Embodiment 1

[0054] At room temperature, in parts by weight, take 50 parts of thiophanate-methyl, 1 part of berberine, add 10 parts of sodium dodecylbenzenesulfonate (dispersant), and supplement to 100 parts with bentonite. Pulverize in an ultrafine pulverizer and pass through 200 meshes to obtain 50% thiophanate-methyl wettable powder.

Embodiment 2

[0056] At room temperature, in parts by weight, take 30 parts of thiophanate-methyl, 1 part of berberine, add 10 parts of calcium dodecylbenzenesulfonate (dispersant), and supplement to 100 parts with activated clay. Pulverize in an ultrafine pulverizer and pass through 200 meshes to obtain 30% thiophanate-methyl wettable powder.

Embodiment 3

[0060] At room temperature, in parts by weight, take 60 parts of thiophanate-methyl, add 0.6 parts of berberine, add 10 parts of sodium dodecylbenzenesulfonate, emulsifier 10 parts of phenylethylphenol polyoxyethylene ether . Make up to 100 parts with dimethylformamide. Stir in the reactor at a stirring speed of 200 rpm for 70 minutes and stir to be transparent to obtain a 60% thiophanate-methyl soluble liquid.

Abstract

The invention discloses a thiophanate-methyl compound bactericide and application thereof. The compound bactericide comprises thiophanate-methyl, berberine and the balance of auxiliaries, wherein in percentage by weight, the content of thiophanate-methyl is 30%-60%, and the weight ratio of berberine to thiophanate-methyl is 1: 29-119. The compound bactericide is used for preventing and treating fungal diseases of crops, especially peach brown rot. According to the compound bactericide, thiophanate-methyl serves as a main component, berberine is added to serve as a synergist, the prevention effect of thiophanate-methyl can be remarkably improved, the compound bactericide has the protection and treatment effects, peach brown rot can be effectively prevented and treated, and the compound bactericide is safe to non-target organisms and the environment.

Description

technical field [0001] The invention relates to a thiophanate-methyl compound fungicide and an application thereof, belonging to the fields of agriculture and chemical industry. Background technique [0002] The widespread use of chemical pesticides has played a huge role in ensuring high and stable crop yields. However, the long-term and large-scale irrational use of traditional chemical pesticides has caused the "3R" problem, that is, residue, resistance, and rampant to become more and more serious, which has aroused widespread concern in the society. It is imminent to seek and develop new pesticides that are safe for human health and ecological environment. Since 2015, the Ministry of Agriculture has officially launched the "weight loss and drug reduction" campaign to achieve zero growth in the use of chemical fertilizers and pesticides for crops. Reducing the use of pesticides and improving the control effect is one of the effective ways to solve the zero growth of pes...
