Refinzar® for OSR Autumn disease control

Oilseed-Rape disease control in the autumn

Phoma and light leaf spot are the major yield-robbing diseases of oilseed rape in the autumn.

Phoma and light leaf-spot symptoms on OSR

Phoma infection typically arrives in the autumn, infects leaves and ultimately causes cankers of the stem. Yield losses as a result can be up to 0.7T/ha. Light leaf spot typically starts it’s infection in the autumn and then continually re-infects new growth on the plant ultimately leading to yield losses of up to 1.0T/ha. Because of this continual re-infection from light leaf spot, seasonal control needs to be considered as a programmed approach and several applications will need to be targeted at the disease in high risk situations. Refinzar® is an ideal start to this programme offering excellent protection from both Phoma and light leaf spot. 

The active ingredients in Refinzar® are also found in Frelizon®, Cypher® and Sebrant®.
