The soil-plant system can act as a prevailing zone of pesticide dissipation in agroecosystems, which may influence leaching following rainfall events. Here we examined the contribution leaching, and degradation widely used anilide pesticides planted unplanted mesocosms with contrasting vineyard forest soils. were spiked at 25 mg/kg acetochlor, alachlor, S-metolachlor, butachlor metalaxyl, follo...

Miscanthus, is a promising bioenergy crop, considered superior to other crops because of its higher water and nutrient use efficiency, cold tolerance, production biomass. Broadleaf weeds grass weeds, cause major problems in the Miscanthus field. A field experiment was conducted 2018 2019, assess effects pre-emergence (alachlor napropamide) post-emergence herbicides (nicosulfuron, dicamba, benta...

Pesticides are widely used for safeguarding agricultural yields and controlling malaria vectors, yet simultaneously unintentionally introduced in aquatic environments. To assess the severity of this pressure Lake Tana Basin (Ethiopia), we evaluated occurrence 17 pesticide residues lake, tributary rivers, associated wetlands during wet dry season, followed by a questionnaire. These questionnaire...

The efficiency in water treatment by granulated complexes formed from the clay bentonite with (i) micelles of cations octadecyltrimethyl-ammonium (ODTMA) or (ii) liposomes didodecyldimethyl-ammonium (DDAB) was investigated. bentonite–ODTMA were synthesized three variations: I. mass ratio 68/32, which resulted an excess positive charge half cation exchange capacity and is denoted “ordinary”; II....

EVALUATION OF AGROCHEMICALS IN SOIL CONVENTIONAL AND AGROECOLOGICAL AGRICULTURAL PRODUCTION SYSTEMS. At the Contestado Settlement, Lapa, PR, soil samples from agroecological and conventional environments were evaluated against agrochemicals alachlor, atrazine, chlorpyrifos trifluralin. For sampling, 3 depths considered, 10 points selected, 5 in an environment, with sampling frequency was at 2-m...

Dichloroacetamide safeners such as N,N-diallyl-2,2-dichloroacetamide and (R,S)-3-dichloroacetyl-2,2,5-trimethyl-l,3-oxazolidine protect maize (Zea mays) against injury from thiocarbamate and chloroacetanilide herbicides. Binding activity of tritium-labeled (R,S)-3-dichloroacetyl-2,2,5-trimethyl-l,3-oxazolidine (15 Ci/ mmol; referred to as [3H]Saf) was characterized in extracts of etiolated maiz...

Exposure to certain environmental toxicants may be associated with increased risk of developing diabetes. The authors' aim was to investigate the relation between lifetime exposure to specific agricultural pesticides and diabetes incidence among pesticide applicators. The study included 33,457 licensed applicators, predominantly non-Hispanic White males, enrolled in the Agricultural Health Stud...
