Heres an important question I'm sure everyone would be interested in. Is it true that insects are evolving and becoming resistant to gmo bug killing crops Is this true and how do your scientists feel about this affect these insects will have on the environment. Also if the seeds are no longer good for fighting off. Also what about Roundup ready crops starting to fail against weeds.

AExpert Answer

Resistance can and has evolved to all forms of pest management, including chemical, biological, and cultural tools, and is not a unique concern for biotech-derived crops. When resistance does occur within insect populations, this is an economic issue for growers because they need to identify and use other types of insect pest control measures in order to continue producing their crop. However, the development of resistance in an insect or weed population has no direct effect on the environment because the balance of evidence shows organisms behave the same as they did prior to being exposed to that particular pest control strategy. With the case of GM crops, however, the indirect effect on the environment may be important. Insect resistant and herbicide tolerant GM crops allow the more targeted use of milder insecticides and herbicides to produce the same crop yield and so insect or weed resistance may require the grower to shift back to using more or stronger crop protection products. For this reason, the industry has set up stewardship plans and guidelines to help slow the development of resistance in both insects and weeds.

Believe it or not, I jump at opportunities to talk about aquatic life, so thank you for your interest. I developed a passion for aquatic animals early on and remain grateful that I have managed to explore my passions in ecotoxicology for over 25 years! This is a very general question in terms of pesticide/herbicide options that are commercially available and as well as applications. I will focus on glyphosate and dicamba specifically. Two active ingredients in herbicidal formulations that... Read More

This discussion will focus on glyphosate and dicamba as examples of herbicides that are used to manage weed control on farms cultivating GM crops. As background, glyphosate binds strongly to soils limiting bioavailability and glyphosate rapidly... Read More

Many different short-term and long-term aquatic studies are required for pesticides during the registration process and these studies are used to evaluate if there are potential impacts to aquatic life. These required studies test for potential... Read More
