Pesticide recommendations are common mw44 .irt-i gai ii unds or
ounces) needed per 100 gallons of water. Mangrowers--use-sma l'. volumes of
water, even as little as 1 gallon amounts. A simple and efficient method for
measurement of small amounts of some pesticides registered for use on foliage
plants has been described previously and is included below.

To accurately and safely measure pesticides in small quantities, the
following items are needed: a set of aluminum measuring spoons, a pot label or
other tool used to level, a chemical cartridge respirator approved for use
with pesticides, plastic safety goggles, a pair of heavy rubber gloves and a
light plastic apron. The first two items are needed to properly measure
pesticides and the last four should be worn for safe handling of the pesticide.

If the pesticide is a wettable powder, the quantity needed can be obtained
as follows. Dip the measuring spoon into the open pesticide container and
carefully extract an abundant quantity while holding the spoon over the opened
container. With the broad flat surface of the wooden label, level the pesti-
cide even with the top of the spoon. The excess pesticide should fall back
* into the opened container. Put the required amount of pesticide into the spray
or drench tank, already containing approximately one-half the total volume of
water required. Wash off any pesticide adhering to the spoon and label into
the tank with the remaining water and bring the mixture to the total volume
required. After proper agitation or mixing, this small volume should be very
close in concentration to large tank mixtures.

When measuring emulsifiable concentrates or flowables, the pesticide
should be poured carefully into the spoon held over a partially filled
container. If the pesticide container is too large to handle, pour a portion
of the pesticide into a smaller container to facilitate pouring into the
measuring spoon. Again, the pesticide should be washed off the measuring spoon
into the container, and the volume brought up to the appropriate level by pour-
ing into the spray tank and rinsing with water. Liquid pesticide measurement
requires a person with a steady hand to eliminate too high a concentration
which can easily result from spills during pouring.

Do not measure pesticides without proper safety equipment. Do not take
short cuts and by-pass the proper measuring technique. The measurements
needed to produce desired concentrations of pesticide solution were determined
at the Agricultural Research and Education Center, Apopka, and they will give

you the desired concentration only if you measure the pesticide properly.
Remember, improper measurement can result in either poor pest control (too
little measured) or plant injury (too much measured). Note that a given rate
of one 75WP is not equivalent to the same rate of a different 75WP when
measured in teaspoons.

After measuring the needed portion of pesticide, all pesticide containers
should be immediately locked in a suitable pesticide room and any spilled
pesticide cleaned up and disposed of. The quantities given in this report are
for either a 100 gallon or 1 gallon volume of water. The concentrations upon
which measurements are based are those given on pesticide labels and should be
followed at all times. All labels should be read carefully prior to using a
pesticide, particularly if the pesticide has not been used previously. For
additional information on pesticide use on foliage plants consult the articles
listed below.
