The Latest Methods for Preventing and Controlling Pests and Diseases in Wampee
Wampee, also known as huangdanzi and huangduan, originated in southern China and is a fruit tree that combines food, medicinal and landscaping uses. During production, pests and diseases can harm fruit quality and yield, so to achieve high yield and high quality, the prevention and control of pests and diseases must be taken seriously. Now follow the editor to take a look at the prevention and control methods for common wampee pests and diseases.
1. Anthracnose
Anthracnose develops throughout the entire growth period of wampee, mainly harming leaves, branches and fruit. After the leaves are affected, brown spots appear at the leaf tip and leaf margin, and within one week the leaves wither and die, and the petioles also turn brown. The leaves fall early, causing bare branches, and after branches are infected they may also become withered or rotted.
Prevention and control methods: Strengthen fertilizer and water management in the orchard, apply more organic fertilizer and phosphorus and potassium fertilizer, enhance tree vigor and disease resistance, promptly clean up diseased branches and leaves, reduce sources of infection, and spray carbendazim or Bordeaux mixture for control.
2. Sooty mold
It mainly harms leaves and fruit, and in most cases is induced by aphids, scale insects and the like. When it occurs, small brown mold spots appear on leaves and branch tips. As the disease develops, black mold covers the entire leaf surface like a layer of soot, and the leaves curl and wither. After the fruit is affected, its surface is likewise covered with a layer of black mold, reducing marketability and affecting quality.
Prevention and control methods: Do a good job of preventing and controlling aphids and scale insects, choose varieties with stronger disease resistance, and when the disease occurs, spray low-concentration lime Bordeaux mixture for control.
3. Leaf spot
It mainly harms leaves. When it occurs, white round or irregular lesions appear on the leaves, and the edges of the lesions are brown or reddish brown. Sometimes multiple lesions merge together to form large lesions.
Prevention and control methods: When the disease occurs, promptly remove diseased leaves to reduce the source of the fungus, then spray carbendazim or iprodione for control, which gives a relatively good effect.
4. Aphids
Aphids cause damage as adults and nymphs. They gather on the tender parts of the plant, such as young leaves, young shoots and young fruit, sucking sap, which damages the plant's growing points, causes poor growth, and affects yield and quality.
Prevention and control methods: Controlling aphids is long-term work. During the period when aphids cause damage, spray imidacloprid or other insecticides once every 7-10 days.
