“I first used Tridectin as a summer drench in 2018 as I was happy with the combination of actives it contained”. Following this our local Virbac Area Sales Manager undertook a Faecal Egg Count Reduction Test which was analysed by Invetus Parasitology, it returned a result of 100% for Tridectin. Tridectin is now well and truly in my drench program. It will be my pre lamb drench as the 14-day persistency on barbers pole will give me some breathing space at lambing”.
