High Effective Insecticide Spirotetramat 22.4% SC CAS NO 203313-25-1
Spirotetramat is a quaternary keto acid compound. Spirotetramat has unique action characteristics and is one of the modern insecticides with two-way systemic conductivity. The compound can move up and down in the entire plant body, reaching the leaf surface and bark, thereby preventing pests such as the inner leaves of lettuce and cabbage and fruit bark. This unique systemic performance can protect new stems, leaves and roots and prevent the growth of pest eggs and larvae. Another feature is that it lasts for a long time, can provide effective control for up to 8 weeks, broad-spectrum, can control various piercing-sucking pests, and has no cross-resistance with conventional insecticides.
