Please use these guidelines for submitting a sample.
-
Samples should be fresh.
-
Samples should represent the early to middle stages of the problem. A completely dead and decaying sample cannot be reliably diagnosed.
-
Samples should be carefully packaged and shipped early in the week to avoid weekend layovers during which the sample will deteriorate.
-
Be sure to include sample documentation and background information. The specimen form can be downloaded from: General Form
-
Pictures of the problem in the field are always helpful. The environmental conditions of the plant can play an important role in the diagnosis.
