Abstract:

Study on effect of dates of sowing on incidence of insect pests on castor genotypes revealed that incidence of Achaea janata was observed when castor was sown either early or late, however there was a decrease in larval incidence when the crop was sown late during the month of August as compared to that during July. Maximum of 2.73 larvae were observed on 48-1 when sown early which was reduced to 1.07 with late sowing. Incidence of S. litura was high in early sown crop compared to late sown crop. In case of early sown castor, high larval population was recorded on 48-1 (3.20) and no larvae were observed on DPC-9 and in case of late sown crop high larval population was observed on DCS-9 (1.40) where no larvae were observed on DPC-9.
