Note:
For operational reasons, a Magnacide application may be cancelled or rescheduled. For rescheduled applications, affected waterusers will receive notification from their ditchrider.
During the application no water is permitted to enter municipal waterworks systems, water systems used to supply water for household purposes, dugouts or ponds used for livestock watering, dugouts or ponds containing stocked fish. Please ensure that water you have diverted does not apply to any of these categories. We ask that you review our information package available from your ditchrider for more information about Magnacide H.
Organic growers irrigating should contact their ditchrider so they can be informed of any application which could affect organic crop certification.
