| dc.description.abstract | leaf damage. The number of capsules per plant (r = -0.876**) showed a highly significant negative correlation with the mean per cent of flower and capsule damage. Consideration of leaf, flower and capsule damage, none of the genotypes/varieties were found highly resistant (HS) and highly susceptible (HS). However, variety G. Til-10 and genotype AT-457 were found resistant (R) while varieties G. Til-4 and G. Til-6 were found susceptible (S) against leaf webber, A. catalaunalis. Genotype AT-457 (1.97) and variety G. Til-10 (2.02) recorded the lowest damage score than the rest of the genotypes/varieties. The next promising varieties, AT-470 (2.49), AT-482 (2.69), AT-483 (2.71), G. Til-2 (2.80) and G. Til-3 (3.20) were fallen into the moderately resistant (MR) category. However, AT 467 (4.53) was categorized as moderately susceptible, while G. Til-4 (5.47) and G. Til-6 (5.73) had the highest damage score. Among all genotypes/varieties, the highest yield (520.13 kg/ha) was recorded from G. Til-10 than the rest of the genotypes/varieties followed by AT-457 (514.15 kg/ha) and AT-470 (477.5 kg/ha). Application of insecticides were carried out at the time of pest initiation on the crop. The data obtained from the field experiment on the management of leaf webber infesting sesame with various insecticides revealed that the maximum pest (72.22%), damaged leaf (44.19%) and capsule (9.06%) reduction over control along with the highest seed yield (692 kg/ha) and net monetary return ₹ 40710/ha was recorded in chlorantraniliprole 18.5 SC @ 0.005% treated plot. The higher larval (69.19 to 64.65%), damaged leaf (41.19 to 37.57%) and capsule (60.9 to 55.38%) per cent reduction along with higher seed yield (100.59 to 98.22%) and higher net monetary return ₹ 39100 to 38180/ha was found in the treatment of chlorfenapyr 10 SC @ 0.015% and spinosad 45 SC @ 0.0003% were statistically at par with chlorantraniliprole 18.5 SC @ 0.005%. The treatments emamectin benzoate 5 + lufenuron 40 WG @ 0.005% and novaluron 5.25 + indoxacarb 4.5 SC @ 0.016% also gave 50.50 to 43.43 per cent larval reduction, higher seed yield (48.94 to 48.31%) with higher net monetary ₹ 37260 and 36340/ha. Further, the interaction effect of various treatments and pooled period of spray (T × P), as well as interaction between different periods of spray (P), was noted as significant, which signifies that one spray is needed for managing the leaf webber population, which remained effective up to ten days after treatment. | |
