The following are highlights and updates about samples and questions recently received in the Plant & Insect Diagnostic Clinic. Visit the PIDC’s Facebook page to ask questions and for updates and more pictures.
Evergreens continue to struggle! We have received samples, calls, and pictures of white pine, spruce, and arborvitae with brown needles. Most trees are still suffering from heat and drought in 2012.
We have also seen some veggies (tomato especially) with herbicide injury. Tomatoes are highly sensitive to some herbicides which are commonly used in lawns to control broadleaf weeds. More information about herbicide injury can be found in this article.
Other herbaceous plants are showing root rot problems. Remember to always check soil moisture before watering!
Spring is in the air and so are termite swarmers (picture below). Finding termite swarmer indoors means you should have your house inspected for termite activity. For more information please read our pamphlet on Selecting a Termite Control Service.
Termite swarmers. Note small black body, equal-length silver wings and shed wings, all typical of termite swarmers in the house.
