Description
Technical field
The present invention relates to field of pesticides, and in particular to a kind of nematode that kills containing fluorine thiophene worm sulfone and Benfuracard micro combines
Thing.
Background technology
Fluorine thiophene worm sulfone (fluensulfone) is the new chemical nematicides of the only one developed in nearest more than 20 years, belongs to fluorine
For olefines sulfide compound, by action of contace poison in nematode, activity is reduced after nematode touches this material, and then is benumbed, cruelly
Stop feeding after dew 1h, infection ability declines, and egg production capacity declines, and egg hatching rate declines, and the larva of hatching can not survive, and it is not
Reversible nematocidal effect can make nematode dead.Because fluorine thiophene worm sulfone is to various plants parasitic nematode, including the root that harm is serious
Tie lines worm preventive effect is notable, while has toxicity low, and environmental risk is low, using it is simple the advantages of, it has in terms of nematode is prevented and treated
Good development prospect.But in a particular application, there are many problems in single sterilization component, such as：Dosage is big, development of drug resistance
It hurry up, drug effect is poor, restricted application etc..Therefore, compounding and its synergy turn into the direction of sterilization pesticide research and development now.
Benfuracard micro is the less toxic kind of carbofuran, is the inhibitor of cholinesterase, have tag, stomach toxicity and it is interior inhale make
With being mainly used in preventing and treating rice, cotton, corn and soybean, a variety of piercing mouth parts and biting mouth parts insects of vegetables and fruit tree, such as
Flea beetle, beetle, wireworm, diamondback moth, armyworm, leafhopper and aphid etc..
