In a crop field cull, how do the knives of judgment distinguish saint from sinner? A new approach uses a fluorescent systemic marker that is applied onto seeds through a seed treatment. When the plant is stimulated with a special color of light, it emits a fluorescent color.
ARS research agronomist Frank Forcella believed sandblasting organic grit would be an effective weed killer. His determination to break from convention has resulted in a four-row grit blaster capable of obliterating weeds.
Jason Norsworthy is attacking the soil seed bank with a no-prisoner policy: capture, burn and kill. Norsworthy is testing a new weapon in the resistant weed wars aimed directly at the seed bank reserve – narrow-windrow burning.
Fluorescent marker technology could be a major weapon in weed battle
When buying and transporting used equipment, pigweed has been known to tag along for the ride.
The weed battle merges herbicides with cultural practices
Depending on what stage of the crop’s lifecycle the weeds emerge, growers could see weaker, suppressed weeds that don’t steal as much yield, or strong, huge weeds that wreak havoc.
