Influence Of Silicon On The Development Of Anthracnose Of Grain Sorghum, Sanjay Pokhrel Jan 2016

Influence Of Silicon On The Development Of Anthracnose Of Grain Sorghum, Sanjay Pokhrel

LSU Master's Theses

To study the effect of Silicon (Si) with and without a fungicide on anthracnose development of sorghum, several experiments were conducted in the greenhouse and field. In the initial study, different Si rates [0 (control), 0 (lime control), 200, 400, 600, 800 kg Si/ha] were used in a low-Si Alfisol to determine if inoculum densities were affected by Si levels. No differences were observed between inoculum densities of 1*105 and 1*106 conidia/ml in affecting anthracnose development in the greenhouse. Anthracnose severity was found to be lowest in plants treated with 800 kg Si/ha, regardless of inoculum density. In another study, …
