Abstract
The fluorochloro cyano p-emulsifiable concentrate for preventing and killing farm pests is prepared by mixing cyfluthrim 0.2-15 wt% and parathion 20-35 wt% as effective components as well as emulsifier 10-20 wt%, synergist 5-10 wt%, penetrant 5-10 wt% and solvent the rest. The present invention has powerful stomach toxicity and contact killing effect as well as certain egg killing and acarid killing effect. With the features of high and lasting effect, wide pesticidal spectrum, low toxicity and little hazard to human and farm animal, it may be widely used for preventing and killing pests in crops.
Description
The present invention relates to prevent and treat the agricultural chemicals of crop pests, exactly is that a kind of cyfluthrin is to missible oil.
The insecticide of production at present and use chrysanthemum lipid, carbamate or organophosphorus insecticide is of all kinds, but discovered in recent years uses this insecticides separately throughout the year, the pesticide resistance of insect is more and more stronger, cause existing insecticide list agent result of use worse and worse, dosage and medication number of times increase again and again, both strengthened input cost, increased peasant's burden again crops.The pesticide resistance of crop pests has become the serious problems that world's technical field of pesticide needs to be resolved hurrily, especially the pesticide resistance with cotton-plant pest-insects cotton bollworm, cotton aphid is particularly outstanding, the area that has even to the stage that pasts medical help has to rely on artificial seizure to be eliminated.
The disclosed insecticidal preparation oxychloride emulsion as pesticide of Chinese patent CN9105692.0, adopting with dichlorvos, flolimat and efficient cypermethrin is that effective ingredient is carried out ternary built and formed.To be that active ingredient is composite by time chrysanthemum fat, parathion-methyl and isocarbophos form the disclosed bell spirit of going out of Chinese patent CN1067550.This class compounded pesticides obviously is better than single agent to the retarding action of pest resistance to insecticide development with to the preventive and therapeutic effect of insect pest.But synergy amplitude that mixture is composite and control efficiency are still little desirable.
The object of the present invention is to provide a kind of to the evil on the crops such as cotton bollworm have significantly delay pesticide resistance, synergy amplitude and control efficiency agricultural insecticide preparation-cyfluthrin to missible oil.
The objective of the invention is to realize by following technical solution, a kind of cyfluthrin is to missible oil, it is characterized in that: contain trifluoro cypermethrin (chemical name: alpha-cyano-3-phenoxy benzyl-3-(2-chloro-3,3,3 one trifluoro-propenyls)-2,2-dimethyl cyclopropane carboxylic acid fat) and parathion (to be 0.0-diethyl-0-(4-nitrobenzophenone phosphorothioate ester) be effective ingredient with chemical name, and being mixed with an amount of emulsifier, synergist, bleeding agent, solvent forms.
Its proportioning (percentage by weight) is:
Trifluoro cypermethrin 0.2-15
Parathion 20-35
Emulsifier 10-20
Synergist 5-10
Bleeding agent 5-10
The solvent surplus
Preparation processing method of the present invention is the conventional method of preparation pesticide liquid body preparation missible oil, with the packing afterwards that stirs of effective ingredient trifluoro cypermethrin and parathion and emulsifier, synergist, bleeding agent, solvent etc.
Synergist of the present invention can be synergy phosphorus (: O, O-diethyl monothio phosphoric acid benzene fat), Butacide (piperonyl butoxide).Emulsifier is the mixture (ratio is 3: 2) of alkyl polyoxy ethyl ether and calcium dodecyl benzene sulfonate.Bleeding agent can be selected bleeding agent fourth (sulfosuccinate fat) for use.Solvent is a dimethylbenzene.This missible oil outward appearance is yellow homogeneous liquid, does not have visible suspension and precipitation, and proportion is 0.9 ± 0.02, and acid-base value is (with H
2SO
4Meter)≤0.4%, moisture content≤0.5% can mix mutually with other agricultural chemicals.According to the routine techniques standard of measuring missible oil, all meet the technical indicator of international food and agricultural organization (FAO) and the relevant emulsifiable concentrates for agricultural chemicals of China and cold and hot and storage at normal temperature is stable.
The present invention is owing to select for use the trifluoro cypermethrin with cholinesterase in the inhibition insect bodies to mix cream preparation with using composite the forming of parathion that belongs to nervous poison, single agent action of agricultural chemicals mechanism of collection two classes and characteristic on the drug effect, insect had very strong tag, stomach poison function and certain ovum acaricidal action that kills, and having speed, to hold effect, efficient, wide spectrum, good stability and toxicity extremely less, dosage is low, environmental pollution is little, people and animals is endangered little; And cost is lower.Can be widely used in the control of various pests such as aphid, cabbageworm, rice fulgorid, rice leafhopper and cotton bollworm on paddy rice, wheat, cotton, fruit tree, the flowers and plants, cotton aphid, red worm septempunctata, two-spotted spider mite.
Embodiment:
0.5 kilogram of trifluoro cypermethrin, 24.5 kilograms of parathion-methyls, 12 kilograms of emulsifier (dodecyl polyoxy ethyl ether: calcium dodecyl benzene sulfonate is 3: 2), 8 kilograms of synergy phosphorus crude oil, 10 kilograms of bleeding agent fourths, 45 kilograms of solvent xylenes evenly are mixed into active ingredient and are 25% cyfluthrin.To missible oil.
Through carrying out the toxicity test test (subordinate list one, two) and the indoor control cotton bollworm test of pesticide effectiveness (subordinate list three) with the stronger cotton bollworm of the missible oil of the present embodiment antagonism property of medicine respectively and preventing and treating the cotton bollworm test of pesticide effectiveness (subordinate list four) in outdoor cell.The missible oil of proof present embodiment has comparatively significant synergistic effect to cotton bollworm; Under the situation to the fast longevity of residure length of cotton bollworm knockdown effect, same amount, the preventive effect of present embodiment is better than the preventive effect in 50%1605 missible oil and 2.5% time; And it is remarkable that this embodiment prevents and treats the cotton bollworm effect, dispenser one day after with three days, its average preventive effect is all more than 80%; Proofreading and correct preventive effect than single agent parathion time chrysanthemum fat effect remarkable (test of significance employing " DMRT " method), is a kind of comparatively desirable, compound insecticidal preparation of being worthy of popularization.
