Control methods of common diseases and insect pests in coconut

We are no stranger to coconuts. Our coconuts are mainly produced in Hainan and Taiwan, where the light intensity and precipitation can meet its growth needs. Coconut is a plant organic fruit, it is not only pollution-free, but also rich in a variety of nutrients beneficial to the human body, but in coconut planting, it will be disturbed by a variety of diseases and insect pests, do you know which? Next, let's take a look at the pro-agriculture network.

1. Grey spot

Gray leaf spot is caused by bacteria infecting leaves, resulting in tissue necrosis of leaves, gradually drying up and curling, weak plant growth, seedlings getting sick, slow growth, affecting the yield of adult trees, passing results, leading to the death of young trees when the disease is serious.

Control methods: strengthen nursery management, improve drainage conditions, pay attention to balanced fertilization, not only nitrogen fertilizer, but also appropriate topdressing of phosphorus and potassium fertilizer, which can improve the disease resistance of the plant. During the onset of the disease, chlorothalonil, Dysengmeng and other agents can be sprayed, and then the infected leaves and fallen dead leaves can be removed, collected and burned, so as to prevent and cure the secondary infection.

2. Bud rot

Bud rot can occur in all stages of coconut growth, sporadic disease, but also a large area of disease, it can be known from its name, it mainly harms the young leaves and leaf buds of coconut trees, with the development of the disease, tender leaves and leaf buds begin to wither and fall off. in serious cases, it leads to leaf bud rot, resulting in bald trunk or death of the plant.

Prevention and control methods: to strengthen management, more inspections, find that leaf buds appear diseases, remove the lesion location in time to prevent the spread of the disease, and then spray copper or other fungicides to prevent and cure the cut, to avoid the invasion of other bacteria and the occurrence of other diseases, in addition, the excised parts must be burned and must not be thrown everywhere, and if the plant grows to be damaged, cut down and burn the whole plant.

3. Diarrhea of coconut stem

Coconut stem diarrhea disease is a common disease in many coconut growing countries. It does great harm to coconut trees. At the initial stage of the disease, there are small disease spots on the stem. With the development of the disease, the disease spots expand and combine into large disease spots. Large and small cracks are formed in the trunk, and the internal tissue of the stem begins to rot, resulting in rust-colored liquid, which in turn leads to the withering of leaves and the death of plants.

Prevention and control methods: coconut protection should be added to prevent trunk loss due to man-made or other reasons, which can reduce the occurrence of the disease, strengthen fertilizer and water management, increase the application of phosphorus and potassium fertilizer, enhance disease resistance and pay attention to drainage. When the disease is found, the lesion site is removed, and then the wound is coated with coal tar or Bordeaux pulp, and the tissue must be burned to avoid secondary infection.

4. Insect pests

There are many insect pests of coconut, but the harm is not much. the common ones are coconut scale, two-wart rhinoceros beetle, red brown weevil and so on. They mainly harm the leaves of coconut trees, suck sap, cause leaves to wither and fall off, affect coconut growth, and in serious cases lead to plant death. leading to plant death is rare.

Prevention and control methods: strengthen management, collect and burn the fallen leaves and branches on the ground in time, prevent pests from laying eggs, and spray insecticides regularly.

The above are the common coconut pest control methods brought by the pro-agricultural network. This is the end of the content about coconut diseases and insect pests. If you want to know more, please pay attention to the pro-agricultural network.
