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 dark green spots on the tip of the leaves, and then the lesions gradually extend downward, leaving the leaves bright yellow. Or after the watering condition quickly expanded, the garlic bulbs and garlic bulbs suffered serious loss of output. Chemical control is an important measure to control garlic blight, in order to screen out effective anti-bacterial agents, the author used 50% of Trimoxystrobin dry suspension agent, Amisida 25% azoxystrobin suspension agent, Donning 77% copper sulfate Pharmacodynamic tests were performed on low toxicity broad-spectrum fungicides such as calcium wettable powders.
The test results showed that the use of 25% azoxystrobin suspension per acre 20 grams of azoxystrobin per acre, 50% of Tsui Bei 50% of the ether suspension dry suspension agent and Wanxing 206.7 g / liter ketone flusilazole cream 24 ml 3 treatment The control efficacy was significantly higher than that of the control agent (120g of 70% thiophanate-methyl WP per acre), Amisidae 25% azoxystrobin suspension, and Tribecodin 50% dry suspension The control effect of the agent is more prominent, all over 70%, and the output of garlic sprouts and garlic bulbs is increased by more than 10%. It is recommended to use them in production; Kechuang 3% Zhongshengmycin WP and Doning 77% CuSO4 wettability The control efficacy of powdered two treatments was slightly higher than that of the control drugs, but the yield of garlic sprouts and garlic bulbs did not increase significantly.
It should be noted that the prevention and treatment of garlic leaf blight, in addition to timely chemical control, but also to strengthen field management, rational fertilization irrigation, improve field environmental conditions, improve plant disease resistance.
