In a healthy tree, water in the soil enters roots and is trans- ported through vessels or tracheids in the xylem to leaves. Wilt diseases disrupt this flow of water in the xylem, thus causing leaves to wilt. These diseases result from pathogen activity in the vessels or tracheids.
First the leaves turn yellow and wilt, mostly on one side of the plant. Finally, the whole plant wilts. Other symptoms are brown discolouration of the xylem vessels which can be seen when the stems are cut. In banana, whole plantations may die and the soil may not be suitable for planting for many years to come.
Remove infected crop residues and regularly disinfect tools and machinery to reduce inoculum spread. Pull out diseased plants with their roots and dispose of them away from production fields. For irrigation systems, use chlorination or other approved water treatment methods to prevent Fusarium wilt spread. Plant care.
The same bacteria also cause wilt diseases of potatoes (Solanum tuberosum), tomatoes (Solanum lycopersicum), aubergine (eggplant) (Solanum melongena), banana (Musa species), geranium (Pelargonium species), ginger (Zingiber officinale), tobacco (Nicotiana tabacum), sweet peppers (Capsicum species), olive (Olea europea), ...
Wilting can be caused by drought or waterlogged soil
Plants wilt when roots are unable to supply sufficient moisture to the stems and leaves. Wilting for short periods of time does not harm plants. Sometimes a plant wilts on a hot day because moisture is evaporating from the leaves faster than the roots can take it up.
Wilt diseases disrupt this flow of water in the xylem, thus causing leaves to wilt. These diseases result from pathogen activity in the vessels or tracheids. Wilt pathogens are parasites that can move through the vascular tissue of trees. The pathogens can include fungi, nematodes, bacteria, or other micro-organisms.
If you have a wilting plant the first thing you want to do is give it a thorough watering. You can accomplish this by putting your plant in the sink, or adding watering for anywhere from 3 to 8 minutes (depending on pot size and specific plant/soil requirements), letting the water completely drain out of the bottom.
Wilting isn't always a sign your plant is unhappy, if you're seeing a few wilted leaves near the bottom of the plant it probably just means they've completed their lifecycle.
If fusarium wilt hits your garden, don't plant the same or related plant types in that area for at least four years. Depending on your climate, it may be possible to control fusarium wilt by "solarizing" your soil. This involves covering it with plastic so it reaches very high temperatures over a long period.
For Fusarium oxysporum f. sp. lactucae, the pathogen which causes Fusarium wilt of lettuce, the required temperature for control is generally taken to be > 140°F for 20 minutes.
Symptoms of verticillium wilt can be confusing because they are so variable. They include marginal scorch and complete wilting of leaves on individual branches in the crowns of potential hosts. Symptoms can occur at any time of the year but often show up when hot, dry weather begins.
Bacterial wilt is caused by the bacterium Ralstonia solanacearum. The bacterium can survive in the soil for several years, even in the absence of a host plant. It infects the plant through its roots and moves up through the vascular system, where it multiplies and blocks the flow of water and nutrients.
Treating fusarium wilt of tomatoes is not possible. Affected branches or entire plants can only be destroyed, as they will die eventually. Prevention is the only way to avoid the damage of fusarium wilt in your tomato garden. Start with varieties that resist the disease.
In general, however, Fusarium wilt diseases are best controlled by using resistant or tolerant cultivars, not by using soil applied fungicides. Liming soils and using nitrate nitrogen fertilizer have been effective for management of F. oxysporum on chrysanthemum, aster, gladiolus, cucumber, tomato, and watermelon.
Avoid over-watering: Over-watering can increase the chances of Fusarium Wilt because the fungus thrives in moist soil.
There is no effective fungicide or other cure for Fusarium wilt. The pathogen nearly always kills infected hosts. Prevention and exclusion are the only effective management strategies. Avoid this problem by replanting at that site using species from different genera than plants previously infected there by Fusarium.
Unfortunately, there is no cure for fusarium wilt. The only option is preventing fusarium in your plants. Once your plants are infected, they must be removed and destroyed.
The significant reduction of fusarium wilt disease in tomato plants treated with neem extract could be due to the presence of gedunin i.e. tetranortriterpenoid which posses antifungal properties (Sadre et al., 1983) or due to presence of Azadirachtin (tetranortriterpenoid).
It's a visual cue that the plant's health is compromised, either due to environmental factors or care practices. However, wilting doesn't always signal the end of a plant's life. With appropriate measures, it's possible to revive wilted flowers, depending on the severity and duration of their condition.

Wilting: Paradoxically, overwatered plants can show signs of wilting. This is because waterlogged soil can lead to a lack of oxygen, preventing the roots from taking up water even if it is plentiful in the soil. The plant may exhibit wilting even though the soil is wet.
synthetic fungicides are widely used to control wilt diseases. Katyayani Coc 50 and Katyayani Samarth are the two best fungicide for control of Fusarium wilt.
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.
