Droplet evaporation and spread on waxy and hairy leaves associated with type and concentration of adjuvants.
BACKGROUND Adjuvants can improve pesticide application efficiency and effectiveness. However, quantifications of the adjuvant-amended pesticide droplet actions on foliage, which could affectExpand
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 andExpand
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),Expand
Heat Stress Decreases Levels of Nutrient-Uptake and -Assimilation Proteins in Tomato Roots
Global warming will increase root heat stress, which is already common under certain conditions. Effects of heat stress on root nutrient uptake have rarely been examined in intact plants, but theExpand
Effects of Ozone on the Sporulation, Germination, and Pathogenicity of Botrytis cinerea
KRAUSE, C. R. and T. C. WEIDENSAUL. 1978. Effects of ozone on the sporulation, germination, and pathogenicity of Botrytis cinerea. Phytopathology 68:195-198. Studies were made to determine ifExpand
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 10Expand
Biology, Ecology, and Management of Nonnative Ambrosia Beetles (Coleoptera: Curculionidae: Scolytinae) in Ornamental Plant Nurseries
Floriculture and Nursery Research Initiative (USDA-FNRI); Horticultural Research Institute (HRI); USDA-ARS National Program 304-Crop Protection and Quarantine [3607-22000-012-00D]; American NurseryExpand
Original paper: Evaluation of ultrasonic sensor for variable-rate spray applications
Automatic variable-rate sprayers require accurate measurement of canopy size. An estimate of canopy size is made by measuring the distance to the canopy at several elevations above the ground; anExpand
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 wasExpand
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 canopyExpand
