In recent years, garlic leaf blight has been common in Shandong and other places. It usually begins in early April. The diseased plants first appear in the leaf tip with dark green spots. Afterwards, the lesions gradually extend downwards, making the leaves fresh yellow. Or after the watering, the condition spreads rapidly, and the yield of garlic and garlic is seriously lost. Chemical control is an important measure to control garlic leaf blight. In order to screen out high-efficiency control agents, the author chooses Tsuibei 50% ether fungicide dry suspension agent, Amicida 25% azoxystrobin suspension, and Doning 77% copper sulfate. Low-toxic broad-spectrum fungicides such as calcium wettable powders are tested for efficacy.
The test results showed that 20 grams of ampicda 25% azoxystrobin suspension, 10 grams of Tribes 50% ether fungus dry suspension and 206.7 grams of ketone fluorosilicone emulsifiable concentrate 24 ml per acre The treatment effect of the treatment was significantly higher than that of the control agent (120 g of thiophanate-methyl WP WP per acre), and the ampicillin 25% azoxystrobin suspension and the emerald 50% ether oxystrobin The anti-overloading agent has more prominent effects, all of which are above 70%, and the production of garlic and garlic is increased by more than 10%. It is recommended to be used in production; Kecocon 3% zhongshengmycin wettable powder and tannin 77% copper sulfate can be used. The control effect of the two treatments of wet powder was slightly higher than that of the control agent, but the increase in the yield of garlic and garlic was not obvious.
It should be noted that in order to control garlic leaf blight, in addition to timely drug control, it is necessary to strengthen field management, rational fertilization, improve field environmental conditions, and improve plant disease resistance.
