Control Insects While Curbing Resistance

It is a constant balancing act—protecting this year’s crop while making sure the chemistries that are chosen will still be effective in future growing seasons. You have to know which products work best for your particular pest pressures, and how best to use them for maximum, sustained efficacy. Cormoran Insecticide was developed in response to pome fruit growers’ need for an excellent insect control product with an eye to future productivity.

Employ Multiple Modes of Action

When any insecticide is overused, there is a chance of the targeted insects developing resistance to that particular chemistry. That is why rotating products from different insecticide groups (i.e., modes of action) help prevent insecticide resistance and preserves the effectiveness of all the products being used.

Cormoran is an optimized ratio and formulation of the active ingredients novaluron (IRAC Group 15) and acetamiprid (IRAC Group 4A). The dual modes of action offered by the two active ingredients in Cormoran can help maintain the efficacy of other control options.

Cormoran is pre-mixed to deliver an optimum ratio and formulation of both active ingredients. This takes the guesswork out of mixing, with fewer rate and mixing errors, while providing an excellent rotational product to help prevent insecticide resistance.

Target Most Damaging Life

Stages of Insect Pests Cormoran is a foliar-applied, broadspectrum insecticide that controls codling moth, leafrollers, pear psyllid, thrips, leafhoppers and more in pome fruit. Its unique ovicide/larvicide combination kills eggs laid both before and after application.

By providing fast knockdown and long-lasting residual control for more than 14 days, Cormoran kills most damaging life stages of targeted insects and prevents outbreaks.

Best Practices for Using Cormoran

Now on the market for several years, Cormoran has become a tried and trusted rotational partner for apple and pear growers. Here are some of their tips for maximizing the benefits of Cormoran:

• While the label allows for flexibility in the timing of application, ADAMA recommends applying Comoran at petal-fall and continuing through the first generation of codling moth. However, to minimize the possibility of transient effects on honeybee brood development, do not use Cormoran on blooming crops when bees are actively foraging.

• The label range for Cormoran is 21-28 fl oz/a but ADAMA recommends using the mid to higher labeled rates to maximize efficacy and residual control. Use enough carrier volume to get good coverage.

• Calibrate spray equipment to target the right area, and check calibration frequently.

• Operate spray equipment at proper ground speeds, adequate spray pressure and spray volumes that assure the air volume within the tree canopy is completely replaced by the output from the air-blast sprayer, resulting in adequate coverage of the target crop.

• If orchards have been historically infested with mites or aphids, be sure to scout regularly and use miticides to control their populations.

• And, of course, always read and follow label directions.
