Many fields in Trung Mon commune (Yen Son) surround the fields with plastic to prevent rats from biting newly transplanted rice.

After transplanting, spring rice is susceptible to a number of diseases such as thrips, fruit flies, root rot, mice, and yellow apple snails. Among them, harmful rats and golden apple snails are the main causes of damage to newly transplanted spring rice. If there are no timely prevention measures, it can cause great damage to spring rice production - the main production season, which is decisive to the output target of the whole year.

According to statistics, the area of rice damaged by golden apple snails is over 20 hectares, of which the main tea season area is over 5 hectares, the area damaged by late tea is 15 hectares, mainly in Son Duong, Ham Yen and Tuyen Quang city.

According to the Provincial Agricultural Extension Center, in addition to yellow apple snails and rats that damage spring rice, sudden changes in temperature at this time can cause spring rice to contract a number of diseases such as root rot and thrips. This unit recommends that farmers regularly visit fields and apply integrated prevention measures such as cultivating, cleaning weeds around fields, clearing mud, watering properly, fertilizing fully and at the right time and spraying chemicals. Protect plants and prevent diseases at the right time and in the right dosage, ensuring the best conditions for rice plants to grow and develop.
