Medax Max

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, durum wheat, winter and spring barley, winter and spring oats, winter and spring durum wheat, winter and spring rye and winter and spring triticale.

Why Medax Max?

Temperature

Medax® Max has safe and reliable activity at temperatures down to 5°C, especially important for the first out-of-winter application. It does not need intense UV radiation to activate the ingredients. Medax® Max is rainfast one hour after application, giving you maximum flexibility against the weather.

The height and straw length of cereal plants is regulated by the balance of different plant hormones. If this balance is changed, the basic design of the plant is modified.​ By inhibiting gibberellin production, Medax Max reduces the plant height, which in turn reduces lodging risk.

Medax Max provides wider root spread of cereal crops for better anchorage. This enhances water and nutrient supply to the rest of the plant for stronger, healthier crops, even in drought conditions.

Medax Max produces thicker stem walls compared to competitor products, especially in earlier applications. Thicker walls reduce the risk of lodging – a particular problem for high yielding crops.

Unlike other PGRs, Medax® Max has a wide application window from growth stage 29 (end of tillering) to growth stage 49 (first awns visible). Medax® Max can be used at both early and later timings as a ‘one shot’ application or split dose so only one product is needed.

Medax Max is designed for use in all cereal crops. So whichever cereal crop you want to grow, Medax Max is the right choice. Not sure what the right rate is for your crop? Have a look at our rate reminder to find out.
