Embodiment 1

[0055] At room temperature, in parts by weight, take 50 parts of Dysenlink and 1 part of berberine, add 10 parts of sodium dodecylbenzenesulfonate (dispersing agent), and supplement to 100 parts with bentonite. Pulverize in an ultra-fine pulverizer, pass 200 mesh, and obtain 50% Desenlian wettable powder.

Embodiment 2

[0057] At room temperature, in parts by weight, take 57 parts of Dysenlink and 3 parts of berberine, add 10 parts of calcium dodecylbenzenesulfonate (dispersing agent), and make up to 100 parts with activated clay. Pulverize in an ultra-fine pulverizer to obtain 57% Desenlian WP.

Embodiment 3

[0061] At room temperature, in parts by weight, take 49 parts of Dysenlink, add 0.5 part of berberine, 10 parts of sodium dodecylbenzenesulfonate, and 10 parts of phenylethylphenol polyoxyethylene ether as an emulsifier. Make up to 100 servings with dimethylformamide. In the reaction kettle, stirring was carried out at a stirring speed of 200 rev / min for 70 minutes, and stirring was transparent to obtain a 49% Dysenlian soluble liquid.

Abstract

The invention discloses a disenlian compound fungicide and an application thereof. The compound fungicide includes dysenlian and berberine, and the rest are auxiliary agents; wherein, in terms of weight percentage, the content of dysenlian is 50%-70%, and the weight ratio of dysenlian to berberine is 24%. ‑99:1. The compound fungicide is used for preventing and controlling fungal diseases of crops, especially peach brown rot. The compound fungicide of the present invention uses daisenlian as a main component, and adding berberine as a synergist can significantly improve the control effect of daisenlian, and bacteria are not easy to develop drug resistance to it. The compound fungicide can effectively prevent and control apple ringworm, and the control effect is increased by more than 18%.

Description

technical field [0001] The invention relates to a daisenlian 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 "3R" problems caused by the long-term and unreasonable use of traditional chemical pesticides, that is, residues, resistance, and rampant re-emergence are becoming more and more serious, which has caused widespread concern in the society. There is an increasingly urgent need to seek and develop new pesticides that are safe for human health and ecological environment. Beginning in 2015, the Ministry of Agriculture officially launched the "Slimming and Drug Reduction" campaign to make the utilization rate of pesticides more than 40% and achieve zero growth in the use of fertilizers and pesticides in crops. Reducing the amount of pesticides used and improving the...
