79 WARRIOR® T INSECTICIDE: A NOVEL ENCAPSULATED FORMULATION. M. A. Zajac, S. H. Martin, L. S. Boykin, and D. Chaney, ZENECA Ag Products, West Lafayette, IN
Warrior® T is a novel encapsulated formulation (called Zeon Technology) of lambda-cyhalothrin. Warrior® T is a water-based, rather than solvent-based, formulation and as a result provides significant improvements over the 1 EC formulation in environmental and handler's toxicity. The capsules in Warrior® T were designed for the fast release of lambda-cyhalothrin to maintain the speed of activity of Warrior®. After application, the active ingredient moves rapidly out of the capsules: Within three to four hours, 90% of the active ingredient has moved outside of the capsule, while the remaining portion moves out within the first twenty-four hours. The capsules also contain an ultra-violet protectant which reduces photo-degradation of the active ingredient. Another unique property of Zeon Technology is the creation of a capsule that strongly adheres to plant tissue after contact, thereby ensuring excellent rainfastness. Significant improvements in environmental toxicity were also obtained with Warrior® T. The most significant improvements with the T formulation are in enhanced handler's safety and decreased superficial facial sensitization. All these improvements were achieved while maintaining the superior broad-spectrum insect control synonymous with Warrior®. Over 100 field trials have been conducted on a wide range of crops and pests to evaluate the efficacy of Warrior® T compared to Warrior® 1 EC and other insecticides. Analysis of these trials have demonstrated that Warrior® T provides equal to or slightly better insect control than Warrior® 1 EC.
