Spraying in paddy after rain to prevent germination is a common practice among farmers in rice-growing regions. The reason behind this practice is to avoid the pre-germination of the seeds when they are not yet ready to be planted.
Before planting rice seeds, it is essential to prepare the paddy field by ploughing the soil and leveling it properly. Once the field is ready, the rice seeds are sown in the soil and covered with a layer of soil. However, if there is a heavy rainfall after sowing the seeds, it can lead to the pre-germination of the seeds, which can cause the seeds to rot or get damaged before they can sprout.
To prevent this from happening, farmers often spray the paddy field with certain chemicals or pesticides after a heavy rainfall. These chemicals help to inhibit the germination of the seeds and protect them from getting damaged by the excess moisture in the soil.
However, it is important to note that the use of chemicals or pesticides should be done with caution, as they can have negative effects on the environment and the health of the farmers. Therefore, it is essential to consult with agricultural experts or local authorities before using any chemicals on the paddy field.
In conclusion, spraying in paddy after rain to prevent germination is a common practice among farmers to protect the rice seeds from pre-germination and ensure a successful harvest. However, it is important to use chemicals responsibly and seek professional advice to minimize any negative impacts on the environment and human health.
