Control methods of diseases and insect pests in wampee

Yellow skin, also known as yellow marbles, yellow section, originated in southern China, is a set of edible, medicinal and greening as one of the fruit trees. In production, diseases and insect pests will endanger the quality and yield of fruits, so in order to obtain high yield and high quality, we must pay attention to the prevention and control of diseases and insect pests.

1. Anthrax

Anthracnose develops throughout the growth period of wampee, which mainly harms leaves, branches and fruits. Brown fertilizer appears at the tip and edge of leaves after the disease occurs. Within a week, the leaves will die, the petiole will turn brown, and the leaves will fall off early leading to bald branches. Branches can also lead to branch withering or branch rot after infection.

Control methods: strengthen the fertilizer and water management in the garden, increase the application of organic fertilizer and phosphorus and potassium fertilizer, enhance the tree potential and disease resistance, clean up the diseased branches and leaves in time, reduce the source of disease, and spray carbendazim and Bordeaux solution.

2. Soot disease

It mainly harms leaves and fruits, mostly induced by aphids and scale insects, leaves and branches will slightly produce brown mildew spots, with the development of the disease, black mold covers the whole leaf surface, like a layer of coal soot, the leaves curl and wither, and after the disease occurs, the surface will also be covered with a layer of black mold, reducing commerciality and affecting quality.

Control methods: do a good job in the control of aphids and scale insects, select varieties with strong disease resistance, and spray low concentration lime Bordeaux solution to control the disease.

3. Leaf spot

The main harm to the leaves, the leaves appear white round or irregular disease spots, the edge of the disease spot is brown or reddish brown, some multiple disease spots or fusion together to form large disease spots.

Prevention and control methods: timely removal of diseased leaves, reduce the source of bacteria, and then spray carbendazim, isocarbamide control, the effect is better.

4. Aphids

Aphids harm to adults and larvae, they will gather in the young parts of the plant, such as tender leaves, shoots and young fruits, sucking juice, resulting in the destruction of plant growth nodes, resulting in poor plant growth, affecting yield and quality.

Control method: it is a long-term work for the control of aphids. Imidacloprid or other insecticides are sprayed every 7-10 days during the period of aphid damage.
