what disease comes from plants?...it is a biology question i have to answer.?

Answer 1

Lots of conditions can result from plants. Poison ivy rash is a good example.

I'm not sure that plants cause any diseases, per say, but they can make people sick.

Answer 2

Air, water and soil are the major sources of inoculum. Botrytis spores are present in the air as are Fusarium spores. They come from diseased plant material present in soil. Pythium is present in soil and water. If a dugout not lined with plastic material is used as a water source, a lot of soil particles are suspended in the water. This water can be a major source for Pythium.
There was a time when greenhouse crops were primarily grown in soil and Fusarium wilt was a big problem. Growers would steam pasteurize the soil, but soon found that the disease severity had increased. By monitoring the air, researchers found high numbers of Fusarium spores and these spores could colonize pasteurized greenhouse soil quickly before other organisms can take hold. There has been cases of white mold (Sclerotinia) being brought into the greenhouses by honey bees visiting from the canola fields outside. Fungus gnats can carry the spores of Pythium with them. Several insects are known to carry viruses into the greenhouses.
All our food comes from plants or animals that eat plants so when plants get sick .
