What are the most effective PHEROCON® NOW monitoring lures to use to accurately predict NOW populations and damage?
The most sensitive lures are the PHEROCON NOW L2™ pheromone and the PHEROCON NOW L2 + PPO-HR L2 combined. However, in a MD orchard, studies conclude that no individual lure or trap type is a particularly powerful predictor of damage on its own. The best measure of damage prediction is when all types of lures and traps are used in conjunction with early split monitoring in almonds to increase the power of information generated.
What is the difference, and benefits therein, between PHEROCON VI Delta and PHEROCON 1C Traps?
There are two considerations when deciding which trap best fits your needs: the amount of labor required to service each trap and the total number of moths captured. The PHEROCON VI Delta Trap takes less time to service but captures fewer moths. Comparatively, the PHEROCON 1C Trap takes more time to service but captures a greater number of moths.
What happens if CIDETRAK NOW MESO™ strips fall out of the canopy? Will they get stuck in machinery and break machinery/processing equipment?
MESO™ strips must be applied in the upper 3rd of the tree canopy, on secure and thick branches during deployment. Following this strategy, the MESO strips should not shake out during harvest. However, they should not get stuck in machinery or break any equipment if they do. In the past several years, with thousands of acres deployed across California, this has not been an issue.
Can I just install CIDETRAK NOW MESO strips only in the barriers of my orchard and leave the centers MESO free?
Unless it a very small orchard (5-10 acres), this approach is likely to leave a large pheromone void in the center of the orchard which will result in increased mating and higher damage.
wHAt is the labor cost estimate for deploying CIDETRAK NOW MESO?
The estimated labor cost for a labor crew to deploy CIDETRAK NOW is about 4-5 acres per man-hour.
What Returns on Investment (ROI) can growers anticipate with CIDETRAK NOW MESO?
Assuming a market price for Nonpareil almonds at $2.00/lb, a grower can expect to recoup their investment from purchasing CIDETRAK® NOW in a 1% NOW damage scenario, assuming a 65% reduction of the in-field NOW damage. In a 2% NOW damage scenario, a grower is expected to receive a 19% ROI. As the in-field NOW damage increases, so too does the growers ROI. For example, in a high damage scenario of 5% in-field NOW damage a grower can expect to receive a 198% ROI due to the NOW damage reduction caused by CIDETRAK® NOW!
