FOR SMALL VOLUME PESTICIDE APPLICATIONS MO FOLIAGE PLANTS. 4o

ARC-Apopka Research Report PV-1973-4


Introduction:

Recommendations on the use of pesticides are given normally as the

quantity needed per 100 gallons water. For the grower desiring to prepare

these chemicals in small quantities, however, an easy and reproducible

method of measuring the pesticide is needed. This report contains a

simple and efficient method for the measurement of small volumes of some

fungicides and insecticides that are commonly used in the Florida foliage

industry.

The suggested quantities given in this report are on a one gallon

basis. The final concentrations upon which the simple measurements are

based, are those that have been found to be generally safe to foliage

plants and effective in disease or insect control. To determine which

pesticide to employ in any particular situation, the reader is advised to

consult the articles listed at the end of this report for information on

specific diseases and insect problems.


The Method

To accurately and safely measure small pesticide quantities the

following items are needed: a set of aluminum measuring spoons, a wooden

pot label, a Wilson 'Agri-Tox" type respirator, plastic safety goggles, a

pair of Playtex-type rubber gloves and a light plastic apron. The first

two items are needed to properly measure the pesticide, and the last four

should be worn to eliminate any internal or external pesticide contamination

of the person measuring the pesticide.

If the pesticide is a wettable powder, the quantity needed is obtained

as follows:

1. Dip the necessary-sized spoon into the open pesticide container

and carefully extract an abundant quantity while holding the

spoon over the opened container.

2. Take a clean wooden label and press the pesticide into the

concave cavity of the spoon.

3. With the broad flat surface of the wooden label using a back

and forth motion, level the pesticide to be even with the top

of the spoon. The excess pesticide will fall back into the

opened container.

4. Put the required amount of pesticide into the spray or drench

tank. Before addition of the pesticide, the tank should already

contain approximately one half of the total volume of water

required. Wash off the pesticide adhering to the spoon and wooden

label into the tank with the water used to bring the mixture to

the total volume required.

5. After proper agitation or mixing, this small volume should be

very close in concentration to large tank mixtures.

Note: When measuring an emulsifiable concentrate, it is

recommended that the pesticide be poured very carefully into the

spoon which is held over the partially filled spray or drench

tank. If the pesticide container is too large to handle, pour

a portion of the pesticide into a smaller container from which

pouring into the measuring spoons can be accomplished more easily.

Again, the pesticide should be washed off the measuring spoon

into the tank. Emulsifiable concentrate measurement requires

a person with a steady hand to eliminate too high a concentration

which can easily result from spills occurring during pouring.


Use Caution

Do not be careless and measure the pesticides without the proper

safety equipment. *Do not take short cuts and by-pass the proper measuring

technique stated. The measurements needed to produce desired concentrations

of pesticide solution are based on tests run at the Agricultural Research

Center Apopka and they will give you the needed concentration only if

you take the time to measure the pesticide properly. Remember, improper

measurement may result in either poor pest control (too little measured)

or plant injury (too much measured).

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.

Follow the rules which are listed in the supporting publications on

when and how to apply the pesticides. If you do not already have some or

all of these publications, they may be obtained by writing to the "Extension

Specialist, Agricultural Research Center Apopka, Rt. 1 Box 980, Apopka,

Florida 32703". Do not forget to include your Zip Code.
