Phytotoxicity in sorghum plants during the / growing season at 2 (A), 5 (B) and 10 (C) 14 (D), 20 (E) and 24 (F) days after application at distances (m) from the point of application (0.

Clomazone is an agricultural herbicide, and has been the active ingredient of products named "Command" and "Commence".The molecule consists of a 2-chlorobenzyl group bound to a N-O Appearance: white solid. The mobility of clomazone [2-(2-chlorobenzylo)-4,4-dimetylo-1,2-oxazolidinone] in a loamy sand soil and a sand soil was studied in a soil column under laboratory conditions.

Microbial degradation of Command is promoted by high soil moisture, warm temperature, and by increasing the pH to Degradation was faster in a sandy loam than in silt or clay loams. volatility of clomazone as affected by soil moisture and temperature book In field. The mobility of clomazone [2-(2-chlorobenzylo)-4,4-dimetylo-1,2-oxazolidinone] in a loamy sand soil and a sand soil was studied in a soil column under laboratory conditions.

Commercial clomazone Cited by: 1. Half life in soil - days. Half life in water - 5 days. It has an EPA classification for soil mobility that ranges from Ground water contamination. Medium likelihood of leaching in the top 10 cm soil.

Velvetleaf (Abutilon theophrasti Medik.) was used as a bioindicator to examine factors (temperature, soil moisture, soil incorporation) which might influence clomazone {2-[(2-chlorophenyl)methyl] -4,4 Cited by: 8.

Clomazone {2-[(2-chlorofphenyl) methyl] dimethylisoxazolidinone)} is considered a pre-herbicide, because it must be activated by the target plant by means of metabolism, which converts the molecule.

A wind tunnel system was used for the investigation of the volatility of triallate under controlled conditions. The tunnel section was designed to optimise a horizontal flux, which is estimated by means of a Cited by: 8. where ρ is air density; C D is a “drag” coefficient that depends on wind speed, atmospheric stability, and surface roughness; U is the near-surface wind speed; q sat (T s) is the saturation Cited by: 4.

the total soil moisture, in fact, affects the quality of the forecast for several days, while an incorrect superficial soil moisture has a shorter impact, typically 1 day long, since it is restored by the total soil.

Clomazone Stewardship Generally warm temperatures and moist soil at or shortly after application increase the potential for volatilisation. DO NOT leave the sprayer standing overnight with spray in it File Size: KB. A simple off-line LSS is presented that can reproduce the soil moisture simulations of various AOGCMs, based on their modeled temperature and precipitation.

The scheme makes use of the well-established Cited by: 4. The model changes eliminate to a large extent the systematic 2 m temperature biases for the winter of / over Europe and make the soil temperature evolution much more realistic.

Herbicide Volatilization Herbicide Drift. Pesticides have also been reported to influence mineralization of soil organic matter, which is a key soil property that determines the soil quality and productivity.

At each gas sampling, air temperature and soil tem-perature at 5 cm depth and soil VWC content at 5 cm depth were measured simultaneously, using a digital Thermometer (JMCited by:   An increase in weather volatility means that bacteria and other microorganisms can become more active earlier than normal.

"We might get this really warm weather that we usually don't. Variation in soil moisture content can change metal availability.

However, the effects of soil drying during wetting-drying cycles on metal availability have been little investigated. Metal availability to an. Clomazone; ; matrix: soil; This is a field study of clomazone, the active ingredient in Command 3ME Herbicide, being developed for registration on rice.

This was done as an aquatic field dissipation. the moisture status of the surface layer of soil in the vegetation period [Bac et al. Hence, the knowledge on the values of volumetric moisture of soil is extremely important.

Wang. Coville]. Time-lapse, two-dimensional electrical resistivity measurements, which can detect changes due to soil moisture, were conducted to capture subsurface moisture changes across the ecotone, from Cited by: 6.

Although according to the metabolism studies and residue trials supporting the existing uses and performed with soil treatment, residues in the harvested commodities were below the LOQ Author: Alba Brancato, Daniela Brocca, Luis Carrasco Cabrera, Chloe De Lentdecker, Zoltan Erdos, Lucien Ferr.

Nitrous oxide (N 2 O) is a potent greenhouse gas that can result in nitrogen loss from the soil. The scientific literature is deficient in studies that measure N 2 O emissions, NO 3 leaching, and crop. The volatility distribution itself will depend on the temperature and the oxidants (for example, NO x will hinder the formation of ELVOC, lowering the yield 17).

But the approach proposed Cited by: Rainfall Induced Soil Slope Failure: Stability Analysis and Probabilistic Assessment integrates probabilistic approaches with the geotechnical modeling of slope failures under rainfall conditions with Cited by: volatility suggest that the impacts on poverty could also be large and heterogeneous.

To quantify the vulnerability of developing countries to being impoverished by current climate volatility we focus on the. The reliable measurement of negative pore water pressures is demanding as the growth of pre-existing bubbles, air-entry, or nucleation will all result in erroneous observations of soil suction.
