EU review will hit herbicide use on pulses hardest of all

By Andrew Swallow

HERBICIDE use on pulses is set to be hit harder than most crops by the EU review of active ingredients, pulse research centre PGRO warned at its open day on Tuesday.

Terbutryn is not being supported in the review, so both Opogard (terbutryn + terbuthylazine) and Reflex T (terbutryn + fomesafen) could go after 2003, says weed specialist Jim Scrimshaw.

Fomesafen alone is not cleared for use on peas and beans either, so pre-emergence choice could be severely limited.

The future of Fortrol (cyanazine) is also uncertain, having been sold off by BASF. "If it is not supported that could go too. That would be a real problem on vining peas. It would leave us with virtually no pre-emergence or post-emergence combinations. In combining peas at least we have got Impulse."

But combining peas and beans are set to gain a new pre-emergence herbicide, subject to PSD approval, next year. Clomazone from FMC looks very useful as a cleavers killer and could allow growers to sow pulses where cleavers have prevented them from doing so in the past, suggests Mr Scrimshaw.

Check in plant tips for the large green, red-eyed, pea aphid, said the PGROs Anthony Biddle at the pulse research centres open day, which attracted a record attendance.

Dressing advance

A multi-action pea seed dressing, launched at the PGRO open day, promises to give growers more reliable plant emergence, says supplier Syngenta. Wakil XL, which will be available next spring, uses three active ingredients to stave off disease during germination. Metalaxyl-M provides systemic activity against downy mildew and damping off, penetrative fludioxonil protects against ascochyta, while cymoxanil gives translaminar mildew control, says product manager Bruce McKenzie.
