BioSafe Systems' Late Blight Program

Immediate / preventative measures for conventional and organic crops

If there has been a late blight warning in your area you should prepare for an outbreak; if you have seen the tell-tale signs of the pathogen on your on field you must take immediate action in order to control it. Because late blight spreads so easily during only moderate temperatures, slight wind and splashes of rain it can devastate a crop very quickly.

It’s important to treat early and often to be proactive vs reactive because the longer you wait, the more expensive it gets – both in loss and treatment.
