How to Identify and Treat Diseases of Turnips and RutabagasTurnips and rutabagas are vulnerable to a number of diseases caused by bacteria, fungi, oomycetes, and viruses.
Many of these pathogens affect the leaves of the plants and ruin the ability to eat or sell the greens. Others damage the turnip or rutabaga roots.

Read on to learn about these diseases and how to control them.
Bacterial DiseasesA number of bacterial infections can infect turnips and rutabagas. Starting out with clean seed can help to limit these infections. If you cannot obtain disease-resistant seeds, you can treat them with 122°F water to kill any seed-borne pathogens.
In addition, these bacteria thrive in moist conditions, so avoiding overhead irrigation and not working among the plants while they are wet will help to keep any disease that’s present from spreading throughout the crop.
It is important to purge wild crucifer weeds that can often harbor these diseases – like wild radish and shepherd’s purse – to help keep any destructive bacteria contained and prevent potential spread.
Crop rotation is a critical step, since the bacteria can survive in crop residue in the soil. You should grow other types of plants for at least two years, and up to four years if your plants contract black rot.

If your plants do develop a bacterial infection, spraying with copper hydroxide (Kocide 3000) might help to keep it from spreading further.
