Phát triển và xác nhận phương pháp nhiễm bệnh để đánh giá hiệu quả của các biện pháp điều trị sinh học chống lại bệnh héo Verticillium ở cây olive
Tóm tắt
Bệnh héo Verticillium ở cây olive, do nấm đất Verticillium dahliae gây ra, là một trong những bệnh nghiêm trọng nhất của loại cây này do tỷ lệ chết cây cao và sự khó khăn trong việc kiểm soát. Một trong những rào cản lớn trong việc phát triển các biện pháp kiểm soát bệnh này là thiếu các phương pháp nhiễm bệnh để đánh giá hiệu quả của các liệu pháp điều trị. Trong nghiên cứu này, chúng tôi đã so sánh năm phương pháp nhiễm bệnh để sàng lọc các tác nhân kiểm soát sinh học (BCAs). Đất nhiễm bệnh với môi trường cát bột ngô ở nồng độ 20% w/w đã cho kết quả tốt nhất, và hiệu quả của nó được kiểm tra thêm trên các cây olive được điều trị bằng sáu BCAs, bốn chủng của các loài nấm Fusarium moniliforme, F. oxysporum, Gliocladium roseum và Phoma sp., cùng với hai hỗn hợp lên men của nhiều loại nấm men và vi khuẩn. Các chủng F. oxysporum, Phoma sp. và hai hỗn hợp vi sinh vật đã giảm đáng kể độ nghiêm trọng của bệnh trên cây olive cv. Picual trong chậu.
