Simulation-aided study of herbicide patch spraying: Influence of spraying features and weed spatial distributions
نویسندگان
چکیده
Patch spraying is a technological way to reduce herbicide amounts required control weeds by triggering only where lie. Nevertheless, the adoption rate of this technology farmers still low and there lack efficient tools assess patch applications depending on features weed spatial distributions. To avoid unrealistic in-field experiments, virtual sprayer designed computer simulations are carried out quantify reduction possibilities ability apply right patches ensure efficiency. The spray application simulator combines theoretical description using various boom section widths (from 0.5 24 m) with experimental data describing nozzle patterns obtained from three commercial nozzles. Virtual infestation maps random locations aggregation degrees modelled different coverage rates elliptical sizes. Simulation results analysed through two performance indicators: i) ratio compared uniform broadcast (on entire field area), ii) proportion area which higher than 85% prescribed rate. Computer enable estimate simplified relationship use as function rate, size width. This demonstrates that provide practical resolution reach given target according distribution. Simulations also demonstrate narrow equipped traditional nozzles leads significant areas exposed under-application in case small patches.

GIS-aided planning of insecticide spraying to control dengue transmission
BACKGROUND The purpose of this paper is to integrate a multi-objective integer programming formulation and geographic information system (GIS) into dynamically planning the insecticide spraying area for preventing the transmission of dengue fever. METHODS The optimal spraying area to combat dengue infections is calculated by the multi-objective integer programming model using the dengue epide...
متن کاملDevelopment and Evaluation of a Real Time Site-Specific Inter-Row Weed Management System
ABSTRACT- A real-time, site-specific, machine-vision based, inter-row patch herbicide application system was developed and evaluated. The image resolution was 640 × 480 pixels covering a total area of 350 mm x 240 mm of a field composed of four quadrants of 350 mm x 60 mm each. The image frames were processed by LabView® and MatLab®. The developed algorithm, based on weed coverage ratio and seg...
متن کاملJIT Spraying and Mitigations
With the discovery of new exploit techniques, novel protection mechanisms are needed as well. Mitigations like DEP (Data Execution Prevention) or ASLR (Address Space Layout Randomization) created a significantly more difficult environment for exploitation. Attackers, however, have recently researched new exploitation methods which are capable of bypassing the operating system’s memory mitigatio...
متن کاملImpact of Grassland Reseeding, Herbicide Spraying and Ploughing on Diversity and Abundance of Soil Arthropods
In order to determine the interactive effect of reseeding, herbicide spraying and ploughing on soil fauna communities, we conducted a grassland reseeding experiment combined with pre-reseed management to examine how with the whole reseeding process affects soil faunal composition. Sampling occasions and exact treatments were as follows: (1) before chemical herbicide spray; (2) after spray but b...
