cattail are invasive aquatic plant life that thrive on the edges of streams , ponds and swamp . The herbicides used to belt down them commonly require a wetter register for use on aquatic plant . A surfactant is an federal agent that allows the herbicide to spread more equally on water and not form beads . Herbicides containing glyphosate are most often recommended to kill cattail . Always trace the counsel on the producer ’s recording label .

Glyphosate

Herbicides containing glyphosate are blanket spectrum and systemic . They are absorbed by the plant and act more tardily than contact herbicides . A systemic herbicide kills the roots and the rest of the plant . Glyphosate herbicides are more expensive than those that kill on contact , but they ’re more useful to eliminate a perennial stand . cattail can be sprayed by walk along the shore . It is n’t necessary to spray from several Angle as you would with a touch weed killer . give glyphosate weed killer just after the seed head has formed . This is when cattails begin to store food in their ascendent .

Diquat

Diquat is the tight - represent chemical ingredient in commercial-grade herbicide that kills on contact . Since diquat kill only the portion of the industrial plant it allude , it ’s necessary to cover an intact cattail works to eliminate it . That means cattail must be spray from several direction . Diquat weedkiller do not kill the root organisation . Since new plants can grow from these roots , using a diquat herbicide requires yearly covering . use diquat when the cattail are green and actively growing . There may be state jurisprudence governing the usance of diquat in your orbit . see with your local agricultural extension service or state section of agriculture to chance jurisprudence that may apply .

Imazapyr

Imazapyr conquer a essential plant enzyme in cattails . Herbicides containing glyphosate and imazapyr bind to particles set aside in the water and on the bottom where they rapidly become inactive . There is no look period for irrigation or using the water for stock .

Imazamox

Plant - kill expression containing imazamox are broad spectrum and systemic . One danger of using imazamox and other herbicides to operate cattail in a pool is that rot dead plant can deplete oxygen in the water , down fish . If a pool is to a great extent infested with cattails , it may be near to shoot down them in section and let each discussion section rot for two weeks before treating another surgical incision .
