chlorfluazuron and profenofos or DDVP, which belongs to the technical field of compounded pesticides. The compounded pesticide of chlorfluazuron and profenofos comprises 0.5 to 10 percent of chlorfluazuron and 10 to 40 percent of profenofos. The compounded pesticide of chlorfluazuron and DDVP is characterized in that the compounded pesticide of chlorfluazuron and DDVP comprises 0.5 to 10 percent of chlorfluazuron and 20 to 60 percent of DDVP. The cotoxicity coefficient of the compounded pesticide of chlorfluazuron and profenofos or DDVP reaches 102 to 217, the disinsection range is wide, the effect on preventing and controlling pests of lepidoptera, coleoptera, hymenoptera, diptera, thysanoptera, etc. is good, the preventing and controlling rate reaches 95 to 100 percent, the quick effect and the durable effect are good, and the use cost is low and is about 58 to 60 percent lower than that of a chlorfluazuron pesticide.

Description

Fluorine pyridine urea and Profenofos or atgard mixed pesticide
Technical field
The invention belongs to technical field of compounded pesticide.
Background technology
Fluorine pyridine urea has another name called UC 62644, presses down hooligan, IKI-7899, CGA112913, is a kind of phenyl formoxyl urea insecticide, insect based on stomach poison function, is had concurrently stronger action of contace poison, poor permeability, no systemic action.It is a little matter enzyme inhibitors of insect, suppresses chitinous formation, hinders insect and normally casts off a skin, and makes ovum hatching, larval molting, pupa development deformity, and the emergence of adult, lays eggs etc. to be obstructed and to bring into play insecticidal action.Very high to the insect activity, but speed of action is slower, can very fast death behind the larva contact medicine, but food ingestion obviously weakens.This medicine has very high activity to some insects such as multiple lepidoptera pest and 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.Safer to natural enemy, honeybee, fish, but silkworm is had certain toxicity, be to be more satisfactory insecticide in the current integrated pest control, but quick-acting is poor, medicine valency cost is higher.
Summary of the invention
For overcoming the problems referred to above, the object of the invention is to provide the technical scheme of insects such as a kind of cost is low, insecticidal spectrum wide, control Lepidoptera, coleoptera, Hymenoptera, diptera, thrips effective and quick-acting, the lasting effect urea of fluorine pyridine preferably and Profenofos or atgard mixed pesticide.

The chemical name of dichlorvos is O, O, and-dimethyl-O-(2.2.-dichloro) vinyl phosphate is known substance, can be buied by former Shanghai insecticide factory.
Described fluorine pyridine urea and Profenofos or atgard mixed pesticide can be made into missible oil, promptly former medicine solubilizer and emulsifier.Concrete composite production technology and usual auxiliaries all belong to existing known technology, do not repeat them here.
Described fluorine pyridine urea and Profenofos or atgard mixed pesticide, co-toxicity coefficient reaches 102-217, insecticidal spectrum is wide, insects such as control Lepidoptera, coleoptera, Hymenoptera, diptera, thrips are effective, control efficiency reaches 95~100%, quick-acting and lasting effect are better, and use cost is low, reduce about 58-65% than fluorine pyridine urea agricultural chemicals.
Proportioning in the present patent application is the weight percentage of the pure material of active ingredient.

Analyze above-mentioned data, measurement result shows that the co-toxicity coefficient of fluorine pyridine urea and Profenofos different proportion prescription all has obvious synergistic effect all greater than 100.With 30% fluorine pyridine urea Profenofos missible oil (prescription two) co-toxicity coefficient maximum, consider that wherein 30% fluorine pyridine urea Profenofos missible oil (prescription two) can be used as prioritization scheme and selects from pesticide cost and drug effect.
Measurement result shows, the co-toxicity coefficient of fluorine pyridine urea and dichlorvos different proportion prescription is all greater than 100, both composite summation actions that are essentially.Consider that from pesticide cost and drug effect 40% fluorine pyridine urea DDT EC (prescription five) can be used as prioritization scheme and selects.
Find out from the effect table of above-mentioned fluorine pyridine urea and Profenofos missible oil control prodenia litura: 30% fluorine pyridine urea Profenofos missible oil uses 1000,2000 times of liquid control prodenia lituras, the insect population slip is respectively that the insect population slip is respectively 100% and 97.0% after 100% and 92.5%, 7 day after 3 days.Behind the medicine 3 days composite dose all better than two contrast medicament fluorine pyridine ureas, Profenofos, behind the medicine 7 days, 1000 times of liquid were consistent with the drug effect that contrasts medicament, 2000 times of liquid preventive effects also reach 93.3%.
From reagent cost, 30% fluorine pyridine urea Profenofos missible oil is roughly equal to 50,000 yuan/ton, and 120,000 yuan/ton of 5% 5 percent of hexaflumuron emulsifiable concentrate, reagent cost can descend about 58%.
Find out from the effect table of above-mentioned fluorine pyridine urea and atgard mixed dose of control prodenia litura: 40% fluorine pyridine urea DDT EC is used 1000,2000 times of liquid control prodenia lituras, the insect population slip is respectively 92.8% and 90.7% after 3 days, proofread and correct preventive effect and be respectively 90.1% and 87.1%, the insect population slip is respectively 96.4% and 97.7% after 7 days, proofreaies and correct preventive effect and is respectively 87.7% and 92.2%.Behind the medicine 3 days composite dose all better than two contrast medicament fluorine pyridine ureas, dichlorvos, 7 days drug effects of composite dose are with single close with 5% 5 percent of hexaflumuron emulsifiable concentrate behind the medicine.
From reagent cost, 40% fluorine pyridine urea DDT EC is roughly equal to 4.2 ten thousand yuan/ton, 120,000 yuan/ton of 5% 5 percent of hexaflumuron emulsifiable concentrate, and every 100g that uses per mu, the cost of composite dose (1000 times of liquid) descends 65%.
