Cauliflower disease is a disease affecting sweet potatoes and other members of the Convolvulaceae family of plants. It is caused by a virus called the Cauliflower mosaic virus (CaMV). The symptoms of the disease include stunting of growth, malformed leaves and flowers, mottled leaves and yellow spots on the leaves.

The most effective way to prevent cauliflower disease is to use clean seed when planting as the virus can be present in the seed. The virus can also be spread from plant to plant, so it is important to keep equipment and tools used for grafting and pruning clean.

One of the best ways to control cauliflower disease is to use plastic mulching. This will help to prevent the virus from entering the crop by reducing the contact the crop has with contaminated soil. Cultivating the soil to a depth of at least 20cm before planting can also help to reduce the occurrence of the disease.

Another way to control the disease is to practice crop rotation. Planting a different crop each year can help to reduce the chances of the virus becoming established in the soil. Introducing pest-resistant varieties of the crop and chemical treatments can also help to control the disease.

It is important to identify and remove infected plants as soon as possible. This can be done by carefully inspecting the plant and removing any leaves or stems that show signs of disease. The affected plants should then be destroyed and the tools used should be disinfected.
