Studies were conducted to evaluate the efficacy of seven insecticides, i.e., Fyfenon 57EC, Curacron 500EC, Thiodan 35EC, Lorsban 40EC, Regent 5%SC, Ematac 1.9EC and Confidor 20SC in plum orchard for reducing the gummosis damage induced by Peach flat-headed borer. The mean density of new gum points /m2 on bark surface area treated with Confidor 20SC @ (30 ml/ 10 L) was significantly lower (7.55) followed by Thiodan 35EC (7.80) applied @ (50 ml/ 10 L), as compared to the untreated control (40.49). ). In trees that received two applications, the mean density of new gum points/m2 of bark surface area were significantly lower (11.24) as compared to the trees that were sprayed once (15.86). Highest percent reduction in gummosis was offered by Confidor 20SC (81.4%) followed by Thiodan 35EC (80.7%), whereas the lowest by Curacron 500EC (70.4%). It is suggested that two sprays of Confidor 20SC (imidacloprid) can successfully reduce gummosis damage caused by this pest.
