| Summary: | Yellow wilt disease commonly affects chili seedlings, with the fungal pathogen attacking the roots or stem at the soil
surface, leading to significant seedling mortality and severely impacting chili cultivation. Seed pelleting with fungicides can
mitigate the risk of fungal infection of seedlings. This study aimed to identify the type and concentration of fungicide that does
not affect seed quality while effectively inhibiting Fusarium sp. The experiments followed a completely randomized design
(CRD) with four replications. The results indicate that fosetyl-aluminium, at all three tested concentrations, inhibits (by 100%)
mycelial growth. Furthermore, seeds pelleted with fosetyl-aluminium at 0.5 g.ai. and 1 g.ai. showed higher germination
percentage, speed of germination, and shoot length, compared to non-pelleted seeds under laboratory conditions. In greenhouse
conditions, seeds pelleted with fosetyl-aluminium at 0.5 g.ai. demonstrated higher germination percentage, speed of germination,
and shoot length, compared to non-pelleted seeds. Both laboratory and greenhouse assessments showed that seed pelleting with
fosetyl-aluminium at all concentrations significantly inhibited Fusarium sp. compared to non-pelleted seeds. Thus, pelleting
seeds with fosetyl-aluminium at 1 g.ai. is recommended for enhancing seed quality and effectively inhibiting Fusarium sp. in
chili seedlings. |
