wild B. campestris. <strong>The</strong> results of the Danish team<br />

showed that high levels of hybridization can occur<br />

in the field. <strong>The</strong>ir field tests revealed that between<br />

nine percent and 93 percent of hybrid seeds were<br />

produced under different conditions. (Jorgensen,<br />

R.B and Anderson, B., (1994), “Spontaneous<br />

Hybridization between oilseed rape (Brassica<br />

Napus) and weedy B.Campestriz (Brassicaceae): A<br />

risk of growing genetically modified oilseed rape”,<br />

American Journal of Botany).<br />

<strong>The</strong> scientists also warn that as the gene for<br />

herbicide resistance is likely to be transferred to the<br />

weed, this herbicide strategy will be useless after a<br />

few years. Like many other weeds, B. campestris is<br />

characterized by seed dormancy and longevity of<br />

the seeds. <strong>The</strong>refore, B. campestris with transgenes<br />

from oilseed rape may be preserved for many years<br />

in spite of efforts to exterminate it. <strong>The</strong>y conclude<br />

that weedy B. campestris with this herbicide<br />

tolerant transgene may present eco<strong>no</strong>mic risks to<br />

farmers and the biotech<strong>no</strong>logy industry. Finally,<br />

natural ecosystems may also be affected.<br />

Other concerned scientists add that the potential<br />

spread of the transgene will indeed be wide<br />

because oilseed rape is insect-pollinated and bees<br />

are k<strong>no</strong>wn to fly far distances. <strong>The</strong> existence of the<br />

wild relative of B. campestris in large parts of the<br />

world poses serious hazards once the transgenic<br />

oilseed rape is marketed commercially. In response<br />

to the Danish findings, the governments of<br />

Denmark and Norway have acted against the<br />

commercial planting of the engineered plant, but<br />

the U.K Government <strong>has</strong> approved its marketing.<br />

Wild beets have become a major problem in<br />

European sugar beet production since the 1970s.<br />

<strong>The</strong>se weedy populations arise from seeds<br />

originating from the accidental pollinations of<br />

cultivated beets by adventitious beets in the seed<br />

production area. <strong>The</strong> existence of gene exchange<br />

via seed and pollen between weed beets and<br />

cultivated beets shows genetically engineered<br />

sugar beets to be herbicide resistant, with the<br />

possibility of becoming “super-weeds.” In this<br />

case, the efficacy of herbicide resistant crops<br />

totally undermined. (P. Bondry, M. Morchen, P.<br />

Sanmiton-Laprade, Ph. Veernat, H.Van Dyk, “<strong>The</strong><br />

origin and evolution of weed beets: Consequences<br />

for the breeding and release of herbicide resistant<br />

transgenic sugar beets: <strong>The</strong>or-Appl Genet (1993),<br />

87:471-78).<br />

Current surveys indicate that almost 20 percent<br />

of U.S producers have found glyphosate resistant<br />

(Roundup Resistant) weeds on their farms. (http://<br />

Referring to Round Up Resistant weeds,<br />

Andrew Wargo III, the President of the Arkansas<br />

Association of Conservation Districts said, “It is<br />

the single largest threat to production agriculture<br />

that we have ever seen”. (William Neuman &<br />

Andrew Pollack, Farmers Cope with Round-Up<br />

Resistance Weeds, New York Times, 4th May<br />

2010).<br />

<strong>The</strong>re are <strong>no</strong>w ten resistant species in at least 22<br />

states infesting millions of acres, predominantly<br />

soybeans, cotton, and corn. Roundup Resistant<br />

weeds include pig weed, rag weed, and horse<br />

weed.<br />

Today, Roundup Ready crops account for 90<br />

percent of soybeans and 70 percent of corn and<br />

cotton grown in the US.<br />

Mike Owen, a Weed Scientist at Iowa State<br />

University <strong>has</strong> cautioned: “What we’re talking<br />

about here is Darwinian evolution in fastforward.”<br />

As a result of this weed resistance, farmers are<br />

being forced to use more herbicides to combat<br />

weeds. As Bill Freese of the Center for Food Safety<br />

in Washington, D.C., says “<strong>The</strong> biotech industry<br />

is taking us into a more pesticide dependent<br />

agriculture, and we need to be going in the<br />

opposite direction.”<br />

<strong>The</strong> problem of “superweeds” is so severe that<br />

U.S Congress organized a hearing on it titled “Are<br />

Superweeds on Outgrowth of USDA Biotech<br />

Policy”.<br />

(http://westernfarmpress.com/management/super-weedsput-usda-hotseat)<br />

Superweeds infest a GM corn field<br />

As Roy Troush, an Indiana farmer, stated in his<br />

testimony: “In 2005 we first began to encounter<br />

problems with glyphosate-resistance in both our<br />

soybean and corn crops. Despite well documented<br />

proof that glyphosate tolerant weeds were<br />

becoming a significant problem, the Monsanto<br />
