Plant growth regulators are nothing new for cotton farmers, but they are of recent interest to some wheat producers, who are questioning their efficiency and economics, said Dr. Jourdan Bell, Texas A&M AgriLife Extension Service agronomist in Amarillo.
Plant growth regulators have been used on wheat in Europe for some time, according to AgriLife Today.
“In wheat, as in cotton, there are many environmental and product interactions that come into play,” Bell said.
Plant growth regulators are natural and synthetic hormones, and it is critical that application timing takes place to enhance those interactions.
Bell said because of the limited information applicable to this region, producers should be cautious about the use of plant growth regulators.
