How to weed Atractylodes macrocephala plantings? Please explain the herbicides that can be used on Atractylodes macrocephala and how to apply themAtractylodes macrocephala plantings generally need to control crabgrass, goosegrass, foxtail, barnyardgrass, leptochloa and lovegrass, etc. Commonly used soil-applied pre-emergence herbicides include trifluralin and acetochlor. For application methods, refer to the following:
Generally, 5-10 days before transplanting and before weeds emerge, apply 80-100 ml of 48% trifluralin emulsifiable concentrate per mu, add 40-50 kg of water and spray evenly. Trifluralin volatilizes and photodegrades easily, so shallow tillage should follow spraying immediately to mix the chemical into the 5-7 cm soil layer in time; the field efficacy lasts 2-3 months. Alternatively, 3-5 days before transplanting and before weeds emerge, apply 70-75 ml of 50% acetochlor emulsifiable concentrate per mu, add 40-60 kg of water and spray evenly on the soil surface. According to the situation you describe, before Atractylodes macrocephala emerges, acetochlor can be sprayed for soil pre-emergence treatment. Field moisture greatly affects the soil pre-emergence effect of the above chemicals, and waterlogging after application may cause phytotoxicity to Atractylodes macrocephala. It is recommended to apply on a large scale only after a successful small-area trial.
If grass weeds occur in the field after Atractylodes macrocephala emerges, herbicides such as haloxyfop-R-methyl (high-efficiency gallant) and quizalofop-p-ethyl can be sprayed; they are effective against many grass weeds and safe for Atractylodes macrocephala. When grass weeds in the field have all emerged, apply 40 ml of 5% quizalofop-p-ethyl emulsifiable concentrate or 30-40 ml of high-efficiency gallant per mu, add 30 kg of water and spray.
