Effects of 73％ mixed MCPA-Na, ametryn and diuron WP on controlling weeds in sugarcane field
摘要
Abstract
[Objective]The aim of the present study was to determine the efficiency of 73% mixed MCPA-Na, ametryn and diuron WP on controlling weeds in sugarcane field. [Method]Different herbicides (56% MCPA-Na SP 840 a.I.g/ha, 80% ametryn WP 1440 a.I.g/ha, 80% diuron WP 1440 a.I.g/ha) and their different concentrations (876, 1314, 1752 and 2628 a.I.g/ha) were used to control weeds in the sugarcane fields, with water as the controL The controlling effects were investigated after 20 and 40 d of spraying. [Result]The controlling effects of 73% MCPA-Na, ametryn and diuron WP on plant and fresh weight were higher than 90.00% after 20 and 40 d of spraying. The weedicide application @ 876-2628a.I.g/ha resulted in control of most of the monocotyledonous and dicotyledonous weeds in sugarcane field, and showed better controlling effects compared to spraying single dose of 56% MCPA-Na SP, 80% ametryn WP and 80% diuron WP. [Conclusion]73% mixed MCPA-Na, ametryn and diuron WP @ 1314-1752 a.I.g/ha may be recommended to control weeds in sugarcane field.关键词
