CAPCA Adviser Advertorial: CheckMate® NOW-F Redefine Your Spray Program with Precision Mating Disruption

The Key to Navel Orangeworm Control

This information was first shared in the March 2025 edition of the CAPCA Adviser newsletter on page 59.

The consensus across California’s nut crop industry is that mating disruption is a 
foundational component of Integrated Pest Management (IPM) programs. Evidence shows that an early spray of CheckMate^® NOW-F may be the best way to implement mating disruption into your program. When applied as a spring mummy spray it 
provides extended action against the first flight of Navel Orangeworm (NOW) and later applications at hull split and beyond to protect your crops when they are most vulnerable. Growers looking for a precision timing approach to mating disruption can optimize their return on investment by spraying CheckMate^® NOW-F at least twice each season.  

Disrupting the First Flight Delivers Strategic Advantage.

In the sprayable toolkit, CheckMate^® NOW-F delivers the longest residual activity available on the market. A comprehensive case study from 2022 underscores this long residual action, with 98% trap suppression sustained over an impressive 2-month period following a late-April application. Applied in spring to target the first flight, it effectively disrupts mating until hull split.

Your Guide to Optimal Spray Timings 

A mummy spray applied in spring is the most effective timing for the first NOW-F pheromone application and should be a standard part of your program. Subsequent applications can be tailored to your specific crop timing and harvest schedule.

Maximum Benefit: Mummy Spray

Start your season’s NOW spray program off with the most effective mummy spray, CheckMate^® NOW-F, designed to target the entire first flight. 

With up to 8 weeks of mating disruption activity following spring applications, this program provides a solid start to your season, significantly reducing pest populations heading into hull split. 

Boost the effectiveness of later-season controls and set the stage for a healthier, more productive crop. 

Excellent Benefit: Hull Split Sprays 

Amplify your control by continuing your precision-timed mating disruption program at hull split. This builds on the strong foundation of pest disruption by extending protection during this critical stage. Hull split sprays provide up to 4 weeks 
of activity, ensuring excellent performance through every stage of hull split, regardless of coverage

Unique Benefit: Harvest Sprays 

With zero PHI and 4-hour REI, CheckMate^® NOW-F is the safest and most effective tool to control NOW around harvest operations. Applying at this time will ensure the protection of late shakes and pollinizers to maximize returns on all varieties and limit 
overwintering pest populations
