Help Us Find These Fiendish Foes!
Sample Submission Instructions
Samples will be used for multi-state research of these diseases, and a portion of all samples will be permanently deposited in the U.S. National Fungus Collections in Beltsville, Maryland. It’s a quick and easy way to help scientists combat these destructive plant pathogens.
Step 1: Pack up samples
For Setaria spp. and other small grasses, collect the whole plant, without soil/roots.
For wheat, corn, and other domesticated grains/cereals, 1-8 leaves (depending on size) is adequate.
For impatiens, place 10-30 diseased leaves on dry paper towels.
For Rudbeckia and Sunflower samples, 4-6 leaves is adequate. Branches, without soil/roots, can also be sent.
Cover with a second paper towel, then seal inside a Ziploc-style plastic bag.
Step 2: Print out forms
The sample submission form
The domestic APHIS permit
For international samples (outside the continental U.S.), write so we can send you the red APHIS mailing label.
