Fleshy Plant Sooty Mold Prevention and Control
Today, our editor will delve into the related topics of the flower clinic, including the popularization and prevention of fleshy plant sooty mold. Next, our editor will introduce the topic to everyone.
Fleshy plant sooty mold can cause the leaves of the plant to gradually wrinkle, develop small black spots, and then dry up and fall off, which is contagious. Gradually, other leaves will also show the same symptoms, and eventually, the whole plant will wither. This is not because there is a problem with our cultivation methods, but because the plant has contracted a disease—sooty mold, which can also lead to plant death.
Sooty mold, also known as soot blight, is one of the common diseases in plants. It primarily affects leaves and petioles, and in severe cases, it can also harm the main stem. When the disease occurs, dark brown mold spots first appear on the leaf surface, which gradually expand, causing the entire leaf or most of the leaf surface to be covered with black sooty material. The sooty layer is easily peeled off, leaving a layer of sooty material on the surface of the pinnate leaves, petioles, and leaf axes, which is the mycelium and fruiting body of the pathogen. Leaves completely covered by soot will turn yellow due to the impact on photosynthesis, eventually leading to the death of the entire plant.
Symptoms of fleshy plant sooty mold: It often occurs on the surface of plant leaves, presenting as brown, gray, or black small mold spots. The cause is not only due to the humid and闷热 conditions in summer, which can lead to infections in the soil and water, but also due to infections carried by various insects. Aphids, scale insects, and ants not only feed on the sap of the plant leaves and roots but also secrete honeydew and excrete feces. These secretions contain various fungi, and after being bitten by these pests, the infection can worsen, leading to the growth of various epiphytic fungi (multiple) pathogens, and then the disease occurs.
In terms of prevention and control methods for fleshy plant sooty mold, in addition to daily maintenance, pest control cannot be ignored. Most pests爆发 in the summer, and since most succulents are dormant during this period, the high temperature and humidity are more conducive to the transmission of fungi and the outbreak of insects. The interaction between pests and pathogens can easily cause your plants to die.
For fleshy plant sooty mold, there are many medications available, and most fungicides are somewhat effective. You can add a certain amount of fungicide to the insecticide, once a week, or spray the fungicide three days after applying the insecticide. Products such as Dithane, carbendazim (above 5% concentration, a high concentration solution can be diluted with more water), Bordeaux mixture, and thiophanate-methyl are also effective.
However, it is very important to note that not all brands of medications containing the above ingredients are effective. It is best to buy from well-known brands or agricultural supply stores for better results.
