What you will see

Blossoms and shoots suddenly turn black and hang as if scorched, sticky white fluid oozes from the infections; sunken cankers form.

The source says: it can be devastating to pears.

When to look

From late spring to fall

How to protect

  1. Prevention
    • Watch out for warm, damp springs; do not over-feed with nitrogen.
  2. By hand once detected; prune in winter dormancyCut out the infection 11¾–23½ in below the visible damage, expose the bark and check for brown staining; disinfect tools after every cut; burn the material.
  3. By hand after the main floweringRemove late secondary blossoms before they open.

Pear psylla

Pear psylla

Cacopsylla pyricola
High riskpest

What you will see

Honeydew and sooty mold on leaves and fruit (fruit russeting); damaged parts of leaves turn black, leaves may yellow and drop. Eggs are tiny and yellowish, on fruit stalks and leaves.

The source says: it is one of the most serious insect pests of pears.

How to protect

  1. Prevention
    • Keep the population low all year – high numbers are hard to manage; reduce overwintering adults before egg-laying.
    • Do not use broad-spectrum insecticides – they destroy natural enemies.
  2. Biological the whole growing seasonEncourage lacewings, brown lacewings and Orius bugs (minute pirate bugs); natural enemies alone may not be enough.
  3. Gentle spray from leaf fall to the end of January/February (start of egg-laying)Horticultural oil in winter dormancy kills overwintering adults (not the eggs, but it lowers egg-laying for ~a month); apply from leaf fall to the start of egg-laying, in warm, sunny weather.

When to look

In summer and early fall

How to protect

  1. Prevention
    • Remove junipers (Juniperus) near pear trees.
  2. By handCut out cankers on juniper; cut out affected pear branches.

Fungicides are not recommended; no readily available fungicide effectively controls rust on edible pears.
