Double your protection-double your benefit...

We are quickly heading into harvest, and as we make our final sprints to the finish line of this growing season, it’s more important than ever to keep our trees healthy. Healthy trees mean healthy yields and healthy margins for our farms and operations.

For tree nut growers like yourself, because you have permanent tree plantings, the health of your trees as they complete the growing season can impact how your trees perform next year. 

Through this critical protection time, I believe the best tool you can have in your toolbox is our broad-spectrum biofungicide, Double Nickel®. With five modes of action, Double Nickel packs a powerful punch in controlling diseases such as bacteria canker and brown rot. Our potent formulations are doubly effective against foliar diseases even at low use-rates. Low use-rates equal cost savings as end-of-season treatments welcome the harvest.

Another advantage that everyone loves with Double Nickel is its flexibility. With two formulations, Double Nickel 55 and liquid-concentration Double Nickel LC, your tank-mix combination goals are met with the winning formulas of Double Nickel. And because Double Nickel is OMRI-Listed® and NOP-Approved, you can use it if you are growing organic, conventional or both.

Harvest is a busy time for us all. You have to walk a tight rope in ensuring you can protect against all threatening pests and diseases, plus meet your harvest goals. Double Nickel has your back in all these endeavors with the following critical benefits:

  • It can be safely tank-mixed with other fertilizers, insecticides, herbicides and even conventional chemistries, meaning you aren’t making multiple applications, saving time and money in this critical time. 
  • The use of Double Nickel won’t lock you out of your orchards during harvest. With a 4-hour re-entry and a 0-hour pre-harvest interval, you can get your harvest teams back to work quickly after application. 
  • Lastly, when you are applying many different products, and especially as you try to end the season strong, vigilance is key in preventing resistance. Double Nickel brings five modes of action to your spray tank, which fights your chances at developing resistance. 
  • Immediately following harvest, preparation for the next growing season begins and Double Nickel can be an integral part of your post-harvest chores. Adding Double Nickel to your chemigation provides effective root protection at low rates. In fact, the active ingredient of Double Nickel LC is a naturally occurring strain of a beneficial bacterium that colonizes and protects young roots.

Remember that the Certis Biologicals team is always here for you during times when crop protection kicks into high gear. Harvest is no exception. If you want to incorporate Double Nickel into your IPM or if you have questions about how to maximize Double Nickel in your pre-harvest applications, please reach out to us at

We look forward to finishing out 2021 strong with you!
