New and improved wild oat spray on the market
The main news at Syngenta’s technical briefing this week was the introduction of Axial Pro to the market for 2019.
The new formulation of pinoxaden has improved efficacy, something that is essential in order to slow down the resistance of wild oats and other problem weeds to the chemistry.
Resistance to chemistry
AgriLand recently published results from research carried out by Ronan Byrne at Teagasc Oak Park who found that 55% of 36 sites sampled in Co. Wexford were resistant to Axial (pinoxaden), Falcon (propaquizafop), Foxtrot (fenoxaprop) and Stratos Ultra (cycloxydim).
Correct rates essential
Using the correct rate is essential to prevent and slow down resistance. Robust rates will ensure good control and therefore reduce resistance build up.
The new product contains a built in wetter – taking away the need for the use of Adigor (an adjuvant) in most cases.
Where weeds are small a rate of 0.4L/ha can be used. However, Adigor at 0.5% of the spray volume should be added to the tank when using this low rate.
Ryegrass contol is successful on smaller weeds at 0.6L/ha. However, the full label rate of 0.82L/ha should be used on larger weeds – exceeding GS22.
Axial Pro also provides effective control on awned canary grass, loose silky bent grass, rough-stalked meadow-grass and onion couch grass.
It should be noted that where Axial Pro is being applied with broad-leaved herbicides the full label rate should be used – 0.82L/ha.
