Cogongrass [Imperata cylindrica (L.) Beauv.] was introduced into the Mobile Bay area of Alabama in 1911 or 1912. During the ensuing 60 years this rhizomatous weedy grass has spread into most of the southern portion of the state. Cogongrass has become a problem in agronomic and horticultural crops which are not intensively cultivated. Several currently available herbicides show promise of control. 

Control of Cogongrass by Herbicides

Experiments were conducted to develop controls for cogongrass [Imperata cylindrica (L.) Beauv.] on noncrop areas. Single and multiple applications of herbicides were evaluated in field tests. All

Comparative Morphological Development of Cogongrass (Imperata cylindrica) in Iraq

Field experiments were conducted to study the comparative morphological development of cogongrass ecotypes from 15 different locations throughout the three main regions of Iraq, finding distinct variations indicate the existence of different ecotypes of cogongsrass in Iraq.

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

Cogongrass [Imperata cylindrica (L.) Beauv.] Control using Chemical Treatment with Cover Cropping Systems

Field studies were conducted from 2014 through 2015 in Mississippi with the objective to determine the efficiency of utilizing a cover cropping system with glyphosate sequential applications for

Response of Twelve Florida Cogongrass (Imperata cylindrica) Populations to Herbicide Treatment

Findings indicate that variability in glyphosate efficacy, as suggested by managers, is unlikely due to any conferred resistance, and additional studies examining non-target impacts of aminocyclopyrachlor should be conducted to determine its potential fit into I. cylindrica management.

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.

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.

Biology and Control of Cogongrass (Imperata cylindrica) in Southern Forests1

Response of Selected and Random Plantings of Johnsongrass to Dalapon

Five strains of Johnsongrass in selected and random plantings received repeated foliar applications of 2,2-dichloropropionic acid (dalapon) and differed in their response to dalapon.

Control of Johnsongrass Ecotypes

Varying the rate of nitrogen fertilization had less effect on johnsongrass susceptibility to monosodium methanearsonate than to dalapon, and controlled sorghum almum (SorghumAlmnum Parodi) better than johnSongrass.

Cogon Grass in Mobile County, Alabama

The aggressive weediness of Cogon grass in cultivated fields and its limited value for forage were generally recognized by the farmers about Grand Bay and many were searching for an effective method of eradication.
