Leaf Spot
Fungal Leaf Spot
Strawberry Leaf Spot
Description
Leaf Spots can be of various colours - grey, brown or black (Roses in particular). The spots are in fact dead leaf tissue caused by the fungus which spreads the disease. Spots can sometimes join together to form larger areas of dead tissue. Some Roses also develop smaller black spots on stems.
Symptoms
There are few other symptoms than the spots themselves. However, diseased plants frequently have other problems causing weaknesses which enable the fungal disease to develop. It is worthwhile carefully checking any plant with Leaf Spot.
Treatment and control
General tips
Immediately remove and destroy all infected leaves and plant parts. Pick up any fallen foliage and destroy. To reduce the chances of re-infection for the following season, prune shrubs back hard.
Spray with suitable fungicides
For Roses and other ornamental plants, products with one of the following active ingredients will enable control although directions should be checked to ensure suitability for specific plants: RoseClear 3 and RoseClear 3 Gun! (contain bifenthrin and myclobutanil) or FungusClear Ultra (contains triticonazole). Continue spraying at fortnightly intervals throughout the season.
