How do you control pests and diseases on goji berry trees? Are there any knowledgeable readers who can help explain?Zhongdi Network has compiled pest and disease control methods for goji berry trees, listed below for readers' reference.
1. The harm and control methods of black fruit disease in goji berry trees:
Goji black fruit disease generally occurs from May to August, harming green fruit, flower buds and flowers. After infection, brown lesions appear on the fruit.
Control methods: Dig trenches for drainage and remove diseased fruit. During the fruiting period, spray with 1:1:100 Bordeaux mixture, and immediately after rain spray 50% Tuzet wettable powder at 600 times dilution.
2. The harm and control methods of root rot in goji berry trees:
Root rot generally occurs in late June and is more severe in July and August. In the early stage the roots turn black and gradually rot, after which the above-ground parts wither and the whole plant dies.
Control methods: Drench the roots with 50% Thiophanate-methyl at 1000-1500 times dilution or 50% Carbendazim at 1000-1500 times dilution.
3. The harm and control methods of fruit flies in goji berry trees:
Fruit flies mainly harm young fruit, with 2-3 generations per year, and their pupae overwinter in the soil.
Control methods: Use 80% Dichlorvos emulsifiable concentrate at 1000 times dilution or 40% Dimethoate emulsifiable concentrate at 1500 times dilution, spraying once every 7-10 days for 3-4 consecutive sprays. You can also use poisoned soil to kill newly emerged adults in the soil or manually remove maggot-infested fruit.
4. The harm and control methods of aphids in goji berry trees:
Aphids mainly harm young buds, leaves and young fruit. Multiple generations occur per year. The damage is most severe from late May to mid-July.
Control methods: 40% Dimethoate emulsion at 2000 times dilution, spraying once every 7-10 days for 3 consecutive sprays.
5. The harm and control methods of gall disease in goji berry trees:
Gall disease is mainly caused by gall mites, whose adults begin laying eggs in mid-to-late April, after which the larvae invade the tissues, causing the tissues to become deformed and turn into blue-black mole-like galls. The new shoots are harmed the following year.
Control methods: In the early stage of occurrence, spray with 40% Dimethoate emulsion at 1500-2000 times dilution.
6. The harm and control methods of the goji berry leaf beetle:
The adults and larvae of the leaf beetle harm young leaves, and in severe cases can completely consume the leaves. There are 3 generations per year, with the most severe damage in June and July.
Control methods: From July to August, use 40% Dimethoate emulsifiable concentrate at 1500-2000 times dilution or 80% Dichlorvos emulsifiable concentrate at 1500 times dilution, spraying once every 7-10 days for 3-5 consecutive sprays.
