Tips for Plant Disease Samples:

• Out-of-state samples must be packaged in two sealed plastic bags.
• Select plants or plant parts that are showing the problem but are not dead.
• Wrap samples in dry newspaper or paper towels. DO NOT ADD WATER.
• If sending whole plants, tie a plastic bag around the root/soil ball, or package the root ball separately from the top of the plant.
• Turf: Cut at least a 5 x 5 inch square of turf, including roots, and package in a tightly sealed plastic bag.
• More than one plant problem? Place each problem in its own bag to avoid contaminating the other samples. Label each bag for your reference. All bags can be shipped together in the same box or envelope.

Fill out plant diagnostic form for each sample and ship the form(s) and sample(s) in a padded envelope or sturdy box to the address above.

Tips for Nematode Samples:

• Use nematode bags from your county Extension office, or quart-size sealable plastic bags.
• Fill bags with approximately 1 pint of soil.
• Label each bag for your reference.
• Take soil samples to a depth of 6-8 inches. 
• Keep samples cool (do not freeze). Do not expose soil samples to high temperatures or direct sunlight. Do not let the samples dry out (make sure bags are sealed tightly). DO NOT ADD WATER.
