Aggressive weed brings trouble for Texas cotton growers

Posted: Updated:

LUBBOCK - A fast-spreading weed is causing problems in Texas cotton fields and could cost growers much of their harvest if left unchecked.

Pigweed is spreading aggressively in the High Plains this year after becoming resistant to the herbicide that once easily eradicated it. Above-average rainfall is 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.
