Hose end
sprayers are the simplest and least expensive of the category. A sprayer
jar is attached to a regular garden sprayer. Concentrated material is
added to the sprayer jar. An adjustment on the jar determines the amount
delivered. The force of the water through the hose pulls the material
up from the jar and mixes and dilutes it with the water. A built-in anti-siphon
device prevents unused material from being pulled back into your water
supply.
Compression or tank sprayers are the most common type of spray equipment. Concentrated
material is added to the tank. Water is then added to a marked fill line.
The remaining air is pressurized by pumping the handle a designated number
of times. A control lever on the wand controls the spray pattern and amount.
Compression sprayers provide a precise, on target, non-drift spray good
for soil and lawn pests. Adjust the sprayer for a coarse, drenching spray,
a concentrated stream or a fine mist.
Tank capacities range from 1 quart to over 3 gallon for handheld models. Homeowner
type backpack sprayers hold up 4 gallons. The tanks may be made from polyethylene
plastic, galvanized steel or stainless steel.
In addition to treatments for pests and diseases, compression sprayers are designed
for applying cleaning solutions for decks and siding.
Backpack sprayers are operated in the same manner as the handheld compression
sprayer. The over-the-shoulder configuration makes it easier to carry
the heavier load of material. Some backpack models also use a lever-style
pump to maintain pressure without removing the unit form your back.
Powered sprayers rely on a gasoline engine for spray power. Great for larger
yards or gardens due to portability and capacity (12 gallons).
Dusters are a slightly different breed. Dry powders (mostly for blooming plants
such as roses) are added to a canister and applied by manually pumping.
NOTE:
Compression sprayers deliver liquid under pressure. Compression sprayers
are powerful and efficient tools. This fact also makes them potentially
dangerous. Always read the manufacturer's instructions and safety precautions
carefully.
With all sprayers, make sure the material is suitable for application with a sprayer.
A regular spraying schedule can help prevent many lawn and garden pest and disease problems.
| Early Spring |
Dormant spraying:
Pests overwinter on shrubs, trees, and other woody plants. A dormant
spray stops many damaging insects and diseases before they have a
chance to develop. |
| Spring |
Lawn weeds:
Apply herbicide either when weed is actively growing or before it emerges, depending on the weed. Read the pesticide label for directions. |
| Early Summer |
Vegetable and flower gardens:
Check plants regularly for pest damage. Spray as needed.
Plant disease:
Remove all weeds and dead plants and begin a regular spraying program. Spray susceptible plants before there is evidence of damage. Repeat every 7-10 days.
Roses:
Check roses carefully for black spot on the upper surface of the leaf.
Remove and destroy infected leaves. Begin a regular spray program,
continuing until the first frost. |
| Summer |
Outdoor Areas:
Eliminate mosquito breeding places (standing water, weed patches,
etc.). Spray resting places (flowers, shrubs, dense foliage, outdoor walls & under leaves. |
| Late Summer |
|
Insects:
You may be troubled by two types of insects: The first lives in
the soil, damaging the grass roots, while the second attacks from
above the ground. You can correct insect problems with a spray program
and proper care of your lawn.
Weeds:
This time of year, many weeds are noticeable on your lawn, while
others are simply regrouping for the attack next spring. Both types
can be eliminated now with a spray program.
Lawn Disease:
Lawns that are shaded, watered at night, watered too frequently
or tend to remain wet for long periods are most likely to have disease
problems. A spray program will help stop the spread.

| Fall |
Foundation Spraying:
Spray the foundation around your house, especially in the fall. Crawling
insects are less likely to cross this pesticide barrier. Spray just
to the point of run-off and spray all the way around the house. Also,
spray a 2 - 4" inch band of soil alongside the foundation.

House Plants:
Insects: If you find signs of insect attack, you need to apply the proper spray material. |
