Cogongrass is a weed throughout the tropics and subtropics. Introductions early this century have spread into forests, rangelands, reclaimed mined areas, roadsides, and natural ecosystems in the southeastern United States. Vegetative reproduction is the primary mechanism for survival and local spread, and sexually produced seeds of this obligate outcrossing species provide natural long-distance dispersal. Highly germinable (≥ 90%) seeds have no dormancy, though spikelet fill may be low (≤ 40… 

Cogongrass (Imperata cylindrica)—Biology, Ecology, and Management

Cogongrass is a major impediment to reforestation efforts in southeast Asia, the number one weed in agronomic and vegetable production in many parts of Africa, and is responsible for thousands of hectares of lost native habitat in the southeastern U.S.

Use of Glyphosate and Imazapyr for Cogongrass (Imperata cylindrica) Management in Southern Pine Forests

G glyphosate, imazapyr, and the combination of these herbicides as the most effective herbicides for controlling cogongrass are identified in Florida and Asia.

Pushing toward Cogongrass (Imperata cylindrica) Patch Eradication: The Influence of Herbicide Treatment and Application Timing on Cogongrass Rhizome Elimination

It is demonstrated, for the first time, that the entire rhizome layer of cogongrass can be eliminated within 3 yr with multiple treatment options and that cogonrass patch eradication is possible for many land managers.

Impacts of Prescribed Fire, Glyphosate, and Seeding on Cogongrass, Species Richness, and Species Diversity in Longleaf Pine

Glyphosate treatment following prescribed burning provided a minor but significant increase in cogongrass control compared to glyphosate-treated, unburned plots, but the effect was short-lived and not useful when follow-up glyphosate treatments were applied.

Simulation of shoot emergence pattern of cogongrass (Imperata cylindrica) in the humid tropics

This is the first model developed for cogongrass shoot emergence based on hydrothermal time under field observations that predicted shoot emergence satisfactorily in six treatments that simulated farmers' practices in southwestern Nigeria.

EVALUATION OF GROWTH REGULATING HERBICIDES FOR IMPROVED MANAGEMENT OF COGONGRASS AND TORPEDOGRASS

It is hypothesized that disruption of normal auxin levels in torpedograss and cogongrass would encourage new secondary shoot production, and sought to achieve abnormal auxin Levels using plant growth regulating (PGR) herbicides and follow this with different rates and application timings of glyphosate or imazapyr to improve efficacy.

Ecotype Variability and Edaphic Characteristics for Cogongrass (Imperata cylindrica) Populations in Mississippi

These data indicate that cogongrass is able to establish, emerge, grow, and reproduce on a wide array of soils in Mississippi, giving it an advantage over other plant species that are more limited in the soil types that support their growth.

Cogongrass (Imperata cylindrica) : Biology, Distribution and Impacts in the Southeastern U.S

Biology Cogongrass is a warm-season perennial grass species found throughout the tropical and subtropical regions of the world (Holm et al., 1977). It produces extensive rhizomes which allow it to

Tolerance of Several Legumes to Residual Imazapyr Applied Under Greenhouse Conditions

Abstract Control of noxious weeds such as cogongrass depend heavily on chemical treatment, but success is limited unless integrated with other practices. Utilization of cover crops in the system is

Cogongrass, Imperata cylindrica, in the United States

Cogongrass is an aggressive, pernicious, rhizomatous perennial in the Poaceae (Graminae) that infests 200 million ha in Asia, several thousand ha in the Southeastern United States, and over 500 million ha worldwide.

Factors Limiting the Distribution of Cogongrass, Imperata cylindrica, and Torpedograss, Panicum repens

It is postulated that cogongrass spread is limited by lack of axillary bud formation on most of the rhizome and the inability of rhizomes to send up new shoots if buried deeper than 8 cm, which could account for the intolerance of cogongRass to cultivation.
