Diseases of the lucky tree and their prevention and treatment

Leaf spot disease of lucky tree

The lucky tree will develop leaf spot disease when it is exposed to high temperature and high humidity.

Leaf spot disease can cause the lucky tree to have symptoms such as yellowing leaves, spots on the leaves, and dry branches.

Prevention and control methods: When the lucky tree gets leaf spot disease, the first thing to do is to increase ventilation and light to evaporate the moisture on the leaves, because high temperature and high humidity will cause water accumulation and cause the leaves to rot and turn yellow, thus causing leaf spot disease.

Secondly, if infected leaves are found, they should be removed in time and then sprayed with 600 times diluted 50% carbendazim wettable powder. Such spraying should be done once every half a month, and sprayed three times each time.

Finally, if you have a potted lucky tree, you need to apply Daknin cream ointment.

The symptoms of the disease are small white spots on the leaves, which will be covered with a white powdery mold layer. After the flowers are infected, white powdery mist will appear on the buds, affecting the ornamental value of the lucky tree and making the plant short and lifeless.

The disease is usually most severe in June, but can also occur in September.

Prevention and control methods: For the powdery mildew of the lucky tree, soak it in green onion liquid with water for half a day to extract the juice, then spray it on the leaves. Spray it about 3 times a day for 4 days to see the situation. Stop spraying when it is basically cured, and continue spraying if it is not good.

Or use rice vinegar: add rice vinegar to water and spray it on the leaves, spray once every 7 days, and spray 3 or 4 times continuously.

Sooty disease of the lucky tree

The sooty mold disease of the lucky tree is also a fungal virus. The disease occurs in summer and autumn, and it mainly harms the leaves and branches of the plant.
