Abstract:
Chilli (Capsicum annuum L.) (Family: Solanaceae) is one of the important spice crops of India and is being widely cultivated throughout warm temperate, tropical and subtropical countries. Chilli hybrids were raised during the year 2013 with standard agronomic practices to study the effect of Vermicompost (5t/ha) on the activity of chilli mite, Polyphagotarsonemus latus. The present investigation reported that the P. latus population was decreased the number of eggs laid by P. latus significantly (5.05 eggs/leaf) in comparison to control (no fertilizer; 6.18 eggs/leaf). Statistically significant control was recorded in the vermicompost treatment @ 5t/ha which reduced 18.28 percent egg laying and 21.16 percent mobile stages of P. latus population on chilli plants. Recommended dose of NPK treatment was not found to be effective in reducing the P. latus population during the present investigation. The organic sources of nitrogen, especially vermicompost, contain major and minor plant nutrients in available from that makes the plant system defensive against pest infestation.
