Which herbicides can be used to control weeds after garlic emergence
Garlic fields dominated by Gramineae weeds can be sprayed with 50-70 milliliters of 5% refined grass EC and 30 kg of water per mu after garlic emergence and before the 3-leaf stage of weeds. When applying the pesticide, the soil moisture should be better, and the temperature should be above 12 ℃, in order to improve the weeding effect. The mixed fields of Gramineae weeds, Cyperaceae weeds and broad-leaved weeds were sprayed with 40% dry grass EC 100 ml and 40 kg water per mu before the 2-3 leaf stage of garlic and 4 leaf stage of weeds. When applying pesticide, the soil should be moist and avoid high temperature and bright light. Tian Bu is usually used before the seedling of garlic after sowing, but it can also be used in the early stage after seedling, usually in the period of 1-5 true leaves of garlic, 150-200ml of 33% EC per mu and 40-50kg of water to spray evenly on the soil surface.
