Make sure your garden amendments are free of persistent herbicides (Horticulture/Urban IPM)
Description: With the fabulous spring-like weather many of us are out in the garden getting ready for summer. If you are applying compost, manure, or straw I recommend reading the attached publication to help avoid using amendments that are contaminated with persistent herbicides. In 2016 the Schutter Diagnostic Lab received 17 vegetable samples with symptoms consistent with herbicide carryover from contaminated amendments.

Carpenterworms in Cottonwoods (Horticulture/Urban IPM)
Description: Not all wood-boring insects are created equal! Most often, we think that beetles are the culprits. But this is a caterpillar that came out of a removed cottonwood tree from a shelterbelt just recently (thanks to John for the sample!). It is a carpenterworm and will be a moth when it is an adult. See this attached sheet for more information.
