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.
