Screening of mung bean genotypes against leaf folder (Lamprosema indicata) in terai region of West Bengal

Screening of twenty four (24) genotypes of mung bean was carried out in pre-kharif and post-kharif seasons over two years i.e. 2003 and 2004 in terai region of West Bengal to evaluate resistance to leaf folder (Lamprosema indicata). The genotypes A-228(0.07–0.57), SLM-70(0.13–0.37), MLD-95-21 (0.07–0.53) and A-43 (0.10–0.43) in pre kharif season and A-33 (0.07–0.50), SLM-70 (0.10–0.57) in post kharif season were found less infested. The genotypes like Pusa-96-32 (0.47–1.43), PDM-84-143 (0.40–1.43) in pre-kharif season and Pusa-96-32 (0.37–0.90), PS-16(0.30–0.70), and NBM-100 (0.17–0.73) in post-kharif season were found susceptible. Phenol, OD phenol, K, P content and trichome in leaf surface had negative and N content had positive impact on infestation.
