What herbicides are suitable for autumn radish fields
For pre-sowing soil sterilization, you can choose 48% trifluralin emulsifiable concentrate 100-150 ml (dosage per mu, the same below), 48% butralin emulsifiable concentrate 200 ml, 33% pendimethalin emulsifiable concentrate 100-150 ml, 50% acetochlor emulsifiable concentrate 75-150 ml, and spray each mixed with 50 kg of water. Trifluralin and similar products are prone to photodegradation and volatilization, which reduce efficacy, so immediately after spraying...
For pre-sowing soil sterilization, you can choose 48% trifluralin emulsifiable concentrate 100-150 ml (dosage per mu, the same below), 48% butralin emulsifiable concentrate 200 ml, 33% pendimethalin emulsifiable concentrate 100-150 ml, 50% acetochlor emulsifiable concentrate 75-150 ml, and spray each mixed with 50 kg of water. Trifluralin and similar products are prone to photodegradation and volatilization, which reduce efficacy, so immediately after spraying use a toothed rake to incorporate them into the soil at 2-3 cm. These herbicides have good control efficacy against barnyardgrass, foxtail, and goosegrass, and have certain efficacy against broadleaf weeds such as amaranth, smartweed, and lambsquarters.
For pre-emergence soil treatment after sowing, 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, 50% napropamide wettable powder 100-200 g, and spray each mixed with 50-75 kg of water to moisten the soil. These agents can effectively control monocotyledonous weeds and some dicotyledonous weeds.
For 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, 35% sethoxydim emulsifiable concentrate 50-80 ml, and spray each mixed with 50 kg of water to kill young weed seedlings. These agents can kill grass weeds at the 3-5 leaf stage.
