How are diseases caused in plants? How
can these be prevented?
Answers
Answer:
To protect healthy plants, you can manipulate environmental conditions, remove infected plants, or apply protectant pesticides. Good sanitation practices are especially important to prevent problems, because a single infected seed can result in an entire tray — or even an entire greenhouse — of diseased plants.
Answer:
a) Most plant diseases – around 85 percent – are caused by fungal or fungal-like organisms. However, other serious diseases of food and feed crops are caused by viral and bacterial organisms. Certain nematodes also cause plant disease.
b) Traditional Principles of Plant Disease Control. Avoidance—prevent disease by selecting a time of the year or a site where there is no inoculum or where the environment is not favorable for infection. Exclusion—prevent the introduction of inoculum. Eradication—eliminate, destroy, or inactivate the inoculum.
