Acala cotton (Gossypium hirsutum, var. Maxxa) was planted into a split-plot factorial design field trial on the Shafter Research and Extension Center, Shafter, CA. The two main treatments were optimum irrigation (Io) and stressed irrigation (Is) containing five levels of soil nitrogen availability (-100, -50, optimum, +50, and +100 lbs N/ac). The objective of this field trial was to determine i...

Cotton leaf curl virus (CLCuV) (Gemininiviridae: Begomovirus) is the causative agent of leaf curl disease in cotton plants (Gossypium hirsutum). CLCuV is exclusively transmitted by the whitefly species B. tabaci (Gennadius) (Hemiptera: Alerodidae). B. tabaci contains several biotypes which harbor dissimilar bacterial endo-symbiotic community. It is reported that these bacterial endosymbionts pr...
