Spray drifts have been studied by mathematical models and computer simulations as an
essential complement to lab and field tests, among which are fluid dynamic approaches that …

Plant protection unmanned aerial vehicles (UAVs), which are highly adapted to terrain and
capable of efficient low-altitude spraying, will be extensively used in agricultural production …

The computational fluid dynamics method based on the lattice Boltzmann method (LBM),
was used to simulate the downwash flow field of a quad-rotor drone. The downwash flow …

Purpose Pesticides are applied to agricultural fields to optimise crop yield and their global
use is substantial. Their consideration in life cycle assessment (LCA) is affected by important …

摘要近十年来, 我国植保无人飞机迅猛发展, 应用的农作物范围越来越广, 不仅在水稻, 小麦,
玉米等主要粮食作物得到了应用, 在橡胶, 槟榔等高大植株的病虫害防治中更有其独特优势 …

In crop protection, it is well known that droplet size determine spray efficacy. The
optimisation of both spray deposition and retention leads to a dilemma: should small …

Greenhouse crop production in China has in the recent years expanded widely. To minimize
compromised pesticide use and adverse environmental impact in these structures, it is …

Introduction In this study, we aimed to characterise exposure to pyrethroids,
organophosphates, and tebuconazole through multiple pathways in 110 parent–child pairs …

Highlights•Model developed based on 20 years' experimental drift data when spraying fruit
crops.•Innovative approach using continuous dependence of spray drift on crop growth …

Boom sprayer is widely used in large farm crops because of its high working efficiency and
favorable spraying effect. But there are still some problems in cotton defoliant spraying in …
