About the Practice

Surface grass hoppers feeds on the leaves and tender parts of pearl millet (Pennisetum typhoides) crop. Heavy attack of these insect pest leads to economic losses of the crop. Rainy season favors the multiplication of this pest. For the control of this pest, caster (Ricinus communis) cake is grinded and dusted in the affected pearl millet crop.

PAS 1:

"The results of the present study showed that castor bean plant extracts and oil could be toxic to larvae of P. xylostella through contact and ingestion. Plant based pesticides have been found to exhibit larvicidal effects (e.g., Kétho et al., 2002; Sanda et al., 2006; Ogendo et al., 2008; Agboka et al., 2009). Under field conditions, Sanda et al. (2006), find that Cymbopogonschoenanthus L. could significantlyreduced larval population of P. xylostella. Torres et al. (2001) report 100% mortality against P. xylostella larvae with 10% aqueous solution of the wood bark of A. pyrifolium in Brazil. Using aqueous extracts from leave of R. communis, Aouinty et al. (2006) have reported high larvicidal activity against 2nd and 4th instar larvae of four mosquito species, Culexpipiens (L.), Aedescaspius (Pallas), Culisetalongiareolata (Aitken) and Anopheles maculipennis (Meigen).

PAS 2:

"The insecticidal value of the castor oil plant (Ricinuscommunis) in controlling the termites which damage the wood of Mangiferaindica and Pinuslongifolia was examined. In comparative trials, the order of insecticidal activity was DDT=BHC > castor oil + castor cake (1:1) > castor oil > castor leaves > castor cake >neem oil >neem leaves. All treatments significantly reduced weight loss in wood pieces exposed to termites."
