Who We Are

For the Stoller Group, it has always been about being laser focused on conducting extensive research and development to create technologies and products to maximize the genetic expression of plants. That’s why, for more than 50 years, the Houston, Texas-based company is regarded as a worldwide leader in plant physiology, plant nutrition, and plant hormone technology.

Founded in 1970 by Jerry Stoller, the Stoller Group’s vision is widespread, as in worldwide spread. The company is now comprised of 16 wholly owned subsidiaries and has agronomists and scientists assisting farmers in 70 countries.

When the Stoller Group began, it’s focus was on producing chelated micronutrients. The company also began studying the production habits of 70 crops worldwide with the intention of improving production through its technology. For instance, in 1979, the Stoller Group introduced an innovative flowable sulfur product to control a broad spectrum of insects and diseases.

In the 1980s, the Stoller Group focused its research and development on understanding nutritional deficiencies and their precise time of impact on plant production. During this time, the company brought to market some of the most advanced chelated microelements available. It also debuted Nitro Plus, which increased nitrogen uptake and nitrogen-use efficiency for immediate root flush.

The 1990s brought more plant health innovation, as the Stoller Group extended its research and development into vegetal hormones to combine with nutrients to increase disease resistance. The company began experimenting with and researching the genetic expression of plants. Early in the decade, the Stoller Group introduced Stoller’s Stimulate, transforming the industry with a product composted of three phytohormones. Throughout the 1990s, the Stoller Group strengthened its reputation as a multinational company focused on plant physiology and as a pioneer in the physiological management of crops. One of the decade’s highlights occurred in 1998, when Ernst & Young presented Jerry Stoller with its prestigious “Entrepreneur of the Year” award.

In the 2000s, the Stoller Group focused its research and development on biologicals such as bioregulators and organic inoculants. The period was also marked by independent research verifying the success of the company’s products. In 2003, a Texas Agriculture Experiment Station Study showed that plants treated with the Stoller Group’s technology naturally improved their resistance to insects. In 2004, independent research confirmed that tomato plants treated with Stoller Root Feed produced 30-60% higher yields. The company also released data in 2005 showing its Bio-Forge product increased the survival rate and yield potential of stressed crops.

The Stoller Group’s success in the 2000s was reflected in its growth – in 2006 the company opened a 55,000-square-foot production facility in Houston.

The following decade, the Stoller Group made headlines with its overseas expansion. It invested R$30 million in a new factory for biopesticides in Cosmópolis in the Brazilian state of São Paulo. The factory, spread over 6,000 square meters, consolidated one of the biggest and most modern factories of biological products for agriculture in the world.

In 2020, the company opened Stoller Europe in Alicante, Spain. In 2021, Stoller Europe announced development of new techniques and innovative tools in the cultivation of olive trees to obtain Halkidiki olives, while reducing the effects of climate change on crops. These advances allow the fruits to have an optimized size and an improvement in the final texture, increasing their firmness and hardness.

Today, the Stoller Group holds several patents throughout the world for exclusive products. The company employs 15 Ph.Ds, who operate about 350 trial programs in universities across the globe.

Moving forward, the Stoller Group’s mission remains the same: It continues to research and develop innovative technologies in its never-ending quest to help farmers grow better crops.
