Pest information from traditional cotton-producing states must be adjusted for Kansas because:

• A. pests are not the same
• B. Kansas has more pests
• C. Kansas has fewer pests
• D. growing season is shorter

Answer: (D)

The main idea here is that pest development and the right timing for control depend on the local climate, especially how long the growing season lasts. Kansas has a shorter growing season than the traditional cotton states, so pests and the crop reach vulnerable stages on a different schedule. Pests respond to heat units (degree-days), and with fewer of these units available in Kansas, pest generations may be fewer and their peak activity may shift relative to the crop’s growth stages. Because of this, pest information from cotton states can’t be applied exactly as-is; you must adjust guidance to Kansas using local degree-day models, scouting data, and Kansas-specific thresholds to time applications correctly and protect the crop efficiently.
