Seeds are kept in disease-free fields. [Agricultural control] timely sowing and rational close planting. In particular, attention should be paid to controlling the seeding amount of dwarf varieties with strong tillering ability.

[pesticide control] for low humidity, high fertilizer, close planting may occur in the field or the autumn seedling incidence serious area or field, Yu Yue before winter and after returning to green spray 80% carbendazim ultrafine powder 1000 times liquid, each 667m2 dosage 50g ultra low volume or conventional spray. It can also use 36% thiophanate methyl suspension 500 times liquid, 50% benzophenone wettable powder 1500 times liquid, 25% Triazolone emulsifiable 2000 times liquid.
