Biopesticide for preventing and treating avocado anthracnose

The invention belongs to the technical field of biopesticides, and particularly relates to a biopesticide for preventing and treating avocado anthracnose. The biopesticide for preventing and treating avocado anthracnose is characterized in that effective components of the biopesticide are formed by compounding trichoderma harzianum, polyoxin, berberine or difenoconazole, and the trichoderma harzianum is a trichoderma harzianum DS-10 parent drug of 20 billion cfu/g. The trichoderma harzianum is compounded with the polyoxin, the berberine or the difenoconazole, the cotoxicity coefficient of the trichoderma harzianum and the polyoxin, the berberine or the difenoconazole is larger than 120, a synergistic effect is achieved, the control effect on the avocado anthracnose can be improved, the use amount of pesticide is reduced, and the control cost is reduced. 本发明属于生物农药技术领域，具体涉及一种防治油梨炭疽病的生物农药。一种防治油梨炭疽病的生物农药，其有效成分由哈茨木霉菌与多抗霉素、小檗碱或苯醚甲环唑复配而成，所述哈茨木霉菌为200亿cfu/g的哈茨木霉菌DS-10母药。本发明哈茨木霉菌与多抗霉素、小檗碱或苯醚甲环唑复配，对油梨炭疽病菌的共毒系数大于120，表现为增
