CITMIX


 I. INTRODUCTION


 Pesticide application is an important and expensive part of
the citrus grower's crop management program. Great care is taken
in selecting the specific pesticide to apply. However, the
actual mixing of the pesticide spray itself is often improperly
done. Many of the individuals who are responsible for
determining the proper amounts of pesticide, spray oil, and water
to be mixed make significant errors in their calculations. Some
are confused by the concept of "dilute spray" or by the
correction in the pesticide rate that is made when the pesticide
concentration exceeds AX. These concepts must be understood by
the pesticide applicator. Since they are adequately explained in
other publications, they will not be discussed in this manual. A
list of several of these publications can be found in Section
VIII "References."

 Improper spray mixtures contain either too much or too
little pesticide. Too much pesticide is illegal and
economically wasteful; too little pesticide will not provide
proper control of the target pest. In addition, too little
pesticide might require that a second or third spray be applied,
which would result in an even greater economic loss to the
grower. CITMIX provides a simple way to determine the correct
amount of pesticide to apply.
