This is the first year I've used them
You make a good point, Blufloyd and it's why I've never used them before. We had a bad outbreak last year and I wanted to try to catch as many as possible. We also use biological and soap sprays since we won't use petrochemical pesticides.
Here's the scary part: the neighbor's soybean field is being stripped so he sprayed yesterday, as have most farmers in the area. They have never had to do that before. His field corn surrounds our property or it would be worse.
We can thank global warming - we didn't get a winter kill last year and everything is out of whack. - Roberta
