Ive heard that some organic farmers would really like to be able to use biotech, and actually are appreciative of being able to benefit from a neighboring farms insect resistance, for example it helps their own field have less insects, too. Is that accurate?

AExpert Answer

It is not surprising that some organic farmers would like to be able to use biotech. There is a push by some academics for biotech to be part of the “green revolution,” including organics. After all, biotech, such as Bt crops, is a form of host-plant resistance, similar to traditional breeding for insect control. Moreover, Bt has been used in agriculture for over 50 years and is widely used in certified organic agriculture. So the scenario stated above, wherein an organic farmer benefits from a neighbor's farm that actively controls insect populations (does not have to be biotech or Bt crops; can be virtually any insect-control measure that reduces insect populations), has merit. Actually, the recipient of "free insect control" does not have to be an organic farmer. It could be any farmer who does not control the same insect species as rigorously as a neighbor. However, there are some caveats to this practice of using "free insect control":
 

  1. The insect population could be large enough that even if the population were suppressed in a neighbor¹s field, there would still be enough insects to damage neighboring fields.
  2. If the crop to protect has a very low ET (economic threshold‹the level of damage you can tolerate before you initiate some type of control), such as fresh market fruits and vegetables, where only a very small amount of damage can be tolerated, relying on insect population suppression solely by one¹s neighbors would be risky.

The term “GMO” typically refers to crops or animals that, through genetic engineering, have had a gene (or a few genes) from a different species inserted into their genome. This is by design to improve a crop or animal with genetic engineering. In fact, me and my colleagues recently published a paper on this very topic that addresses this very topic and gives more details on the plant selection practices used for GE crops.   However, you pick up on something very...

Nearly all foods today have been genetically modified or altered in some way over thousands of years through selective breeding. However, there are only 10 commercially available GMO crops in the U.S: soybeans, corn (field and sweet), canola, cotton, alfalfa, sugar beets, summer squash, papaya, potatoes and apples.   Below is a table outlining what year the nine crops became commercially available:   Squash 1995 Cotton 1996...

One of the great things about farming is our ability to grow many different crops, while at the same time having the choices to raise them in different fashions, with or without biotech in the crops, especially in crops like corn. This can also be challenging as we have to work with our neighbors to make sure what we are growing doesn't cause a negative effect on what they are growing. This can happen in many different instances.    We raise production seed corn,...
