Problems solved by technology

[0004] The application of chemical agents is one of the most effective chemical means to control plant pests. It is a good solution to control plant pests with new pesticides without cross-resistance. However, at present, the development of a new pesticide requires the screening of tens of thousands of compounds, which costs 1.2 -150 million US dollars, the development cycle is 5-10 years, it is difficult to catch up with the speed of pest resistance; other methods such as crop layout adjustment, different pesticide rotation, etc., are difficult to achieve obvious effects in the actual operation process effect, the development of new pesticides is expensive and takes a long time

Abstract

The invention discloses a composition for preventing and treating beet armyworms, and belongs to the technical field of pesticides. The composition comprises the following raw materials in parts by weight: 15-20 parts of camellia saponin, 10-15 parts of chlorfenapyr, 8-12 parts of aconitine and 3-7 parts of indoxacarb. The composition compounded according to the specific proportion can effectively prevent and control beet armyworms, has a synergistic effect, is high in safety, reduces the use amount of pesticides, reduces the use cost, has obviously enhanced killing ability on beet armyworms after the components are combined for use, is easy to biodegrade, greatly reduces the residual quantity of pesticides on plants, avoids the harm of biological enrichment to human health through a food chain, reduces the pollution to the environment, delays the generation of drug resistance of diseases and insect pests, and prolongs the service life of the pesticides.

Description

technical field [0001] The invention relates to the technical field of pesticides and insecticides, in particular to a composition for controlling beet armyworm and its preparation method and application. Background technique [0002] Camellia oleifera is a plant of the genus Camellia in the family Theaceae, and is one of the four largest woody edible oil tree species in the world. Camellia oleifera is a unique oil tree species in my country. It has a cultivation history of more than 2,000 years. The existing camellia oleifera forest area in the country is 245,000 hm 2 , mainly distributed in Hunan, Jiangxi, Guangdong, Fujian, Zhejiang and other regions. Camellia oleifera seeds can be deeply processed to obtain products such as camellia oil and camellia saponin. Camellia oleifera saponin is a kind of oleanane-type pentacyclic triterpenoid compound, which is composed of sugar body, aglycone and organic acid. It is distributed in the shell, tea seed and leaf of camellia oleif...
