Crop blast is a serious problem that often affects the paddy crop. It is a fungal disease that can significantly reduce the yield of crops and also impact the quality of harvested grains. However, there are various ways that farmers can use to control blast in their paddy crops. Here are some effective measures:
1. Use resistant varieties
Farmers must select and cultivate paddy varieties that are resistant to blast disease. Different varieties of paddy have different resistance levels to the disease, so it is essential to choose the ones with a high level of resistance.
2. Maintain crop rotation
Crop rotation is an effective way to control blast disease. Farmers should avoid planting rice crops repeatedly in the same area since the infection can build up in the soil and affect the crop. Planting other crops in between rice cultivation can help break the cycle of disease and control its spread.
3. Proper field management
Proper field preparation and management can help control blast disease in paddy crops. Farmers should maintain appropriate drainage in the field and avoid over watering, which can create a favorable environment for the disease to spread. They should also remove plant debris and stubble after harvest to prevent the build-up of the disease in the soil.
4. Use of fungicides
Fungicides are an effective measure to control blast disease in paddy crops. Farmers should apply fungicides when the disease appears, and the weather is favorable for disease development. They must ensure that they apply the recommended dosage and follow the instructions for usage to avoid any adverse effects on the crop.
5. Timely harvest
Harvesting should be done at the right time. Delayed harvesting can lead to an increased risk of the crop being affected by blast disease. Farmers should harvest the crop when it is in the recommended maturity stage to avoid the risk of infection.
In conclusion, controlling blast in paddy crop requires proper field preparation, crop rotation, and timely application of fungicides to prevent the disease from infecting the crop. Farmers should follow the recommended practices to ensure a healthy and productive harvest.
