Cogongrass: 'weed from hell' spreading

 

 

“Cogongrass is so aggressive, if left unchecked it can replace an entire ecosystem,” says Jim Hancock, invasive plant control program coordinator for the Mississippi Forestry Commission at Brookhaven. It has been called “the weed from hell” and “the mother of all invasive species.”

 

I woke up this morning,

I looked out at my fields.

What I saw out there,

It made me want to squeal.

Them little white flowers,

They was growin’ everywhere.

It’s enough to make a man

Pull out all his hair.

I got the cogongrass blues.

What am I gonna do?

I got the cogongrass blues…

 

It may not make the Hit Parade, but “The Cogongrass Blues,” a ditty by The Blues Rangers band, mirrors the woes of landowners in Mississippi and other southern states who’ve seen their pastures, forest lands, and wildlife/recreational areas gobbled up by a weed that many liken to an invasion of aliens in a sci-fi movie.

And like the movie monsters, the grass just keeps spreading and spreading.

It has been called “the weed from hell” and “the mother of all invasive species.”

“It is so aggressive, if left unchecked it can replace an entire ecosystem,” says Jim Hancock, invasive plant control program coordinator for the Mississippi Forestry Commission at Brookhaven.

It is so solidly entrenched in many areas of Florida — with more than a million acres infested — that, he says, “It will still be there when Jesus returns.”

Like kudzu, another “foreigner” used for early era erosion control, the grass is spreading rapidly across the South — now as far west as eastern Texas and as far east as South Carolina.

In addition to Florida, heaviest infestations are now found across broad areas of southern Georgia, Alabama, and several counties of south Mississippi, and a multi-million dollar effort is now under way to try and curb its advance northward.

In 1979, only 19 counties in southern Mississippi had infestations; today it is in 50 counties across the state and continuing to spread.

Mississippi has just finished the first year of spraying in a $1.1 million suppression program, while Alabama has a $6 million-plus eradication program in progress.

“We’re running a lean, mean operation — everything we’re doing is geared to the spray program,” says Hancock, who briefed landowners on the weed and the control effort at a meeting at Starkville, Miss.

Cogongrass (Imperata cylindrica), thought to have originated in southeast Asia, is designated by many authorities as the seventh worst weed in the world. It is found in 73 countries on all continents.

From 1987~89, I was a US Peace Corps volunteer working as as Ag Extensionist in the Philippines. Cogon was a huge problem on my island of Mindoro. In Occidental Mindoro, the province in the western half of the island, a Japanese logging company had recently clear cut the provinces entire uplands and declared the bankruptcy of its Philippines subsidiary rather than replant the trees. The result was cogon investation of the entire uplands resulting in an actual change in the weather. The loss of the upland forests changed the weather from 7 months of rainy season/ 5 months of drought to 5.5 months rain/ 6.5 months drought. The cogon prevented the forset from slowly reestablishing itself without replanting.
Cogon has one excellent use, the high silica content makes it a premier material for thatched roofs, a thick one can last a century or more.
Cogon grass can be grazed, but must be kept super short, well less than knee high, under a foot is better. In the Philippines, cattle have been known to starve in tall lush green cogon because the silica content is so high that, even filling their bellies full, they can digest such a small portion of the cogon that they lose weight.
