Detailed Guide to Common Pest and Disease Control Methods for Goji Berry

Goji berry is a health-promoting and nourishing food. In daily life, many people often use it to make tea, as it has benefits such as nourishing the liver, tonifying the kidneys, and moistening the lungs. In addition, it also has excellent ornamental value. During goji berry cultivation, it can suffer from various pests and diseases, which seriously affect the yield and quality of goji berries. Below is an introduction to the symptoms and control methods of common goji berry pests and diseases.

1. Goji Berry Anthracnose

Goji berry anthracnose mainly damages the fruit, but can also affect leaves and flowers. Because it causes the fruit to turn from red to black after infection, it is also called black fruit disease. It is a fungal disease and is also a major disease in the goji berry cultivation process. This disease can occur throughout the entire growth stage of goji berry, and is more harmful during rainy seasons, spreading relatively quickly. When the disease occurs, small brown spots appear on the fruit, which then spread into irregular lesions. As the disease progresses, the lesions begin to sink and soften, turning black. In dry periods, the entire fruit shrivels, while during the rainy season or periods of high humidity, orange-red spore masses appear on the fruit surface, and it can also affect leaves, causing the same symptoms to appear on the leaves.

Control methods: Strengthen field management. In winter, prune diseased branches and leaves, then collect fallen debris from the ground, burn it in a centralized manner or bury it deeply. Then spray Bordeaux mixture during rainy periods for prevention. When the disease occurs, alternate spraying with mancozeb and thiophanate-methyl for control.

2. Goji Berry Gray Leaf Spot

Goji berry gray leaf spot is also a fungal disease, but it mainly damages leaves and can also affect fruit. When the disease occurs, round lesions appear on the leaves. The central area of the lesion is grayish-white or brown, with a darker edge, and the affected area is sunken. As the disease progresses, the lesions begin to turn brown and dry up, and finally black mold-like substances appear.

Control methods: Similarly, strengthen field management. The prevention methods are the same as for anthracnose. When the disease occurs, spray 50% carbendazim wettable powder at 500 times dilution, once every half month, for 2-4 consecutive applications to treat it.

3. Goji Berry Powdery Mildew

Goji berry powdery mildew is also one of the fungal diseases. It mainly damages leaves and can also affect fruit in the early growth stage. It is named because the leaves become covered with a white powdery mold layer when the disease occurs. When the disease occurs, the leaves begin to lose green color, wrinkle, and curl. As the disease progresses, the leaves eventually turn yellow and fall off.

Control methods: The prevention methods are the same as the previous two, which are cleaning the orchard and spraying Bordeaux mixture. When the disease occurs, spray 25% triadimefon at 800 times dilution and 50% carbendazim at 500 times dilution, also once every half month, for 2-3 consecutive applications.

4. Pests

Goji berry has many pests during growth, mainly including goji berry gall mite, goji berry aphid, goji berry leaf beetle, goji berry leaf beetle, and goji berry stink bug. They mainly damage tender parts such as leaves, young shoots, flower buds, petals, and young fruit. Their harmful methods are also chewing fleshy tissues or sucking sap, causing plant growth to be hindered, growth to slow down, tree vigor to weaken, and ultimately affecting yield and quality.

Control methods: They mainly cause damage as larvae, so a combination of agricultural and chemical control methods can be adopted. In winter, be sure to clean up weeds and debris in the field, and combine watering and loosening the soil to destroy their overwintering environment and reduce pest sources. During pest outbreaks, spray pesticides for control.
