ABSTRACT
Whitefly cause loss yield of chili 20-100 %. As a vector, whitefly cause pepper yellow leave curl virus disease. The bacterial endophyte Bacillus spp. have been reported effective to control whitefly. To be stored for long time the bacteria should be in an formulation. The purpose of this study was to obtain the best formula for endophytic bacteria Bacillus pseudomycoides sp. nov. strain SLBE1.1SN and the best storage period to control whitefly and to increase the growth and yield of chili plants. The research method have been used a completely randomized design (CRD) with 26 treatments and 3 replications. The treatment consisted of 3 kind of carrier material for formulation of endophytic bacteria such as bagasse rice bran, rice straw and 3 combinations of each carrier (1:1 w/w) storage period (0, 2, 4, and 6 weeks), insecticides (Imidacloprid), and control. The formulation was introduced in the seed (seeding) and seedlings (planting) of chili. Whitefly was bred and infested before planting in the area. The variable were observed the viability of B. pseudomycoides sp. nov. strain SLBE1.1SN in the formula, population development of whitefly (eggs, nymph and imago). The results showed that the best formulation of the endophytic bacteria B. pseudomycoides sp. nov. strain SLBE1.1SN in control whitefly are rice straw stored for 4 weeks, has almost the same ability as insecticides.
Key words : Bacillus pseudomycoides sp. nov. strain SLBE1.1SN, chili, solid formulations, whitefly.
