Đánh giá về tình hình bệnh Panama (Fusarium oxysporum f. sp. cubense - Foc) trên cây chuối già Nam Mỹ canh tác tại Khu liên hợp nông nghiệp Snuol (Campuchia) và biện pháp quản lý

Abstract

Panama disease is a fairly serious pest on Cavendish Bananas at the Cambodia Snuol Agricultural Complex of THAGRICO Corporation - a member of THACO Vietnam Group. From 2020 to mid-2021, 183,311 banana plants were destroyed by the disease, equivalent to about 85 hectares of bananas lost, and the damage rate accounted for 3.25% of the total area with 2,557 hectares of banana plants in Snuol Agricultural Complex. The most optimum method for disease control is isolating the areas of banana plants being infected with Panama disease. Then, the following steps are cutting stems and leaves, raising seedlings between two rows of bananas, injecting Glyphosate or Glufosinate into the stems of banana plants, spreading lime, and spraying fungicides on the area of banana plants being infected with the disease within a radius of 10 metres. After spraying fungicides seven days, spraying Trichoderma sp. is conducted on the isolation area.
