well. Don'tirrigate immediately after a pesticide
application, unless required by a pesticide's label.
The increased water content in the soil might speed
up the downward movement of a pesticide.

Remember that you must protect your groundwater.

[!]Care and maintenance of your equipment is
also an important consideration. If your equipment
does not function properly, you may be applying
more than is needed and increasing the chance of
groundwater contamination. Prior to the beginning of
the season, inspect all of the working parts of your
sprayer or chemigation system. Check the pump to
see if it is working properly. For both sprayers and
chemigation systems, check the water lines for clogs
and leaks. For sprayers, check the nozzles for wear
and clogs. Clogged, leaking or worn lines and
nozzles can cause pesticides to be delivered in too
high an amount or in unwanted areas. Be sure to
calibrate your equipment. Uncalibrated equipment can
cause over delivery as well. You should calibrate
your equipment at the beginning of the season,
periodically during the remainder of the season and
any time you make changes or adjustment to the
equipment.

[!]Apply materials only when needed. The use of
pesticides, when not needed can increase the threat of
contamination. Check your irrigation practices as
