Leaf growers to benefit from new off label pesticide approvals

New pesticide approvals from the Horticultural Development Council are set to bolster defences for salad and Chinese leaf growers.

The new set of Specific Off Label Approvals (SOLAs) will be a welcome development at a time when the industry faces potentially substantial pesticide losses  in the current EU pesticide review.

The approvals are for:

Plenum WG (active ingredient pymetrozine) has been granted approval of use for the control of peach aphid (Myzus persicae) on outdoor kale, and collard. It has also been re-issued for use on Chinese cabbage, choi sum and pak choi following an earlier revocation. The product can be applied anytime aphids are present or when risk is predicted. The council advises a maximum of two applications made in sequence to prevent resistance.

Folicur (active ingredient tebucinazole) has been reinstated for use on outdoor grown pak choi and choi sum for the control of ringspot (Mycosphaerella brassicicola).

Switch (active ingredients cyprodinil and fluidioxinil) has been given approval as a fungicide for the control of botrytis ssp on a range of outdoor and protected crops including cress, frisee, lambs lettuce, radicchio, rocket and scarole. This is a re-issue after the revocation of use on parsley, chervil, herbs, chives and beet leaves. Growers are advised to test a small area of crop prior to full use. Gazelle and Gazelle SG (active ingredient acetamiprid) have also been given approval for use on the same crops as well as parsley and baby leaf brassicas.

At the same time a revocation for the off label use of Gamit 36 CS (active ingredient clomazone) on outdoor herbs has also been issued following a new European Community minimum residue levels regime coming into force on 1 September.

Current MRLs for the product are not supported by the new regime.
