Protect spring rice from pests and diseases

Farmers in Mai Ha commune (Mai Chau) increase care and fertilization to increase resistance for spring rice.

According to the forecast of the National Center for Hydro-Meteorological Forecasting, the weather will continue to be complicated, with widespread rain in April and less intense heat than the average of many years. Therefore, there is a risk of affecting the growth and development of rice plants as well as the development of some major harmful organisms such as: rice blast disease, planthoppers, rats, leaf rollers, silver leaf disease, bacterial streak spots... with a tendency to increase in density and rate of damage, affecting rice yield and quality if there are no timely preventive measures.

Through inspection in Luong Son district, the functional unit discovered that the main pests that arise and cause damage to spring rice are: harmful rats, rice stem borers, thrips, and groups of planthoppers... causing scattered damage. Comrade Nguyen Thi Minh, Head of the Department of Agriculture and Environment of Luong Son district, said: To ensure the productivity and quality of spring rice, the district has directed communes and towns to closely monitor the situation of pests and diseases, regularly inspect fields, grasp the developments and development of pests and diseases, especially brown planthoppers, leaf rollers, blast disease, and silver leaf... Assign technical staff to coordinate and grasp the crop schedule and the status of each rice crop. Promote propaganda and instruct farmers on the use of pesticides to prevent and control pests on rice...

In the whole province, according to statistics from the Plant Protection Department, rats continued to damage an area of ​​85 hectares, distributed in Hoa Binh city, Lac Son, Lac Thuy, Luong Son districts (an increase compared to the previous period); stem borer flies affected an area of ​​5 hectares in Luong Son district; root strangulation occurred and damaged an area of ​​5 hectares, a decrease compared to the previous period; rice blast disease occurred and damaged nearly 13 hectares in Lac Son district. Other pests such as planthoppers, leaf rollers, thrips, etc. caused minor damage scattered in localities.

To be proactive in directing production and minimizing damage caused by pests, the Plant Protection Department has just issued Official Dispatch No. 156/TTBVTV on proactively managing some major pests on spring rice in 2025. Accordingly, district-level specialized agencies actively direct the grassroots and guide farmers to closely follow the fields, grasp the developments and development trends of rice blast, bacterial leaf blight, and brown spot. Classify the age of the worm, determine the time of peak maturity for each area, determine the egg density, hatching rate, and parasitism rate to forecast the trend of worm density in the coming time, as a basis for effective control. At the same time, classify each rice crop and each field, determine the area of ​​rice affected by pests and diseases that need to be controlled to minimize damage.

Comrade Vu Thi Anh Dao, Deputy Head of the Provincial Plant Protection Sub-Department, said: Localities should pay attention to directing the professional team to guide farmers to take advantage of favorable weather to care for, weed, and fertilize rice fields in a timely manner according to technical procedures. Fertilizing with a full balance of nitrogen, phosphorus, and potassium helps rice grow and develop well, increases resistance, overcomes root suffocation, and limits late-season pests and diseases. Rats are currently the largest rice pests in the regions. Farmers should be instructed to clean up and clear bushes, weeds around banks and ditches to limit hiding places and breeding grounds for rats. Mobilize localities to handle and catch rats en masse, and use one of the drugs on the list of drugs allowed for use in Vietnam to register to control this type of pest. Priority should be given to using drugs that are less toxic to the environment, and use according to the instructions on the packaging...
