AGAIN we use the alphabet to list some trees, shrubs,
vines, flowers, and vegetables rather commonly
grown in home gardens; under each is a highly selective list of enemies
with suggestions on control. For amplification look back in Chapter II,
where you will find all the types but not all the specific pests.
In choosing the plants and pests to include in this all-too-brief list, I
have tried to give those representative of different parts of the country
and those I commonly expect to find in visiting home gardens. There
are many other possibilities. Again I refer you to the Gardener's Bug
Book and the Plant Disease Handbook as well as to the books given in
the Bibliography.
