Abstract:
Applicability and weed control effects of different herbicide in Astragalus sinicus fieldAbstract: Field experiments were conducted to determine the applicability and their control effects of five kinds of herbicide on broadleaf weeds in Astragalus sinicus field. The results indicated that applications of 56% MCPA-Na WP (900ml?ha-1) and 48% Bentazone (2700ml?ha-1) in March showed no damage to A. sinicus and efficiently controlled broadleaf weeds in A. sinicus field. After the application of above two herbicides, the control efficacies based on plant number and fresh weight for broadleaf weeds were more than 70%. Compared to the check treatment, the fresh weight of A. sinicus was increased 47.92% and 60.42% respectively and the seed yield of Astragalus sinicus was increased 21.72% and 31.67% respectively.
