introduction
Downy mildew is one of the most widespread and destructive plant
diseases, impacting a wide range of crops worldwide.Farmers and agricultural
researchers continue to study this disease to develop more
effective management strategies and resistant crop varieties, as it
remains a persistent threat to global food security and agricultural
sustainability Downy mildew is a pervasive threat to agriculture,
primarily due to its ability to adapt to various environmental
conditions and its high reproductive rate.Recent studies
emphasize the role of climate change in exacerbating the
prevalence of this disease, as warming temperatures and shifting
humidity patterns create new hotspots for outbreaks.These
pathogens are obligate parasites, meaning they require a living host
to survive and reproduce.
