DIRECTIONS FOR USE
Restrictions/Warnings
Only use on crops at risk of lodging DO NOT apply MEDAX MAX to any crop suffering physical stress caused by waterlogging, drought or other conditions. Crops with a substantial moisture deficit should not be treated. Care should be taken to avoid overlap of spray swaths. Avoid spray drift on to neighbouring crops. MEDAX MAX may be applied to crops undersown with grasses and clovers.
Height reduction and lodging control
MEDAX MAX is a plant growth regulator for the reduction of crop height which can lead to the control of lodging in winter and spring wheat, winter and spring barley, winter and spring oats, winter and spring durum wheat, rye and triticale.

Rate of Application
Apply in 200 litres of water per hectare. Qualified recommendation MEDAX MAX may be applied up to 1.0 kg per hectare in 100 litres water per hectare although efficacy at this reduced water volume has not been evaluated.
Following crops
Any crop can follow normally harvested or a failed cereal crop treated with MEDAX MAX and ploughing is not essential before sowing the next crop.
Mixing and application
Mixing
Never prepare more spray solution than is required. Half fill the tank with clean water and start the agitation. Slowly add the required quantity of MEDAX MAX to the spray tank while re-circulating. Add the remainder of the water and continue agitation until spraying is complete. Tightly close the lid on any unused MEDAX MAX before storage. On emptying the container, rinse container thoroughly by using an integrated pressure rinsing device or by manually rinsing three times. Add washings to tank at time of filling and dispose of container safely.
Application
Apply as a MEDIUM spray, as defined by BCPC.
Sprayer cleaning
Wash sprayer thoroughly immediately after use, using clean water and following best practice advice and the guidance provided by the equipment manufacturer.
