Currently, spring rice has basically finished flowering, early tea areas are in the ripening stage, some areas are ready to harvest; the majority are in the milky to green stage.

For rice fields with brown planthoppers, after draining the water in the field, it is necessary to erect trees and tie them in bundles according to the tilt of the rice plants. (illustrative photo)

On May 19, the province had moderate to heavy rain, and in some places very heavy rain, with rainfall ranging from 30 to 50mm, with high rainfall in places like Vu Hoa commune (Kien Xuong) reaching 88.8mm, causing some spring rice fields to tilt and fall, mainly in the rice fields that ripened at the end of April.

The agricultural sector recommends that localities urgently drain water in the fields, do not drain immediately but maintain a shallow layer of water to keep the rice plants, especially the newly emerged rice areas until they are green and firm. The rice areas that have fallen slightly can recover on their own. The rice areas that have fallen, after draining some water in the fields, need to be erected, tied in the direction of the rice plants' tilt, absolutely do not erect them in the opposite direction of the fallen rice plants, which will break the rice roots, greatly affecting the process of grain firming. It is necessary to regularly check for planthoppers and brown spot disease to proactively spray and control them in time.

The rice area is 70% or more ripe, if there is brown spot, after draining the water, the weather is clear, so it should be harvested promptly and put into the dryer immediately to limit the rice grains from being too wet to dry, reducing the quality of the rice. The rice area is slightly browned or not browned should be harvested when it is 80 - 85% ripe according to the motto "green at home is better than old in the field". The rice area is in the flowering stage or has just finished flowering, so it is necessary to proactively spray to prevent neck blast disease with susceptible rice varieties such as BC15, TBR225, TBR1, various types of glutinous rice, ... and combine to prevent grain smut with other rice varieties when the weather is clear.
