Abstract

A field investigation was carried out to evaluate the effect of herbicides and their mixtures on weeds in wheat (Triticum aestivum L.) cv. PBW-343. Minimum weed density per m2 and weed dry weight (5.13 and 17.31g) was recorded with sulfosulfuron at 25g ha−1 followed by clodinofop at 60g + metsulfuron methyl at 4g ha−1 (5.19 and 18.45g), metribuzin at 200gha−1(5.85 and 25.98g), pendimethalin at 1000g fb 2,4-Dat400g ha−1 (6.49 and 31.73g) and hand weeding twice(7.01 and 35g), respectively. Also, maximum weed control efficiency was recorded under sulfosulfuron at 25g ha−1 (83.85%) followed by clodinofop at 60g + metsulfuron methyl at 4g ha−1 (83.17%) and metribuzin at 200g ha−1 (75.85%), respectively. All the weed control treatments recorded significantly higher harvest index than the weedy check (40.24). Among various herbicidal treatments, application of clodinofop at 60g + metsulfuron methyl at 4g ha−1 recorded highest harvest index (41.91) followed by sulfosulfuron at 25 gha−1 (41.83) and pendimethalin at 1000g fb2,4-Dat 400gha−1 (41.25) respectively. The harvest index recorded under clodinofop at 60g + metsulfuron methyl at 4g ha−1 and sulfosulfuron at 25 g ha−1 was significantly at par with weed free (42.06).

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.
