Embodiment 1

[0023] Embodiment 1: first with disproportionated rosin potassium soap and copper sulfate, organic solvent, water, react under 60-80 ℃ of temperature conditions and make rosinic acid copper solution; In 860kg rosinic acid copper solution, add the fine nail cream of about 60kg Ling crude oil (content is more than 90%), after mixing uniformly, add 80kg of emulsifier (calcium alkylbenzene sulfonate, castor oil polyoxyethylene ether, fatty alcohol polyoxyethylene ether, Tween 60 or one of various More than one species), after fully stirring, the bactericidal composition of 1000kg of metalaxyl-fine and copper rosinate of the present invention was obtained.

Embodiment 2

[0024] Embodiment 2: first with disproportionated rosin potassium soap and copper sulfate, organic solvent, water, the rosinic acid copper solution that reacts under 60-80 ℃ of temperature conditions; In 810kg rosinic acid copper solution, add about 40kg of rosinic acid copper solution Frostling crude oil (content more than 90%), after mixing, add 130kg of emulsifier, then add 20kg synergist azone, after fully stirring, promptly make 1000kg of refined metalaxyl and rosinic acid of the present invention Antiseptic composition of copper.

Abstract

The bactericide composition for crops consists of s-metalaxyl 0.5-25 wt%, copper rosinate 5-30 wt%, emulsifier 5-20 wt%, and organic solvent 30-50 wt%. The emulsifier is one or several of calcium alkyl benzenesulfonate, caster oil polyoxyethylene ether, fatty alcohol polyoxyethylene ether and Tween-60; and the organic solvent is one or several of xylene, superior oil and heavy oil. Into the components, azone in 0.1-5 wt% may be also added. The bactericide composition of the present invention has both prevention and treatment effects, broad bactericidal spectrum, high bactericidal effect, delayed resistance and raised environment and user safety.

Description

technical field [0001] The invention is a fungicidal composition for crops. Background technique [0002] As a fungicide with significant protective, therapeutic and eradicating effects, metalaxyl is widely used in the control of crop diseases. As a broad-spectrum, protective fungicide, copper rosinate is also widely used in the control of crop diseases. Due to the common use of a certain fungicide in recent years, the emergence of drug resistance has resulted in a decline in the control effect of the fungicide. Therefore, it is an urgent problem to develop a pesticide preparation with high efficiency and broad spectrum that can delay the generation of drug resistance. Contents of the invention [0003] The technical problem to be solved by the present invention is to propose a fungicidal composition for crops, which has the characteristics of synergistic effect, broad spectrum and ability to delay the occurrence of drug resistance, aiming at the defects existing in the ...
