Bayer Chemistry to Develop New Herbicides

Chemistry: Weeds are becoming resistant to selective herbicides.
Herbicides have officially been used since 1890, though common salt could have used to kill weeds for possibly a thousand years before. The first selective herbicide was identified in 1940. It later became 2,4-D compound and was released in 1946.  Seventy years later we face the problem of weed resistance to selective chemicals. Western Australia can no longer get significant kill of weeds growing around crops. It is costing farmers a fortune.
Ryegrass weed growing in crops
Project Kangaroo has been initiated. It is managed by Australia’s Grains Research and Development Corporation (GRDC) and receives assistance from Bayer of Germany. Money from growers is funding it: they are paying $45 million in levies. The Federal Government is promising money. Knowing how government has behaved recently the project might get a dollar!

Wild radish and ryegrass are the main culprits affecting crops. Glyphosphate was used widely to control these weeds. They are not very effective these days. Chemical companies need to take a new tack and work at the molecular, even atomic level, to find ways of killing selective weeds. Nature though is good at overcoming new things in the environment. It is only a matter of time before evolution beats "unique" obstacles set up by Man.

Don't Get Excited About Nuclear Power

The world is in a tight corner and people are far too optimistic. Thinking that carbon pollution will cure itself is not scientific fact. Only a fool would hang onto the notion that nothing is wrong. The poles are thawing out and that is fact. Polar bears are dwindling in number as their traditional frozen feeding grounds get warmer. Butterflies that used to stay on in winter in southern England have moved north to colder climes. Those species that stay are getting larger.

Despite coal power stations being the main culprit more are being built to meet Mankind's increasing demand. Much is said about nuclear power stations holding the key to a "clean" future. Used uranium is going around Europe at this very moment without finding a home in any country. Where will this dangerous product be put in the future? Unless it is blasted into space toward the sun there is no where for it to go. France gets more than 80 percent of its electric power from nuclear means, but this is the country with the used uranium problem.

Even some scientists say the carbon footprint of nuclear power will be reduced to zero. This is hogwash. If you ignore nuclear waste everything looks good. Include it and it all looks very bad indeed. Nuclear power isn't cheap. Building a nuclear power plant requires long term planning. Safe guards are costly. Their useful life is also limited. Coal plants can stay in operation for much longer.

Within twenty years all 25 of China's new nuclear plants will come online. The world will be a militants' paradise with used uranium for sale on the open market. The consequences will be catastrophic. Saying there is no carbon price is absolute rubbish. If a bomb goes off there will be plenty of pollution.
