Abstract

The invention discloses an azadirachtin and cyfluthrin composite for preventive treatment on potato beetles, which is composed of the following components by weight percentages: 60%-90% of cyfluthrin and 10%-40% of azadirachtin. The composite provided by the invention has the function of effectively killing the potato beetles.

Description

technical field [0001] The invention relates to a pesticide composition of azadirachtin and cyfluthrin for controlling potato beetles. Background technique [0002] The potato beetle Leptinotarsa ​​decemlineata (Say) is an important and devastating quarantine pest worldwide. The worm originated in North America, and then spread to France, Germany, Spain, Italy, Eastern Europe, and some countries in South America, and caused serious harm in these countries or regions. Potato beetle has been introduced into Tacheng, Yili, Urumqi counties and other places in Xinjiang from the port of Kazakhstan in the 1990s, and has been listed as a class of harmful organisms in the "List of Dangerous Venereal Diseases, Insects, and Weeds for Imported Plant Quarantine". Spread to most of Xinjiang, covering an area of ​​297,200 km 2 , and its hazards are rapidly increasing. At present, the control of potato beetle at home and abroad is mainly controlled by chemical pesticides. However, accor...
