Evaluation of eco-friendly treatments against bollworms

An experiment was conducted at Agricultural Research Station, Sriganganagar to study the effect of some eco friendly treatments on bollworms. The pooled data of two years revealed that the minimum boll and locule damage was recorded in the treatment of triazophos followed by thiocloprid (Calypso) and Econeem. The maximum boll damage was recorded in the treatment of water spray followed by fish oil rosin + teepol, castor oil + teepol, and all these treatments were at par with the control. The treatments of Neemgold, nimbicidine, B. bassiana, cotton seed oil + teepol and NSKE 5% existed in middle order of effectiveness against the bollworm. The maximum seed cotton yield was obtained in the treatment of triazophos while minimum in the treatment of water spray.
