EFFICACY OF AFRICAN LOCUST BEAN (PARKIA BIGLOBOSA) STEM BARK POWDER ON CONTROL OF COWPEA WEEVILS (CALLOSOBRUCHUS MACULATUS) UNDER STORAGE CONDITION
Abstract
An experiment was conducted at Agronomy laboratory of the department of
Agricultural Technology Federal Polytechnic Bauchi. To evaluate the efficacy of
Stembark powder of locust bean (Pakia biglobossa) and their appropriate
concentration for the management of cowpea weevils (Callosobruchus maculatus
F.). Spintor (0.125g) was used as a positive control and untreated cowpea seeds
serving as negative control. The experiment was laid in Completely Randomized
Design (CRD) comprising of Stem bark powder (4 g, 8 g and 12 g), Spintor Dust
(0.125 g) and control. These were applied to 50 g healthy cowpea seeds and
replicated three times. Activity of the treatments were evaluated and data
collected were subjected to analysis of variance (ANOVA) using SPSS software
(version 23) and means were separated using NDMRT at 5% probability level.
The results showed that higher concentration (8 g/100g) treatment 3 significantly
