Fusarium wilt on chilli
Recognize the problem
wilting and drying of chilli plants. The disease is difficult to control
effectively because it is soil-borne and can spread to other fields. This
disease is common in several crops.
Chilli is an export crop which can provide a high income
for farmers. Infection with Fusarium can result in yield losses of 20-30%. Fusarium
disease can survive for many years in soil or plant residues. There are very
few varieties of chilli that are genetically resistant to this disease. Fusarium
spreads rapidly by water flow, rain splash and by movement of infected soil
or plant material, especially seeds.
Use certified seeds
- Seed treatment with fungicides such as benomyl (e.g.
Benlate at 100-200g/ acre) or carbendazim (e.g. Bavistin at 150-250cc/ acre)
- Reduce the nitrogen fertilizers dose to 112 lb/Acre to reduce the disease
- Apply Trichoderma
viride to the soil twice per crop season. Apply for the first time at
land preparation and the second time at planting.
- Collect and burn any infected plants
- Maintain the pH level of the soil
- Do not apply any chemical fungicide at the time of
harvesting, or when applying Trichoderma
as the chemical will affect this
When using a pesticide, always wear protective clothing and follow the instructions on the product label, such as dosage, timing of application, and pre-harvest interval.
