Abstract
The invention discloses a pesticide composite containing spirotetramat and belongs to the technical field of pest chemical prevention. The pesticide composite comprises active ingredients, namely A spirotetramat and B dinotefuran, wherein the weight ratio of A and B is 1:20-20:1. Besides the active ingredients, the pesticide composite further comprises auxiliaries and packing. The active ingredients, namely A and B occupy 15%-50% of the total weight of pesticides, the auxiliaries occupy 20%-30% of the total weight of the pesticides, and the rest is the packing. The pesticide composite can be prepared into wettable powder, suspending agents and the like. The pesticide composition containing the spirotetramat has good prevention effects on rice planthoppers, aphids, vegetable bemisia tabaci and the like. Compared with a conventional agent for preventing the rice planthoppers, the pesticide composite can reduce a dosage, reduce environmental pollution and residues of agricultural products, can delay drug resistance on a single pesticide of the rice planthoppers, and has the advantage of a long lasting period. Compared with the single pesticide, the pesticide composite can reduce cost.
Description
technical field [0001] The invention belongs to the technical field of pest chemical control and relates to an insecticide composition containing spirotetramat. Background technique [0002] Rice planthopper is one of the main pests in the rice growth period. It reproduces quickly and is very harmful. In mild cases, rice planthoppers cause abnormal heading and 1,000-grain weight. Leaf blight, black-streaked dwarf. For a long time, the control of rice planthoppers has mainly relied on imidacloprid, buprofezin, organophosphorus and their compounding agents. The use of highly toxic organophosphorus pesticides has been banned. Due to long-term single and continuous use, brown planthoppers and brown planthoppers have had significant effects on imidacloprid. The control effect of buprofezin decreased sharply, and the control effect of buprofezin on rice planthopper began to decline, which brought serious losses to rice production. In recent years, the emergence of newly develop...
