How do you test for Verticillium wilt?

How to identify Verticillium wilt

Yellowing, dying, or shrivelling leaves, starting on the older growth.
Dieback of branches.
Stunted or distorted growth, which causes reduced yield on fruit crops.
Sudden wilting in hot weather, sometimes followed by recovery when conditions turn cool and wet.

Does Verticillium wilt spread to other plants?

It invades susceptible plants through their roots and spreads through the plant's vascular system. The list of plants affected by verticillium wilt is extensive and includes trees, shrubs, garden annuals, and perennials. It can also affect fruit and vegetable crops.

How do you fix wilt fungus?

Many important Fusarium wilt diseases are spread in this manner.

Treat seed with a fungicide or heat to destroy the fungus on the seed and to protect the emerging seedlings from infection.
Dip bulbs and corms in fungicide or hot water (or both) to reduce Fusarium.

Can plants recover from wilt?

Interestingly, wilting also serves to reduce water loss, as the drooping leaves expose less surface area to the sun's evaporative rays. Most plants recover quickly when given water, though prolonged dehydration can be fatal or cause leaf death.
