The current wheat has entered the heading and flowering stage, which is a key period for the formation of yield. Due to the recent rains, the incidence of wheat scab will be aggravated, and the aphids are also moving to the wheat ears. At present, it is a key period for the prevention and control of wheat powdery mildew, scab and sorghum. Therefore, farmers are reminded to do a good job in the management of field crops, to prevent pests and diseases, and to ensure stable and high yield of wheat this year.
Powdery mildew: 15% triadimefon WP 60-70 g or 20% triadimefon emulsifiable concentrate 50-60 ml per acre at the beginning of the disease, evenly sprayed with water 30-45 kg.
Scab: choose 25% tebuconazole (also known as Likexiu) EC 2500 times solution, 50% prochloraz manganese salt, 50% prochloraz manganese complex (also known as Shi Baogong)
1000~2000 times liquid, 25% cymene suspension agent 100~200g per acre or use of their compounding agent, such as 63.5% prochloraz manganese salt? carbendazim wettable powder 22~24g per mu.
Aphids: Choose 10% imidacloprid or 3% acetamiprid.
In the prevention and control of pests and diseases, we must master the method of medication. When spraying, we should focus on the uniform spray of wheat ears. If it rains after spraying, it will be sprayed after the rain.
