ABSTRACT The influence of different planting dates was studied on major bollworms (Earias spp. & Pectinophora gossypiella) attacking valuable commercial cotton crop. Susceptible Gossypium arboreum variety HD 432 was planted on three different date of sowing at fortnight intervals starting from April to May. Incidence of Spotted bollworm in green bolls was observed least (12.07 & 13.08%) in first fortnight of April sown crop as compared to May sown crop (19.52 & 21.91%) during 2018 and 2019, respectively. Pink bollworm also showed a similar trend and damage (bolls and locules) was minimal in the crop sown in April compared to the crop sown in May during both cropping seasons. This study highlights the importance of sowing date in the pest management scenario by defining the final level. |
