Trialled in New Zealand, Ohio and New York with results in controlling Botrytis, Sclerotinia, leaf mould, and suggestions on other diseases like black mould, Phoma rot and anthracnose.
Trialled in New Zealand and Turkey. Results in Botrytis and Sclerotinia.
AMOUR-Zen® was trialled as a protective. There was no disease symptoms but weather conditions were suitable for Botrytis. Application was made on a plot in Turkey. 10 days after, Botrytis disease was observed along with Powdery Mildew. 2 applications were made a protective and a curative. 15 days after application, there was no new disease observation.
Trial was tested over a period of 30 days in Village Farms, Texas, USA. Tomatoes responded well on day 1 after application of BOTRY-Zen®.
BOTRY-Zen® showed to be effective in controlling leaf mould on tomatoes in a trial conducted in two tunnels at the New York State Agricultural Experience Station.
Trial involved using applications of BOTRY-Zen® and AMOUR-Zen® on tomatoes in Hawke’s Bay, New Zealand. Findings showed that high levels of Botrytis control provided by applying BOTRY-Zen® at bloom and suggests that this is the most effective time for Botrytis control. The incidence of black mould, Phoma rot and anthracnose was 2-3 times higher than Botrytis rot incidence in the unsprayed treatment. Despite greater fruit rot pressure, BOTRY-Zen® significantly reduced rots and remonstrated efficacy against the other tomato rots. This is the first report of which that indicates the active ingredient in BOTRY-Zen® also has efficacy against other tomato fruit rots in addition to Botrytis and Sclerotinia.
The control of Botrytis and Sclerotinia with BOTRY-Zen® was tested in the 2004-2005 season in Hawke’s Bay, New Zealand process tomatoes. Although the disease levels were relatively low, BOTRY-Zen® applications over flowering reduced Botrytis incidence compared with the unsprayed and fungicide treatments (Table 2). The crop loss caused by Sclerotinia was very low and there were no clear differences between the treatments for Sclerotinia control (as shown in Table 2).

BOTRY-Zen® has also been trialled by an organic glasshouse tomato grower with promising results; although deposits were left on fruit, which had to be washed off prior to sale.
