Herbicidal Activity and Residual States of Metolachlor in Upland Soils
The residues of metolachlor [2chloro-2'-ethyl-N-(2-methoxy-l-methylethyl)6'-methylacetanilide] applied to a soybean field were determined separately as to water-soluble and water-insoluble ingredients and were found to fluctuate with precipitation. The half life of all metolachlor was calculated as 40 to 60 days in 1990 and 4 to 5 days in 1991. The half life of the water-soluble ingredients, ho...
متن کاملHerbicidal Activity of Mimosine and Its Derivatives
Mimosine [β-[N-(3-hydroxy-4-oxypyridyl)]-α-aminopropionic acid] is a non-protein amino acid, and is a major compound present in all plant parts of Mimosaceae, which includes Leucaena (Leucaena leucocephala), Leucaena glauca, and other legumes belonging to Mimosa spp.. Structurally, mimosine is an analog of dihydroxyphenylalanine with a 3-hydroxy-4-pyridone ring instead of a 3,4-dihydroxy-phenyl...
متن کاملdevelopment and implementation of an optimized control strategy for induction machine in an electric vehicle
in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
15 صفحه اولDissipation kinetics and residues analysis of pendimethalin in soil and maize under field conditions
Herbicides play an important role in the production of crops, but their residues may cause numerous human/environmental problems. Dissipation kinetics of pendimethalin and residues in soil, maize straw and cobs in winter maize under field conditions were studied by gas chromatograph-electron capture detector (GC-ECD). Dissipation followed the first order kinetics and accounted by a biphasic pat...
متن کاملDissipation of Acetochlor and Residue Analysis in Plants and Soil under Field Conditions
The present study was undertaken to determine the persistence of acetochlor under real field conditions at maize crop. The chloroacetanilide herbicide acetochlor was applied as a pre-emergent spray on maize crop at 3 days after sowing in the experimental field in Didactical Station Ezăreni. The herbicide acetochlor was identified and quantified from soil and maize plants based on accelerated so...
