Kemin Launches TetraCURB, a New Organic Miticide

Kemin Crop Technologies has launched TetraCURB Organic, a new foliar spray miticide and repellent for use on all crops. TetraCURB Organic is listed by the Organic Materials Review Institute (OMRI) and provides a new option for organic growers to manage mite pressure throughout the growing season.


“TetraCURB Organic is our first OMRI-certified organic product in our crop protection portfolio,” says Marsha Bro, General Manager of Kemin Crop Technologies. “Due to the increased demand for organic food, fruits, and vegetables, the North American biopesticide market continues to grow. We want to offer new organic solutions for commercial growers to limit crop loss due to unavoidable pest infestations.”

Kemin Crop Technologies formulated TetraCURB Organic, a unique blend of botanical oils — including rosemary oil extracted from Kemin’s proprietary lines of rosemary plants — with active ingredients in high concentration. It is an emulsifiable concentrate that works on contact to effectively control target pests during the nymph and adult phases of their life cycle.

With the smart power of its unique blend of oils, TetraCURB Organic quickly knocks out spider mites with multiple modes of action, which contribute to the management of pesticide resistance development. When used according to the label, it offers a zero-day pre-harvest interval, a zero-hour re-entry interval, a broad crop application, no phytotoxicity on crops, and no Maximum Residue Limits concerns. TetraCURB Organic is a tool for organic growers to rotate into their integrated pest management programs.

“Concern about increased resistance in pests, the need for an organic biopesticide that has significantly fewer residues on crops, and the safety of workers and final consumers were the major drivers in the development of TetraCURB Organic,” says Emily Fuerst, Research and Development Director of Kemin Crop Technologies. “In Kemin trials of the product, we have seen a significant reduction in mite counts per leaf in high-pressure infestations on specialty crops such as tomatoes. Additional field trials are in progress with universities and other horticultural partners to generate additional data on the product performance.”
