General Digital Photo Tips (Source: PPDL)
You can help us by following these guidelines:
- Please check your images before submitting them. If they look out of focus to you, they will not be helpful to us.
- When possible, please include a size reference such as a ruler or a coin. If taking a photo of a ruler, let us know units (ie. Size is about 2 mm).
- For plant identifications, please include whole plant image, as well as close-ups of plant parts (leaves, flower, fruit, etc.)
- As with actual samples, please include as much additional information as possible such as: planting date, age of plant, chemicals used, number of plants affected, where found, patterns, when symptoms first noticed, etc.

SUBMITTING PLANT SPECIMENS FOR DISEASE/INJURY DIAGNOSIS (SOURCE: PPDL)
For general decline/dying of plants, send whole plants, showing early symptoms, with roots and adjacent soil intact. Dig up plant carefully. Send several plants. Bundle plants together and wrap roots in a plastic bag. Wrap the entire bundle of plants in newspaper and place in a crush-proof container for shipment. Do not add water.
Collect branches 1/2 to 1 inch in diameter from branches which are actively wilting but not totally dead. Wrap in plastic to retain moisture. Collect a handful of feeder roots and place in a separate plastic bag.
When localized infections such as cankers, leaf spots, and rots are involved, send specimens representing early and moderate stages of disease. For cankers include healthy portions from above and below diseased area. Press leaves flat between heavy paper or cardboard. Wrap fleshy parts in dry paper.
Samples should be at least 4"x4" and include both the diseased and healthy portions of grass on the same sample piece. Place the sample on a disposable plate and wrap in newspaper for shipment.
SUBMITTING PLANT SPECIMENS FOR IDENTIFICATION
- Include a 6-10 inch sample of the terminal (tip) portion of the stem with side buds, leaves and flowers in identifiable condition.
- Place the sample flat between a layer or two of drynewspaper, paper toweling or similar absorbent material. Try to prevent excessive folding of the leaves and place flowers so that you are looking into the center of the flower.
- Pack the wrapped bundle in plastic, preferably with a piece of cardboard to keep the sample flat.
- Neverplace any fresh plant sample directly in plastic.
- Neveradd water to the sample.
- Shake excess water from aquatic weed samples and place in plastic bag.
- Wrap whole, uncut fruit specimens in paper, place in a strong box, and pack with additional paper to prevent crushing.
- Package in sturdy crush-proof container and pack with additional paper to prevent shifting.
SUBMITTING INSECT SPECIMENS
Care should be taken to package insects so that they arrive unbroken. Be sure to separate and label the insects if two or more are included in the same package and provide appropriate information on each.
TINY AND/OR SOFT-BODIED SPECIMENS
Aphids, mites, thrips, caterpillars, grubs, spiders, etc. should be submitted in a small leakproof bottle or vial of 70 percent alcohol. Rubbing (isopropyl) alcohol is suitable and readily available. Do not submit insects in water, formaldehyde or without alcohol as they will readily ferment and decompose.
*Grubs and caterpillars must be prepared before preservation to prevent discoloration. Drop them into gently boiling water for about 30 seconds (never microwave them!) before placing in vials of rubbing alcohol.
Flies, grasshoppers, cockroaches, wasps, butterflies and beetles can be submitted dry in a crush-proof container. Do not tape insects to paper or place them loose in envelopes.
