Helena Chemical Co. will market and sell Enzone Soil Fumigant nationwide under a recent licensing agreement with Entek Corp.

Enzone is a water-soluble fumigant that is used as a management tool to control phylloxera, nematodes and various fungal diseases in select cropping systems. Because of its control spectrum, it can replace methyl bromide in certain cropping systems.

Enzone is currently registered for use in Arizona, California, Oregon and Washington, with registration pending in several other states.

Enzone should not be used in greenhouses or other enclosed areas.
