It was roundup. I'm sure of it. I know my neighbors pretty well. Plus he told me he was gong to use it the day before. I asked him to do it real early in the morning when the wind wasn't blowing too. I also gave him some other pointers about spraying safely around here, like which nozzles to use and how much to mix and all. Most of us here use pretty fast ground speeds with big nozzles that make droplets instead of a mist. That's because it's always so windy here. Roundup will kill everything living on my farm. I've read the bottles before. Pecan trees, peach trees, cherry trees, Bermuda and alfalfa are all susceptible to it.
Some of the Alfalfa has started showing signs of being hit by it. The top leaves on the plants have started turning colors. It's not looking too bad though. My fence lines from all the way over on his side to the one side of my alfalfa field got hit hard though. Those weeds are really laying over. Maybe they blocked some of the mist I'm hoping.
We haven't turned off the sprinklers on the alfalfa though since it happened. Hopefully most of it has been rinsed off in time. I'm sure the 6 inches of water I've put down so far didn't hurt at all either. I usually only do 3 inches a week.
If they made roundup ready pecan trees, I'd be planting a new orchard tomorrow. The RR Alfalfa is still held up in court battles and not on the market yet. I have one neighbor here that was lucky enough to get a few bags of it durring the very short time it was available about two years ago but noone else I know got any. The courts shut down sales of it real fast.
