Powdery and downy mildew are two of the most destructive diseases in global viticulture, attacking leaves, shoots and grape clusters and forcing growers into intensive, season‑long spray programs. They don’t just cut yields – they also erode berry and wine quality, driving up production costs and putting pressure on sustainability goals across wine regions worldwide. In Australia alone, powdery and downy mildew are estimated to cost the grape and wine sector about A$140 million per year. Why Powdery and Downy Mildew Are So Hard to Combat • Current preventative fungicide programs require intensive applications, resulting in high costs. In California grape production, powdery mildew alone racks up over 90% of the environmental burden from pesticides used to control this single disease •  Non-synthetic control strategies have been developed – such as botanical oils - but have proven to have questionable efficacy, especially when disease pressure is high. • Breeding for resistance varieties is a target strategy for control, but breeding programs can take years – and adoption even longer. Not to mention, new cultivars face the hurdle of building a consumer following over years of demand for traditional favorites. • Consumer expectations for sustainable, planet-friendly wine production are becoming a given, not just a ‘nice to-have.’ How Micropep is Approaching the Problem At Micropep, we believe peptides are a key part of the answer. Our technology harnesses the power of short, natural peptide sequences to precisely modulate plant and pathogen biology – opening the door to highly targeted, residue‑free disease control. By designing peptide‑based solutions that interfere with critical mildew pathways, we aim to give wine grape growers new tools that are effective, scalable and compatible with premium‑quality wine production. Our vision: vineyards where powdery and downy mildew are managed with a new generation of planet-friend precision tools — helping to protect yield, preserve wine quality, keep traditional cultivars in production and support the long‑term sustainability of the global wine industry. #viticulture #powderymildew #downymildew #Micropep #AgInnovation #SustainableAg
