Management of tomato pests using effective macrooganism (EM) bio-pesticide as alternative pests control method in Bambili, Cameroon

Tuta absoluta, Bemisia tabaci and Macrosiphum eurphorbiae are important pests of tomato in Cameroon. The effect EM a biopesticide containing Bacillus thuringiensis as active ingredient was evaluated on the suppression these pests. A completely randomized design with 4 treatments [control (T0); 10 ml/l (T1); 20 (T2); 30 (T3)] 3 replications were used. sprayed weekly for seven weeks. variation insects’ populations, T. absoluta impact plants growth different plots compare using ANOVA test. Different concentrations B. effective reducing populations significant difference observed within (DF =3, F=258.69, P=0.0000; DF=3, F=368.50, P=0.0000 F=44.21, P=0.0000) respectively. On untreated control T0, three showed an exponential expansion 7 No plant growth. This biological pesticide can save alternative sustainable production.
