Embodiment 1

[0027] The wettable powder is produced by the following weight percentages of each component according to the above process: 3% Zhongshengmycin, 2% Kasugamycin, 5% adjuvant, and 90% carrier. There were two drug controls, drug control 1 containing 3% Zhongshengmycin, 5% adjuvant, and 92% carrier, and drug control 2 containing 2% kasugamycin, 5% adjuvant, and 93% carrier. The blank control is water spray. From October 2008 to June 2009, a control experiment of cucumber bacterial angular spot was carried out in a winter-warm greenhouse in Jitai Town, Shouguang City, Shandong Province. Set up 500 times liquid, 700 times liquid, 900 times liquid of the wettable powder, 700 times liquid of wettable powder of drug control 1, 700 times liquid of wettable powder of drug control 2 and blank control treatment area. Foliar spray, spray once every 7 days, even spray 4 times. Residential Area 30m 2 , repeated 4 times, arranged in random blocks. Wherein the wettable powder 500-fold liqui...

Embodiment 3

[0031]The wettable powder is produced by the following weight percentages of each component according to the above process: 2% Zhongshengmycin, 4% Kasugamycin, 5% adjuvant, and 89% carrier. There were 2 drug controls, drug control 1 containing 2% Zhongshengmycin, 5% adjuvant, and 93% carrier, and drug control 2 containing 4% kasugamycin, 5% adjuvant, and 91% carrier. The blank control is water spray. From September 2008 to July 2009, a control experiment of tomato leaf mold was carried out in a winter-warm greenhouse in Qudi Town, Jiyang County, Shandong Province. Set up 500 times liquid, 700 times liquid, 900 times liquid of the wettable powder, 700 times liquid of wettable powder of drug control 1, 700 times liquid of wettable powder of drug control 2 and blank control treatment area. Foliar spray, once every 7 days, 4 times in a row. Residential Area 25 m 2 , repeated 4 times, arranged in random blocks. Wherein, the wettable powder 500-fold liquid, 700-fold liquid and 9...

Abstract

The invention relates to the technical field of pesticide, and particularly relates to a biological fungicide composition. The biological fungicide composition contains zhongshengrnycin and kasugamycin, wherein the weight ratio of the zhongshengrnycin to the kasugamycin is 1: (0.2-7). The fungicide composition disclosed by the invention is significant in synergized action, high in field efficacy, and wide in bacteriocidal spectrum, and has good control effect on rice blast, fusarium wilt of cucumber, cucumber downy mildew, bacterial angular leaf spot of cucumber, tomato leaf mould, tomato bacterial macula diseases, pumpkin soft rot, watermelon bacterial angular spot, bacterial blotch of watermelon, stuffed watermelon water melon, pepper anthracnose, hot (sweet) pepper bacterial leaf spot, capsicum powdery mildew, pepper grey mould, citrus canker, litchi downy blight, peach tree gummosis, scab of peach and peach shot hole. The control cost is reduced.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a biological bactericide composition, and also relates to the application of the biological bactericide composition. Background technique [0002] In agricultural production practice, plant bacterial diseases and fungal diseases are becoming more and more serious, and often occur in combination. In order to reduce the harm of germs, a large number of fungicides are often used. Due to the long-term application of some fungicides, the bacteria have developed drug resistance and the control effect has decreased, so the dosage has to be increased. Some fungicides have strong specificity so that the control spectrum is narrow, and farmers must use multiple fungicides together. 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.
