What is wrong with my Bradford pear?

Published: Thursday, June 26, 2014 at 13:41 PM.

Make sure that all the infected fruit on your Bradford pear is removed as well as any fruit that has dropped to the ground.  You will want to dispose of these in the trash and not in a compost pile.

This disease will not kill your Bradford pear but it will make it look unsightly.  As the diseases begins to progress you may begin to see leaves around the infection turning a black color and it can often be confused with fireblight, which is a deadly disease if left untreated.

Fungicides may be used on hosts in the spring to protect it when spores are dispersed from the juniper host (when the yellow ‘goop’ appears on the junipers and are starting to dry). Fungicides containing the following active ingredients are commonly used to manage this disease: Mancozeb, Chlorothalonil, Myclobutanil, and Propiconazole.

Planthoppers

Have you noticed a fuzzy white powder covering the upper stems of hosta, azalea and many other landscape plants that looks like a fungus? 

Try this experiment. Use a pine needle to poke the white fuzz on your plant. Surprise! Perhaps half a dozen white insects will suddenly hop off the stem in all directions. If you touch the white powder with your fingers, it will seem sticky. The white insects are juvenile planthoppers. While feeding on your plant, they excrete filaments of white wax in order to protect themselves from predators.

Planthoppers do little damage to their host plants. The female inserts her eggs into plant stems and the nymphs feed on young leaves but little injury is ever noted. If the appearance of planthoppers is objectionable on your plants, no insecticide is recommended. Just blast them away with a water hose and give a nearby spider or beetle a good meal.
