Fall Weed Control
I'm Lacy Gray with Washington Ag Today.
According to Kevin Hupp, Coordinator with Lincoln County Noxious Weed Control Board, fall is a great time to treat problem weeds.
HUPP: As far as weeds we're looking at all perennial plants - so your Canada thistles, Dalmatian Toadflax, then we're looking at Common Tansy. Those are the main hitters. Rush Skeletonweed is another range and pasture nightmare, and this is another great time to catch it.
Tenacious annual plants can still be targeted in the fall.
HUPP: Sometimes we have some annual plants that get a shot of rain in October, and this time of year - that's another great time when you actually see the visible annual plants. We really think of October as this is our next opportunity to get it.
For many growers fall is their one time for controlling weeds.
HUPP: You're trying to help yourself the following spring. So if they can use chemistries that have residual - that basically binds to the upper 64th inch of the soil and kind of stays around for any germination that wants to happen throughout the time. Maybe if they get a good shot of rain in November, and you've laid down a barrier of some degree in October, that's helping you in spring so these things aren't five foot by the time your schedule finally gets to it in let's say May.
