Certified Crop Advisor Practice Exam

Which of the following is a limitation of GM crops?

1. Short stature

2. High fertilizer needs

3. Lack of tolerance to wet soils

4. Lack of marketability in some countries

The correct answer is: Lack of marketability in some countries

The limitation of GM crops related to marketability is significant because many countries have strict regulations or outright bans on the importation of genetically modified organisms. This can restrict farmers' access to certain international markets and limit their potential income, despite the agronomic benefits that GM crops may provide. Consumers in some regions may also demand non-GMO products due to personal beliefs, environmental concerns, or health perceptions, further complicating market access for farmers who grow GM crops. While some GM crops may exhibit traits like short stature, high nutrient requirements, or a lack of tolerance to specific environmental conditions, these factors do not universally apply to all GM varieties and are not as wide-ranging as market acceptance issues. Marketability relates to consumer choices and regulatory environments, making it a substantial limitation for growers when considering which crops to plant.
