Herbicide

Korvetto^® is a selective post-emergence spring applied herbicide for use on winter oilseed rape.

Best Use Advice

Applications can only be made from the 1st March in the year of harvest.
Treatments should be made prior to crop canopy closure and before flower buds are visible from above the crop canopy (BBCH 50).
Korvetto can be used from 8-25° C, in humid or dry conditions. Avoid applications in severe drought conditions or when frost is expected.
Take extreme care to avoid drift when applying near sensitive crops e.g. legumes, potatoes and carrots.
Chop and incorporate all treated plant remains in the early autumn (or as soon as possible after harvest) to release any residues into the soil, where they are more quickly broken down.
