Abstract:

Les diatomées sont des microalgues ubiquistes d'une diversité exceptionnelle. Cela en fait de bons indicateurs de la qualité des écosystèmes aquatiques et sont utilisées depuis plus de 50 ans. Depuis l'année 2000, la Directive Cadre Européenne sur l'Eau impose leur utilisation pour évaluer la qualité écologique des cours d'eau. Un cadre typologique doit être utilisé afin de comparer des rivières comparables entre elles, c'est-à-dire des rivières de mêmes régions bioclimatiques, coulant sur les mêmes substrats géologiques et à des altitudes comparables.

Abstract:

In agricultural watersheds, streams are intimately connected with croplands and may be inadvertently exposed to agrochemicals such as fertilizers and herbicides. Riparian plants and aquatic primary producers (aquatic plants, phytoplankton and periphyton) may be particularly affected by agrochemicals due to their taxonomic similarity to the intended targets (crop and weed species). The overall objective of this thesis was to assess the effects of fertilizers and the herbicide atrazine on riparian plants and aquatic primary producers. Effects were assessed across varying scales of observation

Abstract:

Nitrodiphenyl ether (NDPE) and related herbicides cause light and oxygen-dependent lipid peroxidation in susceptible green plants and algae. The exact mode of action of these herbicides has not yet been clearly established. Experiments with the alga Scenedesmus obliquus indicate that the role of photosynthetic electron transport is principally to generate the oxygen required for NDPE toxicity, rather than having a more direct involvement. DPE I an experimental NDPE, did not induce lipid peroxidation or chlorophyll bleaching in the alga Chlamydomonas reinhardtii but the herbicide did inhibit gr

Arbuscular mycorrhizal fungi (AMF) play a crucial role in improving the growth of a vast majority of plants.

Arbuscular mycorrhizal fungi are reported to enhance plant nutrient uptake, stress tolerance, and soil aggregate formation which are key aspects of productive low-input farming. The objective of this study was to investigate the effects of four pesticides on the ability of AMF to colonize the roots of okra plants (Abelmoschus esculentus). The pesticides being tested i

Abstract:

Pollution of water by herbicides and heavy metals has caused world wide concern because of the adverse effects of these pollutants on the environment, humans and wildlife. This has resulted in tighter legislation being imposed on the levels of these pollutants in drinking water. For example, the European Union (EU) has set the legislation in the drinking water Directive Admissible Concentration for a single herbicide to a maximum of 0.1 ppb. Despite the tight environmental pollution controls, isolated cases of pollutants exceeding their limits are still encountered. This would suggest that res

Abstract:

Master of Science<br>Department of Agronomy<br>Antonio R. Asebedo<br>Johanna A. Dille<br>Field experiments were conducted in 2016 and 2017 across nine locations in Kansas to develop and evaluate a procedure for variable-rate applications (VRA) of soil-applied herbicides in corn and grain sorghum based on soil properties. Soil electrical conductivity (EC) and soil organic matter (SOM) data were collected at each location using a Veris MSP3. Soil EC was correlated to soil texture and herbicide algorithms were developed for two different tank-mixes for corn and for grain sorghum. Three algorithms
