| Abstract: | Using the method of contrast trial, the effect on controlling S. planiculmis Fr. Schmidt weeds applying different MCPA-Na NP dosage in rice field was researched. The result indicated that the controlling efficacy reach to 97. 2% and the efficacy on restraining fresh weight of remaine weeds was 99. 2% , applying 56% MCPA-Na NP 2. 25 kg/hm2 in peak tillering stage with the method of spraying herbicide on stem, which didn t affect rice growth. |
