LATE SEASON APPLICATIONS
It’s Not Too Late!™ Late Season Applications of CIDETRAK® NOW MESO™ Can Provide Great Current and Future Benefits to Growers
Danielle M. Kirkpatrick, Ph.D. and Bradley S. Higbee
Hull split is imminent and exposes the almond crop to the threat of navel orangeworm (NOW). However, a late season application of CIDETRAK NOW MESO applied in July is not too late to apply in almonds to still have an impact. When comparing the timing of a full season mating disruption application with late season applications in May and July, the data showed that late season applications reduced damage to levels of 2.5 and 3% from 6 and 8%, respectively.
CIDETRAK NOW MESO provides season-long control of NOW through post-harvest and should have an influence on the next season as well. A full season mating disruption application provides trap suppression through post-harvest. A late season application should provide the same level of trap suppression, and reduced captures of NOW males per week in traps. Late season application of mating disruption may also influence the infestation of mummy nuts by suppressing mating in the later generations and preventing larvae from infesting mummies. Reducing the infestation of mummies, combined with proper sanitation methods, will reduce the NOW risk for the following season.
CIDETRAK NOW MESO based mating disruption formulation has been shown to reduce damage levels from 50-80% in replicated trials. This provides a much better return on investment (ROI) than the stock market, for example, or most other agricultural investments. However, every grower, and for that matter every orchard, may achieve a different NOW pest management result due to many different variables. So, an econometric model considering the investment in CIDETRAK NOW MESO “applied” cost will provide a good guideline for almost all growers. Assuming an estimated 65% reduction of field damage plus processing loss, a late season application of CIDETRAK NOW MESO applied in July provides a large ROI dollar value per acre. At field damage percentages of 2%, late season applications provide an ROI of 24%, and up to as much as 210% ROI at field damage levels of 5%.
A high potential ROI is the reward that may be realized from late season applications even at estimated low damage potential. Every grower should carefully consider installing CIDETRAK NOW MESO through July of this year to optimize their profitability, and in some cases to avoid a disaster.
