Chemical control of two spotted spider mite Tetranychus urticae (Acari: Tetranychidae) on rose under polyhouse conditions

Sarbmeet Singh, RS Rana, KC Sharma, Aarti Sharma and Arvind Kumar

Rose is an ornamental plant of great commercial value and large number of insect pest attacks its cultivation. Among them two-spotted red spider mite Tetranychus urticae Koch is a ubiquitous species present worldwide and considered a key pest for rose and other ornamental plants. Nymphs and adults of the mite feed with chelicerate type of mouthparts which pierce and suck the cell sap from epidermis of leaves. Webbing around flowers can be seen after the heavy attack of the mite. An experiment was conducted to evaluate bio-efficacy of six pesticides against red spider mite on rose under poly house conditions. Fenazaquin at 0.0025% concentration was found to be most effective while HMO at 0.5% concentration was least effective in control of the two spotted spider mite. The order of effectiveness of treatments based on per cent reduction of mite were fenazaquin (0.0025%) > propargite (0.0057%)> HMO (2.5%)> dimethoate (0.03%)> HMO (2%) > dicofol (0.05%)> imidacloprid (0.015%)> HMO (1.5%)> HMO (1%)> HMO (0.5%), respectively.
