Backflow Prevention in Chemigation of
Pesticides
Steven G. Liescheidt, P.E., CSI-CCS, CCPR.
Overview
Chemigation, or the addition of chemicals to
irrigation water, has probably been around for as long as both irrigation and
chemicals have been used in agriculture. Chemigation became more widely used in
the 1970’s with the adoption of center pivot irrigation systems in the Midwest.
Backflow prevention is necessary to prevent pesticide contamination of surface
water supplies as well as ground water.
In this course the student will learn about
pesticide label requirements for Chemigation, Chemigation system operation and
calibration and Chemigation system safety.
The student is expected to read and review the material contained
in Grower Training Manual for Backflow Prevention in Chemigation of Pesticides,
Revised 3/3/04.
The student must take a
multiple-choice quiz consisting of ten (10) questions at the end of
this course to obtain PDH credits.
