Fungal diseases are a major problem that can affect paddy yield and quality. Controlling these diseases is critical for the success of any paddy cultivation. Here are some information on how to control fungal diseases in paddy.
1. Seed treatment: Fungal diseases can be prevented by treating the seeds before sowing. This can be done by using fungicides like Bavistin or Thiram. These chemicals can be mixed with the seeds and placed in a container for five minutes before planting.
2. Crop rotation: Crop rotation is a good method to control fungal diseases. By rotating different crops, the chances of fungal diseases being passed on from one crop to another are reduced. This also helps to maintain soil fertility and reduce soil-borne diseases.
3. Cultural practices: Cultivation practices like planting dense crops, avoiding overcrowding, regular pruning, and weed control can help prevent fungal diseases. Watering regularly and avoiding excessive moisture also helps.
4. Fungicides: If the fungal disease has already infected the paddy crop, the use of fungicides is necessary. Fungicides like Propiconazole, Hexaconazole, Tebuconazole, and Tricyclazole are used to control these diseases. However, these fungicides should be used judiciously and following the instructions of the manufacturers.
5. Biocontrol agents: Biocontrol agents like Trichoderma viride and Pseudomonas fluorescens can also be used to control fungal diseases. These agents help to suppress the growth of fungi and protect the plants from further damage.
In conclusion, the control of fungal diseases in paddy is a constant battle, but employing good cultivation practices, seed treatment, and judicious use of fungicides/biocontrol agents can help minimize losses and improve yield and quality.
