Movement and persistence of imazaquin,
oxyfluorfen, flurochloridone and terbacil in soil.
MILANOVA S, GRIGOROV P
Plant Prot. Inst., Kostinbrod-2230, Bulgaria.
The movement and persistence of imazaquin, oxyfluorfen, flurochloridone
and terbacil residues were studied using a bioassay based on
the shoot growth of Raphanus sativus L. var. radicula DC (radish)
in a sandy loam soil under field conditions in 1992 and 1993.
Imazaquin (0.3 kg a.i. ha-1) was more mobile in the sod than
the other three compounds. In 1992, under heavy rainfall conditions,
the herbicide was distributed down to 60 cm in amounts of about
0.01 mg kg-1. Conversely, in the dry year of 1993, the maximum
depth of penetration was 20 cm and persistence in the surface
soil layer (0-5 cm) was greater. After the first month in 1992,
residues of terbacil were distributed in the 0-20 cm layer,
and after 2, 3 and 5 months the herbicide had penetrated to
a depth of 40 cm. In 1993, terbacil residues were distributed
in the 0-10 cm layer only. In both years,
residues of flurochloridone (1.0 kg a.i. ha-1) were located
mainly in the 0-5 cm layer, but there was some penetrati

Hydrolysis and photodegradation of the
herbicide flurochloridone.

The degradation during hydrolysis and photolysis of flurochloridone,
a weed-killer, which belongs to the chemical class of pyrrolidones
was studied in diluted solutions. Hydrolysis reactions, carried
out on a large pH scale (from 5.5 to 9.5) and for temperatures
ranging from 20ê C to 40ê C, demonstrated that there
was no significant elimination of flurochloridone. The decrease
of this compound was at the very most 2% or 3% for more than
100 days of hydrolysis.The presence of aquatic humic substances
had no effect on chemical stability of this molecule. In neutral
or basic medium, hydrolysis led to the epimerisation of the
molecule of flurochloridone. Thus, a thermodynamic equilibrium
(70/30) was obtained between the trans and cis epimerics. No
additional modification of the structure of this molecule could
be observed for long-lasting reactions. UV photolysis (253.7
nm) or polychromatic irradiation (metallic iodide lamp) allowed
a total removal of flurochloridone for sh [abstract truncated]

Phytotoxic persistence and microbiological
effects of flurochloridone in Finnish soils.

FIN.
The phytotoxic persistence and movement of flurochloridone
were studied via lettuce bioassays in sandy, clay and organic
soils at two locations in Finland. The phytotoxic effect was
greatest in sandy soils and least in organic soils. The phytotoxicity
persisted in the 0-5 cm layer at most 1 month after application
of 0.75 kg a.i. ha-1. A dose of 2.25 kg a.i. ha-1 caused growth
inhibition in the 0-5 cm layer of organic soils only for 1 day,
whereas in other soils growth inhibition was observed throughout
the growing season, and in some cases during the following summer.
In sandy soils phytotoxic effects were found in the 15-25 cm
layer at the end of the first or the second growing season.
Chemical analysis resulted in detection
of flurochloridone residues in the 15-25 cm layer in all soils.
Bleaching of plant tissues often persisted about 1 year longer
than growth inhibition, being thus
a more sensitive method to detect low residues. Growth

Mutagenesis of an amino acid responsible
in phytoene desaturase from Synechocystis for binding of the
bleaching herbicide norflurazon.

Synechocystis mutants were selected resistant against
the bleaching herbicide norflurazon. In vitro analysis
of phytoene desaturation demonstrated that they all possess
a resistant enzyme. Sequencing of the corresponding pds gene
revealed that three different point mutations were obtained.
In all cases, the same amino acid, Arg195, was modified either
into Cys, Pro, or Ser. The degree of resistance determined via
carotenoid formation in cells as well as cell-free phytoene
desaturation in the presence of norflurazon was highest when
Arg was changed to Ser. A modification to Pro or to Cys resulted
in a gradually less pronounced degree of resistance. Cross-resistance
toward other bleaching herbicides like fluridone, flurtamone,
or fluorochloridone was also studied. However, there was only
a slight resistance against fluridone in one and against flurtamone
in two of the mutants. In contrast to other cyanobacterial mutants
previously described, impairment of catalytic activities of
the mutated enzymes was negligible.

River-water biodegradation of surfactants
in liquid detergents and shampoos.
OKPOKWASILI GC, OLISA AO
Dep. Microbiol., Univ. Port Harcourt, P.M.B. 5323, Port Harcourt,
Nigeria.
Biodegradabilities of surfactants in four detergents namely
SDS, Teepol, Apollo, Spencer and Triton X-100, and two shampoos,
Flex and Rainbow, were assessed using the river-water die-away
method. The shampoos underwent a more rapid primary biodegradation
than the liquid detergents. The ease of the degradation over
a 12-day period followed the order - SDS (97%), Rainbow (85%),
Flex (79%), Spencer (79%), Apollo (77%), Triton X-100 (63%)
and Teepol(59%) and appears to be related to their sulphate
concentrations. A microbial consortium comprising the following
genera Vibrio, Flavobacterium, Klebsiella, Pseudomonas, Enterobacter,
Bacillus, Escherichia, Shigella, Citobacter, Proteus and Anaebena
- were found to effect the degradation. The detergents and shampoos
supported microbial growth in the following decreasing order;
Teepol, Spencer, Flex, Rainbow, Apollo and Triton X-100. It
is concluded that the detergent of shampoo that supports the
most microbial growth is not neces [abstract truncated]

Control of grass and sedge in Allegheny
(Pennsylvania, USA) hardwood stands with Roundup-residual herbicide
tank mixes.
HORSLEY SB
USDA Forest Service, Northeasten
Forest Experiment Station, P.O. Box 928, Warren, Pa. 16365.
A small plot experiment was carried out to investigate the
effect of forest floor disturbance on establishment of grasses
and sedges and to test whether addition of a residual herbicide
in tank mix with Roundup could reduce grass and sedge reinvasion.
Seven residual herbicides, each at three rates of application,
were tested against a Roundup control. Herbicides were Hyvar
X (bromacil), Karmex (diuron), Racer (fluorochloridone)
(R-40244)), Devrinol (napropamide), Surflan (oryzalin),
Oust (sulfometuron methyl), and Sinbar (terbacil). Herbicides
were applied on these dates of application at two northwestern
Pennsylvania sites. Half of each plot was mechanically disturbed
to simulate logging disturbance. Response data were collected
for 2 or 3 years after treatment application. Soil disturbance
was a significant factor in promoting emergence of grass and
sedge; most germination occurred during the growing season immediately
following treatment. Little grass or sedge emerged [abstract
