The extensive root system of the semi-dormant grass cicero makes permanent removal of infested fields difficult. However, a relatively new herbicide has been tested for this relatively specific invasive weed grass. Halosulfuron-methyl Nutgrass effectively control purple, if there are no new shoots are used regularly. It seems to work on a Nutgrass yellow.
Nutgrass purple or yellow is often taken for granted fast-growing grasses appear a day or twoafter a lawn is shaven. His 3-5 green shoots per plant have a strong vertical line down their centers. Because of its non-invasive widespread always-connected root system, there Nutgrass tumors according to the current ones above ground were destroyed. For this reason, the herbicide treatments are ineffective unless frequently, until all their root systems have been destroyed completely done.
The results of a comparative study.
A study by aSouthwestern University halosulfuron showed the same root-methyl-killing power is the herbicide glyphosate how to kill all vegetation. However, methyl-halosulfuron two advantages over the kill-all herbicide.
1 Not bad most other lawn grasses.
Halosulfuron-methyl does not damage the lawn grasses such as fescue traditional, bluegrass and ryegrass. There is some burmudas yellow. However, it is safe to use on warm season grasses or cooland close to established ornamentals, shrubs and trees. However, it should not be applied to plants or vegetable bed.
2 It 'easy to see the place to apply spray.
For the reasons above, this is diluted with water chemistry can be easily applied to the growth as Nutgrass spray-treatment of a small hand to the gallon, not simply meet, as on the surrounding grass lawn.
Since the syringestree branches with applications to spray the herbicide can be disproportionately expensive these are only individual or small groups of shoots done. If tree branches are strong with Cicero, a homeowner may be a lawn care professional to treat the entire courtyard with its own chemical mass less expensive first. Another possibility is killing the entire lawn, and then seeding it again from scratch. Otherwise, it could take several litersthis solution herbicide for the job.
How halosulfuron Nutgrass use of methyl-moderate infestation.
Written instructions and precautions with this product that is sold under the brand names, such as, MON-1200, management and Sedgehammer Haolsulfuron Pro-come, easy and very easy to read. Currently, a form of the product is presented as a solid of 0.9 grams water-soluble package ($ 15), diluted in a gallon ofWater together with a small amount of surfactant leaves sticker ($ 5), if desired. One or two drops of dish soap might work as well. Then just spray on the ground Nutgrass shoots up to its instincts or leaves are covered (wet and shiny).
The yellow Nutgrass start to 4-7 days. He will die in about two weeks. After this, freshly prepared solutions may be sprayed on any new shoots until they and their root systems were removed.
