Abstract
The invention discloses a composite pesticide E imidacloprid guanidine and belongs to the technical field of prevention and treatment through pesticide. The weight ratio of the E imidacloprid guanidine to ethofenprox is 1:60-60:1. The composite pesticide further comprises an additive and a carrier, wherein the E imidacloprid guanidine and the ethofenprox occupy 5%-60% of the total weight of the pesticide, the additive occupies 5%-30% of the total weight of the pesticide, and the rest is the carrier. Through actual tests, the composite pesticide has obvious control efficiency on rice planthoppers. Compared with a conventional pesticide, the composite pesticide has the following advantages that the composite pesticide has the obvious synergistic effect on the rice planthoppers compared with a single pesticide, can obviously improve the control efficiency, replace parts of intermediately and highly toxic pesticides, reduce dosage, lower environment pollution and residuals in agricultural products and delay pesticide resistance of the rice planthoppers to the single pesticide, is long in lasting period, and can reduce cost compared with the single pesticide.
Description
Technical field
The invention belongs to the pesticide control technical field, relate to a kind of rice hoppers insecticide of preventing and treating.
Background technology
Rice fulgorid (comprises rice fulgorid, small brown rice planthopper, white-backed planthopper) be a kind of migrate very capable (except small brown rice planthopper), there is high intrinsic rate of increase, when condition is suitable, population often increases rapidly, very easily break out and cause disaster, therefore, chemical control is to control the most effective approach of rice fulgorid population, since the eighties, the control medicament is with Buprofezin, Imidacloprid, organic phosphor and built agent thereof are main, in Rice Production, play an important role, especially novel super-high-efficient chlorination nicotinic insecticide-Imidacloprid of developing in the mid-90, good to rice fulgorid quick-acting, lasting effect is long, consumption is few, to people and animals' low toxicity and and environmentally compatible, become rapidly the main pesticide species of preventing and treating rice hoppers, due to single for a long time, extensive use continuously, be equivalent to the rice fulgorid resistance screening extensive in field, rice fulgorid produces obvious pesticide resistance to Imidacloprid, control efficiency sharply descends, the pesticide species of effectively controlling at present rice fulgorid on Rice Production also lacks very much, although new pesticide species is arranged to be released, but cost accounting is too large, and the use of single pesticide species, rice fulgorid easily develops immunity to drugs.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of insecticide that contains penta pyrrole worm guanidine and ether chrysanthemum ester of preventing and treating rice hoppers with better control efficiency.
The composite insecticide that contains penta pyrrole worm guanidine and ether chrysanthemum ester of the present invention, its active ingredient is penta pyrrole worm guanidine and ether chrysanthemum ester, wherein the weight ratio of penta pyrrole worm guanidine and ether chrysanthemum ester is 1:60-60:1; Also include auxiliary agent and carrier in said composition, wherein penta pyrrole worm guanidine and ether chrysanthemum ester account for the 5%-60% of insecticidal total weight, and auxiliary agent accounts for the 5%-30% of insecticidal total weight, and all the other are carrier.
Wherein said auxiliary agent is lauryl sodium sulfate, ethoxylated dodecyl alcohol, lignosulfonates, sulfonic acid polyformaldehyde condensation product (NNO), polyethylene glycol, ammonium sulfate, sodium carboxymethylcellulose, sodium butylnaphthalenesulfonate, 1-METHYLPYRROLIDONE, alkyl benzene calcium sulfonate, phenethyl phenol mela mine-formaldehyde resin polyoxy ethyl ether, ethylene glycol, silicone compound, xanthans, aluminium-magnesium silicate.
Wherein said carrier is kaolin, diatomite, water.
The composite insecticide that contains penta pyrrole worm guanidine and ether chrysanthemum ester of the present invention can be water dispersible granules, wetting powder or aqueous emulsion.
Insecticide of the present invention, through actual test, has significant control efficiency to rice hoppers.
Composite insecticide of the present invention is compared with common insecticides, has the following advantages: 1, with single dose, compare this kind rice fulgorid is had to obvious synergistic effect, can significantly improve control efficiency; 2, high malicious insecticide in can Substitute For Partial, reduce dosage, reduce the residual of environmental pollution and agricultural product; 3, can delay the pesticide resistance of rice fulgorid to single insecticide, 4, have advantages of that the lasting period is long, with single medicament, compare, can reduce costs.
