Cotoneaster infestation and shrub death

Oystershell scale on cotoneaster is widespread in Scarboro. Many twigs and bushes have succumbed to the infestation: looking closely at the twigs you will see what looks like small scars: this is the scale. The female scale dies in cold weather, but adheres to the twigs to protect the eggs through the winter. Spraying can work in early June on young “crawlers”, but it is more effective and cheaper to prune off the infected branches right down to soil level. Remember shrubs on the boulevard belong to the city – so call 311.
