New Mancozeb scientific review - Parkinson disease

A recent blackspot thread included one recommendation to use Mancozeb.

H.Kuska comment. What does recent science have to say about it's safety.

Please look at a the full copy of a very recent (2013) scientific review of prior published studies concerning Parkinson disease.

"Exposure to paraquat or maneb/mancozeb was associated with about a 2-fold increase in risk."

H. Kuska comment. My recommendation is that there is enough information to warrant recommending the utilization of the Precautionary Principle.

HAHAHA -- I wouldn't touch that stuff with a ten-foot pole. How badly could you POSSIBLY want perfect foliage?

OMG Henry. How low can you go?

Did you read the conclusions?
"Further prospective and high-quality case-control studies are required to substantiate
a cause-effect relationship. The studies should also focus on specific chemical agents."

This is nothing more than a reach for a $$grant. Might as well have been for cell phone micro waves.

"precautionary principle World English Dictionary
precautionary principle
��" n
the precept that an action should not be taken if the consequences are uncertain and potentially dangerous"

The following link gives more detail:

In particular the following part should help clarify:

"What about "scientific uncertainty"? Why should we take action before science tells us what is harmful or what is causing harm?
Sometimes if we wait for proof it is too late. Scientific standards for demonstrating cause and effect are very high. For example, smoking was strongly suspected of causing lung cancer long before the link was demonstrated conclusively - that is, to the satisfaction of scientific standards of cause and effect. By then, many smokers had died of lung cancer. But many other people had already quit smoking because of the growing evidence that smoking was linked to lung cancer. These people were wisely exercising precaution despite some scientific uncertainty.

Often a problem - such as a cluster of cancer cases or global warming - is too large, its causes too diverse, or the effects too long term to be sorted out with scientific experiments that would prove cause and effect. It's hard to take these problems into the laboratory. Instead, we have to rely on observations, case studies or predictions based on current knowledge.

According to the precautionary principle, when substantial scientific evidence of any kind gives us good reason to believe that an activity, technology or substance may be harmful, we should act to prevent harm. If we always wait for scientific certainty, people may suffer and die, and damage to the natural world may be irreversible."
