Effect of planting date of rice on brown planthopper

Abstract

Experiments were conducted to evaluate effect of planting date of rice on brown planthopper incidence at the ICAR- Indian Agricultural Research Institute, New Delhi during kharif 2016 and 2018. The results revealed that first planting (5–8 July) significantly reduced the pest incidence followed by second (18–23 July) and maximum incidence was observed in third planting (5–7 August). Early to normal planting thus can avoid higher BPH infestation, thereby preventing avoidable yield loss.
