Control methods of common diseases and insect pests of Zizania caduciflora

Zizania caduciflora is not only a high bamboo shoot, but also a common vegetable on our table. The yield per mu of Zizania caduciflora is much higher than that of ordinary vegetables. When it grows well, it generally produces about 1500kg per mu. However, a lot of diseases and insect pests will occur in the planting process, when the diseases and insect pests are serious, it will reduce its yield, reduce its quality, and even lose its harvest, so how to control the diseases and insect pests of Zizania caduciflora, the following pro-agricultural network brings common pest control methods.

1. Rust

Rust, also known as plague, mainly harms the leaves and stems of Zizania caduciflora, all occur in the summer high temperature season, serious cases will cause the whole Zizania caduciflora wilt to death. Yellow spots appeared in the leaves at the initial stage of the disease, and finally the whole plant withered and yellowed with the development of the disease, which spread to the stem and affected the yield.

Control methods: reasonable close planting, controlling plant row spacing, strengthening field permeability management, stripping withered leaves and yellow leaves, cooling in irrigation, properly applying some potash fertilizer to improve disease resistance, and then spraying with Baumedu stone sulfur mixture after dilution.

2. Sheath blight

Sheath blight occurs in the environment of excessive application of nitrogen fertilizer and dense growth, and the prevalence rate is higher and the disease is more serious in the environment of high temperature and humidity. At the initial stage of the disease, waterlogged disease spots appeared on the leaf sheath, which gradually spread into moire, and the leaves withered, which is the origin of its name.

Prevention and control methods: scientific and rational fertilization, not partial application, control of growth density and humidity, timely removal of diseased leaves or diseased plants at the initial stage of the disease, and then spray with Jinggangmycin aqueous solution powder.

3. Leaf spot

Leaf spot disease mainly occurs in the environment with poor permeability, when the disease occurs, the leaves appear prismatic spots, and with time the leaves gradually wither and yellow, which affects the yield and quality of Zizania latifolia.

Control methods: strengthen the permeability management in the field, apply potash fertilizer, improve disease resistance, remove diseased leaves at the initial stage of the disease, and then spray carbendazim to prevent and cure the disease. If the disease is more serious, it can be cured by spraying every other week for 3-4 times in a row.

4. Aphids

Aphids are mainly harmful to the leaves. When attached to the leaves, aphids often leave small spots on the leaves, which will seriously lead to hollow or broken leaves.

Control methods: remove weeds near Zizania caduciflora, remove old leaves, reduce the number of aphid eggs, peel off old leaves during the peak period of aphids, and then spray professional insecticide once a week, which can have a control effect.

The above are the common pest control methods of Zizania caduciflora brought by the pro-agricultural network. We can see from the above that most of the diseases are related to permeability, so in order to reduce the occurrence of diseases, we need reasonable close planting and strengthen field management.
