DropLeaf: a precision farming smartphone application for measuring pesticide spraying methods [PDF]

, 2020
Pesticide application has been heavily used in the cultivation of major crops, contributing to the increase of crop production over the past decades. However, their appropriate use and calibration of machines rely upon evaluation methodologies that can precisely estimate how well the pesticides' spraying covered the crops.

Review on Application of Drone in Spraying Pesticides and Fertilizers [PDF]

International Journal of Engineering Research & Technology (IJERT), Vol. 10 Issue 11, November-2021
In today's agriculture, there are far too many innovations involved. One of the emerging technologies is pesticide spraying using drones. Manual pesticide spraying has a number of negative consequences for the people who are involved in the spraying operation.

Low-cost spectrogram based counterfeit medicine detection [PDF]

arXiv, 2019
Contaminated substances such as counterfeit medication and food contami-nated with pesticide residue is a pandemic of utmost urgency. Spectroscopy and chromatography methods are often used but are expensive and complex and as such a need exists for a device that can be easily operated in developing commu-nities. We present a hacked visible spectrometer

On the Real-Time Semantic Segmentation of Aphid Clusters in the Wild [PDF]

arXiv, 2023
Aphid infestations can cause extensive damage to wheat and sorghum fields and spread plant viruses, resulting in significant yield losses in agriculture. To address this issue, farmers often rely on chemical pesticides, which are inefficiently applied over large areas of fields. As a result, a considerable amount of pesticide is wasted on areas without

On the paradox of pesticides [PDF]

arXiv, 2013
The paradox of pesticides was observed experimentally, which says that pesticides may dramatically increase the population of a pest when the pest has a natural predator. Here we use a mathematical model to study the paradox. We find that the timing for the application of pesticides is crucial for the resurgence or non-resurgence of the pests.

Modelling the inhibiting effect on a microbial pesticide model [PDF]

arXiv, 2022
Microbial pesticides can avoid many of negative effects of traditional chemical pesticides. To modelling the inhibiting effect, in this paper we propose a model of entomopathogenic nematodes killing the target insects, and inhibiting the birth rate of the target insects simultaneously.

A smartphone application to measure the quality of pest control spraying machines via image analysis [PDF]

, 2017
The need for higher agricultural productivity has demanded the intensive use of pesticides. However, their correct use depends on assessment methods that can accurately predict how well the pesticides' spraying covered the intended crop region. Some methods have been proposed in the literature, but their high cost and low portability harm their ...

Öffentliche Daten auf die nächste Stufe heben -- Vom RESTful Webservice für Pflanzenschutzmittelregistrierungsdaten zur anwendungsunabhängigen Ontologie (erweiterte Version) [PDF]

arXiv, 2023
During the application of chemical pesticides, distance requirements have to be considered. However, these have to be determined and considered by the farmer manually. To support the farmer the Pesticide Application Manager (PAM)-Projects were conducted and a decision support system was developed.

A Spectrometer as Simple as a CCD Detector [PDF]

arXiv, 2017
Spectroscopy is the most fundamental instruments in almost every field of modern science. Conventional spectrometer is based on the dispersion elements such as various gratings. An alternative way is based on the filters such as interference filters, plasmonic nanoresonators, or quantum dots.

Ecological-economic modelling of interactions between wild and commercial bees and pesticide use [PDF]

arXiv, 2015
The decline in extent of wild pollinators in recent years has been partly associated with changing farm practices and in particular with increasing pesticide use. In this paper we combine ecological modelling with economic analysis of a single farm output under the as- sumption that both pollination and pest control are essential inputs.
