Abstract
The present invention discloses pesticide composition which mainly contains 1 to 5% of hexaflumuron and 5 to 20% of carbosulfan. The present invention can be processed into emulsifiable solutions, powder, wettable powder, micro-emulsion, etc. The present invention has special effects on controlling beet armyworms, delays pesticide resistance generated by pests, and has the advantages of high pesticide effects and low cost. Simultaneously, the present invention has better control effects on other pests, such as thrips, aphids, cabbage worms, wireworms, whiteflys, scale insects, peach fruit borers, oriental fruit moths, beet flea beetles, etc., on vegetables, fruit trees and cotton.
Description
Technical field
The invention belongs to pesticide field, specifically relate to a kind of fluorine bell urea carbosulfan insecticides.
Background technology
Beet armyworm (Spodoptera exigua Hbn.) belongs to Lepidoptera, Noctuidae.Beet armyworm distributes very wide, is a kind of worldwide pest of difficult control.The larva wax coat of beet armyworm is thicker, and soup is difficult for infiltration, and feeding habits are assorted, and breeding is fast, and usually generation overlap has seemingly-dead phenomenon.Along with the adjustment of China's pattern of farming, the Different Crop intercropping is for beet armyworm provides sufficient foodstuff in recent years.In the many areas of China, the Winter-Spring weather is warm partially, and the insect population radix of surviving the winter rises, and arid is short of rain continuously to add summer, for beet armyworm the adapt circumstance condition is provided, cause the beet armyworm outburst to cause disaster.The beet armyworm large tracts of land takes place, and harm is serious, and crop seedling is injured and is caused large quantities of seedling death, forms and seriously is short of seedling, even ruin kind; Become strain leaf portion to be injured, cause serious hole or incise, influence the outward appearance and the quality of product, fruit is injured, and causes rotten and comes off.The conventional pesticide of Shi Yonging for many years, drug effect obviously reduces.At present, the special agent that is used to prevent and treat beet armyworm both at home and abroad also seldom, rare several prices are also very expensive, seriously lack efficient, low-cost, safely, delay the medicament of pest resistance to insecticide.

The purpose of this invention is to provide a kind ofly has efficient, the safety of special control efficiency, cost low to beet armyworm, and can delay the fluorine bell urea and the composite insecticides of carbosulfan of pest resistance.
Summary of the invention
A kind of insecticides mainly contains fluorine bell urea and carbosulfan.
According to well known to a person skilled in the art method, the present invention can be processed into any one formulations of pesticide such as missible oil, pulvis, wetting powder, microemulsion.
Above-mentioned insecticides mainly contains fluorine bell urea 1～5% (percentage by weight, down together), carbosulfan 5～20%.
Be that example is described in detail the present invention below with the cream preparation:
The invention described above insecticides cream preparation is made up of fluorine bell urea 1～5%, carbosulfan 5～20%, emulsifier 5～25% and solvent 30～85%;
Solvent described in the invention described above insecticides cream preparation can be any one or two to three kinds of the combination of toluene, dimethylbenzene, phenmethylol, acetone, dimethyl formamide, cyclohexanone and solvent known in those skilled in the art.
Emulsifier described in the invention described above insecticides cream preparation can be 0201,500
#, 602,2201,700
#, Tween-80, Tx-10 and emulsifier known in those skilled in the art any one or two to three kinds of combination.
The invention described above insecticides cream preparation can also contain bleeding agent, and it consists of: by fluorine bell urea 1～5%, carbosulfan 5～20%, emulsifier 5～25%, solvent 30～85% and bleeding agent 0.5～20%.
Bleeding agent described in the invention described above insecticides cream preparation is any one or wherein any two kinds combination of diesel oil, sesame oil, azone, machine oil, peregal, JFC and bleeding agent known in those skilled in the art.
Advantage that the present invention has and beneficial effect: (1), quick-acting, high efficiency: the result by repetition test shows, during 1000～2000 times of uses of compounded pesticides of the present invention, demonstrate after 48 hours the beet armyworm preventive effect is reached more than 90%, demonstrate quick-acting preferably and high efficiency; (2), the mechanism of action uniqueness, the compound synergic effect is remarkable: fluorine bell urea and carbosulfan belong to the pesticide compositional of different mechanism of action types, and be many to the insect action site; By the composite insecticide that forms of the present invention, have compound synergic effect when higher, and a preparation stabilization, the antagonism insect also has the better prevention effect, has reached to overcome and delay the purpose that pesticide resistance takes place; (3), the lasting period is long: the field demonstration result shows that compounded pesticides of the present invention is when using for 1000～2000 times, and the 15th day preventive effect to beet armyworm still reaches more than 65% behind the medicine, demonstrates lasting effect preferably; (4), safety is good: fluorine bell urea and carbosulfan are degraded in environment easily, and be free from environmental pollution, environmentally safe; Simultaneously,,, be public nuisance-free agricultural chemicals, meet the requirement of world's pollution-free food crop safety to people and animals' low toxicity; (5), insecticidal spectrum is wide: the present invention has very strong synergy preventive and therapeutic effect to beet armyworm; Simultaneously, can prevent and treat other insect on vegetables, fruit tree, the cotton such as diamond-back moth, aphid, cabbage caterpillar, wireworm, aleyrodid, scale insect, peach fruit borer, oriental fruit moth, beet flea beetle, colorado potato beetle, two spotted spider mite, codling moth, apple cecidomyiia etc.
