This week Lindcove REC is performing the annual citricola scale counts, to determine what type of treatment is warranted this year, if at all. Some San Joaquin Valley citricola scale populations are known to be resistant to Lorsban, an organophosphate pesticide. Other treatment options are available, such as using softer pesticides that are less lethal to natural enemies. One hundred leaves are plucked from each block, and healthy first instar nymphs are counted under a dissecting microscope.
