Q: According to this study by the University of Illinois, non GMO crops are producing greater yields than your GMO corn. Can you confirm or deny these findings? http://www.spectrumseed.com/sites/default/files/performance-trials/pdf/2013%20University%...

A: It is quite possible to have a high yielding variety that isn't GM. In the absence of insects, weeds, drought or some other environmental challenge, GM varieties don't necessarily yield any better, and if overall genetics are better in a non-GM variety, it will produce a higher yield. One therefore needs to know how the test was done. For example if there were no corn borers, no weeds, and no root worms there would be no need for GM corn. If there was a drought and they didn't...

Q: Today, someone tweeted the following: "Did you know? With the introduction of GMOs in our food, pesticide use went from 1.5 million pounds in 1999 to 90 million pounds in 2011." Is this accurate and/or can you clarify?

A: Moderator: A very thorough assessment of this research is linked here and highlights several flaws, inaccuracies, assumptions, and misleading use of data (available here): A review and assessment of ‘Impact of genetically engineered crops on pesticide use in the US – the first sixteen years: Benbrook C (2012)’ –Environmental Sciences Europe vol 24: 24 (September 2012); Graham Brookes, PG Economics, UK; Janet Carpenter, J E Carpenter Consulting LLC; Dr Alan McHughen, University of California,...

A: Research has shown that the insecticidal proteins produced by insect-protected GM crops can be released into the soil. The proteins are released from the roots as they develop and from plant tissues and pollen in the soil as they decay. Therefore, assessment of the potential effects of these proteins on soil organisms is an important component of the regulatory review of insect-protected GM crops. Direct testing is conducted against earthworms and springtails, both of which... Continue Reading

A: I’ve heard and read the claim that genetically modified crops have led to increased use of pesticides. This hasn’t squared with my own experience, so I checked with a few neighbors and family members, still on and around the family farm where I grew up. These are farmers who are 100% GM – herbicide tolerant corn and soybeans, and insect control traits for both corn rootworm and corn borer in many of the corn hybrids they plant. And for either crop, pesticide use has been... Continue Reading
Q: One of the greatest concerns for those of us living in areas where the GMO companies are doing research is the large amount of Restricted Use Pesticides and Herbicides that are being applied in open field testing. I'm curious as to why the...

A: The need for insecticides on parent seed corn arises from the high value of the crop, and a need to protect the yield, and in Hawaii, there is consistent pest pressure. Among the most significant insect pests here are thrips (that vector a virus that infects the corn), and corn ear worm, the larvae of which attack and feed on the developing kernels. Both reduce yields; both need to be suppressed. The companies do apply pesticides for such insect pests. People have the impression that the... Continue Reading
