Campanula pests and diseases and control methods

Campanula Pests: Aphids

Aphids usually gather on young buds, leaves and branches to suck sap, causing the affected parts of the plants to shrink and deform. Aphids' excrement is on the leaves and may also induce sooty mold disease. Aphids can be said to be the enemy of every kind of flower. If the environment is slightly unsuitable, aphids can easily take advantage of the opportunity.

When a small number of aphids appear on the leaves of bellflowers, it is recommended to wipe the insects off with a rag dipped in soapy water, or rinse them off with a gentle stream of water. When there are many aphids, spray the pesticide once a week for 2 to 3 times in a row. It is especially effective against scale insects and aphids.

Campanula Pests: Red Spider Mites

Red spider mites usually gather on the back of leaves and are difficult to detect without careful observation. They suck sap from the back of leaves, often causing the leaves to discolor or even bend. By the time you discover red spider mites, the leaves have already turned yellow and wilted. More leaves wilt, and flowering will also be affected, because the photosynthesis of the plant is weakened, the accumulated nutrients are reduced, the flowers become dull in color, and slowly wither.

You can use 40% trichloronate diluted with 1000 times water for spraying.

Campanula Pests: Thrips

Adults or nymphs parasitize plants and feed on young shoots, tender leaves, flowers and young fruits. The affected plants grow slowly, their young leaves bend after being eaten, and their buds and flowers wilt.

In the early stage of the disease, 25% dermatophylline emulsion or 40% dimethoate 800-1000 times diluted can be used. Use it once a week for 3 to 4 times in a row, and the effect is significant.
