Trident Biological Insecticide

We return Trident, our Bacillus thuringiensis var. tenebrionis bioinsecticide to the market to assist growers in the Great Lakes, Northeast and other potato growing regions who have resistant CPB populations and to help minimize the development of resistance in the more than 27 states where potatoes are commercially grown.

Trident is NOP Approved and OMRIŽ Listed to provide greater options for organic producers, who currently have limited insecticidal options. It has a four-hour REI and zero-day PHI, and minimal PPE requirements. Trident is residue exempt, which allows growers flexibility in their applications and better management of Maximum Residue Limits (MRL).

Application

Make your first Trident application as soon as eggs begin to hatch. Trident is most effective on young larvae, in the first and second instars or up to 1/4 inch in length. Trident attacks the larval gut and must be ingested by the insect to be effective. Thorough plant coverage is essential for best results. After eating Trident, larvae stop feeding within a few hours and die within two to four days.

Reapply every 7-14 days as necessary to maintain control during periods when larvae are present, as part of a pest management program that includes close scouting. During periods of heavy infestation and extended egg hatch, reapply every 4-5 days.

If infestation consists mainly of older larvae and adults, use a contact insecticide with rapid knockdown activity that is labeled for such use.
