Assesing the Efficacy of Aqueous Leaf Extract of Some Botanicals for Control of Field Insects of Watermelon (Citrillus lanatus) In Southern Guinea Savanna, Nigeria
並列摘要
Field trials were conducted during 2009 and 2010 rainy season to assess the efficacy of leaf extract of some botanicals for production of watermelon (Citrillus lanatus) in Southern Guinea Savanna Nigeria. The treatments consisted of leaf extracts from 3 botanicals: Bush tea (Hyptis suaveolens), Moringa (Moringa oleifera) and Pawpaw (Carica papaya) and one synthetic insecticide Labdacyalothrin (karate). The experiment was laid in a Randomized Complete Block Design (RCBD) and replicated 3 times to form fifteen plots. The results showed that, there was significant effect among the different botanicals used on all the parameters assessed except on the vinelength of watermelon, at various stages of growth in both years. Application of leaf extract of pawpaw gave better performance in all the parameters assessed when compared to the other botanicals in both years. Application of karate produced the best results in both years; while poor result were obtained from the control plots. Application of pawpaw leaf extract conferred high protection on the fruit when compared to other botanicals, which is statistically similar with result of karate in both 2009 and 2010 cropping season. Pawpaw leaf extracts appears to be a better botanical option in watermelon production.
