Advantages:
•
inexpensive
•
convenient
field access unnecessary.
Disadvantages:
•
•
constant agitation needed in slurry tank
•
application of more water per acre than recommended on label
will result in leaching the chemical from the effective soil zone.
•
sprinkler distribution must have appropriate overlap pattern to
avoid underdosing or overdosing.
•
injection of pesticides into flood and furrow irrigation systems
may result in uneven concentrations of pesticides throughout the
field, depending on soil permeability and field contours.
C. WAX BARS
Herbicides are sometimes applied to turfgrass and vineyards with wax
bars. The wax bars are impregnated with herbicides, then dragged slowly over
the area to be protected.
Advantages:
•
no drift
no calibration.
Disadvantages:
•
•
highly specialized, not readily available.
VIII. CONCLUSION
Many factors affect the ability to place a pesticide on the target in the
manner and amount for most effective results, with the least undesirable side
effects, and at the lowest possible cost. Certainly the selection and use of
equipment are of utmost importance and deserve major emphasis when consid-
ering pesticide application. However, without proper consideration to calibra-
tion, formulation, adjuvants, compatibility, and use records, successful appli-
