Look to the sky—research finds resistant pigweed spread by waterfowl
10,000-farmer sample seeks best management plan answers to resistance
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.
