How can I identify and control insects or disease?

Before a problem can be controlled, one must be certain as to the cause. Diagnosis of plant problems is often a very difficult task since there can be many different causes for a given symptom. Even with the necessary laboratory equipment, it is sometimes difficult to determine the exact cause of a plant's problem. Many people bring samples of insects or diseased plants to our office for identification and assistance. If I am unable to determine the cause of the problem, the plant sample can be submitted to a diagnostic library.
