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.

8 of 9 groups shown: named compounds and organisms first, then groups whose results differ (checked claim by claim), then those with positive and negative results, then the smaller groups.
Claims are grouped by organism, treatment and what was measured or targeted. A paper counts as positive when any of its claims in the group is positive.
