General Information

NoMate TPW Spiral is intended to prevent damage to tomatoes and other crops infested by tomato pinworm. The product functions by disrupting the mating communication between the sexes of the adult moths. By interfering with the natural mating process, fertile egg laying and subsequent larval infestation can be suppressed, thus reducing the need for conventional insecticides permits an increase in the populations of parasites and predators which assist in the biological control of other pests.

Limitations, Restrictions, and Exceptions


NoMate TPW Spirals is applied directly by wrapping the spiral around the stems, branches, stakes, wires and strings. Open the container just prior to application. Apply the product to the upper 1/3 portion of the canopy whenever possible. Also, the spirals should be placed with uniform field distribution.

For maximum effectiveness, it may be necessary to increase the density of dispenser placement around the field perimeter.

Un package and use only the amount of spirals to be used immediately.

Reseal partially used bags and return them to cold storage while awaiting later use.


1. Monitor, using Scentry “Wing Style” or “Large Plastic Delta Style” traps and Scentry TPW pheromone lures to determine the time of application. Trap placement should begin in March/April to determine first flight and should continue throughout the season to help assess treatment effectiveness. Change lures every 3-4 weeks.

2. The application of NoMate TPW should take place no later than two weeks after transplant (in tomatoes) or if traps capture 2-5 tomato pinworm moths per day. If thorough field monitoring indicates a low level of pinworm infestation, the application may be delayed until; economic thresholds are reached.

3. Second and any subsequent application should be timed such that the new application is made before the effect of the previous application significantly diminishes. Tomato pinworm cycle models, diligent trapping, and field checking are all important considerations in the proper timing of an additional spiral application.
