The timely and accurate identification of stripe rust leaf is essential in effective disease control the safe production wheat worldwide. To investigate methods for identifying two diseases on different varieties based image processing technology, single-leaf images varieties, acquired under field laboratory environmental conditions, were processed. After scaling, median filtering, morphologica...

A new species of dart fish, Parioglossus galzini sp. nov., is described based on specimens collected in Haurei Bay, Rapa Island (French Polynesia). It is distinguished from all other described species of Parioglossus as follows: dark lateral body stripe absent, 100 or more scales in longitudinal series from above pectoral-fin base to base of caudal fin, pectoral-fin rays 19–21, membrane of firs...

been widely used to characterize foliar disease resistance (Jeger and Viljanen-Rollinson, 2001) because it Slow leaf-rusting resistance in wheat (Triticum aestivum L) is gainreflects both severity and rate of disease development ing acceptance as a breeding objective because of its durability in comparison with race-specific resistance. CI 13227 was previously (Wilcoxson et al., 1975). IR and I...

Rice (Oryza sativa L.) is the only widely cultivated gramineous crops that cannot be infected by rust fungi. To decipher the molecular basis of rice nonhost resistance (NHR) to Puccinia striiformis f. sp. tritici (Pst), the causal agent of wheat stripe rust, proteomic analysis was performed using the two-dimensional electrophoresis (2-DE) technique. The expressed proteins from rice leaves 24 an...

Unmanned aerial vehicles (UAVs) have the potential to monitor health status of several crop fields a farmer in full coverage. For complete and fast monitoring, however, high flight altitudes are usually needed, especially if large areas should be observed short time intervals. In this case, resolution on ground becomes insufficient detect specific symptoms diseases because submillimeter scale i...

Pepper yellow mosaic virus on Petunia hybrida, bean Viola odorata and Narcissus stripe cyclamineus were identified in Brazil using RT-PCR. Serology, mechanical transmission, host range, electron microscopy used to study the viruses further.

For the problem of multi-dimensional feature redundancy in remote sensing detection wheat stripe rust using reflectance spectrum and solar-induced chlorophyll fluorescence (SIF), a selection disease index (DI) monitoring model combining mRMR XGBoost algorithm was proposed this study. Firstly, characteristic wavelengths selected by successive projections (SPA) were combined with vegetation indic...
