In Florida alone, it has spread to more than a million acres. paillotte. It can be used to clear areas for planting and as part of an integrated approach to enable the establishment of legume ground covers (IRRI/ NRI, 1996; ICRAF, 1999).

It is considered to be an invasive species in 73 countries and one of the “Top 10 Worst Weeds in the World.” Cogongrass has several common names, including Japanese bloodgrass, Red Baron, or Speargrass. In this study, cogon grass was made as a material in paper making. Mississippi is under attack from one of the top 10 most invasive weeds in the world. Unfortunately, this weed continues to spread. For newer patches, tillage can eliminate cogongrass from an area if continued during the course of a growing season. Cogon grass paper-making requires soda ash to break down the fibers. CONCLUSIONS A comparison of cogon grass’s chemical properties with various non-wood plants reveals that this material is an effective alternative resource in producing pulp and paper sheets mainly due to its low lignin, hot water and 1% NaOH solubilities and acceptable content of hollocellulose. Contaminated firewood can spread tree-killing bugs. Cogongrass control varies according to the age and rhizome mat density and depth. Repeated applications each year for several years are needed for control. Even in the native countries, this plant becomes an invasive plant. Cogongrass prefers sandy soils with low nutrient levels, although it will inhabit more fertile sites. Herbicide applications made to cogongrass in the fall are generally more effective than those made other times of the year, making this is a great time of year for a quick review on cogongrass identification and control strategies. <>/ProcSet[/PDF/Text/ImageB/ImageC/ImageI] >>/MediaBox[ 0 0 595.32 841.92] /Contents 4 0 R/Group<>/Tabs/S/StructParents 0>>

Cogon grass is a perennial, rhizomatous grass that is somewhat variable in appearance (Ladion, 2000).

Applications of Arsenal, Imazapyr, Polaris, or Habitat (2 pounds imazapyr per gallon formulation) at 48 ounces per acre can be used in certain areas and provide excellent control up to 1 year after application. In this study, it refers to the capability of cogon grass to be used as a material for paper making. Cogongrass (Imperata cylindrica) is an invasive, non-native grass that occurs in the Southeast region of the United States. Seedlings begin to produce rhizomes about 4 weeks after emergence. Since Arsenal remains in the soil for long periods, its effectiveness on cogongrass and other plants may continue up to a year after application. endobj
