To test the effectiveness of plant growth regulators on reducing plant height in irrigated barley
Response in barley seems to be variety dependent.
Early plant height reduction was noted in all varieties treated with Moddus Evo but had no effect on lodging.
Commander barley saw a yield increase with the use of Moddus Evo, but LatTrobe did not respond.
Off label high rates of triazole fungicides have to produced any PGR effects to date.
