There is a knack for preventing strawberry deformities
1. The flowering period of strawberries cultivated in protected areas is early, and there are few early flower-visiting insects, so bees can be reared in the shed when the first batch of buds are formed. 2-3 boxes of bees are kept in each standard shed, and the beehives are evenly placed around the shed. The pollination rate can be more than 95%, and the bee release time is 8: 00 a.m. and 3: 04 p.m.

Harmful symptoms: Botrytis cinerea can occur at any time from flowering to fruit development. Most of the disease starts from the flowering stage, and the pathogen initially infects the failed flowers or weaker parts, causing the flowers to show light brown necrosis and rot, resulting in a gray mildew layer. Most of the leaves invade from the old yellow leaves at the base, forming V-shaped yellow-brown spots, or from the petals.
