For pesticides to effectively manage pests, they must first be deposited on the target (typically a plant surface) in manner which active ingredient(s) can readily taken up by organism. A architectural model that enables location of various components 3-D space combined with particle trajectory has been used study interception spray droplets vegetative elements. Results from simulation are compared wind tunnel studies glyphosate deposition cotton (Gossypium hirsutum L. var. Sicala), sow...
ABSTRACT This paper presents results from field studies carried out during the 1993–1998 Australian cotton ( Gossypium hirsutum L.) seasons to monitor off‐target droplet movement of endosulfan (6,7,8,9,10,10‐hexachloro‐1,5,5a,6,9,9a‐hexahydro‐6,9‐methano‐2,4,3‐benzodioxathiepin 3‐oxide) insecticide applied a commercial crop. Averaged over wide range conditions, deposition 500 m downwind boundary was approximately 2% field‐applied rate with oil‐based applications and 1% water‐based...
Realistic virtual models of leaf surfaces are important for several applications in the plant sciences, such as modelling agrichemical spray droplet movement and spreading on surface. In this context, required to be smooth enough facilitate use mathematical equations that govern motion droplet. Although an effective approach is apply discrete smoothing D2-spline algorithms reconstruct from three-dimensional scanned data, difficulties arise when dealing with wheat (Triticum aestivum L.)...
Previous research has sought to adopt the use of drift-reducing technologies (DRTs) for in field trials control diamondback moth (DBM) Plutella xylostella (L.) (Lepidoptera: Plutellidae) canola (Brassica napus L.). studies observed no difference canopy penetration from fine coarse sprays, but coverage was higher sprays. DBM a strong propensity avoid sprayed plant material, putting further pressure on selecting that maximise coverage, often this is at expense greater drift potential. This...
With greater environmental awareness, the movement of pesticides within and off a spray target area is acritical public concern. Ideally, all material applied should be deposited t ...
Drift of aerially applied forest herbicides can result in chemical deposition to streams. Riparian vegetation is expected attenuate drift, but there little corresponding data. A field study was conducted the Coast Range west Corvallis, Oregon, evaluate effectiveness forested riparian buffers. The buffers studied are typical those used for small and medium fish-bearing streams western Oregon as mandated by Forest Practices Act. helicopter sprayed two tracers over four transects. Twenty trials...
Abstract An extensive field study has been undertaken to quantify the aerial release of spray material through changes in meteorology as day progresses. important subset these collected data is one-second interval aircraft behavior and mechanical systems. These unique provide an excellent source information on bounding variability expected deposition patterns, how this might impact any error bounds established around time-averaged predictions generated by AGDISP model. This paper quantifies...
