A growth regulator to improve the resistance of barley, ryecorn and triticale to lodging
Terpal® is a plant growth regulator, which shortens and stiffens straw of barley, ryecorn and triticale.
Advantages of treatment:
- Improves the resistance of vigorous crops to lodging
- Reduces yield losses associated with lodging, straw and neck break
- Harvest is made easier
- Fertiliser inputs can be aimed at optimum yields, rather than be limited to avoid lodging
- Tall growing, high yielding cultivars may be grown in high fertility areas where lodging would normally preclude their use
Terpal® is mainly taken up through the green parts of plants. Terpal should only be applied to vigorously growing crops which have an adequate supply of nutrients and moisture, and are free from any stress prior to and following treatment. Optimum results are obtained when Terpal is applied during the recommended stages of crop development. See Terpal label for recommended application stages.
The main effect is to shorten and thicken the stem between internodes on the parts undergoing stem elongation at, or following, treatment. Early treatments provide the greatest protection against basal lodging and later treatments are more effective at reducing straw and neck break.
Terpal is suited for application by ground or aerial spraying.
