Plant sampling for disease diagnostics.
If possible, send entire plants including roots and some soil. Roots and soil should be in a plastic bag tied off at the soil line to prevent soil from touching foliage. Because plant material degrades fairly quickly; they should be dropped off in person or sent with overnight or priority shipping for proper diagnostics.
Leave the plugs in the tray for shipping purposes. A section of the tray can be cut and shipped. Submit a minimum of 12 plugs. Wrap the plug sheet in newspaper or add packing material that will prevent plugs from being dislodged from the tray. Because plant material degrades fairly quickly; they should be dropped off in person or sent with overnight or priority shipping for proper diagnostics.
Leaf Spots Samples
Select affected foliage, but if possible leave it attached to the branch. Send several affected samples representing the early and moderate stages of symptom progression. Although the sample may seem flat enough to package and ship in an envelope, please package and ship in a box. This protects the sample during the shipping process.
Vascular Wilt diseases (E.g.; Verticillium Wilt, Fusarium Wilt)
Select plants that are partially wilted, with symptomatic leaves progressing from the tip of branches inward to the stem. Be sure that branches are not totally wilted, dry, or dead. Select samples from up to three symptomatic plants per 500m2. Branch samples should be at least 1 inch in diameter, cut into 6- to 8- inch lengths, and placed in large re-sealable plastic bags. Keep samples cool during sampling, shipping and storage, but do not freeze.
These samples include plants, fruit, or both. If fruit rot is a concern select fruit that is in the initial stages of symptom development. Be sure to package in leak proof containers (sealable plastic bags).
Include a square of turf from the margin of the diseased area so that both healthy and diseased turf is included. Minimally, the turf square should be 6 inches x 6 inches. An intact layer of soil should remain on the root system. Wrap samples in newspaper and pack in a box for shipment. Do not add moisture to the turf prior to shipment.
NOTE:If possible;provide a detailed description of cultural practices (irrigation, fertilization, pesticide application, etc.) and images of the symptoms in the greenhouse/field/ lawn with the sample.
