Powdery mildew is another fungal disease that is often described as a white powder on the leaves. Several cool humid nights and warm dry days in a row help promote the outbreak of this disease.

Spittlebug is an insect that will attach Yarrow. The insect produces protective foam that looks like "spit". The foam helps protect the insect from ultra violet light and predators and insecticides. Use a strong spray of water to wash the foam off ofthe insect. The resulting exposure to UV light will kill the insect and expose it to predators. A stronger spray of water may also remove the insect from the plant in addition to the "spit". AllGuard is an organic spray that naturally repels insects.

Coneflower:

Powdery mildew will also occur under the right weather conditions. Botrytis may also occur. May get brown dead areas as well as distorted leaves. These plants now get aster yellows.

Daylily:

Daylily leaf streak causes reddish spots with yellowish margins that often result in brown streaks down the center of the leaves. Usually this leaf disease does not cause the death of the plant. Fungicides and sanitation are helpful. Daylilies are very cold hardy.

When these plants are emerging from the soil and are growing vigorously — they are susceptible to frost injury. The frost injury often becomes infected with saprophytic fungi.


 

Coral Bells:

Coral bells get both fungal and bacterial leaf diseases. Apply ZeroTol Fungicide/bactericide to prevent coral bells from bacterial and fungal growth. BUY NOW.

Pseudomonas causes "reddish" brown spots that may cause the leaf to be deformed

Xanthomonas causes small brown angular to circular spots with yellow halos.

Anthracnose causes small brown spots

Botrytis causes large brown spots. In addition the plant is prone to sun burning when the plant is exposed to too much hot sun. The sun burning causes irregular bleached dead areas on the leaves.


 

Hostas:

Hostas are normally attacked by two insects and slugs.

Grasshoppers eat large irregular holes and black vine weevils eat notches in the edges of the leaves. Slugs eat small irregular holes. Use insecticides on the insects. Controlling the growing conditions is more useful for slugs (keep plants on dry side minimizes use of mulches). AllGuard Organic spray is the answer to eliminating grasshoppers. BUY NOW

Anthracnose, sun burning, and drought stress are the other problems. Anthracnose causes brown lesions that may spread to encompass entire leaf. Sun burning often bleaches (light tan to whitish) the leaves. Drought stress usually causes dead leaf margins that may become infected with saprophytic fungi. Anthracnose usually causes brown spots on the leaves that can merge to form irregular dead areas and occurs more often on hostas in wet or over watered locations.  ZeroTol Fungicide/Bactericide is a very effective way to control ANTHRACNOSE on trees and ornamental shrubs. It is an ALL natural product that is safe for the environment. Buy Now BUY NOW
