Abstract

The invention relates to an insecticidal composition containing spirotetramat. The effective components of the composition are abamectin B2a and spirotetramat which are mixed in a weight ratio of (1-50) to (1-50). The total percentage of the effective components in the insecticidal composition is 1-80% and the rest is auxiliary elements which are allowed to use and can be accepted in pesticide. The composition can be prepared into wettable powder, suspensions, microemulsions, emulsions in water and water dispersible granules. The composition provided by the invention is wide in action field, high in insecticidal efficiency, small in dosage, high in control effect, small in residue, long in lasting period and favorable for environmental protection.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to an insecticidal composition containing spirotetramat. Background technique [0002] Abamectin is a macrolide disaccharide compound with contact killing and stomach poisoning effects, and has strong penetrating power. Abamectin is a 16-membered macrolide insecticidal natural product produced by Streptomyces fermentation. A large component of the homologue B1 and its derivatives have been commercialized, but at the same time, they have also derived pesticide resistance Due to the large amount of pesticide used by farmers, the resistance of crop pests is stronger, so the control effect of single-dose pesticide products of Abamectin B1 is getting lower and lower. B2a, another major component of avermectin homologues, has a higher toxicity activity to certain arthropods and non-digestive nematodes than B1, especially to corn rootworms and yellow powder beetles. The toxicity of B2a...
