A new herbicide for broad spectrum weed control has been launched providing fruit growers with an alternative option for control this season.
Finalsan, a new biorational herbicide, is for the control of annual and perennial weeds, mosses and algae, for use around pome fruit, stone fruit, soft fruit, bush fruit and vineyards, with an Emergency Authorisation for Minor Use (EAMU) that also covers some vegetable crops.
Selchuk Kurtev, Certis’ IPM Manager, explains why the introduction of this product is so timely.
“Weed control is a major challenge for growers of horticultural crops, due to the limited number of products available, minimal investment in minor crops and the loss of approvals on some key conventional actives,” he says.
“Targeting young, actively growing weeds early in the season, can help to get on top of weed burdens and lessen pressure throughout the season.”
Finalsan contains 186g/L pelargonic acid and works by contact action that destroys the cuticle layer of the leaf and breaks down the cell walls. Subsequent exposure to the elements then results in desiccation.
Mr Kurtev explains that Finalsan was also trialled as part of AHDB’s SCEPTRE project which demonstrated the potential for runner control in strawberries. In addition, sucker control in wine grapes, general weed control in top fruit and inter-row weed control with the use of hooded robotic sprayers have been areas of investigation by the horticultural team at Certis
