Quicker Plus is a plant growth regulator, which shortens and stiffens straw of barley, ryecorn and triticale.

Quicker Plus is mainly taken up through the green parts of plants. Quicker Plus should only be applied to

vigorously growing crops, which have an adequate supply of nutrient and moisture, and which are free

from any stress prior to and following treatment.

Optimum results are obtained when Quicker Plus is applied during the recommended stages of crop

development. The main effect is to shorten and thicken the stem between the internodes, on those parts

that are undergoing stem elongation at, or following, treatment. Early treatment therefore provides the

greatest protection against basal lodging, and later treatments are more effective at reducing straw and

neck break.

Advantages of treatment:

1) Quicker Plus improves the resistance of vigorous crops to lodging.

2) Yield losses associated with lodging, straw and neck break are reduced.

3) Harvest is made easier.

4) Fertiliser inputs can be aimed at optimum yields, rather than be limited, to avoid lodging.

5) Tall growing, high yielding cultivars may be grown in high fertility areas, where lodging would normally

preclude their use






- Do NOT apply Quicker Plus if rain or frost is expected, nor if the crop is wet.

- Avoid spray drift on to neighbouring crops.

- Do NOT apply Quicker Plus to crops on soils of low fertility, unless fertilizer and moisture are made

available to the crop.

- Do NOT use on crops on light soils that are likely to suffer from moisture stress.

- Do NOT apply Quicker Plus at temperatures above 21ºC.

- Do NOT apply to crops suffering damage or physical stress, e.g. frost, hail or herbicide damage, water

logging, drought or nutrient stress.
