Long before biological control became mainstream in agriculture, Dr Michael “Mike” Morris was quietly proving that nature itself could be one of farming’s most powerful allies.
From the late 1970s onward, Mike emerged as one of South Africa’s pioneering plant pathologists. He was among the very first scientists in the country to seriously explore the use of plant pathogens, particularly fungi, to control invasive weeds and crop pests. At a time when chemical solutions dominated agricultural thinking, Mike was already asking a different question: what if biology could do the work instead?
Over the next 19 years, Mike successfully introduced several plant pathogens into South Africa for weed control, including the now-famous gall rust fungus used against Port Jackson willow (Acacia saligna). His work was so influential that the fungus itself was later renamed Uromycladium morrisii in his honour, a rare recognition that reflects the depth of his contribution.
But Mike’s legacy is not only scientific – it is deeply human.
When he saw the potential to move biological control out of research institutions and into real-world agriculture, there was no funding, no formal facilities, and no established industry to support him. So he built one himself – starting at home.
Part of the Morris family home was converted into a laboratory. Two of the children were moved out of their bedroom to make space for fungal cultures. The laundry became a growing room. A discarded electric geyser was repurposed into a steam generator. A local farmer-engineer helped build the first small growth chambers. It was improvised, inventive, and driven entirely by belief in the work.
Behind the scenes, Mike’s wife Mavis, held the family together, helping on the farm, rearing calves for a neighbouring dairy, and working mornings at a preschool in Mooi River to support the household during these demanding years. Their shared sacrifices made it possible for Mike to continue refining production methods, scaling up operations, and developing formulations that could finally bring biological control to farmers in a usable, reliable form.
In 1999, Mike, together with Prof Mark Laing, founded Plant Health Products CC (now operating as Andermatt PHP), to commercialise biological control agents such as Trichoderma. Mike’s role was clear: translate science into practice. He developed mass-production techniques and practical formulations, work that helped transform biocontrol from an experimental idea into scalable agricultural solutions. In 2000, PHP received funding from the Innovation Fund of South Africa’s Department of Science and Technology, which supported the young company to set up a pilot production plant.
Today Andermatt PHP proudly offers seven products to growers in over 20 countries, with effective biological solutions for disease, pest, and soil health management across diverse crops and production systems.
Long before sustainability and biological solutions became mainstream talking points, Mike Morris was already living that future – guided by science, personal resilience, and the quiet, unwavering support of his family.
His story is not just one of innovation, but of belief in God’s guidance: belief in biology, belief in better farming, and belief that meaningful change often starts at home.
