Dave Pehling, 425-338-2400, will take commercial calls and walk-ins. He is an expert diagnostician, who can often do plant disease, insect, weed and plant identification and save you the delay and fee associated with sending a specimen to the WSU Puyallup Lab. University regulations do not allow Master Gardeners to handle commercial questions, other than to take down information, so please identify yourself as a horticultural professional.
