Field trials against citrus diaprepes weevil in Florida

Preparing Nemastim to ship to our partners at the USDA so they can conduct field trials in Florida orchards. It is a great pleasure to move forward with field trails after our successful greenhouse trails which prepared us to enter the greenhouse growers market to bring the first nematode pheromone to the market.


We are excited to help Florida citrus farmers to fight the invasive Citrus Diaprepes weevil which attack’s 270 plant species including citrus, sugarcane, strawberry,  potato, mahogany, ornamental plants, papaya and more.

Currently, we are raising our seed round to scale up our manufacturing.

A New Kind Of Pheromone To Control Agricultural Pests

Karl Cameron Schiller is the co-founder of Pheronym, a Davis-based agriculture biotech start-up using a new kind of pheromone from microscopic roundworms called nematodes to control agricultural pests. We asked him about his work.

How can nematode pheromones be used in agriculture?

The first use case, which is the closest to market, is called NemaStim for stimulating nematodes to disperse and kill insects. Treating beneficial nematodes with pheromones improves their effectiveness to control insect pests.  Keep Reading

Karl Cameron Schiller, Chief Operating Officer, Pheronym, will be speaking on biocontrol with nematode pheromones at the 4th Partnerships in Biocontrol, Biostimulants & Microbiome Congress: USA.

 Biotech: pheromone pest control, animal health innovation and more

Ag Biotechnology is a hot topic in the investment world, according to a report by Finistere Ventures, attracting more dollars than most other agtech segments. The category includes new breeding technologies, which Rabobank’s food and agribusiness research team reported on last year. According to the RaboResearch report, emerging techniques include CRISPR technology, which “allows for faster and more precise breeding.” Upcoming FoodBytes! Chicago pitch company, Spira, has modified the technology to enhance the flavor profile of spirulina as an ingredient, allowing food companies to incorporate the superfood into their products without sacrificing taste. Biotech alum, Pheronym, is utilizing pheromones from microscopic worms….. Keep Reading

There’s a bumper crop of ideas growing in Woodland—from measuring a plant’s water needs to fighting nefarious pests to streamlining markets.
He’s not the only one who made a transcontinental move. Pheronym, launched in Florida, settled in Yolo County to perfect its idea of using nematode pheromones as a means of pest control.”It was the right ag location, the right talent pool from UC Davis, and they had internships,” Fatma Kaplan, Pheronym chief executive and the technology’s developer, told the attendees, noting that AgStart has been a big help as well.“Two years ago, we had an idea,” Kaplan said. “Now, we have a proven technology.Keep Reading
