Abstract

The invention discloses a composition for controlling wheat mites and a preparation method thereof. The composition is prepared from, by weight, 25-35 parts of butoxycarboxim, 15-25 parts of tigloidine, 135-155 parts of propylene glycol, 425-445 parts of water and 7-9 parts of synergist trimethylolpropane ester and n-caprylic acid, wherein the weight ratio of trimethylolpropane ester to n-caprylic acid is (6-8):1. The composition can control wheat mites and be developed into pesticides for controlling wheat mites; the control effect is related to the weight ratio of synergist trimethylolpropane ester to n-caprylic acid in the raw materials, and the best control effect can be achieved when the weight ratio of trimethylolpropane ester to n-caprylic acid is (6-8):1.

Description

technical field [0001] The invention belongs to the field of pesticides, and in particular relates to a composition for controlling wheat spiders and a preparation method thereof. Background technique [0002] Wheat spiders belong to the class Arachnida, order Acarina. There are mainly two types of mites that harm wheat in China: the wheat round spider and the wheat long-legged spider. The former belongs to the genus Eupedidae. The wheat orb spider occurs in the winter wheat area between 37 degrees and 29 degrees north latitude; the wheat long-legged spider is distributed in the north, mainly in the wheat production area between 34 and 43 degrees north latitude. In most parts of Anhui Province, it is the wheat orb spider that is harmful. In northern Anhui, such as Dangshan, two kinds of wheat spiders are mixed. The two kinds of wheat spiders mainly harm wheat, while barley suffers lightly. Wheat spiders suck leaf sap during wheat seedlings. There are many small white sp...
