GYRO is a plant growth regulator (PGR) that primarily acts by reducing crop height, which can lead to lodging control, resulting in the protection of crop yield and quality as the ears remain upright until harvesting.
GYRO can also be used to manipulate plant root growth and crop biomass. GYRO may be used on all varieties of winter and spring wheat, winter and spring barley, winter and spring oats, rye, triticale and durum wheat.
GYRO is an Emulsiﬁable Concentrate (EC) formulation.
GYRO inhibits gibberellin synthesis, slowing growth. GYRO is absorbed by the leaves and stems of cereals and ryegrass. It has no root or soil activity. GYRO is absorbed quickly into the plant tissue and rapidly translocated to the growing parts where the elongation of the stem internodes is inhibited thereby reducing the straw height. This reduction in straw height reduces the risk of lodging in cereals and ryegrass. GYRO treatment may lead to ears remaining erect through to harvest.
