Abstract BACKGROUND Unmanned aerial vehicles (UAVs) are a recently developed spraying technology. However, the effect of spray volume variation on deposition and pesticide control efficacy is unknown. The three UAV volumes (9.0, 16.8 28.1 L ha −1 ) using different nozzle sizes droplet wheat aphid powdery mildew was assessed. An electric air‐pressure knapsack (EAP) sprayer used as comparison. RESULTS Different significantly influenced EAP. For UAV, low 9.0 with fine (nozzle LU120‐01) resulted...
Abstract This article is part of a series describing the development Spray Drift Task Force (SDTF) database and its application to agricultural chemical exposure risk assessment modeling. The describes large generic (assuming that active ingredient rate not factor affecting physical drift) use in estimating spray movement immediately following by aerial methods. components are described. In agreement with field trials open literature, shows major variables off-target deposition droplet size,...
Abstract It is difficult for the handheld/backpack or ground machinery to spray pineapple plant fields because profile relatively inaccessible. In this situation, unmanned aerial vehicles (UAVs) are a good choice easy access and no physical damage crops. Aerial quality optimum application parameter settings can be influenced by many factors such as UAV type, operating parameters, meteorological conditions, crop growth period, pest species. The objective of study was investigate effects...
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...
POST weed control in soybean the United States is difficult because resistance to herbicides has become more prominent. Herbicide applicators have grown accustomed low carrier volume rates that are typical with glyphosate applications. These volumes efficient for applications and allow treat a large number of hectares timely manner. Alternative modes action can require greater effectively weeds. Glyphosate, glufosinate, lactofen, fluazifop-P, 2,4-D were evaluated field greenhouse studies...
Spray drop size is a critical factor in the performance of any agrochemical solution and function spray solution, nozzle selection, operation. Applicators generally select particular based on reported by manufacturers researchers. Like most population sampling methods, accurate measurement sizing methodology, accuracy measurement, inferences about total from subset. Studies were conducted to determine repeatability standardized set nozzles at three different application technology research...
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...
The study was conducted at the University of Nebraska Pesticide Application and Technology Laboratory in North Platte, July 2015.Two application volume rates (100 200 l • ha -1 ) three nozzle types (XR, AIXR, TTI) were selected two flow (0.8 1.6 min a single speed 7.7 km h .Each collector type [Mylar washed (MW), Mylar image analysis (MIA), water-sensitive paper (WSP), Kromekote (KK)] arranged randomized complete block design.Each treatment replicated twice, providing six cards each for...
