“…The effect on initial root growth, however, is but one aspect of the herbicidal action of chlorpropham, and a ver>' close relationship between the test results and field behaviour would not be expected. There was, nevertheless, a fair degree of correlation between the results ofthe root elongation tests and the relative susceptibility ofthe different speeies to soil-applied sprays, a conclusion which substantiates that of Wiese & Dunham (1954).…”

“…Following the introduction of chlorpropham (Witman & Newton, 1951), it became apparent that with this herbicide also there was a wide range in the response of different dicotyledons. Wiese & Dunham (1954) conducted tests on primary r(x>t growth and found that fagopyrum esculentum was the most susceptible of the species tested, Linum usitatissimum was intermediate, while Beta vulgaris, Pisum sativum L. and Clycine max Merr. were more tolerant.…”

The concentration of chiorpropham required to reduce primary-root elongation by 50°o was determined for more than 180 species of dicotyledons in laboratory tests and was found to vary from 0-01 ppm to more than 10 ppm. With certain exceptions, species within a family responded similarly; the Polygonaceae and Caryophyllaceae were the most susceptible and the Compositac were the mo.st tolerant. There was a general correspondence l>etween the test results and the relative susceptibility of species in the field. Tests with dilTerent varieties of Brassica oleracea and Daucus carota showed no significant diflerences in varietal response. Tolerance comparee de qttelquts dicotyledones au chlorprophamResume.

Abgesehen von einigen Ausnahmen reagierten Arten innerhalb einer Familie ahnlich; die Polygonaceen und Caryophyllaceen waren am empfindlichsten, die Kompositen am widerstandsfahigsten. Es bestand eine allgcmeine Cbereinstimmung zwischen den Testcrgebnissen und der Empfindlichkeit der Arten im Feld. Tests mit verschiedenen Sorten von Brassica oleracea und Daucus carola zeigten keine signifikanten Untersehiede in ihrem Verhalten.

“…Ries (1953) directed attention lo the marked sensitivity of buckwheat {Fagopyrum esculenturn Moench) to chlorpropham, and found that as little as 0-02 ppm in solution gave appreciable inhibition of primary root growth. Wiese & Dunham (1954) and Danielson (1959) also found buckwheat to be the most sensitive of the species which they tested.…”

Summary. A method for the bioassay of chlorpropham in soil from field plots is described which involves the preparation of mixtures of treated soil with untreated soil and the determination of the dilution required to produce 50% inhibition of primary root growth in buckwheat (Fagopyrum esculentum Moench). Using this method, it was found that the period required for 90% disappearance of chlorpropham from a sandy foam ranged from 3 to 14 weeks, according to the prevailing temperature and soil moisture conditions. When applications of 1 and 2 lb/ac were compared, the percentages of chlorpropham remaining at any one time were similar. Dosage biologique du chlorpropham dans le sol

In laboratory tests with 115 species of dicotyledons, the concentration of pronamide in water for 50% inhibition of root elongation ranged from 0.03 to >8 parts/million. With certain exceptions, species within a family responded similarly. Polygonaceae and Caryophyllaceae were the most susceptible and Compositae the most tolerant, as they were also to chlorpropham. There was good correspondence between the test results and the relative susceptibility of species to pre‐emergence application in the field.
