If the primula obconica accidentally suffers from gray mold during the breeding process, it can be sprayed with 1000x mildew at the initial stage. If the Primula obconica suffers from stem rot, it can be sprayed with 50% mancozeb 1000x solution, which can further prevent the spread of the disease.
Grey mold is a common disease of Primula Obconica, which mainly occurs in winter and early spring. Too high and too low temperatures increase the risk of the disease. Once the disease is found, it can be effectively controlled by spraying 1000 times faster.
Stalk rot is also common in the cultivation of Primula Obconica. It mainly occurs on the petiole, and the damage to the plant is relatively large. Once it is found that 50% mancozeb 1000 times liquid can be used to prevent further spread of the bacteria.
