Edible fungi are often endangered by molds such as Trichoderma and Aspergillus. These bacteria not only compete with edible fungi for nourishment and space, but also secrete various toxins to inhibit the growth of edible fungi hyphae and fruit body development, resulting in reduced yield and reduced quality. At present, there are few types of fungicides that can be used in the production of edible fungi. In this regard, the author selected six kinds of biocides, which have good control effects on plant diseases, such as zhongshengmycin and ningnanmycin, and studied the oyster mushrooms and bacteria. The effect of mycelial growth is to screen out fungicides that can effectively control mold contamination without affecting the normal growth and development of edible fungi.

The six biological fungicides tested were 3% zhongshengmycin wettable powder, 8% Ningnanmycin aqueous solution, 5% Jinggangmycin aqueous solution, 6% Chunleimycin wettable powder, and 1.5% polyclonal antibody. Magnesium wettable powder and 4% pyrimidine nucleoside antibiotic. After 1000-fold dilution, the effects of mycelial growth inhibition rate on the growth of Trichoderma, Aspergillus, Aspergillus niger and Pleurotus ostreatus were determined.
The test data showed that the above six biological fungicides have certain inhibitory effects on three kinds of fungi and oyster mushroom hyphae. Among them, zhongshengmycin had the greatest inhibitory effect on the three kinds of mycelium, followed by Ningnanmycin, which had the least inhibitory effect on Pleurotus ostreatus. Tests have shown that neutrophin and ningnanmycin are suitable for use in the production of oyster mushrooms. (Yang Guang)
