Irrigation and storm water runoff from agricultural fields has the potential to cause impairment to downstream aquatic receiving systems. Over the last several years, scientists have discovered the benefit of using edge-of-field practices, such as vegetated agricultural drainage ditches, in the mitigation of pesticides and sediment. After demonstrating this practice's feasibility in California,...
Differences in the impact of irrigation with freshwater versus wastewater on the underlying shallow groundwater quality were investigated in the Coastal Aquifer of Israel. Seven research boreholes were drilled to the top-most 3–5 m of the saturated zone (the water table region-WTR) in the agricultural fields. The unsaturated zone and the WTR below the irrigated fields consist mainly of clayey s...
Aspergillus species are major causes of pre- and post-harvest degradation of agricultural products. During 2004-07, the presence and population of Aspergillus species were studied in various fields and orchards of Fars and Kerman Provinces. Soil samples were collected from 0-40 cm depth. Isolates were recovered from soil using modified Czapek, AFPA and SPDA media. Based on macroscopic and micro...
Background: Despite that has passed decades from sustainability issues, but we are still seeing that farmers misuse the sources of production, and agricultural policies do not fit with the environmental capacity of regions and being brilliant of the term self-sufficiency in among agricultural development policies. It seems all the levers so far have been used to achieve sustainability so should...
Fall is burning season in the wheat fields of eastern Washington State. To prepare for planting in 1998, farmers burned about 229,000 acres of wheat stubble, an increase over recent years. Although a tighter state permitting system substantially reduced the acreage burned in 1999, dean air activitists are concerned that the state has not tightened up enough. The fires are used to help control c...

BACKGROUND Zoonotic cutaneous leishmaniasis has long been endemic in Israel. In recent years reported incidence of cutaneous leishmaniasis increased and endemic transmission is being observed in a growing number of communities in regions previously considered free of the disease. Here we report the results of an intensive sand fly study carried out in a new endemic focus of Leishmania major. Th...
We investigated involvement of feral swine in contamination of agricultural fields and surface waterways with Escherichia coli O157:H7 after a nationwide outbreak traced to bagged spinach from California. Isolates from feral swine, cattle, surface water, sediment, and soil at 1 ranch were matched to the outbreak strain.
Faunistic and statistical analyses of species diversity of the mimercofauna and araneofauna associated with variously managed agricultural fields and adjacent forest fragments and their interactions with Carabidae and Staphylinidae (Coleoptera) are needed to identify the key species affecting the dynamics within the arthropod population affecting the agroecosystem. This knowledge is needed to d...
A French farmer developed invasive aspergillosis with azole-resistant Aspergillus fumigatus with the TR34/L98H mutation following a hematopoietic stem cell transplantation. He had worked in fungicide-sprayed fields where a non-genetically related A. fumigatus TR34/L98H isolate was collected. If azole resistance detection increases, voriconazole as first-line therapy might be questioned in agric...
