Embodiment 1

[0029] L-α-terpineol 5kg, 2-methyl-4 sodium chloride 56kg, sodium lauryl sulfate 3kg, 2-alkylnaphthalenesulfonic acid methane condensate sodium salt 5kg, sodium lignosulfonate 6kg, light calcium carbonate 25kg. According to the requirements of the formula, the raw materials, various additives and fillers are fully mixed, and the wettable powder is obtained after being pulverized by an ultrafine pulverizer.

Embodiment 2

[0031] 10kg of L-α-terpineol, 70kg of atrazine, 5kg of sodium laureth sulfate, 5kg of calcium lignosulfonate, and 10kg of white carbon black. According to the formula ratio, the raw materials, various additives and fillers are fully mixed in the mixer, mixed evenly, and then added to the jet mill to pulverize until the fineness reaches 325 meshes to obtain a wettable powder.

Embodiment 3

[0033] L-α-terpineol 8kg, diuron 80kg, fatty alcohol polyoxyethylene ether sulfonate 2kg, sodium lauryl sulfonate 3kg, fatty alcohol polyoxyethylene ether sulfonate sodium 2kg, attapulgite 5kg. According to the formula ratio, the raw materials, various additives and fillers are fully mixed in the mixer, mixed evenly, and then added to the jet mill to pulverize until the fineness reaches 325 meshes to obtain a wettable powder.

Abstract

A herbicide composition containing l-alpha-terpineol is disclosed. The composition comprises a synergist a and a herbicide active component b, wherein the synergist is the l-alpha-terpineol, and the herbicide active component is one of 2-methyl-4-chlorophenoxyacetic acid, ametryn and diuron or is a mixture prepared from more than one of the 2-methyl-4-chlorophenoxyacetic acid, the ametryn and the diuron. The composition reduces the using amount of herbicides in unit area and improves weeding effects of herbicides for sugarcane fields and safety to sugarcane, thus reducing the herbicide using cost. The composition can be prepared into wettable powder, water dispersible granules, emulsifiable solutions or dispersible oil suspensions, and can be used for control of annual weeds in sugarcane fields.

Description

Technical field [0001] The invention relates to the technical field of pesticides, in particular to a herbicide composition containing L-α-terpineol and a preparation method and application thereof. Background technique [0002] L-α-terpineol (English common name α-(L)-Terpineol) is a chemical product synthesized by the Guangxi Zhuang Autonomous Region Chemical Research Institute (Patent No.: ZL03178548.4, name: L-α-terpineol Preparation method), it has good wetting, adhesion and penetration ability. Guangxi Research Institute of Chemical Industry has conducted a lot of research on its biological activity and application range from 2003 to now. See the published Chinese patents for details, such as: ZL200910114473.3, a fungicide containing difenoconazole and L-α-terpineol Composition and its production method; ZL200910114624.5, a beta-cypermethrin insecticide composition containing a synergist of L-terpineol; ZL201010525128.1, a fungicide composition containing tebuconazole and ...
