Consortium solid formula of bacillus spp. to control bacterial wilt on chili plants

Abstract

Due to its high economic worth and ability to be consumed in both fresh and processed forms, chili (Capsicum annum L.) is a fruit that is frequently used as a vegetable. Pests and plant diseases, such as bacterial wilt caused by Ralstonia syzygii subsp. Indonesiensis, are the causes of reduced chili productivity. Plants will eventually perish as a result of symptoms like withering of the leaf tips that eventually spread to the undersides of the leaves. The lower vascular tissue and roots of the affected chili plants appear brown. Bacterial wilt is an important disease of chili caused by Ralstonia syzigii subsp. indonesiensis and can reduce yield by up to 90%. The research aimed to obtain the best solid formula consortium of Bacillus spp. for controlling R. syzygii subsp. indonesiensis on chili peppers. The study consists of 2 stages: 1). Production of a consortium combination of Bacillus spp. in solid waste 2). Test the ability of the consortium of Bacillus spp. in solid waste to control bacterial wilt in chili plants. The study used a completely randomized design that consisted of 19 treatments and four replications. Each treatment was introduced on chili seeds and seedlings, while the inoculation of R. syzygii subsp. indonesiensis was conducted on chili aged 35 days after planting. The results showed that the best solid formula consortium of the Bacillus spp. for controlling bacterial wilt (R. syzigii subsp. indonesiensis) on chili plants is the Bran + Bagasse formula for four weeks of storage.
