Horsehair Worms: Pest Notes for Home and Landscape

They occur in water sources such as ponds, rain puddles, swimming pools, animal drinking troughs, and even domestic water supplies.  Free.

Several Asterolecanium species of pit scales attack many  common deciduous and evergreen oaks in California. The valley oak is especially susceptible. Pit scales suck juices from twigs and cause twig dieback, which first becomes apparent in mid- to late summer. A severe infestation delays leafing-out for as long as 3 weeks in spring and heavy attacks year after year may kill young trees. Free.

Pitch Canker: Pest Notes for Home and Landscape

Pitch canker is a disease of pine trees that is caused by the fungus Fusarium circinatum. The fungus causes infections (lesions) that can encircle or girdle branches, exposed roots, and the main stems (trunks) of pine trees. The tips of girdled branches wilt as a result of obstructed water flow, causing the needles to turn yellow, and then red. Free.
