Refuge

Types of refuge planting

 Refuge Planting is a when a crop is planted that does not have any biotechnology that is used to control insect pests.  This crop is planted within the same type of crop that does contain the biotechnology.  The purpose of this is to make sure insects do not become overly exposed and evolve to not be resistant to the biotechnology.  This will allow insects that become resistant and mate with those who are not to produce, but the offspring would help to preserve the effectiveness of the biotechnology because they would not be susceptible.

One article by the University of Illinois News Bureau found (in 2011)  that a significant number of farmers in Illinois did not intend to do refuge plantings.  This could hasten the resistance of organisms to crops modified with Bt.  In 2008 some estimated as many as 25% of farmers were disregarding EPA requirements.
