Chilli is one of the most important spices in Vietnam, especially in Thua Thien Hue. Chilli production is threatening by bacterial wilt caused by Ralstonia solanacearum which leads to significant reduction of the productivity and economic efficiency. Growers in Thua Thue Hue mainy rely on chemicals, for example Novinano 55 WP. to control the disease. In this study, a brassica plant (Brassica juncea) amended in soil was used to compare its ability in controlling bacterial wilt disease with Novinano 55 WP and to assess its effects on the growth and development of chilli. Results showed that brassica plant significantly controlled the disease with the control efficacy of over 80 percent which was higher than that of Novinano 55 WP and the untreated control. In addition, brassica plant also served as green manure promoting growth and development of chilli. Therefore, soil amendment with brassica resulted in higher yield and eventually higher profits for growers than the untreated control and Novinano 55 WP.
