Abstract

Experiments were conducted to assess the emulsion stability revealed that out of four chemicals tested namely, carbendazim, copper oxychloride, NAA, and MgSO4 with diafenthiuron 50 WP at 0.6 g litre-1, none of these products produced creaming matter or sediment, more than 2.0 ml at the top or bottom of the 100 ml cylinder. The results confirmed physical stability of these agro-chemicals with diafenthiuron 50 WP. A field trial was conducted to evaluate the bioefficacy of combinations of diafenthiuron 50 WP with selected Agro-chemicals, as foliar application on 90 days old Bt cotton against sucking pests and foliar diseases. The lowest mean population of aphids (3.28 / 3 leaves), leafhoppers (3.77 3 leaves-1), thrips (1.97 3 leaves-1), whiteflies (0.77 / 3 leaves-1) and mirid bugs (2.00 five squares -1) were recorded in diafenthiuron 50 WP @ 0.6 g + carbendazim 50WP @ 1.0 g with (70.33, 66.81, 89.28, 87.78 and 50.35) high % reduction over control, respectively. Treatments, diafenthiuron in combination with carbendazim (30.01) and copper oxychloride (29.36) were recorded high % disease over control along with the alone fungicidal treatments against Alternaria blight and Bacterial blight, respectively. Diafenthiuron in combination with carbendazim and copper oxychloride were found to be more effective in reducing the sucking pests population and foliar diseases incidence, and safer to the three natural enemies (coccinellids, chrysopids and spiders). All the tested treatments had not caused any phytotoxic symptoms on 90 days old Bt cotton crop.

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.
