The main pests and diseases in wampee cultivation are as follows:
1. Wampee anthracnose: Wampee anthracnose is a common disease in production, and it can infect the plant at all growth stages, easily causing leaf spots, leaf rot, bare branches, flower rot, and fruit rot. If wampee is intercropped with other crops and planted at high density, while drainage is inadequate and water accumulates after rain, it will affect the yield and quality of wampee. Control methods: Use fertilizer and water scientifically, strengthen tree vigor, pay attention to timely drainage after rain, improve the plant's disease resistance, and prevent pathogen infection. Keep the orchard clean, promptly prune diseased branches and leaves, and dispose of rotten fruit to reduce overwintering sources of the disease. Apply pesticide in a timely manner to protect new shoots and young fruit; pesticide should be applied promptly at the early stage of new shoot sprouting and during the fruit-setting period after flowering. For the pesticide, you may choose 70% thiophanate-methyl wettable powder at 800-1000 times dilution, or 50% Tuzet at 500-600 times dilution, or 75% chlorothalonil at 700-1000 times dilution, or 50% carbendazim wettable powder at 500 times dilution.
2. Wampee sooty mold: It mainly damages leaves, and also damages tender shoots and fruit, causing photosynthesis to be blocked, leading to weakened tree vigor and affecting yield and fruit quality. Control methods: Do a good job of controlling aphids and scale insects to reduce insect sources, strengthen inspection, and apply pesticide promptly in the early stage of the disease. For the pesticide, you may use sulfur colloidal suspension at 300 times dilution, or 40% Miebingwei at 500 times dilution, or 30% copper oxychloride suspension at 600 times dilution.
3. White wax cicada: Prune out infested branches in a timely manner and burn them in a centralized manner. Grasp the early hatching stage of nymphs, and carry out pesticide control before they concentrate and cause damage and disperse. For the pesticide, you may choose 80% dichlorvos at 800 times dilution, or 10% Miebaike at 2000 times dilution, or 40% dimethoate at 1000 times dilution.
