Effect of Fenoxaprop-P-ethyl Controlling Gramieous Weeds in Wheat Field

[Objective] The aim of this study was to search for economical, safe and highly-efficient herbicide to control gramineous weeds in wheat field. [Method] Through spraying 10% Fenoxaprop-P-ethyl EW, organic silicone additive and 6.9% puma super EW in wheat field, the control effect of different herbicides on gramineous weeds was compared. [Result] All the herbicides were safe to the growth of the wheat. 10% Fenoxaprop-P-ethyl EW and 6.9% puma super EW had better control effect on gramincous weeds. Moreover, the cost of domestic Fenoxaprop-P-ethyl was low- er than imported puma super. [Conclu- sion] 10% Fenoxaprop-P-ethyl EW can be used to control gramineous weeds in wheat field, and the optimal spraying time is the 2-4 leaf stage of gramineous weeds.
