Rice, corn, beans, cabbage and sugarcane are found to be resistant to bacterial wilt.
Bacterial wilt is a serious disease caused by Erwinia tracheiphila. It can severely affect cantaloupe, muskmelon, and cucumbers, and, less severely, summer squash and pumpkin. Watermelon is resistant to this disease.
Bacterial wilt is one of the major diseases of tomato and other. The family includes the Datura or Jimson weed, eggplant, mandrake, deadly nightshade or belladonna, capsicum, potato, tobacco, tomato, and petuniasolanaceous plants.
Plant cultivars of vegetables with resistance to Fusarium and Verticillium wilts. Cantaloupes, peas, and tomatoes have a wide selection of resistant varieties whereas other crops have limitations (Table 3).
Grow 'County Fair', a cucumber cultivar with genetic resistance to bacterial wilt.
Bacterial wilt (Erwinia tracheiphila) is a serious disease of melons. Watermelons are resistant to this disease. Bacterial wilt is transmitted by spotted and striped cucumber beetles that feed on melon foliage. Infected plants exhibit leaf wilting followed by vine collapse (Figure 18).
There are now Fusarium resistant sweet basil cultivars available such as Aroma-2, Prospera and Obsession as well as others. If Fusarium wilt is introduced into the field growers should not grow any sweet basil or members of the mint family in that field for at least 2-3 years.
Avoid over-watering: Over-watering can increase the chances of Fusarium Wilt because the fungus thrives in moist soil.
Avoid pruning or handling plants when they are wet: Bacteria can spread more easily when plants are wet. Keep the soil moist: Do not overwater, but keep the soil consistently moist to avoid stressing the plants.
Tomato is the solanaceous crop most frequently affected by a Fusarium wilt disease in Kentucky, but Fusarium wilts can also occur on eggplant and pepper. Affected cucurbit crops include cucumber, watermelon, and occasionally muskmelon.
Some tomato varieties are resistant (Saturn, Venus, Neptune, Tropic Bay, and Kewalo). To test for Southern Bacterial Wilt in tomatoes, cut a piece of stem from near ground level and put it in a jar of water.
Bacterial wilt, also known as brown rot of potato, is caused by the group of soilborne bacteria in the Ralstonia solanacearum species complex. It is an economically significant disease of solanaceous vegetables, such as potato and tomato.
Bacterial wilt of tomato is a top-down wilt as opposed to fusarium and verticillium where symptoms begin at the bottom of the plant. These wilt diseases are all soil-borne and can persist for many years in the soil even if no host plants are grown. They can also be brought into a garden on infected transplants or soil.
Symptoms and Signs
Initially, symptoms of Fusarium wilt of tomato appear as one-sided wilting of only half of the plant, branch, or leaflet. At first, the plant will appear to recover from the wilt, but as the disease progresses, it will become permanent regardless of temperature or water status.
Resistant plants
Monocotyledonous plants (e.g. grasses, members of the iris family and most bulbs) are generally resistant. Conifers are immune to the disease.
Fusarium wilt has been a major problem in California blackeyes production. Fusarium wilt is less of a major problem for common beans. For garbanzo beans, Fusarium wilt has been more widespread on the coast than in the Central Valley.
The disease is favored by cool soil and air temperatures. Verticillium wilt is difficult to distinguish from Fusarium wilt and positive identification may require cultivating the fungus in a laboratory. Verticillium wilt seldom kills tomato plants but reduces their vigor and yield.
You can often get rid of the verticillium wilt fungus in the soil by solarization. Soil solarization heats up the top 6 inches (15 cm.) or so of soil to temperatures high enough to kill the fungus. Prepare the soil by tilling or digging and then wetting it down.
Verticillium wilt can affect all cucurbits.
Some varieties are not resistant to the beetles, but are resistant to the bacterial wilt disease transmitted by the beetles. Chinese Long and Tokio Long Green cucumbers are resistant to wilt, as are Buttercup squash and Black Beauty zucchini. Connecticut Yellow Field pumpkins are also resistant.
You may want to experiment with different companion crops until you find the perfect combination to fit your personal tastes and growing conditions. Avoid planting zucchini and summer squash with all other vining plants which include cucumbers and sweet potatoes as well as pumpkins, winter squashes, and melons.
Diseases, viruses and insects are all challenges when growing pumpkins, according to UGA Cooperative Extension horticulturists. The “Orange Bulldog” variety gives gardeners “a leg up,” since it can be grown without pesticides while still resisting powdery mildew, viruses and insects such as vine borers.
