CN1309906A - Pesticide composition containing abamectin and lambda-cyhalothrin - Google Patents

Abstract

The invention relates to an emulsifiable composition made of two insecticidal and acaricidal agents abamectin, cyhalothrin, an emulsifier, and a solvent, or additional additives such as a synergist and a penetrating agent, and the application of the composition to control The method of various pests such as diamondback moth and harmful mites. The above two insecticides and acaricides are used in combination, or additionally contain a synergist or a penetrating agent, which has a very significant synergistic effect on diamondback moths and the like. The present invention processes it into a mixture to make it a high-efficiency, low-toxicity and broad-spectrum insecticide and acaricide, which is suitable for preventing and controlling pests and harmful mites on vegetables, fruit trees and crops, and has remarkable economic and social benefits.

Description

A kind of Olivomitecidin and Cyhalothrin composition pesticide of containing

The present invention relates to contain insecticidal/acaricidal agent Olivomitecidin (abamectin) and Cyhalothrin (cyhalothrin), reach the milk oil composition that synergist, emulsifier, solvent etc. are made.

Simultaneously, the present invention relates to use the method for this composition for preventing and controlling diamond-back moth, cabbage caterpillar and various pests and evil mite.Olivomitecidin is a kind of new antibiotic compounds, contains 8 components, is main component with avermectins A1a, A2a, B1a and B2a.This medicine is a kind of super-high-efficient, selectivity insecticidal/acaricidal agent, and exist cost an arm and a leg, speed of action is slower, continuous single use easily cause insect and evil mite to shortcomings such as generation resistance.

Cyhalothrin is a kind of pyrethroid insecticidal/acaricidal agent, and this medicine effect wide spectrum, the speed of knocking down are fast, and price is comparatively moderate.

The present invention finds that Olivomitecidin and Cyhalothrin were used with in 1: 20～5: 1, can contain Olivomitecidin 0.1～1.0% in this composition, Cyhalothrin 0.1～5.0%.Or contain 1～10% Butacide (PBO), 1～30% synergy phosphorus synergist such as (SV1).Or contain bleeding agents such as 1～3% azone (NT), 1～10% molten wax oil.Effective especially to diamond-back moth, cabbage caterpillar and multiple two spotted spider mite, its co-toxicity coefficient can reach 150～731.Olivomitecidin and Cyhalothrin are mixed by proper proportion, or add synergist PBO, SV1 etc. in addition, or add penetrant azone, molten wax oil etc. in addition, can significantly improve control efficiency to insects such as diamond-back moth evil mite, reduced use cost, also can delay the resistance generation of insect and evil mite Olivomitecidin.With these two kinds of medicaments is active ingredient, adds auxiliary agents such as emulsifier, solvent, or adds synergist, bleeding agent etc. in addition, and it is processed into this composition pesticide of missible oil.

The invention provides and a kind ofly be mixed, or add synergist or bleeding agent in addition, improve drug effect, reduce the Olivomitecidin consumption, reduce use cost, delay insect and evil mite method the Olivomitecidin resistance by medicament.

The present invention also provides a kind of method of using above-mentioned composition pesticide control diamond-back moth and various pests and evil mite.

The synergist that the present invention uses can be Butacide or synergy phosphorus etc.

The present invention can use azone (NT), molten wax oil etc. to make bleeding agent.The present invention can use emulsifier, solvent to be processed into missible oil by conventional method.

The present invention can be processed into missible oil and further be illustrated by following " example ", but is not limited thereto.Below all umbers all refer to weight.

Prescription by specification accompanying drawing in each example is processed into the missible oil of different size.Crude oil 1, synergist, solvent, emulsifier and other auxiliary agent are by measuring in the measuring tank, former medicine 2 measures through weighing, and sequentially in mixing kettle hybrid modulation become to meet the missible oil that product quality requires, be transported to the canning line can then, be packaged into the finished product of certain specification at last.
