About us

Established in 2003 by Murray and Elisabeth Mackay, Zantra is a farmer-owned and farmer-focused agrochemical supply business.

In recent years the company has secured, planned, measured growth, employing an increasing number of agronomists and is now one of the UK’s largest independently-owned agricultural merchants.

With headquarters at Garden Farm, Great Staughton, in Cambridgeshire, the company operates a nationwide network of BASIS approved depots.

Crop production

We supply an extensive range of crop production products including fungicides, herbicides, insecticides, plant growth regulators, molluscicides, nematicides, adjuvants, micronutrients, fertiliser and seed from a wide range of manufacturers.

The products we select allow us to provide you with the right, balanced, crop production programme from a wide portfolio.

Our service

We recognise that effective farming requires the right product applied to the crop at precisely the right time to maintain, protect and drive forward yield and productivity.

As a result, we provide a personal, professional and reliable advice and supply service that delivers the products you need, when you need them.


Our agronomy team provide the highest level of technical expertise backed up by our own independent regional crop trials.


Our farm supply and advice service is supported by our own independent trials at key locations in the main arable regions.

This work aims to address key issues such as weed, disease and pest resistance. It also helps to generate technical data to back our agronomist’s understanding of product performance as they strive to bring you the maximum return on your crop production investment.
