In autumn, radishes are produced in large quantities in the field. In production, herbicides can be selected for chemical weeding according to different growth stages. Specifically introduced by the China Pesticide Network Xiaobian:
Before the sowing, the soil can be used, 48% trifluralin emulsifiable concentrate 100~150ml (per mu, the same below), 48% dilamine EC 200ml, 33% weeding emulsifiable concentrate 100~150ml, 50% acetochlor The emulsion is 75~150 ml and sprayed on 50 kg of water. Fluorine is easy to photolysis, volatilization, and reduce the efficacy. Immediately after spraying, it is placed into the soil by 2~3 cm.
