STUDIES ON SEASONAL INCIDENCE AND MANAGEMENT OF MAJOR PESTS OF MAIZE

Investigations were carried out to study the “Seasonal incidence andevaluation of insecticides against major pests of maize” at the Department of Agricultural Entomology, College of Agriculture, Parbhani during Rabi 2018-19.The population of aphid ranged between 0.00 – 48.9 per three leaves and first appearance was noticed in 1 st SMW and reached at its peak at 3rd SMW (15-21 JAN) i.e. 48.9 aphids /3leaf. The first appearance of Fall armyworm was noticed in1 st SMW (16 larvae /10 plants) thereafter it was increased gradually and reached its peak (22 larva /10 plant) in 6 th SMW. The cumulative mean data suggested that emamectin benzoate 5SG (2.28 larva /10 plant ) proved effective with minimum infestation of Fallarmyworm and found at par with chlorantraniliprole 18.5 SC (2.69 larva /10 plant )and flubendiamide 39.35 SC (3.21 larva /10 plant), thimethoxam 12.6 + lambdacyhalothrin 9.5 ZC (4.95 larva /10 plant), indoxacarb 14.5 SC (5.47 larva /10plant), spinosad 45 SC (5.62 larva /10 plant) and profenophos 50 EC (6.96 larva/10 plant) appeared as next better treatments in this respect respectively. Maximuminfestation of Fall armyworm was recorded in water spray (18.10 larva /10 plant).
