A tightening of the leash on the use of a common pyrethroid insecticide is highlighted this month, with a new approval of the cypermethrin-containing product Permasect C.

The existing approval continues to be valid and on sale, which makes it all the more important that users are aware of the two approvals to ensure that they are using each product in accordance with the label.

Changes include an increased aquatic buffer zone and a non-target arthropod buffer zone adjacent to non-crop land extended to all crops, not just cereals. In effect, growers won’t be able to spray 5m from un-cropped land next to a field margin, unless it has a watercourse, in which case it is 18m.

There are also tweaks to maximum number of treatments and harvest intervals for some crops – these are likely to be common as insecticides in particular are reviewed.
