Abstract

The wide-spectrum synergy insecticidal preparation that contains Amitraz, binary or ternary mixture that said preparation is made up of organophosphorus insecticide or pyrethroid insecticides and Amitraz, be used to prevent and treat agriculture and forestry injurious insects such as cotton bollworm, aphid, mite class, pear sucker, particularly the antagonism insect has the broad spectrum pesticide of control.

Description

The wide-spectrum synergy insecticide that contains Amitraz

The invention belongs to the agricultural insecticidal preparation.

Owing to use organic phosphates and pyrethroid insecticides in a large number year after year, many insects, particularly cotton bollworm had produced serious pesticide resistance in recent years.1992, because this two class medicament commonly used can not be prevented and treated the harm of cotton bollworm and other insect effectively, make the serious underproduction of Cotton in China, be badly in need of the new medicament of exploitation control resistant bollworm.Spy in 1979 opens the binary mixture of having reported among clear 54-84030, the 1982CA1131129 with Amitraz+sumicidin potentiating pesticidal, acaricidal action, but undesirable.

The purpose of this invention is to provide agriculture and forestry injurious insects such as control cotton bollworm, aphid, mite class, pear sucker, particularly the antagonism insect has the broad spectrum pesticide of preventive effect.

Preparation provided by the invention is the binary mixture formed in Amitraz and organophosphorus insecticide phoxim or chlopyrifos or pyrethroid insecticides time or with the ternary mixture of a kind of composition in a kind of and pyrethroid insecticides sumicidin in Amitraz and organophosphorus insecticide phoxim, chlopyrifos, decis, the parathion-methyl, time, the cypermethrin.

In the binary mixture, active ingredient: Amitraz is 5-20%, and 10-15% is better; Chlopyrifos or the phoxim content in preparation is 5-40%, and is better with 10-20%, or the time, and the content in preparation is 0.1-2.0%, and 0.2-1.0% is better.

The active ingredient of ternary mixture: the content of Amitraz in preparation is 5-15%, and is better with 5-10%; A kind of in chlopyrifos, phoxim or the parathion-methyl, the content in preparation is 5-40%, and is better with 10-20%; A kind of in sumicidin, decis, time, the cypermethrin, the content in preparation is 0.5-10%, 1-5% is better.

Be mixed with cream preparation in order to last medicament.Make solvent with in benzene,toluene,xylene, the chloropropylene oxide one or both, select for use neopelex, sodium lignin sulfonate to make emulsifier in the preparation.

Compound method

Each component is added together to scale, fully stir to make and be dissolved into transparent and homogeneous solution and promptly get missible oil.

Amitraz 10%, phoxim 10%, time 0.2%, neopelex 10%, all the other add toluene and are made into 100% cream preparation.

Example 6

Amitraz 10%, chlopyrifos 15%, time 0.4%, neopelex 15%, chloropropylene oxide 5% add toluene and are made into 100% cream preparation.

Example 7

Amitraz 5%, parathion-methyl 27%, sumicidin 8%, sodium lignin sulfonate 15% add dimethylbenzene and are made into 100% cream preparation.

Example 8

Amitraz 5%, parathion-methyl 30%, decis 0.2%, sodium lignin sulfonate 9% add dimethylbenzene and are made into 100% cream preparation.

Example 9

Amitraz 5%, phoxim 20%, decis 0.2%, neopelex 9% add dimethylbenzene and are made into 100% cream preparation.

Preparation as insecticiding effect of the present invention is as follows:

Catch resistant bollworm 3 and make larva July from the cotton field, at the indoor insecticidal test that carries out, cotton leaf is squirted (wet entirely and not dirty) with the normal concentration soup, puts into 500 milliliters beaker.Larva is placed on the paper, after squirting with soup, move on on another paper of doing, inhale too much soup on the debug body, moving into has in the beaker of cotton leaf again, seals the back at indoor feeding with the layer 2-3 gauze, every processing 8-10 head, repeat for three times, handle back investigation in 24 and 48 hours, calculate the average killing rate that repeats for three times and the results are shown in Table 1.

Preparation of the present invention is at indoor cotton bollworm and single agent comparing result such as the table 1 of killing
