Embodiment 1

[0054] At room temperature, in parts by weight, take 50 parts of daisenlian and 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% Disenlian wettable powder.

Embodiment 2

[0056] At room temperature, in parts by weight, take 57 parts of daisenlian and 3 parts of berberine, add 10 parts of calcium dodecylbenzenesulfonate (dispersant), and supplement to 100 parts with activated clay. Pulverize in an ultrafine pulverizer, pass through 200 meshes, and obtain 10% Dysenlian wettable powder.

Embodiment 3

[0060] At room temperature, in parts by weight, take 49 parts of Disenlian, add 0.5 parts of berberine, 10 parts of sodium dodecylbenzenesulfonate, and 10 parts of emulsifier phenethylphenol polyoxyethylene ether. Make up to 100 parts with dimethylformamide. Stir in the reaction kettle at a stirring speed of 200 rpm for 70 minutes and stir to be transparent to obtain a 50% soluble liquid of Disenlian.

Abstract

The invention discloses a metiram compound bactericide and application thereof. The compound bactericide comprises metiram, berberine and the balance of auxiliaries, wherein in percentage by weight, the content of metiram is 50%-70%, and the weight ratio of metiram to berberine is (24-99): 1. The compound bactericide is used for preventing and treating fungal diseases of crops, especially peach brown rot. Metiram is used as a main component, berberine is added to serve as a synergist, the prevention effect of metiram can be remarkably improved, and pathogenic bacteria are not likely to generate drug resistance to metiram. The compound bactericide can effectively prevent and treat apple ring rot, and the prevention effect is improved by 18% or above.

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" problem caused by the long-term and large-scale unreasonable use of traditional chemical pesticides, that is, the residue, resistance, and rampantness is becoming more and more serious, which has aroused widespread concern in the society. It is more and more urgent 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 increase the utilization rate of pesticides to over 40% and achieve zero growth in the use of chemical fertilizers and pesticides for crops. Reducing the use of pesticides and improving the ...
