Metribuzin Persistence in Soil

Weed Science, 1977
The persistence of metribuzin [4-amino-6-tert-butyl-3-(methylthio)-as-triazine-5(4H)-one] in several soils from the lower alluvial floodplain of the Mississippi River was studied in the greenhouse and laboratory using bioassay and gas chromatographic methods of residue detection.

Soybean Tolerance to Metribuzin

Weed Science, 1973
Tolerance of greenhouse-grown soybean (Glycine max (L.) Merr.) to preemergence applications of 4-amino-6-tert-butyl-3-(methylthio)-as-triazin-5(4H)one (metribuzin) was greatly influenced by herbicide rate, soil organic matter, and simulated rainfall after treatment.

Effect of pH on Phytotoxicity of Metribuzin and Ethyl-metribuzin

Weed Technology, 1989
The influence of pH on the behavior of metribuzin and ethyl-metribuzin in soil and nutrient solution was studied. Toxicity of both herbicides to oats decreased as soil pH decreased from 8.4 to 4.2 in a sandy loam. Herbicide adsorption increased as soil pH decreased.

Loss of Metribuzin and Ethyl-metribuzin from Glass and Soil Surfaces

Weed Technology, 1989
The loss of metribuzin and ethyl-metribuzin from soil and glass surfaces was studied to determine if volatilization and/or photodegradation could explain inconsistent weed control with these herbicides. In growth chamber experiments, phytotoxicity of ethyl-metribuzin decreased as the time between surface application and initial watering increased ...

Effect of Trifluralin and Metribuzin Combinations on Soybean Tolerance to Metribuzin

Weed Science, 1977
In field trials, soybeans [Glycine max(L.) Merr.] treated with trifluralin [α,α,α-trifluoro-2,6-dinitro-N,N-dipropyl-p-toluidine] at 0.56 and 0.84 kg/ha were protected from injury by metribuzin [4-amino-6-tert-butyl-3-(methylthio-as-triazine-5(4H)one] at 0.28 to 1.12 kg/ha.

Metribuzin degradation in soil: I—effects of soybean residue amendment, metribuzin level, and soil depth

Pesticide Science, 1991
AbstractPlant residue and soil depth effects on metribuzin degradation were investigated. Dundee silt loam soil collected at depth increments of 0–10 cm (SUR) and 10–35 cm (SUB) was treated with labeled [5−14 C]metribuzin. Samples were assayed at several time points up to 140 days after treatment.

Tomato chloroplast photochemical sensitivity to metribuzin

Scientia Horticulturae, 1982
Abstract Differential tolerance of tomato cultivars to metribuzin at the chloroplast site of action was evaluated through in vitro studies. Isolated chloroplast preparations from 18- or 30-day-old seedlings of metribuzin-tolerant cultivars ‘Fireball’ and ‘Vision’, and metribuzin-susceptible ‘H1706’, were treated with varying concentrations of ...

Metribuzin metabolism by tomato cultivars with low, medium, and high levels of tolerance to metribuzin

Pesticide Biochemistry and Physiology, 1989
Abstract Metribuzin [4-amino-6-tert-butyl-3-(methylthio)-as-triazine-5(4H)one] metabolism by the tomato (Lycopersicon esculentum Mill.) cultivars UGA-1113MT, tolerant to metribuzin, H-7492 (Heinz-7492), susceptible to metribuzin treatments, and the F1 cross of the two cultivars was determined.

Alginate controlled release formulations of metribuzin

Journal of Controlled Release, 1991
Abstract The release rates of metribuzin from various alginate-clay formulations were investigated. The standard formulation consisted of 1% alginate-1% metribuzin ≅ 10% clay and 88% water. The type of alginate was found to have little effect on release rate but did affect the physical properties of both the slurry and the dried beads.

Retention of Metribuzin by Sugarcane Residue

Soil Science, 2011
Assessment of herbicide retention in the soil environment is essential for minimizing their potential contamination of surface and groundwater resources. In this study, metribuzin retention characteristics by sugarcane mulch residue were quantified. Batch methods were used to quantify adsorption and desorption of metribuzin by the residue over a wide ...
