The Difference Between Eraser and Eraser Max

Eraser Weed & Grass Killer Concentrate contains the active ingredient glyphosate.  It is a non-selective, broad-spectrum product – it will kill virtually any growing plant that you spray it on.  (See the product label for a list of all plants controlled.)  When Eraser is applied to actively growing plants, it’s taken up by the foliage and moves to the roots and growing points, stopping growth and killing the plant.  Eraser works slowly; it can take up to 2 weeks for plants to be completely killed. 

Eraser has no activity in soil; it must be applied to the foliage of actively growing plants to be effective.  The lack of soil activity also means that Eraser has no residual activity, and it will not affect nearby untreated plants.  Treated areas may be replanted 1 – 3 days after application of Eraser (see label for details).

Eraser Max Super Concentrate Herbicide contains glyphosate, as well as another active ingredient, imazapyr.  This makes Eraser Max a very different product in several important ways:

• Imazapyr is active in soil where it is taken up by plant roots.
• It can move through the soil into parts of the landscape where it wasn’t sprayed, damaging plants there.
• It is a long-lasting product, with residual activity lasting up to one year.

Because of this, there are some important precautions to follow when applying Eraser Max:

• Only apply to areas where no vegetation is desired for one year.
• Do not apply over the roots systems or desirable plants. For trees and shrubs do not apply closer than twice the distance from the trunk to the drip line as roots may be within this area.
• Do not apply to slopes in landscape as movement on soil surfaces may damage desirable plants down slope.
• Do not apply next to a fence if desirable vegetation is growing on the other side, or if future planting is intended.
• Do not use before planting lawns, fruits, vegetables, flowers, or other plants because this product remains active in soil for up to one year.

Eraser Max is ideal for fence rows, gravel paths, sidewalks, driveways, parking areas and around farm buildings and barns - places you don't want anything to grow. One application kills weeds for up to one year.
