真菌除草剂是用以防治目标杂草的具有特定剂型的植物病原真菌制剂,在产品形式和应用技术上亦与化学除草剂类似。真菌除草剂具有二个显著特点:一是经过人工大批量生产而获得大量生物接种体。二是淹没式应用,即在有必要和条件适宜时在田间反复施用,人为地制造目标杂草的病害大流? Fungal herbicides are plant-pathogenic fungal preparations of a specific dosage form that are used to control target weeds and are also similar to chemical herbicides in terms of product form and application techniques. Fungal herbicide has two salient features: First, after a large number of artificial mass production of biological inoculum. Second, submerged application, that is, when necessary and appropriate conditions in the field repeated application, artificially create target weeds disease flow?
