Top Questions To Our Technical Helpline - March 2013

Ian Cockram

Since my last blog the continuing arctic weather conditions has meant that the technical helpline continues to be unseasonably quiet. However when spring does eventually arrive it is obvious that farmers will have much catching up to complete in a very short period of time.

Given these circumstances a typical question coming into the helpline is what interval needs to be observed after an application of Atlantis WG + biopower before applying a T0 fungicide. Whilst it is still far too cold to apply Atlantis WG we do advise that Atlantis WG + biopower is best applied alone to ensure maximum opportunity of success especially in adverse weather with large black-grass which might possibly also be herbicide resistant. Once the Atlantis has been applied the crop needs to recover from any possible de-waxing such that any further products should not be sprayed until a period of 5 to 7 days has elapsed.

The new EAMU for using Liberator on crops of spring barley has been attracting considerable interest. A commonly recurring question is :

Can the Liberator be applied post-emergence as well as pre-em ?.

The EAMU states that Liberator can be used up until before GS 24 of the spring barley.
