NEW OWNERS!

In April 2022, CERTIS BELCHIM NV, a multi-national agrochemical company based in Belgium acquired Henry Manufacturing’s portfolio of soft chemistry products – Protectorhml, HML32, HML Potum and HML Silco, along with a new product NSA.

In Australia and New Zealand, GROCHEM NZ are the designated distributors for the products (nz.grochem.com).

Research and development of HML products continues in New Zealand as well as elsewhere globally.

This website is maintained in the meantime to allow growers to obtain up to date research including research and information about the latest potassium soap fungicide NSA (obtainable under the ‘Our Products’ tab).

HML32 and Protector hml - Armour plate for grapes

Effective, non-residual solutions for viticultural disease control.

We provide growers with effective alternatives to conventional chemistry and low-toxicity options for specific diseases such as Powdery Mildew, Botrytis and Downy Mildew.

At Henry Manufacturing Ltd, everything we do is based on good science. We are led by data and results that have been proven in the field. Each year, we invest heavily in field trialling (both handspraying and machine spraying). Results of independent trials are published here. We have strong relationships with like-minded growers, scientists and industry consultants. Wherever possible, our formulations will comply with international standards for organic food production.
