Abstract

The invention discloses a mite-killing composition. The mite-killing composition contains two active ingredients, namely, C20H22Cl2O5 and etoxazole. The mite-killing composition may further comprise a carrier and auxiliary agents and may be prepared to form missible oil, a suspending agent, a micron emulsion, an emulsion in water, a wettable powder, a soluble powder, a granule or a capsule. The mite-killing composition provided by the invention has remarkable synergism, can delay resistance caused by usage of a single medicament and exerts a high protection effects on mites on fruit trees, cotton and tea trees.

Description

【Technical field】 [0001] The invention relates to an agricultural acaricidal composition, in particular to an acaricidal composition containing spirobudiclofen and etoxazole and application thereof. 【Background technique】 [0002] Agricultural pest mites are one of the most difficult pests to control due to their small size, rapid reproduction, strong adaptability, and easy resistance. Pest mites are important organisms of fruit trees, vegetables, and agricultural and forestry crops. They mainly harm leaves, but also young shoots, flower buds and fruits. A sharp increase in the number of insect populations often causes plant defoliation, growth inhibition or even death. The crops in the affected area are often slightly shorter, and the quality and yield are obviously reduced. Long-term use of a single acaricide species can easily lead to rapid development of resistance, so it is of great significance to develop and prepare acaricide compositions to prolong the service life...
