Steve’s question about Heat or UV light.
Hey, frank, This is Steve Jackson regular listing of the show first off. Let me come meet you when you’re interviewing skills interviewing is much harder than most people realize and especially when the record button is on and you did a great job with the Ian McGuire So kudos the both of you. He was he was wonderfully transparent and insightful so great job know if my question this summer up here in South Georgia. I use the new product on the market they did a really good job for bed bugs and the label says that steam will not kill the residual of the product so because of that means summertime I figured that I didn’t what a life on my exterior treatment if I use this particular product, but that clearly wasn’t the case so my question is is heat killing the residual of the product or is it the sun’s UV rays. Thanks for your help!
Thanks Steve for the kind words and your question this is a very thoughtful question that some in GHP do not ask and very few talk about I will attempt to answer it as best as I can.
The effect of UV light on pesticide
I have included several studies on the fate of pesticides, Photocatalysis, photodegradation, Photoionization, Photolysisand and Photosensitization.
Effect of light on the degradation of two neonicotinoids vs acetamiprid and thiacloprid in soil.
In the California Study “ENVIRONMENTAL FATE OF BIFENTHRIN”
“The photodegradation half-life on soil exposed to natural sunlight was 106 days for C-14 phenyl labeled bifenthrin and 147 days for C-14 cyclopropyl labeled bifenthrin (FMC 50429-025, 1983).”
Photodegradation of pesticides on plant and soil surfaces.
Rapid degradation of termiticides under field conditions.
