SOLA given for weed inhibitor

The HDC has secured a specific off-label approval (SOLA) for desiccant carfentrazone-ethyl, marketed as Shark, for spawn and weed suppression in cane fruit crops.

Shark is to replace sodium monochloroacetate (sold as Croptex Steel and Atlas Somon), which was revoked last season. The HDC worked to negotiate a critical use exemption, allowing continued use until a replacement was identified. During that time a screening trial of potential alternatives highlighted carfentrazone-ethyl as the best candidate for controlling spawn and weeds - both in outdoor raspberry crops and under protection.

The approval comes just in time for the new season.

Under the terms of the approval, Shark can be applied to protected and outdoor crops of raspberry, blackberry and rubus hybrids at a maximum individual dose of 0.8 litres/ha and a maximum total dose of 1.6 litres/ha. A minimum interval of seven days must lapse between applications and a 21-day interval between application and harvest.
