The researchers also explored which harvested bird feed ingredients contributed most to weed seed contamination. They found that proso millet grain was closely linked to the presence of pigweed species weeds, while safflower and sunflower contributed most to the presence of kochia and common ragweed, respectively.
When researchers examined the contents of 98 commercially available bird feed mixes, they uncovered several significant findings:
“While it is difficult to estimate the precise role commercial bird feed plays, there is a distinct possibility it may be an overlooked pathway for spreading troublesome weed species into new regions,” says Eric Oseland of the University of Missouri.
Bird feed mixtures may be helping to spread troublesome weeds that threaten agricultural crops
Many millions of homeowners use feeders to attract birds. But a two-year study featured in the journal Invasive Plant Science and Management suggests there may be one unintended consequence to this popular hobby. Bird feed mixtures may be helping to spread troublesome weeds that threaten agricultural crops.
To mitigate the risks, researchers recommend careful weed management in crop fields designated for bird feed, as well as the use of sieving during packaging to reduce weed seed contamination. They also point to the proven effectiveness of regulatory measures adopted in Europe to limit weed seed content in bird feed.
Plant that bird seed, it contains millet (the small roundish white/tan seeds), sorghum (the red flattened sphere seeds) and oil sunflower seeds, (if there are any smooth very light colored seeds in it that would be canola seed) all are non-gmo products so no worries about that.
Furthermore, does thistle bird seed cause weeds? Niger seed used to be called thistle, but it is not the noxious thistle weed we see growing on roadsides. It typically will not germinate under your feeders since the USDA requires that all niger seed imported to this country be heat-treated to sterilize the seed.
Can bird seeds grow into plants?
There are several simple strategies to consider to avoid having your bird feeder become a weed seeder, the WSSA says: Use a tray attachment under your feeder to keep seeds off the ground. Select foods that won’t sprout, such as sunflower hearts, peanuts, peanut butter, raisins, mealworms, and plain suet cakes.
People also ask, what kind of plants grow from bird seed?
The type of bird seed that individuals are placing into their bird feeders controls the type of plants that will grow from bird seed. However, if you are feeding a mixed bird seed containing Millet and Milo, then something that looks like grass will grow.
