"I've been using Isomate since 1993. They're methodical in their research and field development—steps ahead of their competitors. They earned my respect and confidence when their executives came into our fields to learn from us while developing their products."

– Patrick McKenzie

Research shows

In orchards treated with Isomate CM/LR TT, weekly trap counts of Obliquebanded Leafrollers decreased by 70-100% compared to both untreated orchards and those treated with insecticides.

Similarly, Isomate® CM/LR TT treatment reduced weekly trap counts of Three-Lined Leafrollers by 67-100% relative to both untreated and insecticide-treated orchards.

Leafroller damage declined in 4 of the 5 organic orchards, and in 12 out of 15 Orchard-years, damage was less than 5% at harvest under Isomate CM/LR TT treatment.
