: Bacillus sp. NAAS-1 isolated from the field of Chili pepper was tested for biocontrol activity against anthracnose pathogen of Chili pepper caused by Colletotrichum acutatum. The antifungal activity of Bacillus sp. NAAS-1 culture broth was compared with synthetic fungicide containing carbendazim (40%) and kasugamycin (3.45%). Bacillus sp. NAAS-1 showed a similar fungicidal activity against the anthracnose pathogen at the concentration of 50 µL/mL in comparison to the fungicide containing carbendazim (40%) and kasugamycin (3.45%) using a cup method. Bacillus sp. NAAS-1 also exhibited its potent fungicidal activity against the anthracnose in vivo test at the concentration of 50 µL/mL when compared to the fungicide containing carbendazim (40%) and kasugamycin

“…This may be due to the development of tolerance by fungicide-resistant pathogen strains ( Wharton and Deiguez-Uribeondo, 2004 ). In a previous study, anthracnose pathogens were found to be effectively controlled by prochloraz and tebuconazole, with up to 91% control achieved ( Lim and Choi, 2006 ). In contrast, propineb only inhibited 46.4% of a hypha growth strain ( Lim et al, 2009 ).…”

“…In contrast, propineb only inhibited 46.4% of a hypha growth strain ( Lim et al, 2009 ). Lim and Choi (2006) further demonstrated that the frequency of pathogen isolates that exhibit propineb resistance has increased, and pathogens that were continually exposed to the fungicide developed resistance. Moreover, the resistance isolates became more dominant within the pathogen population.…”

Anthracnose, caused by Colletotrichum gloeosporioides (C. gloeosporioides; Teleomorph: Glomerella cingulata), is the most destructive disease that affects sweet persimmon production worldwide. However, the biology, ecology, and genetic variations of C. gloeosporioides remain largely unknown. Therefore, in this study, the development of fungicide resistance and genetic diversity among an anthracnose pathogen population with different geographical origins and the exposure of this population to different cultivation strategies were investigated. A total of 150 pathogen isolates were tested in fungicide sensitivity assays. Five of the tested fungicides suppressed mycelial pathogen growth effectively. However, there were significant differences in the sensitivities exhibited by the pathogen isolates examined. Interestingly, the isolates obtained from practical management orchards versus organic cultivation orchards showed no differences in sensitivity to the same fungicide. PCR-restriction fragment length polymorphism (RFLP) analyses were performed to detect internal transcribed spacer regions and the β-tubulin and glutamine synthetase genes of the pathogens examined. Both the glutamine synthetase and β-tubulin genes contained a complex set of polymorphisms. Based on these results, the pathogens isolated from organic cultivation orchards were found to have more diversity than the isolates obtained from the practical management orchards.
