Pulse Irrigation Strategies for Poinsettias

An economic comparison of biological and conventional control strategies for whiteflies (Homoptera: Aleyrodidae) in greenhouse poinsettias.

The objective of this study was to evaluate the costs of biologically controlling infestations of silverleaf whitefly, Bemisia argentifolii Bellows & Perring, in New England greenhouse operations on poinsettia, Euphorbia pulcherrima Wild, ex Koltz, using the parasitic wasp Encarsia formosa Gahan (Nile Delta strain). Partial budget analysis was used to compare costs for conventional verses biolo...

Basic Strategies for Body MRI: Pulse Sequence

The abdomen and pelvis present an ensemble of problems for MR imaging. 1. There is a problem of contrast; there are an almost infinite variety of disease processes that can occur in the abdomen/pelvis, and no one sequence is ideal for all. 2. There is the problem of signal-to-noise and coverage; evaluation of the abdomen/pelvis often requires a large field-of-view 3. There are problems with com...

Irrigation Strategies to Minimize Nitrate Leaching for Drip Irrigated Tomatoes

A hierarchical partitioning method for optimizing irrigation strategies

Improving water efficiency in irrigated agriculture is a priority for better environmental and economic performance. It can be achieved by reducing the amount of water used and optimizing the timing of application. Among numerous methods, hybrid biophysical/decisional simulation models are effective tools for evaluating and comparing irrigation strategies under different weather conditions. How...
