From food products to cosmetics, medicines to insecticides, the product offering so-called natural expanded, well supported by a dynamic marketing and opportunistic. Naturopathy, homeopathy, aromatherapy and organic products have the wind in their sails, and benefit greatly from this new passion.
The “natural” trend is. His apostles zealous very present in the media does not prove to as much of their knowledge of the reality of nature.This appeal of the natural is becoming for some a way of life that marginal is wanting to be close to a nature worshipped. This choice of “natural” is naive and often poorly reasoned.
The pesticides, despite the stringent controls imposed on pre-market and the progress of manufacturers and farmers, elicit a rejection without shades.
Thus, the glyphosate, the active ingredient in the herbicide Roundup®, is the subject of numerous smear campaigns in view of their prohibition in a real denial of the services rendered to agriculture and to its good toxicological profile recognized for the past 40 years. Why ? Because a study* among hundreds of others proving the safety of this herbicide, has unwisely been classified as a “probable carcinogen”… as in red meat !
A lot of natural pesticides (substances synthesized by plants to defend themselves against their perpetrators) are often toxic to humans and commonly consumed. Who is talking about it ? Why escape to regulatory controls ?
The government encourages methods of crop protection alternatives to pesticides, such as biological agriculture (AB) authorizing the use of pesticides that are deemed more natural. Are they ? The case of the copper sulphate, a chemical compound that accumulates in the soil ? Or plant extracts such as pyrethrum, neuro-toxic ? Or neem oil in which the major component, azadirachtin, is an endocrine disruptor ?
If it is agreed that organic foods contain fewer chemical residues, they are more exposed to biological contaminants in “natural” hazardous, such as mycotoxins, salmonella, or bacteria, including a mutant strain and pathogenic Escherichia coli is the cause of many sick, and nearly 50 deaths in 2011 in Germany.
However, the AB has an amazing way of derogation : it is subject to an obligation of means but not of results !
The biocontrol using biological pest control using living organisms antagonists (insects, viruses, …) or chemical mediators (pheromones) is an alternative to chemical protection of plants. Method attractive but limited in its applications, it presents new risks to biological invasion of asian lady beetle introduced in France to combat the smart-rounds.
