| Abstract: | In order to better control the weeds on gravel-mulched field of watermelon,a field plot experiment concerning the effect of metolachlor 960 g/L EC on control of the weeds and its safety to watermelon on gravel-mulched field was carried out. The results showed that the control effects of metolachlor 960 g/L EC with a dosage of 756 g a.i./hm^2- 936 g a.i./hm^2 adding water 750 L/hm^2 to spray the soil on the annual weeds was 83.07%- 90.73% and the watermelon grew normally in all testing plots. The metolaehlor 960 g/L EC has been proved having high safety,good control effects and a long period of effectiveness. |
