Download or read book Multiple Metal Cations as Spray Deposit Tracers and Evaluation of the AGDISP Ground Boom Spray Drift Model written by J. A. Zabkiewicz and published by . This book was released on 2009 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: The determination of spray drift by agrichemicals in field applications is laborious and expensive. Dyes have been used as tracers to reduce workloads and costs, but these methods have technical drawbacks. Metal cations have also been used as tracers and this method is promising, especially if a number of distinct cations from consecutive spray applications can be collected cumulatively by the same collectors. This study evaluated the use of various water soluble metal cation salts and plastic tape as a cost-effective collector for spray drift deposits. Measured deposit values were compared with calculated outputs from the AGDISP ground boom spray drift model. The comparisons showed that AGDISP over estimated downwind deposition and under estimated deposition within the last swathe in the spray block. Increasing boom height above the canopy improved within spray block deposition estimates. Varying wind direction had negligible effect; increasing relative humidity gave greater deposition closer to the spray block. These trends are discussed, together with the pros and cons of the metal cation and plastic tape collector system.

This book was released on 2017-12-15 with total page 479 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is a compelling need for new drugs and efficient treatments against mosquito-borne diseases. Environmentally safe, but effective insecticides that address the problems of resistance are required. Computational Design of Chemicals for the Control of Mosquitoes and Their Diseases explains how the search for new substances effective against mosquitoes and their diseases has benefited from the use of in silico techniques. QSAR modeling is suited to identify the key structural features and/or physicochemical properties explaining an activity and to propose candidate molecules for further evaluation by laboratory tests. Homology modeling is useful to approximate the 3D structure of proteins of interest. Pharmacophore modeling is a powerful means to capture the chemical features responsible for an activity and to identify new potentially active compounds via the virtual screening of databases. Fugacity modeling and a wealth of other modeling paradigms are useful for risk assessment in vector borne disease control.

This book was released on 2022-07-06 with total page 420 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modeling Processes and Their Interactions in Cropping Systems A complete discussion of soil-plant-climate-management processes In Modeling Processes and Their Interactions in Cropping Systems: Challenges for the 21st Century, a team of distinguished researchers delivers a comprehensive and up-to-date scientific textbook devoted to teaching the modeling of soil-plant-climate-management processes at the upper undergraduate and graduate levels. The book emphasizes the new opportunities and paradigms available to modern lab and field researchers and aims to improve their understanding and quantification of individual processes and their interactions. The book helps readers quantify field research results in terms of the fundamental theory and concepts broadly generalizable beyond specific sites, as well as predict experimental results from knowledge of the fundamental factors that determine the environment and plant growth in different climates. Readers will also discover: An introduction to water and chemical transport in the soil matrix and macropores Explorations of heat transport, water balance, snowpack, and soil freezing Discussions of merging machine learning with APSIM models to improve the evaluation of the impact of climate extremes on wheat yields in Australia Examinations of the quantification and modeling of management effects on soil properties, including discussions of tillage, reconsolidation, crop residues, and crop management The book will be essential reading for anyone interested in the 2030 breakthroughs in agriculture identified by the National Academies of Sciences, Engineering, and Medicine.
