Abstract

Investigation on development of suitable integrated pest management module for major insect pest of cabbage (Brassicae oleracea var. capitata) was carried out in experimental field of Navsari Agricultural University, Navsari, Gujarat. In case of larval population of C. binotalis, S. litura, P. xylostella and H. armigera was found in sole synthetic insecticide module M₃ (0.23, 0.35, 1.61 and 1.78/plants, respectively) followed by eco-friendly pest management module M₁ (0.23, 0.98, 1.50 and 1.51/ plants, respectively) and botanicals bio-pesticides module M₂ (0.30, 0.99, 1.62 and 1.65/ plants, respectively). As far as yield and economics is concerned, module M₃ recorded highest yield of cabbage heads (28322.0 kg/ha) and consequently higher net gain over control (122050 Rs./ha) and higher net BCR (1:41.01). However, its effect in destructing natural fauna, polluting environment and causing residual problem should not be overlooked. Eco-friendly pest management module and botanicals and bio-pesticides module was next effective module in recording yield and net profit besides any adverse effect on natural fauna and did not leave any toxic residue.

Abstract

Eleven different insecticides were evaluated for their efficacy against A. craccivora at Regional Horticulture Research Station, ASPEE College of Horticulture and Forestry, Navsari Agricultural University, Navsari, Gujarat during Rabi season of the year 2013-2014. The treatment imidacloprid 0.005 per cent (0.19 aphid index/plant) was found to be most effective followed by thiamethoxam 0.01 per cent (0.33 aphid index/plant). Verticillium lecanii 0.40 per cent (0.58 aphid index/plant), azadirachtin 0.002 per cent (0.62 aphid index/plant) and dimethoate 0.03 per cent (0.77 aphid index/plant) were the next in order. The highest marketable pod yield (30.37 q/ha) and maximum per cent increase in pod yield of cowpea over control (84.28 %) was recorded from the plots treated with thiamethoxam 25 WG @ 0.01 per cent.

Abstract

Studies were carried out on screening of some genotypes of brinjal for their relative resistance against jassid and whitefly on brinjal (Solanum melongena L.) at Regional Horticultural Research Station Farm, NAU, Navsari during 2011-12. The results revealed that out of fourteen genotypes of brinjal, the genotype AB-8/5 (6.65 jassids/three leaves) recorded the lowest population of jassids and genotype AB-8/6 (5.93 whiteflies/three leaves) recorded lowest population of whiteflies.
