Impact of transplanting dates on incidence of major insect pests of Cabbage



Impact of transplanting dates on incidence of major insect pests of Cabbage







The minimum infestation of aphid and larval population of diamondback moth was recorded on early crop transplanted on 26th September followed by 3rd and 10th October transplanted crop and maximum infestation was on late crop transplanted on 24th October. Highest yield of cabbage heads was obtained from the crop transplanted on 10th October, while minimum yield was in late transplanted crop. The aphid and larval population of diamondback moth had significant positive correlation with transplanting dates of cabbage crop. On the other hand, the transplanting date and incidence of aphid and diamondback moth showed significant negative correlation with the yield of cabbage heads means, with the delay in transplanting, dates incidence of pests increased and yield of cabbage heads decreased.
