The Weed Science Society of America (WSSA) recently released a fact sheet that covers the main topic of weed seed longevity. Other topics addressed include how seeds travel, germination and ways to eliminate weeds.
Weeds are an ancient problem for small and large agriculturists. The new WSSA fact sheet helps to eradicate some weed issues. A few facts included in the resource are:
- The broadleaf weed Palmer amaranth has been found to produce as many as a million seeds per plant.
- Seeds of most annual weedy grasses die after two to three years.
- Tillage is an especially common trigger of weed seed germination.
- Earthworms are known to collect weed seeds and move them into their burrows.
- Specially equipped airplanes have discovered horseweed seeds in the earth’s planetary boundary.
