Invasive of the Week - Japanese Knotweed Popping Up stone.91@osu.edu Thu, 04/16/2020 - 06:31
Often we take notice of invasive plants when they are most obvious - they are in bloom, have put on their yearly growth and are standing tall or maybe wide in some cases, and really can't be missed. But today, I wanted to share an early view of an invasive perennial, Japanese knotweed (Fallopia japonica). That review includes last year's left-overs, hollow stems standling leafless.

Personal Protective Equipment Shortages for Pesticide Applicators

This spring pesticide applicators are likely to encounter a new challenge getting the personal protective equipment (PPE) required to make their pesticide applications. The emergency needs that first responders and medical care providers have for PPE in the COVID-19 battle have led to shortages of all types of PPE, even for types not typically worn by medical personnel.
