codling moth infestation the following spring. Plan ahead!) .
Plant barriers and decoys can also be used. Grow a veceta}
flower preferred by a particular insect away from the garden to
attract it to another location. Place répéllant plants near a
vegetable or flower that needs protection.

You may also wish to plant some herbs in your beds for.
insect control. The age and number of plants used per 100
square feet determine the herb’s effectiveness. A young plant’
does not have an aroma or root exudate strong enough to dis-
courage harmful insects or to attract beneficial ones. Similarly, *
too few herbs will not control a pest or attract a needed predator.
Too many herbs may retard vegetable growth and vield. Com-
posite flowers, such as Pot Marigolds (Calendulas), are excel-
lent attractants for predatory insects because their large supplies
of pollen serve as predator food sources. A few (2-4) plants per
100 square foot bed will probably suffice. We have not donea
lot of experiments with them yet, however, since accurate test-
ing can take two to three vears for one herb grown with one
food plant to control one insect. This requires more time and
funding than we have. You may wish to try some of these biody-
namic observations though. It’s a lot of fun to try and see for
yourself!
