The following short account of the diseases and insect pests is not
intended to be exhaustive, and is only intended to refer to the raisin
districts of our State. I have not included accounts of the phylloxera
nor of other insects or fungi which do not exist in these districts,
but which may be troublesome in other parts of the State. Strictly
scientific descriptions have purposely been left out, but I have
endeavored to make the popular account as correct and as condensed as
possible. Of insects and fungi I have only enumerated those which are
of importance through the damage they occasion from time to time.
Those which prey on the vines, but which cause no great damage, and
which the grower need not prepare himself to fight, have here been
left out.
