STUDIES ON SEASONAL INCIDENCE AND MANAGEMENT OF MAJOR PESTS OF MAIZE.

      Аннотация: 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).
