| Unfortunately there is nothing you can do to kill those buggers once their in the stem. I have battled these buggers for years. Roughly 7 or 8 years ago I was told by a University of Nebraska agronomist that I had a severe infestation. The worst he'd seen that year. These are some of the things that I and a neighbor started doing.
1: Spray grassways and endrows with Bifenthren. The hatch starts early june and can go for over a month. They hatch in the soybean field from the previous year. Winds carry the little flying buggers to the closest current bean field. Its a a real PITA but I sprayed endrows every 2 weeks for a month. Sometimes with our big sprayer. Other times with our side by side that sprays a 30 foot swath. I also would spray the endrows that had gall midge the previous year. That is where their coming from. I'd spray the roadside ditches between my beanfield and cornfields.
2: Where I have had them bad is next to a big creek. Neighbor on the other side was always corn when I was beans. So basically they were flying back and forth every year. I went COC to match up with him.
So far I have not had any real bad years since I started doing this. Is it something I had done? Or is it environmental? I'm not sure. I too have heard that Thimet just on your endrows works. Generally they are just in the first 16 to 32 rows. Unfortunately my field had them through the whole field. We had 65 to 70 bushel beans that year. This farm didn't make 40. | |
