Cedar rust

The cedar-apple rust disease is active during rainy periods. It is usually done for the season around Memorial weekend. Susceptible apple and crabapples are treated with a fungicide like myclobutanil to protect leaf and fruit tissue. This disease rarely harms the juniper or cedar so protective treatment for those plants in July is not suggested.

Grape Harvest

My Reliance grape is reaching maturity. It has two disease issues. Anthracnose which are the "bullseye" lesions on the fruit and black rot which makes the dried up or raisin like fruit. Protective fungicide sprays along with cultural practices are needed to manage these diseases. See Extension publication Fruit Tree Spray
