Camanducaia River is part of the Piracicaba watershed responsible for pumping water into Cantareira System, which one main sources metropolis São Paulo and Campinas, Brazil. Intensive use pesticides hilly topography represents a situation high risk river contamination. Therefore, samples from 12 locations were collected along its tributaries, over period 4 mo during rainy season, analyzed by GC-MS/MS or UPLC- MS/MS presence 46 pesticides. Seven (fipronil, methyl parathion, metolachlor,...
This study evaluates the effects of different levels sugarcane straw on soil surface transport by runoff water four herbicides: ametryn, diuron, hexazinone, and sulfentrazone. Two experiments were conducted in a set nine experimental plots. In first experiment, was cultivated no applied to soil. second with 0, 9, or 18 Mg ha-1 surface. The from natural rainfall collected reservoirs at lower end each plot occasions following application herbicides total volume plots dependent coverage straw,...
Sugarcane cultivation uses many chemical inputs to ensure good yields, which puts local water resources under pressure. Grey footprint (GWF) is a widely used indicator of the volume needed assimilate pollutant load in body. However, GWF relies on leaching runoff fractions, are empirically determined. We hypothesize that these fractions might not represent true magnitude Brazilian sugarcane environment and management practices can further reduce this fraction loaded into environment. In two...
Dentre os métodos disponíveis para avaliar o comportamento de agrotóxicos no solo, destacam-se método "batch" (análise em batelada) e deslocamento miscível. O objetivo deste estudo foi a sorção mobilidade do imazaquin solos com diferentes características químicas, físicas mineralógicas, utilizando as técnicas miscível "batch". Os ensaios foram realizados laboratório Ecotoxicologia Centro Energia Nuclear na Agricultura da Universidade São Paulo (CENA/USP), Piracicaba, Paulo. utilizados,...
The use of aerial application with electrostatic charge is an alternative to improve the quality insecticide applications in soybean crop. objective this study was evaluate drift and chemical control caterpillar stink bug complex promoted by crop, using spray system rotary atomizers. Thiamethoxam + Lambda cyhalothrin applied a Cessna 188 Ag Truck agricultural aircraft two treatments: SPE® system, 54 SPE-5 nozzles 10 L ha-1 rate, Travicar model® 05165 atomizer, 55° angle blades rate 20 ha-1....
Pesticide drift is an issue in modern farming, mainly for crops under constant spraying as soybeans. This study aimed at assessing and pest control aerial applications soybean crops. Hydraulic nozzles rotary atomizers, regulated to a wide spectrum of droplet sizes, sprayed thiamethoxam plus lambda-cyhalothrin using agricultural aircraft Ipanema 202A volume rate 20 L ha−1. Treatments consisted testing two devices: cage atomizer (Micronair AU 5000) with blade angles 65° larger droplets, angle...
The present study aimed to evaluate the risk assessment, median lethal concentration LC50-96h, development, and mortality of Nile tilapia Oreochromis niloticus larvae exposed atrazine after stress management. An LC50-96h trial was carried out using fish (n = 147; 8.5 ± 1.0 mg; seven larvae/aquarium), which were allocated randomly in 21 aquaria (1 L) five concentrations atrazine: 2, 4, 8, 16, 32 mg L−1 plus one control (without herbicide) a with solubility adjuvant (acetone). Temperature, pH,...
Herbicides are essential tools for the phytosanitary security of agricultural areas, but their excessive use can cause problems in production systems and have negative impacts on human health environment. The objective this study was to present discuss main causes behind increase herbicide commercialization Brazil between 2010 2020. Data from Brazilian pesticide database, provided by Instituto Brasileiro do Meio Ambiente e dos Recursos Naturais Renováveis (IBAMA), were used. In 2020, sold...
O presente estudo teve o objetivo de avaliar a sorção e dessorção do imazaquin em solos com diferentes características granulométricas, químicas mineralógicas por meio isotermas estudos cinética e, assim, quantificar histerese no processo sorção-dessorção. Os utilizados foram classificados como Latossolo Vermelho distroférrico (LVdf), Vermelho-Amarelo (LVA) Neossolo Quartzarênico (RQ). secos ao ar peneirados malha 2 mm, sendo então procedida à caracterização dessas amostras. A molécula...
