DIRECTIONS FOR USE
It is a violation of Federal Law to use this product in a manner
inconsistent with its labeling. Read and follow all applicable
directions and precautions on this label before using.
Fixed copper is one of the oldest fungicides and bactericides, used to
control a wide range of plant diseases. Soap-Shield is a patented,
fixed copper fungicide, made by combining a soluble copper fertilizer
with a naturally-occurring fatty acid. The copper and the fatty acid
combine to form a copper salt of the fatty acid, known technically as a
true soap. The copper soap fungicide controls many common diseases
using low concentrations of copper, down as low as 90 ppm. The net
result is an excellent vegetable, fruit and ornamental fungicide.
Soap-Shield decomposes to form soluble copper, and fatty acid, both of
which can be used by microbes and plants. Soap-Shield is suited for use
in domestic circumstances, both indoors and outdoors.
Soap-Shield controls diseases of a wide range of plants, including many
vegetables, fruit and ornamentals. As with most fungicides, Soap-Shield
acts to protect plants from infection. Therefore, it is important to
have Soap-Shield on the leaf, flower or fruit before the pathogen is
able to cause an infection.
A wide range of bacteria and fungi attack plants, however, they
generally only cause a few types of diseases. When using Soap-Shield,
it is important to identify the type of disease in order to use the
best method of disease control.
Powdery mildews tend to occur on the upper leaf surfaces, as
though a white powder was sprinkled onto the plant. Powdery mildews can
form a dense, white, cottony mass, making the whole leaf appear white.
They are also commonly found on stems. Powdery mildews rarely kill
plants. Most fungal diseases require water to infect plants. Powdery
mildews are unique in that they do not require water for infection.
Hence, under greenhouse conditions, powdery mildews can become severe.
Shade and dense plantings also promote powdery mildew. Powdery mildews
commonly occur on the following plants: apple, bean, beet, broccoli,
brussels sprouts, cauliflower, cabbage, cantaloupe, chard, chicory,
chive, cucumber, currant, endive, gooseberry, grape, grasses, hop,
kale, kohlrabi, lettuce, lilac, oak, pea, pumpkin, rose, rutabaga,
spinach, squash, strawberry, turnip, zucchini and many other plant
species.
Downy
mildews tend to occur on the lower leaf surfaces. Downy mildews
are much finer than powdery mildews, and appear as fine white cotton,
similar to duck down. Downy mildews can rapidly kill plant leaves
during wet, cool weather, but are inhibited by hot dry weather. Downy
mildews commonly occur on the following plants: bean, beet, broccoli,
brussels sprouts, cauliflower, cabbage, cantaloupe, chard, chicory,
chive, corn, cucumber, endive, garlic, grape, grasses, hop, kale,
kohlrabi, leek, lettuce, onion, pea, pumpkin, rutabaga, shallot,
spinach, squash, sunflower, tobacco, turnip, zucchini and many other
plant species.
Leaf
and fruit spots are small brown or black spots on the leaf or
fruit. They commonly occur on apple and pear (scab), as well as on most
of the plants grown around the home and in the garden. These spots can
be caused by a range of fungi and bacteria. Leaf and fruit spots are
commonly caused by fungi belonging to the following genera: Alternaria,
Cercospora, Colletotrichum, Cylindrosporium, Gloeosporium, Glomerella,
Gnomonia, Marssonia, Mycosphaerella (Didymella), Phomopsis,
Phyllosticta, Septoria, and Sphaceloma. Spots on leaves and fruit
can expand and grow together. Leaf spot pathogens require water to
infect plants. During wet weather, spots can develop into a blight, very rapidly, killing
leaves, flowers and stems.
Rusts
are small orange blisters that appear on plant leaves, and that are
full of orange powder. The orange powder is rust spores. Towards the
end of the season, black spores are often produced. Rust is commonly
found on grasses, currants and many other types of plants.
Fruit
rots commonly occur on strawberries, raspberries, and other
fruit. They appear as soft, rotten areas on the fruit. Often the causal
fungus can be seen growing and producing spores on the surface of the
rotting area. Rots are often caused by fungi belonging to the following
genera: Aspergillus, Botrytis, Monilinia, Mucor, Penicillium, Rhizopus
and Sclerotinia.
Application
Directions
Shake well before use. Most
conventional liquid pesticide plant sprayers can be used to apply
Soap-Shield to plants.
To control powdery mildews,
use a solution of 0.5 to 2.0 fluid ounces of Soap-Shield in a gallon of
water. For best control, start spraying before the disease is visible
or when mildew is first visible on the plant. Spray all plant parts
thoroughly, and repeat every 7 to 10 days. On plants that are very
susceptible to powdery mildew, such as greenhouse-grown cucumber, it is
best to spray the plants twice a week during the first 2 weeks after
emergence, and weekly thereafter. On outdoor plants, re-apply after
rain.
To control downy mildews, leaf and fruit spots,
blights, and rust, use a solution of 0.5 to 2.0 fluid ounces of
Soap-Shield in a gallon of water. Ensure that all surfaces of the plant
are thoroughly sprayed. For best control, begin treatment 2 weeks
before disease normally appears or when weather forecasts predict a
long period of wet weather. Alternatively, begin treatment when disease
first appears, and repeat at 7 to 10 day intervals for as long as
needed. Re-apply after rain. Use 2 fluid ounces per gallon of water,
sprayed every 7 days or less, following heavy rain or when the amount
of disease is increasing rapidly. This higher rate should be used for
preventing late blight on potato and related plants. If possible, time
applications so that at least 12 hours of dry weather follows
application.
To prevent fruit rots, use a solution of 0.5 to
2.0 fluid ounces of Soap-Shield in a gallon of water. Ensure that all
surfaces of the plant are thoroughly sprayed. Apply at the start of
flowering and continue every 7 to 10 days until harvest. Fungicidal
sprays are especially warranted when weather forecasts predict a long
period of wet weather. Re-apply after rain.
Cultural Method to Assist in Reducing
Plant Disease
Several common sense techniques can also be used to reduce plant
disease. These include:
• Inspect the plants often for signs of disease or
insect pests. Take appropriate measures when warranted.
• Promote healthy plant growth, but do not over
fertilize.
• Do not grow the same types of plants in the same
location in successive years.
• Control weed species around the garden that are
related to the plant species that you are growing. Weeds are a source
of plant pathogens.
• Space plants to ensure good airflow and drying
after rain. Also, water plants in the morning to minimize the time that
the plants are wet.
Wet leaves, flowers and fruit promote infections by plant pathogens.
• Prune plants during dry weather to avoid wound
infections.
• At the end of the growing season, remove and
compost all garden refuse. Garden refuse can act as a source of plant
pathogens.
