Kimbal, The report that I linked to confirm the information relationship is the same report that you used in your article. I should have made that clearer.

Glyphosate Use in Corn, 2009 & 2014

I’m not sure if there’s been another summary report done, but I looked up the numbers in corn crops for the herbicide glyphosate which has all but replaced more dangerous pesticides since the introduction of roundup ready corn varieties. Across 5 different types of the chemical, here are the numbers between the two most recent surveys in 2010 and 2014:

Glyphosate decreased from 7,979,000lbs to 5,255,000lbs = -34%

G. Amm. Salt was at 46,000lbs in 2010 and withheld* in 2014 = -??%

G. Dim. Salt was withheld in 2010 and was at 3,604,000lbs in 2014. = +??%

G. Iso. Salt decreased from 57,536,000lbs to 27,221,000lbs = -52%

G. Pot. Salt increased from 1,522,000lbs to 22,560,000lbs = +1382%

*(D) “Withheld to avoid disclosing data for individual operations”

In summary, comparing the years 2010 and 2014 for 5 glyphosate products:

across 3 products which decreased in their use, a total decrease of 2,724,000+1 farm+30,315,000 = 33,039,000lbs+;

and across 2 products which increased in use, a total increase of 21,038,000+ (3,604,000 — 1 farm)=24,642,000lbs — ;

resulting in a net decrease of approx. 8,397,000 million pounds of glyphosate products. Whether that’s significant or not is up to you or anyone reading this.

I picked this pesticide because I hear about it so much. I haven’t looked into any others, and this is obviously not a representation of the entire landscape of pesticide use. Along with this however, examining the alternative pest management practices which are also reported, relevant market information, and knowing the pesticides that glyphosate has helped replace and their weight numbers over the years would help to paint a better picture of why exactly this trend is happening rather than just the raw data.
