| 摘要 |
The invention includes a new, cold tolerant strain of mycoparasite Trichoder ma and mutants that are resistant to a pesti- cide to which the Trichoderma isolate is sensitive. These novel Trichoderma are capable of parasitizing fungi which are pathogen- ic to plants. They are also capable of producing proteinaceous, antimycotic substances which can inhibit the growth of plant pa- thogenic fungi. Cold tolerant Trichoderma and its biotypes can be used in, b ut not limited to, controlling fungal plant disease, This invention still further relates to a method of promoting the growth and development of a plant by applying an agriculturally effective amount of the Trichoderma isolate or Benomyl resistant mutants of the Trichoderma isolate to a plant or plant tissue.
