The Latest Control Methods for Common Pests and Diseases of Water Bamboo

Water bamboo is also known as wild rice stem, and it is a common vegetable on our dining tables. The yield per mu of water bamboo far exceeds that of ordinary vegetables; under good growing conditions, it generally yields around 1500 kg per mu. However, many pests and diseases occur during the cultivation process, and when pests and diseases are severe, they can cause reduced yield and lower quality, and in serious cases even total crop failure. So how do you control the pests and diseases of water bamboo? Below, Qinnong Web brings you the common pest and disease control methods for water bamboo.

1. Rust disease

Rust disease, also called blast disease, mainly harms the leaves and stems of water bamboo, and it occurs mostly in the high-temperature summer season. In severe cases, it can cause the entire water bamboo plant to wither and die. In the early stage of the disease, yellow spots appear on the leaves, and as the disease develops, the whole plant eventually turns yellow and withered, spreading to the stems and affecting yield.

Control methods: plant at a reasonable density, control the spacing between plants and rows, and strengthen field ventilation management. When the disease occurs, peel off the withered and yellow leaves, irrigate with water to cool down, appropriately apply some potassium fertilizer to improve disease resistance, and then spray with diluted lime-sulfur mixture at Baume degrees for control.

2. Sheath blight

Sheath blight occurs in environments with excessive nitrogen fertilizer application and dense growth, and the infection rate is higher and the disease more severe in high-temperature and high-humidity environments. In the early stage of the disease, water-soaked lesions appear on the leaf sheaths, gradually spreading and expanding into cloud-like patterns, and the leaves wither; this is also the origin of its name.

Control methods: fertilize scientifically and reasonably, avoid one-sided application, control growth density and humidity. In the early stage of the disease, promptly peel off diseased leaves or pull out diseased plants, and then spray with Jinggangmycin water-soluble powder for control.

3. Leaf spot

Leaf spot mainly occurs in environments with poor ventilation. When the disease occurs, diamond-shaped spots appear on the leaves, and over time the leaves gradually turn yellow and withered, affecting stem formation and leading to reduced yield and lower quality.

Control methods: strengthen field ventilation management, apply potassium fertilizer to improve disease resistance, and in the early stage of the disease also cut off diseased leaves, then spray carbendazim for control. If the disease is relatively severe, spray once every week for control, for 3-4 consecutive times, and it can be cured.

4. Aphids

Aphids mainly harm the leaves, attaching to the leaves and sucking the sap from water bamboo leaves, often leaving small spots on the leaves. In severe cases, they can cause the leaves to become hollow or broken.

Control methods: remove weeds near the water bamboo and pick off old leaves to reduce the number of aphid eggs. During the peak aphid period, peel off the old leaves, then spray professional insecticide for control, spraying once a week, which can achieve a control effect.

The above are the common pest and disease control methods for water bamboo brought to you by Qinnong Web. From the above content, we can see that most diseases are related to ventilation, so to reduce the occurrence of diseases, it is necessary to plant at a reasonable density and strengthen field management.
