Abstract:
Effects of Alternaria leaf spot (caused by Alternaria macrospora) on the yield components of Pima cotton (Gossypium barbadense) were examined in four field trials, for the lower (< 30–50 cm), middle (30–50 to 70–90 cm) and upper (>70–90 cm) layers of the canopy. The influence of the disease on yield was determined by comparing measurements taken in fungicide‐treated plots with those taken in untreated plots. Alternaria‐induced defoliation was most severe in the lower canopy layer and gradually decreased towards the upper canopy layers. Significantly fewer bolls (26·0%) were picked in untreated plots than in fungicide‐treated plots, but differences in average boll size (reduction of 1·07%) among the treatments were non‐significant. The relationship between disease intensity and the loss of bolls was linear. Of the differences in yield between fungicide‐treated and untreated plots, 43·5% was observed in the lower canopy layer, 37·6% in the middle canopy layer and only 18·9% in the upper canopy layer.
