We sit down (again) with Kyle Okke of Agile Agronomy and explore how to make variable-rate residual herbicides actually work, from nozzle physics to dual-tank setups, and why agronomy must lead every tech decision. We also talk PWM (pulse width modulation), drift control, and mapping weed hot spots for smarter applications.
Additionally...
• Limits of conventional pressure-based rate changes
• Why droplet size, pattern, and drift control matter
• PWM and duty cycle basics
• Turn compensation for consistent coverage
• Mixing residuals with post products without losing efficacy
• DIect injection timing challenges at boom length
• Dual-tank, dual-boom systems for split strategies
• Cost and scale drivers for adoption of certain spray systems
• Green-on-brown paired with variable-rate residuals
• Drone mapping kochia and wild oat patches for targeted residuals
• Reducing passes, resistance pressure, and carryover risk
Stick around for the final part of our discussion, part 3!
