Join the North Texas Cactus and Succulent society on Tuesday, May 5th , 7:30 p.m. on ZOOM and take a walk on the wild side with Harald Grieb, a trained horticulturist/botanist and cactus enthusiast who will show us what common pathogens and pests look like both under the microscope and to the naked eye. You will come away with a heightened awareness of how to identify various entities that mean your cactus harm, gain a better understanding at what is happening at the microscopic level and acquire insight into common ways to dispatch these pests. This highly unusual and informative work represents over 20 years of keen observation by Harald, who is a USDA-APHIS-PPQ Area Disease Identifier/Botanist based in El Paso, Texas, where he diagnoses plant diseases and disorders, extracts and identifies nematodes, plant seeds and also CITES-regulated plants.
