In New Zealand our products are registered for grapes, kiwifruit, blackcurrants and peonies and the diseases Botrytis Cinerea, Sclerotinia Sclerotiorum and Pseudomonas syringae pv. actinidiae (Psa-V). A lot of trial work is and has been carried out on other crops (fruit and vegetables). ACVM has confirmed that Botry-Zen is exempt under the ACVM legislation and as such it can be used off-label without any issues.
Our main product BOTRY-Zen® is registered in the United States under the trade name BotryStop®. For local state registration, it is registered in the states of California, Washington, Oregon and Florida under that same name. Successful trials and then registration has been carried out in Strawberries, Apricots, Cherries, Nectarines, Peaches, Plums, Plumcot, Prunes and Almonds, and against the diseases Botrytis Cinerea, Monilinia and Sclerotinia Sclerotiorum.
Many years of trials have shown the effective control of Botrytis with BOTRY-Zen® and ARMOUR-Zen®. BOTRY-Zen® works from flowering, colonising the nutrient rich flower caps and aborted berries. With the recent addition of MIDI-Zen® growers are able to add in to their programme a product that directly controls Botrytis and has the added advantage of controlling powdery mildew at the same time.
The target for disease control is petals that adhere to the fruit, aborted fruitlets and decaying leaf / vine material. Applications should be made at flowering for Sclerotinia and Botrytis control. BOTRY-Zen® currently has a Limited Claim for Psa – Not Fully Proven.
BOTRY-Zen® replaces the chemicals used for Botrytis in blackcurrants. This results in a full season residue-free Botryticide programme with no reduction in Botrytis control.
Trial was established to evaluate Botry-Zen® for the control of Botrytis fruit rots on strawberry. Conditions during the early part of the trial period were warm and sunny. Disease levels were initially low but two significant rain events provided wetness and humidity allowing for some disease development in the fruit, both at harvest and in storage.
