Steps

1
Select and plant resistant squash varieties such as Marketmore 76, Slicemaster, and Raider.
Tip: Using resistant cultivars is the first line of defense against powdery mildew.
2
Space plants apart properly to avoid crowding.
Tip: Increased spacing allows for better air circulation, which discourages fungal growth.
3
Eliminate weeds around the squash plants and the general garden area.
Tip: Removing weeds further improves air circulation around the foliage.
4
Rake and dispose of all fallen or diseased leaves and fruit in autumn.
Tip: This removes the source of fungal spores that could infect next year's crop.

Pro Tips

  • Air circulation is critical for preventing the onset of powdery mildew.
