Growers inevitably encounter some diseases and pests during the cultivation of orange trees. Leaf curl disease is very common in orange trees. Diseases, pests, excessive sun exposure, and fertilizer damage can all cause leaf curling in orange trees. Generally, when this phenomenon occurs, it is likely to be infected with leaf curl disease. Let's introduce the prevention and treatment of orange tree leaf curl from three aspects: causes, treatment methods, and preventive measures.
1. Causes
Leaf curl disease is a disease transmitted by pathogens. When the soil contains pathogens, it can affect the growth of orange trees, leading to leaf curling.
2. Treatment Methods
When orange trees are infected with leaf curl disease, it is necessary to handle it promptly by cutting off the diseased leaves and branches and disposing of them collectively to stop the spread of the disease. After pruning, you can spray an appropriate amount of carbendazim or thiophanate-methyl on the orange trees for treatment. However, it is important to note the frequency of using pesticides. Generally, you can spray once every 7-10 days, and after 4-6 consecutive sprays, the leaf curl disease in orange trees can be properly mitigated. At this time, the orange trees will be in the recovery period, and it is necessary to enhance ventilation within the orchard to maintain air circulation, which is beneficial for the recovery of the orange trees.
3. Preventive Measures
Before planting orange trees, it is recommended to choose quality seeds with strong resistance to diseases or viruses, or rootstocks with virus resistance, which can prevent orange trees from being infected with leaf curl disease from the root. During the maintenance period, attention should be paid to various factors affecting the growth of orange trees, such as temperature and humidity, because unsuitable environments or improper care can also cause leaf curling in orange trees. In daily care, you can also spray carbendazim or bicontrol fungicides once every 15-30 days to prevent leaf curl disease.
