Embodiment 1

[0028] The wettable powder is produced by the following weight percentages of each component according to the above process: Zhongshengmycin 2%, pyrimethanil 20%, auxiliary agent 8%, carrier 70%. There were 2 drug controls, drug control 1 containing 2% Zhongshengmycin, 8% auxiliary agent, and 90% carrier, and drug control 2 containing 20% ​​pyrimethanil, 8% auxiliary agent, and 72% carrier. The blank control is water spray. From October 2009 to June 20010, a control experiment of tomato gray mold was carried out in a winter-warm greenhouse in Cuizhai Town, Jiyang County, Shandong Province. 1000 times liquid, 1500 times liquid, 2000 times liquid of the wettable powder, 1000 times liquid of wettable powder of drug control 1, 1000 times liquid of wettable powder of drug control 2 and blank control treatment area were set. Foliar spray, spray once every 7 days, even spray 3 times. Residential Area 25m 2 , repeated 4 times, arranged in random blocks. Among them, the field contr...

Embodiment 2

[0030] The wettable powder is produced by the following weight percentages of each component according to the above process: Zhongshengmycin 3%, pyrimethanil 12%, auxiliary agent 6%, carrier 79%. There were 2 drug controls, drug control 1 containing 3% Zhongshengmycin, 6% auxiliary agent, and 91% carrier, and drug control 2 containing 12% pyrimethanil, 6% auxiliary agent, and 82% carrier. The blank control is water spray. From October 2009 to June 2010, the experiment on the control of bacterial angular spot of cucumber was carried out in the winter-warm greenhouse in Huangcheng Town, Linzi City, Shandong Province. 1000 times liquid, 1500 times liquid, 2000 times liquid of the wettable powder, 1000 times liquid of wettable powder of drug control 1, 1000 times liquid of wettable powder of drug control 2 and blank control treatment area were set. Foliar spray, spray once every 7 days, even spray 3 times. Residential Area 30 m 2 , repeated 4 times, arranged in random blocks. ...

Embodiment 3

[0032] The wettable powder is produced by the following weight percentages of each component according to the above process: Zhongshengmycin 0.8%, pyrimethanil 25%, auxiliary agent 8%, carrier 66.2%. There were 2 drug controls, drug control 1 containing 0.8% Zhongshengmycin, 8% auxiliary agent, and 91.2% carrier, and drug control 2 containing 25% pyrimethanil, 8% auxiliary agent, and 67% carrier. The blank control is water spray. From September 2009 to July 2010, a control experiment of tomato early blight was carried out in a winter-warm greenhouse in Qudi Town, Jiyang County, Shandong Province. 1000 times liquid, 1500 times liquid, 2000 times liquid of the wettable powder, 1000 times liquid of wettable powder of drug control 1, 1000 times liquid of wettable powder of drug control 2 and blank control treatment area were set. Foliar spray, spray once every 7 days, even spray 4 times. Residential Area 25 m 2, repeated 4 times, arranged in random blocks. Among them, the fiel...

Abstract

The invention relates to the technical field of pesticides and particularly relates to a farm-oriented bactericide. The farm-oriented bactericide contains Zhongshengmycin and pyrimethanil. The weight ratio of the Zhongshengmycin to the pyrimethanil is 1: (4-50). The farm-oriented bactericide is applied to preventing and treating plant fungal diseases and bacterial diseases. The synergistic effect is obvious and the field efficacy is high; a bacteriocidal spectrum is obviously enlarged and the prevention effects on cucumber gray mould, cucumber bacterial angular leaf spot, tomato grey mould, tomato leaf mould, early blight of tomato, tomato bacterial leaf spot, tomato mail head spot, tomato stem rot, pumpkin gray mould, pumpkin soft rot, cauliflower gray mould, garlic gray mould, chive gray mould, strawberry gray mould, grape gray mould, chili gray mould, cowpea gray mould, apple scab, apple altermaria leaf spot, pear scab, pear black spot and tobacco brown spot are very good; the prevention cost is reduced and the manpower of farmers is saved; and the technical threshold is low and the production process is simple.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to an agricultural fungicide. Background technique [0002] In agricultural production practice, plant bacterial diseases and fungal diseases often occur together. Chemical control is an important way to reduce disease loss and increase agricultural output. Some fungicides have a narrow control spectrum, and farmers must use multiple fungicides together. However, long-term and large-scale application of chemical fungicides will cause the bacteria to develop resistance to it, so that the control effect will decline rapidly, and the dosage will have to be increased. The abuse of chemical fungicides has caused serious environmental pollution and food safety problems. The development of new biological fungicides is an important way to solve the above dilemma. [0003] Zhongshengmycin (zhongshengmycin) belongs to N-glycosides and is a broad-spectrum agricultural bactericidal antib...
