1. Characterization of propargyl bromide transformation in soil

Author:
Papiernik, Sharon K.; Gan, Jianying; Yates, Scott R.

Subject:
alcohols; bromine; carbon; correlation; fumigants; hydrolysis; pest management; pollution; soil; soil organic matter
Abstract:
... Propargyl bromide is being investigated for its potential as a soil fumigant. Characterization of the fate of propargyl bromide in soil is important in determining both efficacy and the threat of environmental contamination. These experiments investigated some of the factors affecting the rate of propargyl bromide degradation in soil and quantified some of the products formed as a result of propar ...

Magnaporthe grisea; antifungal properties; blast disease; equations; fungi; fungicides; hydrophobicity; inhibitory concentration 50; phytoalexins; quantitative analysis; quantitative structure-activity relationships
Abstract:
... Phytoalexins are low-molecular-weight chemicals that immune systems of plants produce and accumulate in response to infections, especially those of fungal origin. Although their content is not high in plants, yet they have shown unique fungicidal activity and played an important role in the defence system of plants. In searching for novel environmentally benign fungicides with high activity, the s ...

Abstract:
... Factors affecting the efficacy of an attracticide strategy for the control of the codling moth Cydia pomonella L (Lepidoptera: Tortricidae) were investigated using laboratory and field experiments. The sex-pheromone-based insect-control strategy utilises 100-µl droplets of a sticky, paste-like formulation containing 1 mg g−1 (E,E)-8,10-dodecadien-1-ol (codlemone) as an attractant for male moths an ...

Abstract:
... During a 6-year study, effects of two contrasting regimes of pesticide use on pitfall and suction catches of Collembola were monitored in an arable field under a rotation of grass and winter wheat. Current farm practice (CFP) represented conventional fungicide and herbicide use plus applications of organophosphorus (OP) insecticides, whereas reduced input approach (RIA) utilised minimum inputs of ...

Abstract:
... Over 800 pesticides are currently approved for use in one or more EU countries. The maximum residue levels (MRL) for agricultural pesticides are derived from field trials conducted under good agricultural practice (GAP). The MRL is a legally enforceable limit related to GAP. The results from field trials would only be used to establish MRLs if the estimated intake of residues did not exceed the ac ...

Abstract:
... BAS 662H, a 1:2.5 combination of the semicarbazone-type auxin transport inhibitor diflufenzopyr and the auxin herbicide dicamba, is used as a post-emergence herbicide in corn. The combination has been observed to provide more effective broadleaf weed control and improved tolerance in corn than typical rates of dicamba used alone. In order to analyze this phenomenon, the uptake, translocation, meta ...
