Upcoming Webinars:
The Hidden Factors Affecting Spray Efficacy
Coming Soon!
Are your crop protection products reaching their full potential on the leaf?
Even when water quality and droplet size are addressed, other factors can still reduce efficacy.
Join this webinar as we unpack these key challenges and explore practical strategies to help improve spray performance in the field.
Watch out for the assessment link to earn CPD points – to follow shortly after the webinar.

About:
Water quality, its cations, pH, and buffering capacity, can significantly reduce the effectiveness of herbicides and insecticides. The good news? The right adjuvants can overcome these challenges and restore performance across most water sources.
Previous Webinars
Are spray water conditions reducing your product performance without you realising it?
In this webinar, Dr Brian de Villiers, adjuvant expert, explains how water quality affects spray efficacy, from mixing in the tank to droplet drying on the leaf.
He unpacks key factors like cations, pH, buffering capacity and turbidity, and shows how they influence absorption, compatibility and overall control. You’ll learn how to identify risks, adjust spray water correctly and use adjuvants to improve efficacy and protect your investment.
Spray Technology | Is Your Spray Hitting the Target?
Are you getting the most out of your spray application, or is valuable product being lost before it reaches the target?
In this first Spray Technology Webinar, Voltan Senekal, National Marketing Manager at Villa Crop Protection, takes you through the science and real-world realities of spray application. From nozzle selection to droplet behaviour, drift risk and penetration into the canopy.
This practical, data-driven session draws on insights from global research and field demonstrations, helping producers and advisors make better decisions to reduce spray losses, improve efficacy and protect return on investment.
Listen to the Podcasts:
In this video, you’ll find clear answers to questions like: Why should I add AMS to glyphosate sprays to improve efficacy? Can AMS replacements really match ammonium sulfate in overcoming hard-water antagonism? What exactly is “hard water antagonism,” and how does it block glyphosate uptake?
