New Pesticide for Greenhouses

May 22, 2002

Pylon is a new insecticide/miticide for use in greenhouses. Olympic Horticultural Products is responsible for distribution of the material. Pylon is in a new chemical class referred to as pyrroles. The active ingredient is chlorfenapyr. Pylon works as a contact and ingestion miticide by interrupting energy production. The material has translaminar activity, which means that the material penetrates leaf tissues and forms a reservoir of active ingredient within the leaf. This provides residual activity against certain foliar- feeding insects and mites. Pylon is labeled for mites (two spotted spider, broad, and cyclamen mites) and caterpillars.

Pylon can be applied with conventional application and low-volume application equipment. The rate range is 2 to 5 fluid ounces per 100 gallons. The restricted- entry interval (REI) is 12 hours. Pylon cannot be applied to vegetable transplants, and we suggest that you avoid applying it to plants in bloom as some phytotoxicity has been observed, especially on chrysanthemum flowers. In addition, do not apply Pylon more than two times during the crop cycle. In tests conducted at the University of Illinois, we have gotten over 90% control of two-spotted spider mite (Tetranychus urticae) for up to 28 days with Pylon.
