ISOLATING NEMATOPHAGOUS FUNGI FOR THE PURPOSE OF CONTROLLING NEMATODES PARASITE ON CITRUS
Main Article Content
Abstract
Citrus is one of the main crops in the Mekong Delta. However, yellow leaf and root rot disease are causing serious harm, reducing the vitality of the tree, yield, and fruit quality. The disease is mainly caused by Tylenchulus semipenetrans causing damage to the roots, allowing Fusarium sp to grow and cause root rot. Therefore, the study was carried out to isolate and select several strains of microorganisms be capable of controlling T. semipenetrans well on citrus. The study isolated 1 strain of Arthrobotrys sp., 2 strains of Paecilomyces, and 11 strains of Trichoderma sp. Arthrobotrys sp., was able to reduce nematodes by 72.82% after 15 days of the experiment, strain Paecilomyces NT11 could parasitize strongly on eggs reached 90.67%, and Trichoderma NM22 was able to inhibit the hatching of eggs reached 80.33%.
