The netizen youth wrote a WeChat on September 12th: The insects on rice, with 1.8% abamectin 1.5% per acre plus Bacillus thuringiensis 60 ml did not kill, what is the reason?
Water clear: Insects on rice should be nocturnal moth pests, and most of them migrate from plants such as field side soy beans to nearby rice plants. These pests generally do not eat rice, and sometimes take small amounts of rice leaves or anthers, etc., generally do not cause major harm, do not need special drug control. Abamectin and Bacillus thuringiensis have strong stomach toxicity and can be used to control pests such as Spodoptera litura, Spodoptera litura and other insect pests. When the larva is smaller, the application effect is better. When the worm age is large, the drug resistance is enhanced, and the drug control effect is enhanced. Will fall. These two drugs have relatively weak contact toxicity. Like the larvae of the insects of the old instar moth, even if the liquid is directly sprayed on the body, it is difficult to quickly kill them. When the medicine is sprayed on the rice plant, the insect does not take the rice plant, and the stomach poisoning effect of the medicine cannot be exerted, and the disinsection effect is naturally not good.
