Abstract
The invention discloses a fruit disease antiseptic preservative agent, composed of cryptococcus laurentii suspension, pyrimethanil and water. Every 1L preservative agent contains 1*10<10>-1*10<11> cryptococcus laurentii cells, 4-400mg of pyrimethanil, and the balance of water. Preservation name of cryptococcus laurentii is Cryptococcus laurentii ZJU 10, preservation organism is China General Microbiological Culture Collection Center, preservation data is January 20, 2010, preservation number is CGMCC NO.3590, and preservation address is No.3, Courtyard 1, Beichen West road, Chaoyang District, Beijing, namely Institute of Microbiology of Chinese Academy of Sciences. The fruit disease antiseptic preservative agent has the characteristic that preservative effect is good.
Description
technical field [0001] The invention relates to the technical field of fruit postharvest disease prevention and control, in particular to a fruit antiseptic and fresh-keeping technology utilizing antagonistic yeast and low-dose bactericide. Background technique [0002] Postharvest diseases of fruits and vegetables are a global problem. In developed countries, about 10%-30% of fresh fruits and vegetables are lost due to rot due to postharvest diseases. For a long time, the main measure to control postharvest diseases of fruits and vegetables is to use fungicides. However, due to the long-term and large-scale use of fungicides, the environment is seriously polluted and it will cause harm to human health. In addition, high-frequency use of a single type of fungicide will lead to the problem of drug resistance of pathogenic bacteria, which will greatly reduce the control effect of fungicides. [0003] Pyrimethanil (pyrimethanil) is a new type of fungicide for plant diseases....
