MU: Pigweed in 60% of seed mixes checked
Missouri researchers have found more than 60% of the pollinator seed mixes they’ve screened contain pigweed seed. Kevin Bradley, University of Missouri Extension weed scientist, tells Brownfield they’ve checked 30 to 40 bags so far. He tells Brownfield Ag News, “We’re trying to expand beyond Missouri and trying to get a bigger sample size. More mixes of various kinds.”
Bradley says the bags were purchased on the internet and from various seed dealers in Missouri. Often, he says, the mixes contain seeds from a variety of states – and those from Kansas and southern states are the most worrisome since those areas have high populations of Palmer Amaranth, a highly resistant pigweed. There are restrictions on weed management on C-R-P lands.
