Title: Drift Control 
Speaker: Bill Riden, Penn State Pesticide Education Specialist

Pesticide drift is the movement of pesticide dust or droplets through the air at the time of application or soon after, to any site other than the area intended. Drift can cause damage to property, non-target organisms and the environment . This talk will describe the causes of pesticide drift and steps that applicators can take to prevent drift. 

Title: Plant Galls of Herbaceous and Woody Ornamentals. 
Speaker: Thomas Butzler, Penn State Extension Educator

Plant galls are abnormal swelling or growth of plant tissue. They can be caused by mechanical injury or by several species of insects, mites, nematodes, fungi and bacteria. Many herbaceous and woody ornamental plants are susceptible to galls; gall damage can range from affected plants being unattractive (or unsalable) to causing pre-mature leaf drop or branch dieback. This presentation will discuss the many causes of plant galls and their impact on plant health. Cultural and chemical management strategies and proper pesticide application timing for gall management will also be discussed. Participants will gain hands-on experience with identifying plant galls commonly found on Pennsylvania ornamental plants.
