Bactericidal composition containing ningnanmycin and sugar alcohol zinc and application thereof

The invention relates to a composition containing ningnanmycin and sugar alcohol zinc, which comprises the following components in parts by weight: 1-10 parts of ningnanmycin, 5-30 parts of sugar alcohol and 1-10 parts of zinc. The sugar alcohol zinc is wide in source, low in cost and beneficial to plant absorption and can increase the photosynthetic efficiency of crops, promote plant development, improve the stress resistance of plants, increase the yield and improve the quality, and a synergistic effect is achieved after ningnanmycin is added. The composition of ningnanmycin and sugar alcohol zinc is innovatively applied to a dispersible oil suspending agent containing the composition of ningnanmycin and sugar alcohol zinc, a chitin-protein bio-based material is selected as a carrier, the biodegradability is good, and a three-dimensional space colloid structure can be effectively formed, so that the effective components of the raw medicine are highly dissolved and released, and the bactericidal composition
