The Role Of Organic Pesticides In California

http://www.forbes.com/sites/stevensavage/2015/09/23/the-role-of-organic-pesticides-in-california/

"Did you know that organic farmers use pesticides? They do. Would it surprise you to know that many of the same pesticides are used by both conventional and organic farmers? In fact just over half of all the pesticides used in California by all categories of farmers are active ingredients that are approved for organic. Would it surprise you to know that very little of modern pesticide use involves highly toxic chemicals? In fact the organic-approved and synthetic pesticides used in California today have a similar distribution of relative toxicity , mostly at the low toxicity end of the spectrum. This sort of useful information is publicly available, and is helpful in addressing many common misperceptions about organic and about pesticides in general.

...

In the graph above I’ve broken out the 2013 California pesticide use by major categories based on pounds. The categories that have organic-approved active ingredients are indicated with the USDA logo and together these comprise 55% of the total pounds applied. These materials are extensively used by both organic and non-organic growers. The conventional growers have additional options, but definitely use some of these same materials as part of a resistance management strategy and for other practical reasons.

...

The reason that consumers can be confident that their food is safe is really the same for organic and conventional. The products that are allowed are rigorously evaluated, and the details of how they can be used are set through “label requirements” regarding worker safety, restrictions around sensitive habitats, rate and timing limits, and the time allowed between the last application and harvest. Those restrictions (which exist for both organic and synthetic pesticides) are designed to ensure that any residues at the consumer level are well below a very conservative threshold called a “tolerance” in the US and MRL (maximum residue level) in other countries. In the US and Canada respectively the USDA and Health Canada take random samples of foods from the commercial supply and test them in labs for the presence of pesticide residues. What they find is very encouraging and should give consumers considerable confidence (this independently developed website allows you to visualize this public data source). Interestingly, this testing does not include a look at the highest use-rate organic-approved pesticides (sulfur, petroleum derived oils, copper compounds). To do so would require an additional testing regime at considerable cost, and the materials are not considered to be of sufficient concern to warrant that.

So in conclusion, pesticides are definitely used on organic crops. Organic and conventional growers use many of the same chemicals. For the organic and synthetic pesticides in use today there is a similar distribution of intrinsic acute, oral toxicity. Consumer confidence in this area can be based on highly transparent sources of data and on the legacy of decades of environmental campaigning, decades of increasingly rigorous regulation, and billions of dollars of investment in finding better and better options for pest control."



The graphs are very interesting, when they are compared to one another.
