LUDHIANA _ The increased incidence of the rice planthoppers viz. whitebacked planthopper and brown planthopper, has been observed in various rice growing districts of Punjab like Taran Tarn, Amritsar, Sangrur, Patiala, fatehgarh Sahib, Mansa, Ferozepur and Moga. Divulging this, Dr Balwinder Singh, Head, Department of Entomology, PAU, told that almost all the rice varieties, recommended as well as unrecommended, are found to be infested with planthoppers. In view of this, he advised the farmers to regularly monitor their rice/basmati field for planthoppers. Dr Singh asked the farmers to stick to the recommended sprays for the control if hopper population exceeds ETH levels (5 hoppers/hill).  Use at least 100-120 litres of water for spraying and direct the sprays towards the plant base, as far as possible, suggested he. Advising that not to mix synthetic pyrethroids with recommended insecticides for they induce planthopper resurgence, Dr Singh told that the insecticides recommended for the control of rice planthoppers include Confidor 200SL (imidacloprid) @ 40 ml/ acre, Eklaux/Quingurad 25EC (quinalphos) @ 800 ml/ acre and Dursban/Coraban 20EC @ 1.0 l/acre.
