The summer rain gives a refreshing feeling. But for growers, the rains in the first half of the year brought disaster to the second half of the year: a widespread outbreak of oil spot disease from citrus psyllids.
Citrus gets an "uninvited guest" - yellowing of fat spots
Orange spotted macular disease is a special fungal disease that specializes in "bullying" citrus. The disease is mainly leaves and fruits, and in severe cases, it can make the fruit tree "seriously injured".
When plants are damaged, a layer of yellow spots forms on the leaves, which reduces photosynthetic efficiency and nutrient accumulation. Fruits that are "targeted" will grow yellow-brown spots on the skin and become "flower peel fruits", which will affect the appearance.
This disease is most likely to occur in high temperature and high humidity, and should be paid attention to in spring, summer, autumn and winter. Especially in the first half of the month, when there is more rainfall, the risk of outbreaks in July-September increases significantly.
Countermeasures to "fight" against diseases
Therefore, we should not blindly wait for the occurrence of citrus psyllids, but should actively explore an effective way to prevent and control them.
In spring, we should pay attention to the health of the body and apply fungicides in time to prevent lipid spot macular disease.
From May to June, it is necessary to use underground agents in a targeted manner, and from July to September, it is necessary to maintain a high degree of vigilance and continue.
We have a lot of pesticides, such as difenoconazole and benzopyrazole, both of which are powerful "weapons" for the prevention and control of sclerotinia sclerotinia disease.
Strengthening Water and Fertilizer Management: Preparing a "Nutritious Meal" for Fruit Trees
In addition to spray control, fertilizer and water management should also be strengthened. The use of organic water-soluble fertilizer, decomposed bran water or inorganic potassium fulvic acid irrigation can meet the nutrients required for the growth of fruit trees.
With enough nutrients, the fruit tree will become stronger and more resistant. In this case, lipid spot macular disease has the potential to "invade", but with the action of "immunity", these can be avoided.
We can't control the rain in the first half of this year, but we can use scientific methods to "fight" orange peel anthracnose. Let our orange trees thrive without suffering from disease.
