Maruca infestation was seen more in Kadapa district both in blackgram and greengram. In blackgram, the genotype LBG-752 (62.2 %) and in greengram LGG-460 genotype (59.3 %) occupied more area in cultivation. Among the insecticides, the Chloropyrifos was used more i.e., 51.9 % in blackgram and 54.1 % in greengram in the Southern zone against the spotted pod borer infestation.
