Detection, Distribution, and Quantification of Silicon in Floricultural Crops utilizing Three Distinct Analytical Methods
Silicon (Si) detection, distribution, and quantification in plants was compared using electron beam analysis (EBA; scanning electron microscopy coupled with energy dispersive X‐ray analysis),…
Heat Stress Decreases Levels of Nutrient-Uptake and -Assimilation Proteins in Tomato Roots
Increases in heat stress with global warming may decrease crop production, as well as nutritional quality, partly via effects on root nutrient relations.
SPRAY CHARACTERISTICS AND DRIFT REDUCTION POTENTIAL WITH AIR INDUCTION AND CONVENTIONAL FLAT-FAN NOZZLES
Spray drift potential, spray coverage, droplet size, and spray pattern width for various sizes of air induction and conventional flat-fan nozzles with equivalent orifice areas were investigated and…

These results demonstrated that the proper concentration of MSO, NIS or OSB in spray mixtures improved the homogeneity of spray coverage on both waxy and hairy leaf surfaces and could reduce pesticide use.
Visual and Image System Measurement of Spray Deposits Using Water-Sensitive Paper
Water–sensitive papers (WSP) were attached to leaves in nursery trees and sprayed with air–blast sprayers. Deposit patterns on the WSP were rated visually for coverage, from 0 (no spots) to 10…
Effects of Ozone on the Sporulation, Germination, and Pathogenicity of Botrytis cinerea
Results indicated that pathogenicity of Botrytis cinerea conidia infection than non-ozonized conidia based on total lesion remain viable when grown in vivo and in vitro in the presence area.
Biology, Ecology, and Management of Nonnative Ambrosia Beetles (Coleoptera: Curculionidae: Scolytinae) in Ornamental Plant Nurseries
This paper aims to demonstrate the efforts towards in-situ applicability of the U.S. Department of Agriculture’s (USDA) EMMARM, which aims to provide real-time information about the phytochemical properties of fruit trees and shrubs to help design and implement anti-freeze strategies.
A SPECIALLY DESIGNED AIR-ASSISTED SPRAYER TO IMPROVE SPRAY PENETRATION AND AIR JET VELOCITY DISTRIBUTION INSIDE DENSE NURSERY CROPS
New sprayers are needed to deliver droplets uniformly within dense nursery crops to obtain healthy and marketable plants in the nursery industry. An air-assisted sprayer with five-port nozzles was…
Coverage and Drift Produced by Air Induction and Conventional Hydraulic Nozzles Used for Orchard Applications
A conventional, axial-flow, air-blast orchard sprayer was used to make applications to the outside row of a semi-dwarf apple block. Fluorescent tracer was applied at the same rate using either…
Development of a Canopy Opener to Improve Spray Deposition and Coverage Inside Soybean Canopies: Part 2: Opener Design with Field Experiments
Conventional boom sprayers usually are not effective in delivering droplets to inner parts of dense target canopies, such as soybeans at growth stages from R3 to R5. An experimental mechanical canopy…
