Distinguishing Isolates Of Rotylenchulus Reniformis Endemic In Louisiana On The Basis Of Root-Associated Females And Egg Masses, Benjamin Mcinnes
Distinguishing Isolates Of Rotylenchulus Reniformis Endemic In Louisiana On The Basis Of Root-Associated Females And Egg Masses, Benjamin Mcinnes
LSU Master's Theses
The reniform nematode Rotylenchulus reniformis is a major pathogen of soybean and cotton in Louisiana. Previous studies have shown that populations of reniform nematode throughout the southern United States vary in reproduction and pathogenicity. Limited studies have been conducted to evaluate the reproduction and pathogenicity of populations of R. reniformis endemic in Louisiana. Studies with isolates of the nematode from eight cotton-producing parishes focused solely on reproduction of the root-associated infective and swollen female life stages with and without attached egg masses on the cotton genotypes MT2468 Ren3, M713 Ren5, and Stoneville 4946GLB2 and the soybean genotypes PI 548316, PI …
Impact Of Pre-Bloom Square Loss On Yield And Lint Quality In Louisiana Cotton Cropping Systems, Cory L. Cole
Impact Of Pre-Bloom Square Loss On Yield And Lint Quality In Louisiana Cotton Cropping Systems, Cory L. Cole
LSU Master's Theses
During the 2016 growing season, research was conducted at three locations in the state of Louisiana to evaluate the impact of pre-bloom square loss on cotton lint yield and fiber quality. Two cotton varieties, Phytogen 499 WRF and Phytogen 222 WRF were chosen up which to imitate early season square loss due to tarnished plant bug, Lygus lineolaris (Palisot de Beauvois) and/or cotton fleahopper, Pseudatomoscelis seriatus (Reuter) feeding or unfavorable weather conditions. Thirty plants within each plot were selected and squares were counted. Squares were assigned numbers, and numbers were then randomized using a computerized number generator. To simulate intervals …
