About Us

The history of Agro Research International begins many years ago in Colombia. As part of a US, Canadian and Colombian initiative, I helped farmers transition from growing coca for illicit drugs to legal and profitable crops. One crop stood above others: Stevia, the natural sweetener.

I began testing and developing a number of products such as seaweed and natural essential oil extracts with fungicidal, bactericidal, insecticidal and nematocidal properties. Thyme Guard was that product and soon became a hit. The initial focus was tackling citrus greening in Florida, which was devastating the citrus industry. A trial with Thyme Guard at Mid Florida Citrus Foundation proved very successful, resulting in an increase in yield of 46%, primarily due to a reduction in fruit drop. This caught the attention of growers, and soon thereafter the University of Florida, in conjunction with CRDF, was studying Thyme Guard as a potential solution for the disease. 

Today, Thyme Guard has become and is recognized as one of the most important ingredients in the fight against HLB and also the most effective product to fight PFD in citrus crops and many other diseases in all crops from Powdery Mildew, Fire Blight to Fusarium and everything in between. More recently, the banana industry endorsed Thyme Guard to control probably one of the most devastating fungi, Fusarium 4th generation, also called the Panama disease, and also for control of black sigatoka.

In 2015-16 we went into full product expansion mode with the introduction of Kyte Gold, a patented liquid chitosan solution with biologics to help increase SIR elicitors for plant health. Then, a full line of biological soil amendments was developed under the Agro Gold family name with the concept of proven unique blends of synergistically developed Bacilli and other microorganisms to regenerate the soil and improve overall plant development.

In 2019 to close the loop for all the pesticides, we launched a new insecticide for organic crops, Agro Pest, a very effective solution to most sucking insect problems.

I am proud of our diversified and unique team who is at work every day trying to find and develop sustainable solutions to grow more and better quality food using as few resources as possible to feed an ever-growing worldwide population, while leaving small footprint as possible.

Lastly and most importantly, Agro Research International’s rapid expansion could not have been possible without you, the farmers on this continent and all 16 countries around the world where we are present who trusted our recommendations, tried our products and saw incredible results season after season.

I profoundly thank you.
