FAQs - Sept/Oct 2016

The AUSTRAL PLUS label states that treated seed is to be drilled within 3 months of application because trials have shown that there would be a drop off in efficacy after that time. Grower can drill it, but will probably have no/very little pest/fungicide protection.

Trials have shown that AXIAL will give good control of barnyard grass at 0.45 l/ha from 2 lvs up to early tillering.

Syngenta will not support DEFY + Liberator post-em due to crop safety concerns. Syngenta will support DEFY 2.0 + Crystal 4.0 peri/post-em in winter barley with caveats that transient crop effect may occur post-em where crops are not sufficiently hardened off.

There is no concrete evidence for spraying HALLMARK ZEON at night. Trials are currently being carried out comparing spraying at night and during the day. The current recommendations are to spray as soon as threshold is reached or when the risk of CSFB is high, usually when it’s warm and dry. Remember some CSFB are resistant to pyrethroids, therefore control may not be complete and an insecticide with another mode of action is advised. If applying HALLMARK ZEON use at 50 mls/ha +/- a non-ionic adjuvant.

There is no label recommendation for this use, but trials have shown that PLENUM will give limited control of cabbage stem flea beetle (up to 30% control).
