Diseases and Pests of Primrose and Their Control

Pests and diseases that need to be controlled for four-season primrose (classification error)

The main pests that need to be prevented and controlled for four-season primrose are leaf miners and aphids, and the diseases include stem rot, viral disease, gray mold, etc.

The main damage caused by leaf miners to primrose is the leaves. Leaf miners will eat the flesh of the primrose leaves, reducing the ornamental value of the leaves.

Aphids cause the leaves of primrose to shrink and curl, which also affects its ornamental value. At the same time, aphid pests spread viral diseases. Stem rot occurs mainly on the petioles close to the mechanism. If the temperature is not properly controlled, gray mold will occur, which is a common disease in winter and early spring.

Methods for controlling diseases and pests of four-season primrose

When caring for four-season primrose, you should pay attention to preventing leaf miners. In the early stage of leaf miner infestation, 1000 times of miner can be sprayed for prevention and control. You can use a 1000-fold diluted version to control aphids, with significant results. Viral diseases are mainly caused by aphids, so preventing aphid infestations can avoid the occurrence of viral diseases. Spray 1000 times diluted 50% mancozeb to prevent the occurrence of stem rot and also prevent the spread of stem rot. Gray mold can be controlled with 1000 times the concentration of Sukollect, Gray Mold or Sukollect.

While preventing and controlling diseases and pests, we must strengthen plant management and enhance the plant's disease resistance. Ensure ventilation, reduce air humidity, and control the occurrence and spread of diseases. As long as you take good care of the plants, the chances of disease and insect pests can be reduced.
