Effect of sugarcane white stripe disease: introduction to sugarcane white stripe disease and its control methods

Do you like sugar cane? If you want to know about the diseases and insect pests of sugarcane, here is an introduction to white stripe, one of the diseases of sugarcane. This paper mainly introduces the symptoms, ecology and control methods of white stripe disease. Let's take a look.

Symptoms: there are chronic and acute types of the disease.

(1) chronic type: the symptoms change greatly. It is a typical symptom that the leaves produce white stripes of 1 mm and 2 mm, such as pencil lines. Sometimes the leaves turn white. Discolored tissue occasionally has gangrenous erythema. The diseased plant is easy to produce lateral buds, and the leaves of lateral buds also show the same symptoms.

(2) Acute type: the whole plant or part of the tiller suddenly showed leaf curling and withering, just like cutting off the root system inadvertently. When these damaged stems tillered again, they all showed the same symptoms of chronic type.

Disease ecology: in addition to the transmission of sugarcane seedlings, the field can be infected with diseased cane juice through a cane knife when cutting sugarcane. The diseased and healthy plants were adjacent to each other, and the phenomenon of disease transmission also occurred. The disease in the field began to occur in large quantities from November to December.

Prevention and control methods:

First, plant disease-resistant varieties F160, ROC12 and so on.

Second, serious farms should collect seedlings from disease-free areas and carry out sugarcane seedling renewal.

Third, the infected sugarcane orchard should not have persistent roots, and the diseased plants should be removed and burned.

4. The cutting tool of seedling harvester or harvester should be sterilized with 10%Iodophor when changing different area numbers of sugarcane orchards.

Pay attention to the diseased plants in the nursery period. If diseased plants are found, they should be removed immediately. The incidence rate is more than 5%, and seedlings shall not be collected.

Now you know how to control the white streak of sugarcane, mainly from five aspects.
