Abstract
Five herbicides were evaluated for their weed control efficacy and influence on wheat grain yield for three winter seasons of 1978–79, 1979–80 and 1980–81 at Hawalbagh, Almora. Use of methabenzthiazuron, Metoxuron and Isoproturon caused significant reduction in weed biomass production resulting in increased grain yields. Weed control efficacy was lower in hand weeding, terbutryn and diclofop-methyl treatments. The highest mean grain yield was obtained with isoproturon at 1.00 kg/ha and metoxuron at 1.75 kg/ha (both as post-emergnce) and the lowest in unweeded check followed by hand weeding once. A low degree of phytotoxicity was observed in wheat with terbutryn and diclofopmethyl.

8 of 10 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.
