Cycocel 5C
A soluble concentrate containing 645 g/litre (57% w/w) chlormequat chloride.
A plant growth regulator for use in wheat, winter barley, winter and spring oats, rye, triticale and certain ornamentals.
DIRECTIONS FOR USE
New 5C Cycocel is a valuable input for high yield wheat and winter barley growing systems. The influence of New 5C Cycocel on growth will vary according to the crop and its stage of growth at the time of application. Application at early stem extension can lower crop height and the sturdier growth reduces the risk of early lodging which is known to adversely affect grain yield. This lodging control is most consistent in wheat and winter and spring oats. Applications earlier in the life of the crop can improve the root system development and can increase the number of tillers surviving to bear heads, which can result in increased yield.
On certain ornamentals (see below) the use of New 5C Cycocel can promote a more compact bushy habit.
Restrictions/Warnings
Avoid spray drift on to neighbouring crops.
New 5C Cycocel should be applied to crops during good growing conditions at the correct timing.
Do not apply New 5C Cycocel if rain or frost is expected, nor if the crop is wet.
Do not apply New 5C Cycocel to very late sown spring crops.
Do not apply New 5C Cycocel to crops on soils of low fertility unless these soils regularly receive adequate dressings of nitrogen fertilisers.
New 5C Cycocel may be applied to cereals undersown with grasses and/or clovers.
A split application is not recommended in spring sown spring wheat.
Caution is needed if using mixtures of liquid nitrogen fertilisers and New 5C Cycocel as scorching may result in certain circumstances.
Wash equipment thoroughly after use.
Winter wheat sown in the spring and autumn drilled spring wheats should be treated at the winter wheat rate of application.
Occasionally, when used in poinsettias, temporary yellow spotting may occur which can be minimised by the addition of an authorised non-ionic wetting agent at the rate of 2 ml per 5 litres of spray solution.
New 5C Cycocel reduces stem length in winter and spring oats under most circumstances but resistance to lodging will be greater in short-strawed varieties.
For full effect in winter and spring oats, an authorised non-ionic wetting agent at 25 ml per 100 litres must be added to the spray mixture, except when using mixes of New 5C Cycocel with Corbel.
The use of Terpal®1 sequentially in approved crops is recommended for reliable lodging control. See Terpal literature for full details.
Aerial application in cereals should not be made in tank mix with any other products.
Notes on application to ornamentals: Plants to be treated must be well established, growing vigorously, and with a healthy root system. Pot bound plants or plants under stress should not be treated. Do not treat in strong sunlight. Do not treat geraniums/pelargoniums when temperatures are likely to drop below 10°C. Compost should be moist prior to treatment. It is advised that the effect is checked on a small number of plants before treating the whole batch.
Do not use straw from New 5C Cycocel treated cereals as a horticultural growth medium or as a mulch.
Mixing and Spraying
Apply as a MEDIUM spray as defined by BCPC.
Half fill the spray tank with clean water and start the agitation. Pour in the required amount of New 5C Cycocel. Add the remainder of the water and continue agitation until spraying is completed.
When tank mixes are to be used, each product should be added separately to the spray tank, taking due note of any instructions given as to the order of mixing.
New 5C Cycocel may be applied from the air to wheat, winter barley, winter and spring oats, triticale and rye at the recommended rates in 25-60 litres of water per hectare, but results may not be as uniform as from ground applications.
When applied by air to winter and spring oats, New 5C Cycocel should be used in conjunction with an authorised non-ionic wetting agent at the recommended rate. Aerial application should not be made in tank mix with any other products.
