Watch Your Speed pt.1

As I am waiting for a chocolate cake to finish baking, I am aggravated that this Kansas weather has given us another taste of winter. Looking out the kitchen window, I can see the limbs of the trees bending like they are doing some sort of yoga pose. The Dead End sign at our driveway is wiggling left to right, right to left, close to 180 degree turn.


In pesticide application, weather and wind are a huge factor pertaining to when, where, and how products can be applied. Today is NOT the right day to attempt any chemical applications. Drift would be a huge factor today. The applicator would positively, (negatively) get chemicals on him/her, regardless of the label requirements for PPE.

Non-target insects, like bees, would be affected. Residue-coated buildings, cars, homes, kids toys, and other items could cause allergic reactions when touched later. Field crops, flowers, and vegetable gardens most likely would suffer. Pets are sensitive to pesticides. That fancy Koi pond in the backyard would be nonexistent.


Tempo S.C. Ultra is a product most of us are familiar with, so I will reference this. Farmers have used some formulation of Tempo for years, even decades. The label says – Use in calm weather where no precipitation will occur for 24 hours. Apply away from (listed aquatic) areas. Don’t allow drift. It even restricts application to certain types of grassland.


While there isn’t specific wind speed or temperature recommendations on this label, good judgment is a must with any application. Take care to be weather aware when planning a pesticide application.

Because I know you are still thinking about the chocolate cake, reread this post.

My career in pest management began while working in a flour mill as the “in-house” technician in 2008. I am certified in multiple states. I began working full time as a fumigation-pest control tech in 2010. I achieved my Associate Certified Entomologist (ACE) in 2018. I have a Master Tech certification from Kansas State University/Kansas Pest Control Association. I hold a Bat Management certification from NWCOA. Every day, I realize how much I DON’T KNOW. My goal for this blog is to share my every day experiences from the field and to make us all think outside the box for solutions to make pest control make sense.
