Last Updated: 2024/11/22, The production of pollution-free edible roses, the prevention of diseases and insect pests and the maintenance of healthy rose plants is the best way to control diseases. Usually take the following preventive measures: 1. Select disease-resistant strains and use healthy plants as seedlings. 2. Avoid applying too much nitrogen fertilizer, lest the plant will not grow strong enough.

Rose rot usually starts from the root and stem of the flower, which has nothing to do with humidity and temperature, but is damaged by ethylene during storage. The Lignification of the whole stem of rose is the most vulnerable to the gravity of the flower head, so the flower stem is most vulnerable to the production of endogenous ethylene caused by pathogens, and a large number of nutrients are supplied to accelerate ripening and decay after producing a large amount of heat from this blocked pile. Therefore, when roses rot, wine rots and petals often appear at the root and stem of the flower within 1-2 days. The best way to prevent this phenomenon is to carry on the fresh-keeping treatment after the rose harvest, in order to strengthen the fiber Lignification growth at the flower stem and prevent the production of endogenous ethylene, the rose is not treated after harvest, and the florist should also carry out the corresponding fresh-keeping treatment after purchase.
