Key Takeaways
- BioWorks has launched TotalNema Ax, a 25(b) botanical nematicide formulated with a proprietary blend of botanical oils, designed to control plant-parasitic nematode populations through direct contact.
- The product targets outdoor specialty crops including potatoes, onions, strawberries, and leafy greens, reducing yield loss, stunted growth, and wilting from nematode damage.
- Field trials showed an 83% control rate against root-knot nematodes on cotton at 96 hours post-treatment, versus 44% for a competitive product; potato trials showed an 80% reduction in vascular ring symptoms and a 22.5% increase in total yield.
- TotalNema Ax carries a 0-hour REI, no PHI restrictions, and is exempt from maximum residue limits, supporting operational flexibility across pre-plant broadcast, in-furrow, drip, and drench application methods.
- As a 25(b) exempt botanical product, TotalNema Ax offers growers a sustainable, flexible alternative to traditional chemical nematicides, with low use rates covering large acre volumes.
BioWorks Launches TotalNema Ax Botanical Nematicide for Specialty Crop Growers
BioWorks, a provider of biological crop protection and plant health solutions, has introduced TotalNema Ax, a 25(b) botanical nematicide formulated to control plant-parasitic nematode populations in outdoor specialty crop systems. The product uses a proprietary blend of botanical oils to disrupt nematode respiratory systems and cause paralysis through direct contact, targeting the yield loss, stunted growth, and wilting that nematode damage causes in high-value crops including potatoes, onions, strawberries, and leafy greens.
BioWorks Field Trial Results: 83% Control Rate and 22.5% Yield Gain
BioWorks has published trial data supporting TotalNema Ax's efficacy across multiple crop and pest scenarios. In a root-knot nematode trial on cotton, TotalNema Ax achieved an 83% control rate at 96 hours post-treatment, compared to 44% for a competitive product. A potato trial measuring vascular ring symptoms associated with Verticillium infection showed an 80% reduction following treatment. In a third potato trial focused on early die complex management, crops treated with TotalNema Ax recorded a 22.5% increase in total yield. Full trial results are available on the TotalNema Ax product page.
“We're really excited to offer specialty crop growers a flexible, effective, sustainable approach to manage plant-parasitic nematodes and protect yield,” said Chris Rose, General Manager at BioWorks.
Operational Flexibility and Regulatory Profile
TotalNema Ax carries a 0-hour re-entry interval (REI) and no pre-harvest interval (PHI) restrictions, and is exempt from maximum residue limits. Application methods include pre-plant broadcast, in-furrow, drip, and drench, at low use rates designed to cover large acre volumes. The 25(b) exempt status positions TotalNema Ax as part of BioWorks' expanding open-field crop portfolio, extending biological and botanical solutions into conventional specialty crop production systems.
