Prevent Leaf Spot on your Plants this Spring!

Leaf spots are a common disease that affect the foliage of plants noticed especially throughout the colder seasons. Most leaf spots are caused by Fungi, some others by bacteria. Once the disease is in the leaf it will continue to grow until the leaf tissue is destroyed, with spots varying in size from pinheads all the way to pots that can take up the entire leaf!

There is no known cure for leaf spot so your best bet to combat this disease is through maintenance foliar spraying. This will prevent the spores from germinating and spreading. If your are not preventatively spraying then spray a Physan 20 solution at the first sign that symptoms start appearing.


Treating Trees, Lawn & Turfgrass from Leaf Blights and Leaf Spots (Also applies for Flowering dogwood (cornus florida):

Mix 2 tablespoons of Physan 20 in 11.3 Litres of water. Spray 4 times – when flower buds begin to open; as soon as flower bracts have fallen; 4 weeks later; and after flower buds are well formed. If possible, spray just before rainy periods.



Treating Hawthorn (crataegus) - Leaf Blights:
