But Idaho beet growers may be facing a new challenge. Gordon Vail, Technical Product specialist in herbicides tells us about a list of the most challenging weeds.
So Roundup resistant waterhemp which has been newly discovered in Idaho can grow to 8 feet tall and resembles Palmer amaranth, a close relative that farmers fear may soon arrive in Idaho and bring a suite of resistance challenges.
Waterhemp can be differentiated from Palmer amaranth by its shorter petioles, which attach leaves to the stalk. A single waterhemp plant can produce upwards of 250,000 seeds.
Adjesiwor suspects the waterhemp was introduced in the 100-acre field by cattle that had been fed rations contaminated with waterhemp seeds.
