The invention provides a
Trichoderma asperellum TAZ19, a biocontrol inoculant and application of the
Trichoderma asperellum TAZ19, the
Trichoderma asperellum TAZ19 is preserved in the China Center for Type Culture Collection on October 25, 2024, and the preservation number of the
Trichoderma asperellum TAZ19 is CCTCC M 20242341. The active ingredients of the biocontrol inoculant comprise the
trichoderma asperellum TAZ19 strain, and the
trichoderma asperellum TAZ19 strain is one or more of conidia,
hypha,
fermentation filtrate or active extracts of the
trichoderma asperellum TAZ19 strain of the
trichoderma asperellum TAZ19 strain. The
trichoderma asperellum TAZ19 has an excellent antagonistic effect on a plurality of
plant disease pathogenic bacteria such as dispora pinnatifida, a plurality of
fusarium oxysporum, apple black beancurd
skin fungi and
botryosphaeria dothidea, has broad-spectrum
antibacterial activity, is high in
growth speed, high in
antibacterial activity and high in hyperparasitism ability, has better
saline-alkaline tolerance, also has a
growth promoting effect on plants, and can be widely applied to the field of
plant diseases. The strain can be used as an
active component of a biocontrol inoculant to be widely applied to prevention and treatment of various
plant diseases such as
pine tree branch rot, wheat
stem rot and tomato
fusarium wilt, and has a wide application prospect.
