Abstract:

Organic Insecticides are environment friendly and cheap. Hence, the researchers explored the insecticidal testing of Sansevieria trifasciata as applied to Phaseolus vulgaris. This investigation determined: a) the percentages of string beans germinated after soaking the seeds in different insecticides and the plants and leaves damaged by insects b) the significant differences between and among the percentage of plants and leaves damaged by insects c) the growth of the string beans after sprayed with Sansevieria trifasciata and the significant differences between and among the efficacy of the insecticides on the growth of string beans. This study used Randomized Complete Block Design with four treatments and three blocks. Percentage was used on germination of seeds and plants and leaves damaged by insects/worms. Mean and standard deviation were used to determine the growth of string beans and analysis of variance was used to determine the significant differences in the efficacy of insecticides. The least significant difference was used to determine which insecticides were significantly different. Results showed that Sansevieria trifasciata insecticides are as effective as the commercial one. Researchers recommend that farmers/researchers should use Sansevieria trifasciata. Studies should be conducted on the insecticidal properties of the plant using other concentrations.
