| Abstract | Phytophthora palmivora is a soil-borne pathogen that causes root and stem rot diseases in durian trees, leading to significant economic losses. Endophytic bacteria, which are non-pathogenic, can be used to control plant pathogens. The objective of this research was to test the effectiveness of Bacillus bioproducts in controlling root and stem rot disease of durian. The efficacy of four formulas, namely Bacillus subtilis BS003, Bacillus subtilis BS006, Bacillus velezensis BS011, and Bacillus siamensis BS013, in controlling root and stem rot disease was tested under greenhouse conditions. The experiments were conducted using a completely randomized design (CRD) with 8 treatments and four replications. The study compared the effectiveness of the chemical Mancozeb, commercial B. subtilis bioproduct, control (distilled water) and control checked (healthy plants). The results showed that B. velezensis BS011, applied at a rate of 100 g/20 L of water per 50 ml/tree, was highly effective, with disease incidences, disease severity indices and disease control efficacy of 1.67, 0.33 and 97.12%, respectively. Following, B. subtilis BS006, B. siamensis BS013, and B. subtilis BS003 bioproducts showed disease incidences of 8.13, 9.49 and 16.76%, respectively, disease severity indices of 1.63, 1.90 and 6.35%, respectively and disease control efficacy of 85.79, 83.44 and 44.64%, respectively. While, use of Mancozeb and the commercial B. subtilis product, which had disease incidences of 13.10 and 13.89%, disease severity indices of 2.62 and 2.78% and disease control efficacy of 77.16 and 75.76%, respectively. Whereas, the total populations of B. subtilis BS006 after 30 days of testing were high, obtaining 1.01 x 107 cfu/g of soil. |
