Research being conducted on plant growth regulators (PGR) show the product can help a cereal crop but there are no guarantees.
There has been increased use of these products on the prairies, according to Dr. Breanne Tidemann, a research scientist with Agriculture and Agri-Food Canada based in Lacombe, Alta.
Tidemann said PGRs are chemicals that are applied to plants that change how they grow. In western Canadian agriculture, it is typically used to shorten the plants and then reduce their chance of lodging in field crops.
“Wheat and barley in particular are the two that we’re using them on, and the goal is to be able to up nitrogen rates and still get some increased yield, but not get the increased height with the plants falling every which way that we sometimes see when we do that,” Tidemann said.
