EFFICACY OF BOTANICAL DUST AGAINST PULSE BEETLE OF BLACK GRAM (Vigna mungo L.)

Abstract

The study aims to devise suitable and eco-friendly control measures for pulse beetle. For this, the experiment was carried out in Central Agricultural Laboratory, Hariharbhawan, Lalitpur from April 2020- June 2020. The experiment was laid out in a Completely Randomized Design with four replication and six treatments (Xanthoxylum armatum DC fruit dust@ 50gm kg-1; Acorus calamus L. rhizome dust@ 50 gm kg-1; Curcuma longa L. rhizome dust@ 50 gm kg-1; Azadirachta indica A. Juss. leaf dust@50gm kg-1; malathion dust@ 1gm kg-1 and control). Out of four botanical dust, bojho rhizome was found more effective than Malathion (positive check) with minimum insect build-up (0.00) and minimum loss (0.00%). It was effective in maintaining higher germination (92.5 percent) and lower moisture content (11.25). X. armatum fruit dust and A. indica leaf dust were found ineffective to cause adult mortality (56.25 and 59.37) in black gram. Thus, botanical materials such as A. calamus rhizome dust has been found as effective safe alternatives for the management of C. chinensis L. in the storage of black gram.
