<br />• Apply product only through sprinkler and dnp irrigation systems mcluding : center
<br />pivot, lateral move , end tow, side (wheel) roll, traveler, big gun. solid se~ or hand
<br />move; flood (basin). ftlrrow, border or drip systems
<br />· Crop injury. lack of effectiveness, or illegal pesticide 1esidues in the crop can result
<br />from non-uniform distribution of treated water,
<br />• II you have questions about calibration, contact Applied Biochemists State Ex ten
<br />sion Service, equipment manufacturer, or other experts .
<br />• Do not connect an irrigation system (including greenhouse systems) used for pes-
<br />ticide application to a pub li c water system unless the pesticide label-prescribed
<br />safety devices for pub lic water systems are 1n place (refe r to !he Chernigation
<br />Systems Connected to a Public Water Supply section of this label).
<br />Trained personnel, knowledgeable of the Chemigatlon system and responsible f01
<br />its operation or under the superv ision of the responsible person , shall shut the
<br />system down and make necessary adjustments should the need arise. The system
<br />shou ld be mspected. cal ibrated. and maintained before product application begins
<br />Chemigation Systems Connected to a Public Water Supply
<br />• Public water system is a system for the provision to the public of piped water for
<br />human consumption 1f such systerr1 has at least 15 service connections or regularly
<br />serves an average of at least 25 individuals daily at feast 60 days out of the year.
<br />• Chemigation systems connected to public water systen1s must contain a functional .
<br />reduced-pressure zone, back flow preventer (RPZ) or the functional equivalent in
<br />the water SL1pply line upstream from the point of pesticide introduction There shall
<br />be a complete physical break (air gap) between the flow outlet end of the fill pipe
<br />and the top or overflow rim of the reservoir tank of at least twice the inside diameter
<br />of the fill pipe .
<br />• The pestfcide Injection pipeline must wntain a functional, automatic. qurck-closfng
<br />check va lve to prevent the backflow of solution toward the injection .
<br />·The pesticide injection pipeline must contain a functional, normally closed , solenoid
<br />operated valve located on the intake side oi ihe injec ti on pump and connected to
<br />the syster11 interlock to prevent fluid from being withdrawn from the supply tank
<br />when the irrigation system is eithe1 automatically or manua ll y shut down.
<br />• The system must contain functional interlocking controls to automatically shut off
<br />the pes ticide injection pump when the water pump motor stops or in cases where
<br />there is no water pump , when the water pressure decreases to the point where
<br />pesticide distribution Is adversely affected.
<br />• Systems must use a metering pump, such as a pos itive displa cement Inject ion
<br />pump (e .g.,diaphragm pump) effectively designed and constructed of matenals
<br />that are compatible with pesticides in use and capab le of be ing fitted wi th a system
<br />in terlock .
<br />• Inspect, calib1ate and maintain the system before product applica ll on.
<br />Sprinkler Chem igatfon Requirements
<br />• Th e system must contain a functiona l check valve vacuum relief valve, and low
<br />pressure drain appropriately located on the irrigation pipeline to prevent water
<br />source contaminat ion fron1 back flow.
<br />• The pesticide injection pipe line must contain a functional, automatic, qui ck -closing
<br />check valve to prevent the back11ow of solution toward th e injection pump.
<br />• The pesticide injection pipeline must also contain a functional, normally closed,
<br />solenoid operated valve locale<! on the intake side of the injection pump and con-
<br />nected to the system intertoc l< to prevent fluid from being withdrawn from the sup-
<br />ply tank when the il rigation system is either automatically or manually shu t down
<br />• Th e system must contain functional interlock ing controls to automatically shut off
<br />the pesticide injection pump when the water pump motor stops
<br />• Th e irrigation line or water pump must Include a functiona l pressu re switch which
<br />wllt stop the water pump motor when the water pressure decreases to the point
<br />where pesticide distribution is adverse ly affec ted .
<br />• Systems must use a metering pump . such as a positive displacement inj ection
<br />pump (e.g diaph ragm pump) effectively designed and constructed of materia ls that
<br />are compaliiJie wiUl pesticides and capab le of being fitted with a system interlock.
