Time To Scout For Potato Leafhopper

It is time to have your sweep net out and be scouting for potato leafhopper (PLH) in your alfalfa field. The recent rains have brought PLH into our region from the south where they overwinter. So, get that sweep net out and start checking to see if they are in your alfalfa fields. The piercing and sucking feeding of PLH means that their feeding isn’t obvious and damage (stunted plants and yellowing leaves) won’t show up until a few weeks after feeding. Consequently, scouting with a sweep net is the best method to determine when you need to spray.

IPM of PLH requires knowing the value of the silage or hay. Below is the updated threshold chart with higher values than in older charts.

Video: Heat Stress in Pigs: What to Prepare for Before Next Summer - Dr. Joshua Selsby

In this episode of The Swine it Podcast Show Canada, Dr. Joshua Selsby from Iowa State University explains how heat stress affects swine biology and why now is the ideal time to prepare for next summer’s challenges. He breaks down its effects on muscle function, immune responses, and long-term metabolic outcomes. Learn how early planning can protect herd performance when temperatures rise again. Listen now on all major platforms! "Heat stress leads to a cascade of biological damage, beginning with metabolic disruption and expanding across multiple organ systems." Meet the guest: Dr. Joshua Selsby is a Professor in the Department of Animal Science at Iowa State University. With over 15 years of research on skeletal muscle physiology and heat stress, he focuses on understanding how thermal stress disrupts swine metabolism, immune function, and muscle integrity.
