- Abstract:
- ... Production models of a USDA-developed aerial electrostatic spray application system are currently being marketed in the US and abroad. Spray deposit and insect mortality studies conducted on cotton with the USDA prototype are summarized. Spray deposits with the electrostatic system were higher than with conventional aerial application systems. The increased deposits with the electrostatic system d ...

- Abstract:
- ... Transmittance spectra (500 to 950 nm) and reflectance spectra (550 to 1700 nm) were analyzed to determine if they could be used to distinguish aflatoxin contamination in single whole corn kernels. Spectra were obtained on whole corn kernels exhibiting various levels of bright greenish-yellow fluorescence. Afterwards, each kernel was analyzed for aflatoxin following the USDA-FGIS Aflatest affinity ...

- Abstract:
- ... Sediment and its associated pollutants entering a water body can be very destructive to the health of that system. Best Management Practices (BMPs) can be used to reduce these pollutants, but understanding the most effective practices is very difficult. Watershed models are the most cost-effective tools to aid in the decision-making process of selecting the BMP that is most effective in reducing t ...

- Abstract:
- ... The objective of this research was to study the potential of near-infrared (NIR) reflectance spectroscopy as a means for nondestructive measurement of the firmness and sugar content of sweet cherries. NIR spectral data were collected from Hedelfinger and Sam sweet cherries in the spectral region between 800 nm and 1700 nm. Statistical models were developed using the partial least square method to ...

- Abstract:
- ... Herbicide detection in surface water sources has caused concern about contamination of these sources and adverse effects on human and aquatic health. Understanding surface water herbicide transport from agriculturally intensive watersheds is useful for development of herbicide best management practices to reduce off-site movement. The seasonal occurrence and load of five herbicides exported by a s ...
