Embodiment 1

[0039]

[0040] Preparation:

[0041] The emamectin, pyrethroid compound, soybean oil, toluene diisocyanate, xylene and emulsifier are homogeneously mixed to prepare an organic phase. Dissolve 1,4-butanediol, siloxane, and sucrose in water to prepare an aqueous phase. Under rapid stirring, pour the organic phase into the water phase, then add diethylene ethylene triamine, and stir while adding, until the average size of oil droplets is between 3 and 5 microns. The temperature of the obtained microcapsule suspension was raised to 50° C. and kept for 3 hours. Cool to room temperature, add pectin, and adjust the pH value to 7.0 with 30% ammonia water and concentrated sulfuric acid to obtain microcapsules.

Embodiment 2-6

[0042] Embodiment 2-6 cockroach killing microcapsules

[0043] Compared with Example 1, the only difference is that the composition and dosage of each auxiliary agent are different, see Table 1 for details:

[0044]

[0045]

Embodiment 7

[0047]

[0048]

[0049] Preparation:

[0050] Homogenously mix emamectin, pyrethroid compound, sesame oil, toluene diisocyanate, xylene and emulsifier to prepare an organic phase. The aqueous phase is prepared by dissolving glycerol, siloxane, and fructose in water. Under rapid stirring, pour the organic phase into the water phase, then add diethylene ethylene triamine, and stir while adding, until the average size of oil droplets is between 3 and 5 microns. The temperature of the obtained microcapsule suspension was raised to 50° C. and kept for 3 hours. Cool to room temperature, add pectin, and adjust the pH value to 7.0 with 30% ammonia water and concentrated sulfuric acid to obtain cockroach-killing microcapsules.

Abstract

The invention relates to an insecticidal composition containing methylamino abamectin and pyrethroid compounds. The insecticidal composition is prepared into a microcapsule or a gel bait from a raw material comprising the following components in parts by weight: 1 part of emamectin benzoate, 1-40 parts of pyrethroid, 1-5 parts of vegetable oil, 2-5 parts of oil-phase monomers, 5-20 parts of organic solvents, 5-20 parts of water-phase monomers, 5-12 parts of emulsifying agents, 5-20 parts of attractants, 1-3 parts of auxiliary agents, 0.5-3 parts of defoaming agents, 0.2-30 parts of thickening agents and 18-55 parts of water. The obtained insecticidal composition has the advantages of long persistence on cockroaches and outstanding chain cockroach killing effect.

Description

technical field [0001] The invention relates to an insecticidal composition, in particular to an insecticidal composition containing emamectin and a pyrethroid compound. Background technique [0002] The loss of crop yield due to pests and diseases of crops is immeasurable. Therefore, it is necessary to apply a large amount of pesticides for pest control every year to recover the loss of crop yield. In recent years, pests have become more and more harmful to crops such as rice, fruit trees, vegetables, flowers and various economic crops, and due to the abuse of pesticides, pests have become more and more resistant to pesticides, resulting in pest control effects decrease year by year. Therefore, there is still a need for pesticide varieties with better pest control effects. [0003] Emamectin and its salts are known broad-spectrum, low-toxic insecticides and acaricides, which can effectively control aphids, mites, diamondback moth, cabbage caterpillar, and Liriomyza sativa...
