How are herbicides used in autumn radish planting?
How do you use herbicides when planting autumn radish? Here is an introduction. For autumn radish weed control, you can refer to the following methods: 1. Pre-sowing soil sterilization: you can choose 48% trifluralin emulsifiable concentrate 100-150 ml (dosage per mu, the same below), 48% dinitramine emulsifiable concentrate 200 ml, 33% pendimethalin emulsifiable concentrate 100-150 ml, 50% acetochlor emulsifiable...
How do you use herbicides when planting autumn radish? Here is an introduction.
For autumn radish weed control, you can refer to the following methods:
I. Pre-sowing soil sterilization: you can choose 48% trifluralin emulsifiable concentrate 100-150 ml (dosage per mu, the same below), 48% dinitramine emulsifiable concentrate 200 ml, 33% pendimethalin emulsifiable concentrate 100-150 ml, and 50% acetochlor emulsifiable concentrate 75-150 ml, each mixed with 50 kg of water for spraying. Trifluralin and similar products are prone to photodegradation and volatilization, which reduces efficacy, so immediately after spraying, rake them into the soil to a depth of 2-3 cm. These herbicides have good control efficacy against barnyardgrass, foxtail, and goosegrass, and have some control efficacy against broadleaf weeds such as amaranth, smartweed, and lambsquarters.
II. Post-sowing pre-emergence soil treatment: you can choose 48% alachlor emulsifiable concentrate 200 ml, 25% oxadiazon emulsifiable concentrate 100 ml, 20% chloramben aqueous solution 700-1000 ml, 50% prometryn wettable powder 60 g plus 48% trifluralin emulsifiable concentrate 100 ml, 72% metolachlor emulsifiable concentrate 100-150 ml, and 50% napropamide wettable powder 100-200 g, each mixed with 50-75 kg of water to spray and wet the soil. These agents can effectively control monocotyledonous weeds and some dicotyledonous weeds.
III. Post-emergence stem and leaf treatment: you can choose 10.8% haloxyfop-R-methyl emulsifiable concentrate 20-35 ml, 10% quizalofop emulsifiable concentrate 50-80 ml, and 35% sethoxydim emulsifiable concentrate 50-80 ml, each mixed with 50 kg of water to spray and kill young weed seedlings. These agents can kill grass family weeds at the 3-5 leaf stage.
