Powdery mildew (PM) is a typical disease in winter wheat which causes severe yield loss in China. To control the disease effectively, it is important to develop a disease forecasting model at a regional scale. In this study, the remotely sensed data that reflect crop vigor and habitat traits were adopted as candidate inputs in model development, including various vegetation indices, land surface temperature...
This study aims at characterizing wheat canopies caused by powdery mildew (Blumeria graminis f. sp. tritici) with multi-angular hyperspectral data. The filling stage (23 May, 2012) was chosen to achieve such a goal, considering that the disease can show distinctive symptoms during the months of May and June. A total of 37 sample plots were selected including 32 normal canopies and 5 diseased canopies...
Yellow rust (Puccinia striiformis f. sp. Tritici) and powdery mildew (Blumeria graminis) are two serious diseases that severely intimidated yield and grain quality of winter wheat around the world. Since the preferable habitat conditions of them are similar, there is a high possibility that both diseases occurred in field simultaneously. To facilitate a differentiation of control procedures (i.e....
Stripe Rust, caused by Puccinia striiformis f. sp. tritici, has emerged as one of the most destructive foliar diseases of winter wheat (Triticum aestivum L.) and caused great yield loss. The primary objective of this study is to identify the stress characteristics of wheat leaves caused by such a disease. After performing artificial inoculation of stripe rust, hundreds of leaves with different infections...
