Analysis of pesticides by the thin-layer chromatographic-enzyme inhibition technique. Part II,rt review of the development of the method, (2) principles of the technique, (3) merits and limitations, (4) materials and methods, and (5) application of the technique to pesticide residue and metabolism studies. Part II is intended to be a continuation of that review; therefore, the principles and

Pesticide interactions in higher plants,r feasible, growers or commercial applicators choose to apply combinations of chemicals for obvious economic reasons. The fewer trips across the field, the less the expenditure of labor and equipment. In addition, combinations of chemicals frequently improve the spectrum of plant pests that is contr

Producing fixed P in the soil up to the fixing threshold (or saturation) is referred to as “quenching.” The objective of this experiment was to determine the excess of phosphorus required to produce labile, plant-available P, and the conditions in stored bauxite overburdens w

Eugene E. Kenaga into peds or aggregates determines the size and shape of soil voids, or pores, and this greatly influences the movement of water and gases in soil. As a result, soil structure can have a substantial impact on plant growth and determines erosion rates. An experiment was conducted to determine the ef
