The Pest and Disease Control Methods for Camellia
1. -- Anthracnose --
Anthracnose mainly occurs on the leaves of camellias, initially appearing as small red-brown spots, which later expand into deep-brown lesions. As the spots increase in number and size, severe cases can cause most of the leaves to turn black and die.
Control methods:
剪除 the affected leaves at the initial stage of the disease and burn them promptly to prevent expansion; avoid dense placement and avoid overhead watering, and maintain ventilation and light. Spray 50% carbendazim wettable powder 700-800 times dilution, or 50% carbazole wettable powder 500 times dilution.2. -- Sooty Mold --
Sooty mold can damage the branches and leaves, initially appearing as small sooty mold spots, which later cover the plant with a sooty mold layer. This not only severely affects photosynthesis and respiration but can also cause the plant to shed many leaves.
The Pest and Disease Control Methods for Camellia
Control methods:
We should maintain a well-ventilated and breathable environment for the plant, and the humidity should not be too high. At the initial stage of the disease, spray 50% thiophanate-methyl wettable powder 500 times dilution, once every 7-10 days, for 3 times, which can achieve a therapeutic effect.3. -- Scale Insects --
Scale insects are the most common pests, usually clustering on branches, leaves, and fruits to absorb camellia sap. In severe cases, they can cause branches to wither or the plant to die. In addition, the secretions of scale insects can cause sooty mold, which is very harmful.
