Que Phong deploys to control brown planthopper epidemic that damages hundreds of hectares of rice
(Baonghean.vn) - After discovering the brown planthopper situation in rice, specialized departments of Que Phong district sent staff to the rice fields, worked with local authorities to inspect and promptly implement epidemic control.
Field inspections of rice fields in Tri Le commune with officers from the Department of Agriculture and Rural Development and the Que Phong District Agricultural Service Center showed that as of September 14, 2023, the rice areas damaged by brown planthoppers in the commune had been controlled, with no signs of spreading.
Mr. Lu Van Cuong - Vice Chairman of Tri Le Commune People's Committee also said that on September 13-14, officials of the District People's Committee and the Agricultural Service Center also went to the place to check and provide instructions on preventing the spread of the disease. In villages with large rice growing areas such as Kem Don, Nong village, Cam village, Lien Hop, Lam Hop, local authorities always remind people to visit the fields, promptly detect areas affected by pests and have sprayed pesticides to limit damage and spread.
Mr. Phan Xuan Hung - Deputy Director of the Que Phong District Agricultural Service Center said that through understanding the situation and directly inspecting the locality from September 13-14 in Tri Le commune, it was found that this is an area where the rice area damaged by brown planthoppers is not much, and has basically been controlled. The Center has guided and coordinated with the locality to deploy people to spray pesticides.
In Chau Kim commune, according to the leader of the commune People's Committee, the current brown planthopper epidemic is quite severe on an area of about 47 hectares of rice. The locality has instructed people to spray pesticides to prevent the spread of the epidemic. In addition, some areas with light planthopper infection have also been sprayed for prevention and continue to closely monitor the developments.
According to statistics from the People's Committee of Que Phong district, as of September 15, 2023, the 2023 winter-spring rice crop in the district is in the stage of heading, a small area has blossomed. Through the joint inspection of the Agricultural Service Center and the Department of Agriculture and Rural Development of the district, a number of pests and diseases have appeared on the current winter-spring rice crop such as: various types of planthoppers, 6th generation of small leaf rollers... The average density of planthoppers is from 700-800 individuals/m2, high places 1,500-2,000 individuals/m2, in some places up to over 3,000 individuals/m2. Planthoppers are mainly adult and larval stages. There are both white-backed and brown planthoppers, however the number of white-backed planthoppers is higher than that of brown planthoppers.
The infected area according to the communes' reports and through the actual inspection of professional staff is more than 1,437 hectares. Of which, about 678 hectares are lightly infected, about 466 hectares are moderately infected, about 357 hectares are heavily infected, some areas have been burned. The cause was initially determined to be that it had not been sprayed, or the wrong type of pesticide was sprayed, the spraying was not uniform, and in addition, the weather was quite complicated...
Que Phong District Agricultural Service Center also forecasts and disseminates to people the developments of pests and diseases and measures to prevent and control them, not allowing the disease to spread strongly.
In Que Phong, the reality shows that compared to previous years, this year, planthoppers and leaf rollers appear earlier and it is forecasted that in the coming time, with the alternating sunny and rainy weather conditions and the current source of planthoppers, it will create conditions for planthoppers to continue to increase their density and cause widespread "planthopper burn" if not sprayed in time. On the other hand, the 6th generation of leaf rollers has a phenomenon of overlapping many generations, so it is forecasted that in the coming time, the 7th generation of leaf rollers may appear during the flowering stage of the summer-autumn rice crop. This is a stage that greatly affects productivity.
Therefore, the district's professional staff are continuing to urge and direct the People's Committees of communes and towns to simultaneously spray and eliminate rice areas infected with planthoppers with a density of 1,000 insects/m2.2for pre-flowering rice areas, and 2,000 individuals/m2or more for areas from the flowering stage and in the ripening stage. Spray to kill small leaf rollers with a worm density of 50 insects/m2or more for rice areas in the pre-flowering stage and 30 individuals/m2or more for post-harvest areas.
The District Department of Agriculture and Rural Development, the Agricultural Service Center, and the People's Committees of communes and towns continue to closely monitor and inspect the situation of planthoppers to advise on timely treatment measures and minimize the damage caused by pests. In particular, pay attention to monitoring the development of the 6th generation of small leaf rollers to provide timely recommendations and prevention measures.
The Que Phong District Agricultural Service Center has also advised the District People's Committee to issue telegrams and official dispatches on pest and disease prevention; report production progress to the Nghe An Department of Plant Protection and Development. The Center has also collected white-backed planthopper samples and sent them to the Nghe An Department of Crop Production and Plant Protection to test for Black-striped Dwarf Virus and the results were negative on August 1, 2023.
