Castor (Ricinus communis); whitefly Trileurodes ricini Misra ;Wax bloom, Quinolphos, Profenophos, Neem, Pongamia and Mahua

Castor is an important oilseed crop. The castor bean contains about 50-55% oil. Among vegetable oils, castor oil is distinguished by its high content (over 85%) of ricinoleic acid. No other vegetable oil contains so high proportion of fatty hydroxy acids. Castor oil’s unsaturated bond, high molecular weight (298), low melting point (5°C), and very low solidification point (-12°C to -18°C) make it industrially useful, most of all for the highest and most stable viscosity of any vegetable oil. The castor plant has a substantial taproot with many lateral branches which can reach a great depth enabling them to withstand drought and harsh weather conditions. Leaves of castor plants are large, glossy, and green with pointed lobes and prominent veins; However, the castor leaf for many years has often been attacked by the whitefly and in most cases leads to the destruction of the plant. The whitefly causes stunted growth of the plant and yellowing of leaves which renders the shedding of fruiting bodies. Among the eight treatments, the lowest whitefly/plant recorded by The T4 quinolphos and T6 Neem oil 2% recorded as the best treatments over the rest of the treatments. Significantly highest grain yield @3730.00 kg and 3627.63 kg was recorded by T6 Neem oil 2% and T7 Pongamia oil 2% followed by T5 Mahuva oil recorded yield @ 3283.30kg. However, the chemical treatments viz., T3 Profenophos 50 EC @0.03% and T4 quinolphos 25 EC @ 0.05% recorded yield @ 2956.66 and 2936.00 kg/ha both at par with each other. Whereas untreated control recorded the lowest yield @2426.03 kg/ha.
