A plant growth regulator for use in winter oilseed rape.

DIRECTIONS FOR USE
IMPORTANT: This information is approved as part of the Product Label. All instructions within this section must be read carefully in order to obtain safe and successful use of this product.
CARYX is a plant growth regulator for the reduction of crop height and lodging risk in all varieties of winter oilseed rape.
By reducing the incidence and/or severity of lodging CARYX may help to protect from yield losses associated with lodged oilseed rape crops
 
Restrictions/Warnings
Avoid boom overlaps and ensure that the boom height is correctly adjusted.
Extreme care should be taken to avoid damage by drift onto plants outside the target area.
Ensure the sprayer is free from previous chemical residues that may harm the crop. Use of a detergent cleaner is advised before and after use.
Use of a growth regulation product can offer good protection from the incidence or severity of lodging but there can be no guarantee that lodging will not occur, especially in high lodging pressure situations.
 
Crops
CARYX can be used on all varieties of winter oilseed rape.
 
Spring application of CARYX
CARYX applied at 1.4 l/ha in the spring will shorten the crop and manipulate canopy structure, reducing the risk of the crop lodging.
Application timing
Apply CARYX in the spring between crop growth stage 31-59 of the crop (beginning of stem extension to yellow bud) once the crop is actively growing
. Applications made before the crop has shown signs of active growth will be less effective.
Reduction of lodging risk
CARYX applied in the spring will reduce the risk of lodging later in the season.
Maintaining the rate of CARYX will provide a more consistent reduction of lodging risk by lowering the incidence or severity of lodging.
Autumn followed by spring sequence of CARYX
Caryx may be used in an autumn / spring sequence to regulate crop growth going into winter; and shorten the crop and manipulate canopy structure in the spring, reducing the risk of lodging later in the season. Use of this sequence is only recommended on forward crops.
Application timing
Apply Caryx as 1.4 l/ha in the autumn between growth stages 14-19 of the crop (4-9 leaves) and follow up with a second application of 1.4 l/ha in the spring between growth stages 31-59 of the crop (beginning of stem extension to yellow bud).
Autumn applications should only be made to forward crops. A forward crop can be defined as a crop that has the potential to grow to more than 25 cm tall by the end of autumn growing season. Shorter crops will benefit less from an autumn application and are best managed by solo spring applications.
The potential for a crop to reach this height is dependent on a number of factors for example; weather conditions post application, fertiliser regime, plant population, the nutrient and water content of the soil and variety.
Both autumn and spring applications should only be made when crops are actively growing and conditions remain conducive to continued growth.
Applications made after crop growth has started to slow in the autumn or before the crop has shown signs of active growth in the spring will be less effective.
 
Mixing
Never prepare more spray solution than is required.
SHAKE WELL BEFORE USE. Fill the spray tank three quarters full with water and start the agitation. To ensure thorough mixing of the product, invert the container several times before opening. Add the required quantity of CARYX to the spray tank while re-circulating. Fill the tank with the remaining required amount of water and continue agitation until spraying is completed.
On emptying the product container, rinse container thoroughly using an integrated pressure rinsing device or by manually rinsing three times. Add washings to sprayer at time of filling and dispose of container safely.
Application
Apply CARYX in 200-400 l/ha water as a MEDIUM spray, as defined by BCPC.
Qualified Approval:
CARYX may be applied at up to 1.4 l/ha in 150 litres water per hectare although efficacy at this reduced volume has not been evaluated. Therefore application at 150 litres water per hectare is at user’s risk with regard to biological efficacy.
To ensure optimum spray coverage and minimize spray drift, adjust the spray boom to the appropriate height above the crop according to guidance provided by the sprayer and/or nozzle manufacture.
Sprayer cleaning
Wash sprayer thoroughly immediately after use, using clean water and following the guidance provided by the equipment manufacturer.
Following crops
Following crops after normally harvested winter oilseed rape
After treating a crop of oilseed rape with CARYX, the crops listed below may be sown as a following crop:- Beans ,Clover, Oilseed rape ,Ryegrass, Cabbage, Lettuce, Onions, Sugar beet, Carrots, Linseed, Peas, Sunflower, Cereals, Maize, Potatoes .
The effects of Caryx on other crops has not been assessed.
Re-drilling due to crop failure in the autumn
In the event of crop failure, the following crops may be sown after cultivating to a depth of at least 15 cm:
Re-drilling the same autumn:
Winter wheat (excluding durum wheat), winter barley, winter oats, winter field beans, winter oilseed rape.
Re-drilling the following spring: Spring cereals (including oats), maize, peas, beans, spring oilseed rape, linseed, sugar beet, sunflower, onions.
Crops not suitable for re-drilling after crop failure in the autumn
Due to a risk of crop damage it is recommended that grass crops, for example ryegrass, are not re-drilled in the same autumn or subsequent spring following a crop failure in the autumn.
