Application of a mustard root bioassy to assess phytotoxicity of Group 2 herbicides
Group 2 herbicides exhibit high bioactivity at low concentrations in soil and may persist into the next growing season causing crop injury. A bioassay that is suitable for the detection of a range of Group 2 herbicides was ...
Effect of soil pH on sulfentrazone phytotoxicity
Factors affecting the phytotoxicity and persistence of Group 2 herbicides in prairie soils
Advantages of Group 2 herbicides include low use rates, broad spectrum weed control and low mammalian toxicity. However,Group 2 herbicides often persist in soil and cause damage to subsequent crops in rotation. Phytotoxicity ...
Mobility of flucarbazone in two prairie soils
Determination of 2,4-d amine in soils using anion-exchange membranes
A new method for the quantitative determination of 2,4-D in soils by use of anion-exchange membranes with GC detection was developed. Preliminary investigation of ion-exchange properties of pure 2,4-D acid on the membranes ...
