The “Doi Kham” research team is awesome! Two new strains of viruses were discovered in strawberries of Royal Award 80 variety for the first time in Thailand.
Researchers at Doi Kham Food Products Co., Ltd. discovered strawberry latent ringspot virus (SLRSV) and strawberry crinkle virus (SCV) in 80 royal strawberry varieties, the cause of leaf spot disease. and wrinkled leaves in three farmers’ cultivation areas, namely Ban Nong Tao, Ban Khop Dong, Mon Pin Subdistrict, and Ban Mae Ngon Khilek, Mae Ngon Subdistrict, Fang District, Chiang Mai Province. It is the first discovery in Thailand.
Mr. Niwat Khantho, Agricultural Innovation Manager, said, “This discovery Due to the fact that the company Collaborate with the Department of Agricultural Science Mahidol University Department of Entomology and Plant Pathology, Faculty of Agriculture Chiang Mai University Studying and developing strawberry varieties at the Company’s Plant Research Laboratory (LAB), which found problems with leaf spots, curling, and stunting in strawberries. 80 royally bestowed varieties that are important factors for growth and production volume which affects the market value SLRSV and SCV viruses were detected: which no one has ever encountered in this type of plant.”
The Plant Research Laboratory (LAB) is located in the area of the Royal Instant Food Factory No. 1 (Fang), Chiang Mai Province. For use in studies, research and development of economic plant species. To obtain strong, disease-free plant varieties for use as breeding plants for farmers in the project. and people interested in commercial use Bringing benefits to the Thai agricultural industry
Doi Kham Research Team Began studying SLRSV and SCV virus samples from 2018 – 2021 because the virus affected farmers in the area of Royal Factory No. 1 (Fang), Chiang Mai Province, causing a high amount of strawberry production. and the quality of the produce decreased. In 2021, farmers in the company’s promotion system Produced only 27.23 tons of fresh strawberries per 45 rai planted area, decreased from 2018 to 13.98 tons (41.21 tons per 45 rai planted area).
From the detection of viruses in strawberry plants 80 royal varieties from farmers’ plots at Ban Nong Tao and Ban Khop Dong, Mon Pin Subdistrict, and Ban Mae Ngon Khilek, Mae Ngon Subdistrict, Fang District, Chiang Mai Province, a total of 175 samples using RT – PCR techniques and nucleotide sequence analysis. Confirm destruction It is caused by two types of viruses: strawberry latent ringspot virus (SLRSV) and strawberry crinkle virus (SCV). Most of the leaf samples showed no symptoms of the disease. and found joint destruction of both viruses in leaf samples showing disease symptoms. This research indicates that This method of virus detection is highly accurate and suitable for random testing of viruses in strawberries grown in large areas. To prevent the spread of disease Reduce damage in quantity and the quality of the royal strawberry variety 80
This discovery Bringing benefits to strawberry farmers To be able to select disease-free plant stems from plant stem screening at the Plant Research Laboratory (LAB), creating standards to raise the quality of produce. and the quantity per rai increased according to Doi Kham standards as well.
By this research accepted and published in agricultural journals Academic Journal of the Faculty of Agriculture Chiang Mai University, 40th edition (Issue 1), January – April 2024, topic: “Detection of the virus causing leaf spot disease. and wrinkled leaves in royal strawberries 80 plants grown in Fang District, Chiang Mai Province.” This journal has been accepted by the Thai Journal Citation Index Center (TCI) at level 1, considered acceptable by academics in Thailand and ASEAN.
