How should herbicides be used for planting autumn radishes? What are the application methods?
When planting radishes in autumn, the amount of weeds in the field is relatively large, so in production, herbicides can be selected according to actual conditions for chemical weed control.
For pre-sowing soil treatment, you can choose 48% trifluralin emulsifiable concentrate 100-150 ml (dosage per mu, 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 after spraying, immediately 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 a certain control efficacy against broadleaf weeds such as amaranth, smartweed, and lambsquarters.
For soil treatment after sowing and before emergence, 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 the soil until wet. 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, and 35% fluazifop-p-butyl 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.
