Dormant Spraying
Dormant spraying is one of the easiest, most
effective of all the spraying you will do in a growing
season. Dormant disease control spray is lime sulphur.
Lime sulphur helps to prevent diseases from occurring
during the growing season by killing disease causing
spores that over winter on tree and shrub buds, twigs
and bark. These same spores can also over winter on
fallen leaves. Be sure to rake and dispose of leaves if
you know you have a disease problem.

Insect Control
For insect control, use Bonide Dormant Spray Oil or
Volck Oil. They are 97% petroleum oil. The oil will
smother insect eggs over wintering in the same places as
the fungal spores. These two products can be mixed
together at the rate of 5 tablespoons Bonide Dormant
Spray Oil or Volck Oil and 5 tablespoons Lime Sulphur
for excellent control of insects and disease. |

Prevention
Dormant spraying, true to its name, is applied when your
outdoor trees and shrubs are in their dormant stage. The
best time for application is in March and April before
the trees or shrubs begin to leaf.
When you spray, apply it to all branches, trunks and
ground area until the point of run-off. Be careful when
spraying around the house, sidewalks, etc., as the lime-sulphur
will stain.
Dormant spray can be applied to all trees, shrubs, rose
bushes and any other deciduous (leaf bearing) outdoor
woody shrubs.
We don't recommend dormant spraying for evergreens. The
oil can reflect the sun on your evergreens and cause
foliar burn. |

How Often
Spraying twice a year during the dormant season (spring
and fall) will greatly reduce the chance of having to
spray throughout the growing time.
Dormant spraying is one of the safest and economical
sprays available. |
