Made from a combination of sulphur compounds, HAY GUARD enables you to start baling within a few days instead of waiting 4-6 weeks. Unlike proionic acid products, HAY GUARD has no odor.
Once applied to the cut hay, HAY GUARD turns into gas and searches for oxygen then it ‘eats’ up the oxygen in the bale, prohibiting microbial growth so the bales will stay cooler, and you’ll see less browning.
