Factors affecting aerial spray drift in the Brazilian Cerrado
(2019-02-01)
Pesticides aerial application may results in the drift to neighboring areas if some application technology is not well executed. This phenomenon should be minimized to reduce environmental risks and agricultural production ...
SPECTRUM, VELOCITY AND DRIFT OF DROPLETS SPRAYED BY NOZZLES WITH AND WITHOUT AIR INDUCTION AND MINERAL OIL
(Soc Brasil Engenharia Agricola, 2017-05-01)
The aim of this study was to evaluate the spectrum, the velocity and the potential drift risk of droplets sprayed by nozzles with and without air induction, with the addition of mineral oil to the spray solution. The ...
Potential of adjuvants to reduce drift in agricultural spraying
(Associação Brasileira de Engenharia Agrícola (SBEA), 2013-10-01)
The reduction of pesticide spraying drift is still one of the major challenges in Brazilian agriculture. The aim of this study was to evaluate the potential of different adjuvant products, such as surfactants, drift ...
INFLUENCE OF GLYPHOSATE CONCENTRATIONS ON SPRAY SOLUTION PHYSICOCHEMICAL CHARACTERISTICS AND DRIFT POTENTIAL
(Soc Brasil Engenharia Agricola, 2020-01-01)
The herbicide glyphosate is sprayed with varying application volumes that result in different concentrations used in the spray solutions. Thus, this study aimed to evaluate the effect of glyphosate concentrations on the ...
Droplet Spectrum from CP Nozzles Affected by Pressure, Flat-Fan, and Deflection Angles in Aerial Applications of Glyphosate
(Astm International, 2019-01-01)
Spray classification based on droplet size has been used worldwide to characterize nozzles in relation to efficacy and drift potential. The objectives of this study were to evaluate the effect of pressure, flat angle of ...

Short-term effects of visitor trampling on macroinvertebrates in karst streams in an ecotourism region
(Springer, 2014-03-01)
In order to evaluate the potential risks of human visitation on macroinvertebrate communities in streams, we investigated the effect of trampling using two short-term experiments conducted in a Brazilian ecotourism karst ...
