An attempt has been made to work out the comparative bio-efficacy of different novel acaricides (abamectin, fenazaquin, diafenthiuron, propergite) belonging to different groups (IRAC) and primary target site of mites against the obnoxious mite T. urticae of marigold. The reflection of damage in marigold by the mite vis-a-vis their ecological preferences have also been worked out.
