Abstract: A field experiment was conducted at Research-cum-Instructional Farm of Raj Mohini Devi College of Agriculture & Research Station, Ambikapur (C.G.) during Kharif -2021, to study the field efficacy of insecticides (which are listed in Table 1) for the management of rice gall midge, Orseolia oryzae. The results revealed that chlorantraniliprole 0.4% GR against the rice gall midge, Orseolia oryzae was found to be most effective treatment and recorded significantly lowest per cent of silver shoot i.e. 3.03% treatment given as main field alone at 25 DAT followed by fipronil 0.3% GR + chlorantraniliprole 0.4% GR i.e. 4.57% SS and carbofuran 3% CG + [cartap hydrochloride 4% + fipronil 0.5% CG] i.e. 4.78% SS whereas both the treatments were given in nursery at one week before transplantation + main field at 25 DAT. Rests of the treatments were moderately effective in terms of minimum damage of gall midge but also superior over untreated control. However, the maximum per cent of gall midge infestations (9.10% SS) was recorded in untreated control.
