19 May 2026, Victor: BioWorks, a leading provider of biological crop protection and plant health solutions, announces the launch of TotalNema A_x, a 25(b) botanical nematicide designed to effectively prevent yield loss, stunted growth and wilting from nematode damage. TotalNema A_x supports commercial production in outdoor specialty crop systems including potatoes, onions, strawberries, leafy greens, and other high-value crops. 

TotalNema A_x controls plant-parasitic nematode populations through direct contact, disrupting respiratory systems and causing paralysis.
