Website Video Featured Image - Dr Kerry Harrington Video Weed Control Masterclass

A few years back, we teamed up with weed science expert Dr Kerry Harrington from Massey University to film a live session at Central Districts Fieldays in Feilding. The goal? To give farmers a practical, science-backed guide to tackling stubborn weeds without sacrificing valuable pasture.

While that live event may be in the rearview mirror, the insights, strategies, and the masterclass page itself are still completely valid and available to access right now. https://www.redback.co.nz/weedseminar/ 

Whether you’re dealing with ragwort, thistles, buttercup, pennyroyal, or other persistent pasture weeds, this free video masterclass gives you the tools and know-how to take control and keep it.

Hosted by Redback Agri, this practical session covers:

  • Key pasture weed species and their seasonal behaviour

  • Why blanket spraying isn’t always the answer

  • How using a weedwiper can preserve clover while targeting problem weeds

  • Best practice tips for application timing, technique, and setup

  • Real-world results and farmer-focused advice

Dr Harrington’s decades of research into weed management and herbicide application (including in-depth studies on weedwipers) mean these insights remain standard practice for smart pasture management.

Alongside the video, you can still get the downloadable handout with all the key takeaways — ideal to keep on hand for reference during the upcoming spraying season.

If you’ve been wondering “How do I get on top of weeds without damaging good pasture?” — the answers are all right here.
