Now is the time for bark beetle control!

Bark beetles begin to infest your trees in April!  Pruned trees or those that have escaped bark beetle attack so far can be chemically treated to prevent infestation this spring and summer.  Remember, it’s important to remove, chip, burn, or tightly cover any infested wood or limbs, or bark beetles may emerge and attack additional trees. Depending on your location in the Gorge, there are about 6 weeks left before the California Five-Spined Ips bark beetle will begin to emerge and attack new ponderosa pine trees. They will also attack ornamental pines such as scotch and black pines.   Because this beetle has three generations per year (adults have peaks of emergence in April, July, and September), it can spread to many trees in one season.

Fall insects and disease control: prevention

Posted by on Oct 2, 2013 in Blog - tips and comments | 0 comments

Fall is an excellent time to treat trees with systemics for controlling several of our insect and disease problems: bark beetle,  pitch moth, black pine leaf scale, oak pit scale and other scale infestation, as well as sapwood stain fungi introduced by bark beetles, anthracnose branch die-back in oak, and  thousand canker disease in black walnut. These problems can be treated so long as conifers (evergreen trees) are active, through at least the end of November, and for hardwoods (deciduous trees) as long as leaves are on the tree and mainly still green. The systemic chemical is taken up in the sapwood from ground-based injection, and depending on the chemical, also spreads in the inner bark, the phloem. It is then ready to work  for the spring season when many insects and diseases attack trees. Please see other pages on the website for more information and photos: Insect and Disease...
