Background: Herbicides are widely used in agriculture to kill a large variety of unwanted weeds. However, the application in water ecosystems may pose harmful impacts on the health of aquatic organisms. We studied the acute toxicity of four major types of herbicides on the survival of adult shrimp, Artemia franciscana (AF). Methods: The brine shrimp, AF, was hatched from the commercially encys...

HIGHLIGHTS The longevity of the female and male Drosophila melanogaster is improved at doses given Aloe vera. Trifluralin has been observed to cause DNA damage, while vera shown reduce damage. reduced larval survival rate, increased rate high concentration.

Interaction between herbicides and sediments in water systems is an important process occurring in water, which influences the behaviour of the herbicides in water. This paper reports on the sorption of herbicides norflurazon, oxadiazon and trifluralin on soil and the interaction between the herbicides and sediments under stirred and non-stirred conditions. The sorption coefficients of the herb...

Background: Evaluation of herbicide pollution in aquatic environments needs the great concern and the most important echo-pollutant effects of herbicides are related to their effects on non target aquatic organisms. Native fish can serve as a proper bio-indicator for evaluation  of pollution on aquatic ecosystems. OBJECTIVES: To find environmentally friendly herbicides, in this study the acute ...

cation as the layby treatment. Such herbicide treatments follow the last cultivation before harvest. Shading and With adoption of combine harvest technology, massive sugarcane competition from sugarcane plants usually control weeds (Saccharum Spp. Hyb.) residue is left on the soil surface following each harvest, which could affect the environmental fate and efficacy developing after canopy clos...

background: trifluralin is a herbicide and used in agriculture widely. it enters plants through developing roots and stops plant cells from division and elongation (meristemic inhibitor). extensive application of trifluralin to control annual grasses and broadleaf weeds in agriculture, horticulture and horn garden, leads to environmental pollution and its entrance into the food chain could have...

Abstract The objective of this work was to evaluate the effectiveness and selectivity herbicides applied at preemergence melon (Cucumis melo) crop. experiments were carried out from 2017 2018, in a randomized complete block design, with four replicates, state Rio Grande do Norte, Brazil. treatments consisted application of: 35 g ha-1 a.i. flumioxazin, 25 250 sulfentrazone, 480 metribuzin, 240 o...

The species Rottboellia exaltata L. (itchgrass) has become an important weed in cultivated areas, requiring management studies to enhance its control. This study aimed evaluate the effectiveness of herbicides pendimethalin (1200 g ha−1), clomazone (1000 indaziflam (100 and trifluralin (900 ha−1) applied pre-emergence association with diquat (400 glyphosate (1175 addition their isolated applicat...
