Abstract

An efficient insecticide for the pests such as aphid, plant hopper, leafhopper, etc. is prepared from penetrant (5-40%), imidacloprid (1-15%) and additive (45-90%), and features low dosage, high safety, quickly taking its effect, and durable effective period and broader spectrum.

Description

A kind of efficient pesticides

The present invention relates to a kind of efficient pesticides, effective insecticidal agent such as multiple sucking insect such as especially a kind of antagonism aphid, plant hopper, leafhopper.

At present, the medicament that is used for controls of insect such as paddy rice, cotton, fruit tree, wheat, peanut, vegetables is buprofezin more effectively, and this survival dose is big, and control efficiency is low, and control worm kind is few, and effective time is short.

The objective of the invention is to overcome the deficiency of above-mentioned prior art, and provide a kind of dosage few, the insecticide safe, quick-acting, that the lasting period is long.

Purpose of the present invention can realize by following measure, a kind of efficient pesticides, and the Imidacloprid of its bleeding agent by 5%-40%, 1%-15% and the additive of 45%-90% are formed.

Purpose of the present invention can also reach by following measure, the best proportioning of bleeding agent, Imidacloprid, additive is 10%-35%, 2.5%-10%, 55%-80%, bleeding agent is meant fatty alcohol-polyoxyethylene ether, secondary octanol APEO, additive is meant silica and precipitated calcium carbonate, and the ratio of the two is 1: 1.

Compared with the prior art the present invention has following advantage; (1) vigor of tagging is big, is 10.4 and 14.6 times of buprofezin.This insecticide can optionally suppress the acetylcholinergic receptor in the insect nervous system, it is the effector molecules of nAChR in the insect central nervous system, show high competition binding ability with this acceptor, thereby destroy the normal conduction of insect nervous centralis, so this insecticide shows very strong insecticidal activity; (2) consumption few and have very strong quick-acting, hold and imitate and residual effect.The field shows, the effective dose of pouncing on lice aphid control paddy rice brown planthopper, white-backed planthopper, leafhopper and thrips is a 1-2 gram/mu, the 1/5-1/20 field efficacy feature that is the buprofezin routine dose shows as quick-acting (1-3 days) highlightedly, holds effect (4-10 days), three sections effects of residual effect (more than 11 days); (3) this insecticide is lower and to aquatic organism safety to animal toxicity; (4) insecticidal spectrum is wider, has comprised most of crops such as tree, vegetables.Its insecticidal spectrum is wider, has comprised Homoptera, Semiptera, thrips, coleoptera, diptera, orthoptera Isoptera and part lepidoptera pest.

10% this insecticide and 25% buprofezin WP control brown plant-hopper effect contrast (for details see attached table).

So the present invention is only efficient, only because each percentages of ingredients of this compound method is suitable, especially contain the proper proportion Imidacloprid, this component is a kind of nitro methylene compound, it can optionally suppress the acetylcholinergic receptor in the insect nervous system, it is the effector molecules of nAChR in the insect central nervous system, show high competition binding ability with this acceptor, thereby destroy the normal conduction of the nervous centralis of insect, therefore, show high insecticidal activity for this efficient pesticides.Provide several embodiment below:

Embodiment 1 gets the silica of fatty APEO 5g, Imidacloprid 2g and 1: 1 and precipitated calcium carbonate mixture 50g at normal temperatures and mixes and get final product.

Embodiment 2 gets secondary octanol APEO 40g at normal temperatures, and Imidacloprid 2g and 1: 1 silica and precipitated calcium carbonate mixture 70g mix and get final product.

Embodiment 3 gets fatty APEO 20g at normal temperatures, and Imidacloprid 7g and 1: 1 silica and precipitated calcium carbonate mixture 60g mix and get final product.This insecticide of 10% and 25% buprofezin WP control brown plant-hopper effect comparison sheet subordinate list was handled behind the worm amount medicine of mu consumption sub-district behind 2 days medicines behind 7 days medicines 15 days
