Be Careful with Chemigation

48 picture

Chemigation requires particular care. Irrigation may carry pesticides downward through the soil into groundwater. Devices should be used to prevent possible backflow of pesticides into the water supply system. Materials used in pumps and seals should be compatible with the chemicals being injected. Check unattended systems frequently. Use only the amount of water needed to activate the pesticide.
