FOR CONTROL OF PEACH TWIG BORER
INSTRUCTIONS FOR USE
NoMate PTB Spiral is intended to prevent damage in stone fruits and nuts (peaches, quince, almonds, apricots, plums, prunes, nectarines, and cherries) caused by the peach twig borer. 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. Reduction in the use of conventional insecticides permits an increase in the populations of parasites and predators which assist in the biological control of other pests.
METHOD OF APPLICATION
NoMate PTB Spiral should be deployed in the upper one-third of the fruit tree canopy. The spirals should be placed at least 1-2 feet within the radius of the canopy. Scentry applicators are a convenient and economical means of placing the PTB Spirals in the upper canopy. The spirals may also be hand applied. Spirals placed properly are to be wrapped around a stem or branch, and are wind and rain fast. For maximum effectiveness, it may be necessary to increase the density of the spiral placement around the orchard perimeter.
TIMING OF APPLICATION
1. Monitor, using Scentry \"Wing Style\" or \"Large Plastic Delta Style\" traps and Scentry PTB pheromone lures to determine the time of application. Traps should be placed in the orchard a few days before blossom to determine biofix and the first flight. Change monitoring lures every 3-4 weeks.
2. Make the first application of NoMate PTB Spirals within 2 to 4 days after the first male moth is captured in a trap (biofix). Prediction Degree Day Models can provide assistance in determining application timing. Model information and economic thresholds that may vary according to geographical regions are available from your county Farm Advisor.
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. Peach Twig Borer life cycle models, diligent trapping, and field checking are all important considerations in the proper timing of an additional spiral application.
