A Case Study: Citrus Greening in Indian River County, Florida

posted in: Results Blog | 0

As many of you know, Citrus Greening (huanglongbing) is disease affecting citrus crops around the world. Over the last 21 years it rapidly became a major threat for farmers everywhere as it spreads across their holdings and systematically renders once fruitful groves essentially barren.

Back in the Fall of 2014

This is the story of Bobby Lindsey, a life long grower from Indian River County, Florida. After Citrus Greening spread across his home grove, it yielded minimal crops for 2 years. Seeing no recourse to his dire situation, the Bobby was forced to push over 15 of his 20 acres of trees due to the infection. This was in fall of 2014.

Our President and CEO, Ioan Hossu, and AGRO-Aid distributors, Alan Fickett and Aaron Morrison, assessed the situation and recommended 3 sprays of IHO-Bio across the remaining 5 acres. The crops were first sprayed in October and then again 24 days later.

December 2014

After just the second spray in December, the results were already promising. All the trees were full flush, the largest that the grower had seen in a long time; the leaves were visibly larger and more vibrant.

A third spray was completed in January 2015. With the results being so promising, in March Bobby Lindsey decided to expand the application of IHO-Bio to his other groves that were also affected by Citrus Greening.

During the visit, Florida Department of Agriculture collected leaf samples to be analyzed and the results presented below:

Lab Results:

Long: 80.2741

Sum 128.34 109.52
Average 32.085 27.38

Conclusion: Young leaves had lower HLB bacterial titers.

“These results indicate that the grove still has citrus greening present in the grove with younger leaves having a lower titer (levels of pathogen) present. From our visit, the overall health of the trees did look pretty good and the application of the products may have an effect to allow for the trees to better tolerate the presence of the pathogen”

Seeing is believing, the home grove tour speaks for itself !


28.5% Yield Increase without any soil fertilization.

Always reluctant to “count his chickens before they hatched” Bobby Lindsey is convinced that Florida citrus industry has a future. He becomes a strong promoter for IHO-BIO as excellent fertilizer and effective to fight citrus greening.
