A separate set of demonstrations in Modesto during 2018 evaluated the use of Cidetrak NOW Meso in ~25 acre orchards. Across all three varieties, male captures were reduced by 96.4 percent and damage was reduced by 60-90 percent at the center of each plot, although overall NOW nut damage was less than 1 percent. Economic Analysis of Data Economic analysis of data from all research trials showed that mating disruption typically paid for itself. This was due to a decrease in yield losses from damaged kernels, and due to improved quality assessments that define price premiums at the huller. As an example of how this worked, imagine a 2,500 pound per acre conventional orchard with 3 percent damage. The grower might typically receive $2.79 per pound ($2.75 base price plus a $0.04 cent bonus) for a total value of $6,875 per acre. If damage were reduced by 50 percent (typical for mating disruption), the grower would now have 1.5 percent damage. The grower would get paid for another 37.5 pounds of undamaged kernels, and the entire load might receive $2.89 per pound ($2.75 base price plus $0.14 bonus) for a total value of $7,333 per acre. This is an increase of $358 per acre, which is two to three Continued on Page 20 18 Organic Farmer October/November 2019
