What is a "resistant variety" in pest management?

• A. A crop variety bred to withstand specific pests or diseases effectively
• B. A method of applying pesticides on crops
• C. A type of pesticide that targets multiple pests
• D. A technique for increasing soil fertility

Answer: (A)

A "resistant variety" refers to a specific crop variety that has been genetically or selectively bred to withstand or deter certain pests or diseases effectively. This means that the plants possess traits that enable them to either resist infestation or recover from pest attacks more efficiently than non-resistant varieties. This approach is crucial in pest management because it reduces reliance on chemical pesticides, promotes sustainable agricultural practices, and can lead to higher yields in challenging environmental conditions.

Developing resistant varieties is a strategic way to integrate biological control into crop production, enhancing overall plant health and decreasing the potential for pest outbreaks. Such varieties play a significant role in pest management programs by contributing to long-term agricultural sustainability and food security.
