Synthetic pyrethroids vis-a-vis tungro and yellow borer control in rice


, : Synthetic pyrethroids vis-a-vis tungro and yellow borer control in rice. Rice Research Newsletter 8(2-3): 5, 7-9

Six pyrethroid insecticides were tested in sprays against Nephotettix virescens and N. nigropictus (the vectors of rice tungro virus) and Scirpophaga incertulas on rice in India.
