Abstract The loss of important contact herbicides like paraquat opens opportunities for more potentially sustainable solutions demanded by consumers and organizations. Frequently, adequate weed control, the alternatives to classical synthetic products need well-defined executed labels even detailed use descriptions. One novel candidate with rare activity is a pelargonic acid ester methyl polyet...

The objective of this study was to improve the spraying efficiency and meet the demand of modern agricultural. A new generation of electrostatic sprayer which we designed realized the goals. The automatic controlling system is successfully designed. PLC (Programmable Logic Controller) was taken as the control core of the system and LCD touch screen was employed for human-computer interaction in...

Aero-Pipeline Spraying System is a special ultra-working-width precision pesticide sprayer, which can broaden working scope, improve working efficiency, precisely transfer feed liquid to farm field that need to be sprayed, spray pesticides to crops in a very close range, and then improve working precision and reduce the losses of liquid materials such as pesticides. During the ultra-working-wid...

Agrochemicals, which are very efficacious in protecting crops, also cause environmental pollution and pose serious threats to farmers’ health upon exposure. In order cut down the human risks associated with agrochemical application, there is a need develop intelligent application equipment that could detect recognize crops/weeds, spray precise doses of at right place time. This paper presents m...

A tractor-operated automatic gun sprayer was developed for the cotton crop. The unit consists of frame structure, spray tank, horizontal triplex pump, control valves, nozzle, pressure gauge, strainer, hydraulic agitator and actuating mechanism. power to drive HTP pump taken from tractor take off (PTO) through a belt pulley. mechanism motor worm gear reduction. Two motors with 0.5 kW each (12 V ...

Table 1. Effect of paclobutrazol (paclo) on plant height and number of leaves developed on hollyhock at 2, 4, or 6 weeks after treatment. All application techniques were designed to deliver 0.10 mg paclo/10-cm Our objective was to determine the efficacy of a given dosage of β-[(4-chlorophenyl)methyl]-α-(1,1-dimethylethyl)-1H1,2,4-triazole-1-ethanol [paclobutrazol (paclo)] applied using differin...

This paper presents an adjoint method for the calculation of remote sensitivities in supersonic flow. The goal is to develop a set of adjoint equations and their corresponding boundary conditions in order to quantify the influence of geometry modifications on the pressure distribution at an arbitrary location within the domain of interest. First, this paper presents the formulation and discreti...
