1 INTRODUCTION Cotton (Gossypium spp.) is the world's most widely cultivated natural fibre crop, underpinning global textile industries and rural economies.

1 INTRODUCTION The effectiveness of fungicides is an important concept in plant disease control, and the emergence of decreased fungicide sensitivity in fungal populations adds another level of complexity for disease management. Disease control strategies focus on managing inoculum and minimizing disease impact by planting the least susceptible varieties and implementing cultural practices.

Abstract Decreased sensitivity to fungicides impacts the effectiveness of fungicide applications for managing plant disease. Knowledge of the frequency of decreased sensitivity in field populations is critical for evaluating risks for disease control.
