Abstract

The invention discloses pyrifluquinazon and clothianidin pesticide composition. Effective components of the composition comprise a first active component pyrifluquinazon, a second active component clothianidin and an acceptable dilute or carrier for a pesticide, wherein a weight ratio of the first active component to the second active component is 20:1-1:20, and the best weight ratio of the first active component to the second active component is 5:15-20:1. Agriculturally allowable wettable powder, suspending agents or water dispersible granules can be prepared from the composition. The composition comprises reasonable components, has a better control effect on tomato bemisia tabaci or tea tree empoasca flavescens matumura as well as low application cost, long persistence, small preparation residues and good safety and is non-pollution for crops, and besides, compared with a conventional single agent, the composition can effectively slow down resistance and meets the safety requirements of pesticide preparations.

Description

technical field [0001] The invention relates to a pesticide composition, in particular to a pesticide composition which uses pyridine, quinazoline and clothianidin as active ingredients for preventing and controlling agricultural pests, and is especially suitable for preventing and controlling tomato bemisia tabaci and tea leafhopper . Background technique [0002] Pyridine quinazoline, the common name in English is Pyrifluquinazon. It is a new type of quinazoline insecticide. The mechanism of action is to prevent pests from eating until the pests slowly starve to death. Rib-suction mouthparts such as horses. It can significantly reduce the spread of virus vectors, the compound can completely penetrate the leaf surface, and can effectively prevent and control the pests that inhabit and hide under the leaf surface. It is safe for non-target organisms, has special effects on pests that are resistant to traditional pesticides such as neonicotinoid pesticides, pyrethroids, an...
