Abstract
High-efficiency anti-bollworm pesticide belongs to pesticide, is a kind of ternary built efficient insecticide agent emulsifiable solution that high resistant bollworm is used of preventing and treating.Current commercially available compounded pesticides, relatively poor to high resistant bollworm control efficiency, or, use safety inadequately to person poultry toxicity's height.High-efficiency anti-bollworm pesticide of the present invention can reach 85～89% to high resistant bollworm control efficiency, and lower to the person poultry toxicity, safe in utilization, and agricultural cost is low.Except that being used for cotton control resistant bollworm, also can doublely control cotten aphid, also can be used for wheat, insects such as control wheat aphid.
Description
The invention belongs to agricultural insecticide, particularly prevent and treat the organic insecticide of resistant bollworm.
Cotton be to use agricultural chemicals the earliest, one of maximum crops.Because the long-term agricultural chemicals that uses, insects such as cotton bollworm produce general, serious pesticide resistance to organophosphorus compounds, carbamates and the pyrethroid insecticides of routine.For example, before 1981,5000～6000 times of organophosphorus ester insecticides dilutions, 8000～10000 times of pyrethroid insecticides dilutions, control efficiency by 1992, is diluted 1000 times, 500 times all more than 90%, and control efficiency is less than 50% also.
By all kinds of combined use of pesticides one of feasible solutions that solve pest resistance to insecticide.At present the control efficiency of more existing complex preparation antagonism insects is not ideal enough, as binary built insecticides such as No. one, cotton boll treasured, new light, to the control efficiency 50-60% only of resistant bollworm at advanced age.Some complex preparation toxicity height, as the ternary built insecticides such as bell spirit, Mielingwei that go out all belong to the hypertoxic type agricultural chemicals, use dangerous.
The objective of the invention is to develop a series of antagonism cotton bollworms and have good control efficiency, efficient pesticides safe in utilization again.
Compounded pesticides of the present invention is to be pesticide active ingredient with 5a,6,9,9a-hexahydro-6,9-methano-2,4, phoxim and pyrethroid insectide, and is added with the ternary built missible oil that emulsifier, solvent complex form.
The used pyrethroid insecticides of compounded pesticides of the present invention comprises that decis, hundred controls agricultural pyrethroid insecticideses such as chrysanthemum ester, cyhalothrin, cypermethrin, Biphenthrin, fenpropathrin, sumicidin and esfenvalerate.
Compounded pesticides of the present invention, the emulsifier that is added are 0203,0204,0206BT, agricultural emulsifiers such as 2201.
Compounded pesticides of the present invention, the solvent that is added are the aromatic hydrocarbons organic solvent, are good with benzene,toluene,xylene especially.
Compounded pesticides of the present invention, the proportion of composing of its pesticide active ingredient 5a,6,9,9a-hexahydro-6,9-methano-2,4, phoxim and pyrethroid insectide be respectively ternary built missible oil total amount 5～28%, 5～40%, 0.2～4%(weight).The former medicine content of 5a,6,9,9a-hexahydro-6,9-methano-2,4 is with more than 94%, and Phoxim original medicine content is with more than 85%, and pyrethroid insectide content is being good more than 90%.The emulsification dosage that adds is the 2-15%(weight of ternary built missible oil total amount), the quantity of solvent of adding supplies 100% for outside deduction 5a,6,9,9a-hexahydro-6,9-methano-2,4, phoxim, pyrethroid insectide and the emulsification dosage.
High-efficiency anti-bollworm pesticide of the present invention prepares by following processing technology: at normal temperatures, solvent with amount of calculation joins in the preparing tank earlier, then under agitation, add its active ingredient 5a,6,9,9a-hexahydro-6,9-methano-2,4, phoxim and pyrethroid insectide successively, after the stirring and dissolving, add emulsifier, stirred again 30-60 minute, promptly make the missible oil of transparent homogeneous phase.
High-efficiency anti-bollworm pesticide of the present invention, through refrigerating 0 ± 1 ℃, the emulsibility test of 55 ± 1 ℃ of heat storages and room temperature stability test and missible oil all meets the specification requirement of missible oil product.
High-efficiency anti-bollworm pesticide of the present invention through toxicity test, is 180-196 to the co-toxicity coefficient of high resistant bollworm, and synergistic effect is remarkable.This medicament can reach 85-89% to the control efficiency of above resistant bollworm in 3 ages, and can doublely control insects such as resistance wheat aphid, cotten aphid.
