Abstract

The invention relates to a biological pesticide for preventing and controlling heliothis armigera hubner. The pesticide is harmless to people and livestock, and has the characteristics of high efficiency, low toxicity and long duration of efficacy as well as a certain yield increasing effect, and pesticide hazards to crops, pesticide residues and environmental pollution are avoided. The biological pesticide for preventing and controlling heliothis armigera hubner is characterized by comprising the following extract and auxiliaries in parts by weight: 150 to 200 parts of matrine, 100 to 150 parts of nicotine, 150 to 200 parts of cynanchum komarovii, 50 to 70 parts of tripterygium wilfordii, 80 to 120 parts of Chinese honeylocust fruits, 50 to 80 parts of hairyvein agrimony, 40 to 60 parts of radix euphorbiae lantu, 80 to 120 parts of melia azedarach fruits, 40 to 60 parts of cortex meliae, 80 to 100 parts of pyrethrum flowers, 50 to 80 parts of radix stemonae, 50 to 80 parts of geranium wilfordii and 60 to 90 parts of euphorbic acid.

Description

technical field [0001] The invention relates to the technical field of biological pesticides, in particular to a biological pesticide for controlling cotton bollworm. Background technique [0002] Cotton bollworm (Heliothis armigera Hübner) belongs to Lepidoptera Noctuidae. It has a wide range of hosts and strong reproductive ability. It is one of the main pests that damage cotton and other crops in Asia, Oceania, Africa and Europe, and is a worldwide crop pest. . Since the 1990s, the annual frequency of cotton bollworm outbreaks in major cotton producing areas such as the Yellow River, Yangtze River, Liaohe River and Xinjiang has increased significantly, resulting in a cotton yield reduction rate of 35-50%, and some fields in some areas even have no harvest. [0003] At present, chemical pesticides are still used as the main means to control cotton bollworms due to their quick-acting and stable advantages, but the "three Rs" produced during the use of chemical pesticides, ...
