LUBBOCK (July 27, 2014) Pigweed is spreading aggressively this year in the High Plains after becoming resistant to the herbicide that once easily eradicated it and if left unchecked, it could cost Texas cotton growers much of their harvest.
Above-average rainfall has also helped the growth of pigweed, which can grow 10 feet tall and overtake crops.
Producers are checking their fields and seeking other herbicides to try to protect their harvests.
Eradication of pigweed gets more difficult if the plant goes to seed.
One female plant can have as many as 600,000 seeds that are carried by water but not wind.
Pigweed is a summer annual that's native to the Sonoran Desert and the Lower Rio Grande Valley and affects all row crops, including vegetables.
