Study of systemic insecticides: Location and amounts of residue in plant tissues determined with aid of radio-phosphorus tracers

open access: yesCalifornia Agriculture, 1954
The systemic insecticides – schradan – octamethyl pyrophosphoramide and demeton or Systox–O,O-diethyl O-ethyl-beta-mercaptoethyl thionphos-phate–and their derivatives have shown unusual promise for the control of mites and aphids and other sucking ...

Assessment of Phosphorus Limitation in an Oligotrophic Lake Using Radiophosphorus Uptake Kinetics [PDF]

open access: yes
We used 32P uptake kinetics as a means of assessing periods of P limitation to phytoplankton growth in an ultraoligotrophic lake. Tracer experiments, conducted biweekly and weekly in 1975 and 1976, respectively, yielded information regarding the ...

The direct measurement of ATP and adenine nucleotide pool turnover in microorganisms: a new method for environmental assessment of metabolism, energy flux and phosphorus dynamics [PDF]

open access: yes, 2017
A method has been devised which enables the direct measurement of ATP and adenine nucleotide pool turnover. The method is based upon the incorporation of 32PO4 into the α-, β-, γ-P positions of ATP.
