  • There are a number of NEW SOFT products being released

having obtaining NZ registration.

  • CORAGEN has been here since late last year and proved it’s

self successful in controlling DBM and WBF in brassicas.

  • SERENADE (Bacillus subtillus) is successfully being used to

help fight bacterial diseases such as Xanthomonas campestris and Psuedomonas syringae, also having label claims abroad for alternaria and downy mildew.

  • VITAMEX is used as a foliar fertiliser but being Phosphorus

acid based is having good effect controlling downy mildew and also bacterial diseases.
