Description
Technical field
The present invention relates to agricultural insecticide compositions and application thereof, specifically with methoxyfenozide and efficient fluorine chlorine
Cyano chrysanthemate and Radix Sophorae Flavescentis are the Pesticidal combination of effective ingredient, are applied to the preventing and treating of lepidoptera pest on crops.
Background technology
Radix Sophorae Flavescentis, Chinese medicine name.For the dry root of leguminous plant Radix Sophorae Flavescentis, excavate in spring, season in autumn two, remove root head and little supporting root, wash
Only, it is dried, or takes advantage of fresh slices, be dried.It is bitter, cold.There are heat clearing and damp drying, parasite killing.
The resistance problems of agricultural pests is a global problem, the emphasis that always agricultural science and technology worker pays close attention to
Problem.Along with the continuity year in year out of Chemical Control of Harmful Insects, the increase of Pesticide use amount and not scientifical use pesticide etc.
Factor, causes pest resistance day by day serious, and the pest species producing resistance is on the increase.Meanwhile, the use pesticide of high intensity, lead
Caused Practice for Pesticide Residue in Agricultural Products to exceed standard, pollute the series of problems such as environment and peasant's drug cost increase, be unfavorable for agricultural can
Sustainable development.
Therefore, develop efficiently, low toxicity, the different mechanism of action, have again the compound product of synergistic function simultaneously, do not only have
Help delay the generation of pest resistance to insecticide, but also the service life of pesticide species can be extended, reduce using dosage, save into
This, reduce the pollution to environment.
Methoxyfenozide (methoxyfenozide): belong to bishydrazide insecticide, is a kind of insect growth regulator, IGR.
After pests medicament, i.e. produce reaction of casting off a skin and start to cast off a skin, cause larva dehydration, hungry and dead owing to not casting off a skin completely
Die.It is mainly used in preventing and treating the larva of lepidoptera pest, such as beet armyworm, Prodenia litura, Pieris rapae, bollworm, apple leaf miner, U.S.
The white moth of state, pine moth, looper and the snout moth's larva of rice etc..
Betacyfluthrin (beta-cyfluthrin): belong to pyrethroid insecticides, has and tags and stomach toxicity
Effect.Insecticidal spectrum is wide, knock down height rapid, active, the lasting period is long, can be used for lepidoptera pest on Oryza sativa L., Cotton Gossypii, fruit tree and vegetable
Preventing and treating.Simultaneously can also the subterranean pest-insect such as control of grubs, Gryllotalpa, wireworm and cutworm.
Through retrieval, do not find methoxyfenozide and betacyfluthrin at present and Radix Sophorae Flavescentis is compounding and the document of application.
Summary of the invention
It is an object of the invention to provide a kind of Pesticidal combination containing Radix Sophorae Flavescentis, this complex composition has significantly
Synergistic function, be applied to lepidoptera pest rice-stem borer on crops, yellow rice borer, rice leaf roller, cotton boll worm,
Apple skin worm, vegetable Prodenia litura, beet armyworm, diamondback moth, the preventing and treating of Pieris rapae.
Technical scheme: a kind of Pesticidal combination containing Radix Sophorae Flavescentis, it is characterised in that: effective ingredient is that methoxyfenozide is with efficient
Cyfloxylate and Radix Sophorae Flavescentis extractive liquid, methoxyfenozide and betacyfluthrin and Radix Sophorae Flavescentis extractive liquid are in Pesticidal combination
Weight ratio is 1:1:1.
The auxiliary element used in the present composition includes solvent, emulsifying agent, wetting agent, disintegrating agent, stabilizer, dispersion
Agent, thickening agent, penetrating agent, pH adjusting agent, defoamer, antifreezing agent, carrier etc. are of value to effective ingredient and stablize in the formulation and send out
Waving the known substance of drug effect, be all conventional in pesticidal preparations or the various compositions of permission use, concrete composition and consumption are according to joining
Fang Yaoqiu is determined by test.
Frequency of administration and the amount of application of the present composition have small variations with crops, insect, weather condition change,
The purpose effectively prevented and treated can be reached by using suitable dosage.
Compared with prior art, it is an advantage of the current invention that:
1, the present invention has synergistic function, is used alone than single dose and significantly improves the prevention effect to insect；
2, the present invention is respectively provided with the different mechanism of action, can delay the generation of pest resistance to insecticide；
3, effective ingredient of the present invention compounds, and reduces Pesticide use amount, reduces use cost and the pollution to environment.
