Abstract

The present invention relates to pesticide composition of abamectin and bisultap and the preparation of its microemulsion. The abamectin-bisultap composition is compounded with abamectin 0.1-5 wt%, bisultap 10-50 wt%, emulsifier 5-25 wt%, co-solvent 1-15 wt%, synergist 1-10 wt%, stabilizer 1-10 wt% and water for the rest. The abamectin-bisultap composition is prepared in microemulsion, which has lowered toxicity, environment friendship and low cost. The abamectin-bisultap composition has the advantages of high pesticidal activity, high effect, low toxicity, broad pesticidal spectrum, high safety, etc.

Description

1. Technical field [0001] The invention relates to a compound insecticide of avermectin and dimehytap and a preparation method thereof, and belongs to the technical field of insecticides and preparation methods thereof. 2. Background technology [0002] Abamectin is an antibiotic insecticide and acaricide with contact killing, stomach toxicity and strong penetrating effect. Its insecticidal mechanism mainly acts on the gamma-aminobutyric acid (GABA) system of insect neuronal synapses or neuromuscular synapses, causing the neuromembrane to be in a state of inhibition, thereby blocking nerve impulse conduction and causing paralysis, food refusal, and death of insects. Abamectin is effective to common Lepidoptera, Coleoptera pests and pest mites, but its mode of action is single, and long-term continuous use causes many pests (mite) to reduce their sensitivity, and the resistance multiples increase year by year. Pests such as moth, housefly, potato beetle, German cockroach, an...
