A WORD ABOUT US
Get to Know Us
If sustainable agriculture is defined as the ability to maintain productivity, one can find hints of attempts at "sustaining" agriculture since its inception some 6000 years ago. In fact one could contend, as some do, that since we have ably maintained productivity, agriculture as we know it is sustainable. The real question is whether current agricultural practices can be sustained much longer. Here at Exa Ag, we are committed to a single goal; we strive to make the world a better place. Explore our website to learn more about all that we’re doing to make a change.
Our Mission
Exa Ag's mission is to provide the grower with alternative solutions with sustainable fusion farming as the focus rather than conventional chemical control of pests and diseases. Combined experience of more than 60 years in Crop Protection puts Exa Ag in the position to provide superior Innovative Solutions.
Innovative Solutions
With our mission always in mind, we work tirelessly to improve crop health through addressing issues like nematodes, disease, weeds and the contamination of ground water. Our whole team of dedicated Agricultural Support Service experts and volunteers are committed to work for a better future by continuing to improve and develop environmental friendly products.
Global focus
Our goal is to extend our footprint and to promote great opportunities for those that are serious about the state of our planet. With equal access to resources, farmers around the world grow to become empowered individuals and managers of their own enterprises with the ability to chase their dreams, and use the tools they need to build the life they want.
NEMATODES, DISEASE, WEEDS
Plant-parasitic nematodes are of great economic importance. ... Their effects are commonly underestimated by farmers, agronomists and pest management consultants, but it has been estimated that some 10 percent of world crop production is lost as a result of plant nematode damage (Whitehead, 1998).
In 2009, soilborne pathogens were responsible for an estimated 10% of losses in vegetable crops. Though these soilborne pathogens and others are common, we know little about their genetics, making it difficult to develop control methods. Because fungicide use is not consistently effective, economical, ecologically desirable (due to environmental and worker exposure concerns), or commercially desirable (production of pesticide-free or organic crops can increase crop value by 30%), biological control and plant growth promoting agents should be considered key management components.
Weeds reduce the quantity and quality of Australia's agricultural, horticultural and forestry products, affecting both industry and consumers. It is estimated that weeds cost Australian farmers around $1.5 billion a year in weed control activities and a further $2.5 billion a year in lost agricultural production. The real cost of weeds to the environment is difficult to calculate, however it is expected that the cost would be similar to, if not greater than, that estimated for agricultural industries. This is not only true for Australia but for all cropping areas around the world.

From Idea to Reality: The Evolution of Exa Ag
June 9, 2017
Exa Ag started as an idea triggered by a presentation at the International Cover Crop Conference in Stellenbosch, South Africa in 2015. Two agronomists,with more than 60 years combined experience in crop health, came together and through trial and error, over a period of more than a year (through different seasons and different situations) developed a unique product that is already revolutionising the future of soil fumigation and plant health. A combination of food grade agricultural remedies with a unique synergy provides the grower with necessary nutrients with the added benefit of suppressing certain pathogens, certain weeds and certain nematodes. Experimental trials done by the University of Stellenbosch in 2015 and repeated in 2016 has proven 100% in vitro control of Rhizoctonia Solani, Fusarium lycopersici and Pythium ultimum. Extensive field trials on carrots has confirmed the laboratory results.
Effect on soil borne diseases
Dec 9, 2017
The highly accredited Disease Clinic at the University of Stellenbosch has done numerous in vitro testings of Exa-Lera against certain soil-borne pathogens. The results have been just short of spectacular. Exa-Lera showed 100% control against Ralstonia solanacearum and Verticillium dahliae. It is now safe to add these two pathogens to the list of diseases.
Glasshouse trial on Meloidogyne javanica.
March 16, 2019
Nemlab in Klapmuts, Western Cape, South Africa, did an extensive scientific trial with Exa-Lera. The objective of the trial was to evaluate the effect and possible mode of action of Exa-Lera for the possible control of root-knot nematode (Meloidogyne javanica) in soil on tomato (Lycopersicon esculentum L. cv Moneymaker) in the glasshouse. The conclusion of the trial was
that Exa-Lera can be administered 5 days prior to planting, as it did not show signs of phytotoxicity to the plants. This would however need to be tested under field conditions to determine the reaction of the plants to the product under field conditions.
Exa Lera™ shows good potential for the control of Meloidogyne javanica on tomatoes under glasshouse conditions. Current field trials are underway in Brits, Mooketsi and Pontdrif, South Africa to test for soil disease control on tomatoes under field conditions
LEGEND
T3 = 1.3 dichloropropene @ 100L/ha
T4 = Exa-Lera @ 7.5L/ha
T5 = Exa-Lera @ 15L/ha
OUTDOOR TOMATO TRIAL
From the laboratory to the field. Efficacy tested against Fusarium R3
Exa-Lera® was applied at 15L/ha through dripper lines 7 days pre-plant at one of the biggest commercial tomato growers in Pontdrift, Limpopo Province of South Africa. Right from week one there was notable differences in seedling vigour which continued up to the end of the crop. Fusarium R3 was 90% controlled on the treated rows with 80% crop losses in the untreated.
REGISTRATION
In August 2024 Exa-Lera was officially registered as a soil applied remedy at Act 36 of 1947
