Wheat field weeds and wheat seedlings compete for fertilizer, compete for water and win light, which is one of the important factors affecting the normal growth of wheat. During the period when wheat returns to maturity, with the recovery of temperature and improvement of soil moisture, weeds in some wheat fields will rapidly grow and spread. If they are not controlled, they will inevitably affect the normal growth and development of wheat.
Farmers' friends must seize the opportunity to control wheat weeds at the most favorable time for the return of the crop to the green age. According to the types of crops that will be planted after crops, we must scientifically select different herbicides for wheat fields and scientifically control weeds in wheat fields. That is, when weeds reach 50/m2, herbicides should be sprayed immediately for control.
Control methods: 1 cultivating weeding; 2 crops after the corn crop field with 75% tribenuron-methyl per acre dry suspension agent 1-1.5 grams or 10% tribenuronic-methyl WP 10 g water 30-45 kg evenly spray ; 3 After the crop is a field of peanuts or sharp pepper and other broad-leaved crops can be selected 15% Siquisalon 10 grams before the jointing water 30-45 kg evenly spray. 4 control of wild oats and other grassy weeds can be used 6.9% of the horse water agent in the wheat return to green uniform period of spraying.
Finally, remind farmers that friends must spray clean herbicides to avoid phytotoxicity.
