San Jose Scale Management

Monday Apr 01, 2024

San Jose scale is a relatively easy pest to control, but a dangerous one to leave uncontrolled. After a few years of infestation, limbs and even entire trees can be killed if heavily attacked, and high percentages of the fruit can be infested. Large trees are most often associated with scale problems, because of the suitable habitat they provide and the difficulty of obtaining good spray coverage. However, young trees can also develop a scale problem surprisingly quickly. San Jose scale is a pest that is easily prevented, but hard to control if the populations have built up too much.
