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.…”

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

“…Weidhass, Bowman & Schmidt (1961) found that after 24 h DDT adsorption into soil from aqueous dispersion was 80%, and parathion adsorption was 63%, both from a 100 ml volume. Hurtt et al (1958) found that CIPC penetrated to a greater depth in dry sandy loam than in moist sandy loam, but that the reverse was true in clay soil. Hadaway & Barlow (1963) showed that malathion, fenthion and U.C.…”

“…In laboratory leaching studies using soil columns, various methods have been used to assess the movement of compounds. The column may be sliced into sections (Anderson, Richards & Whitworth, 1968;Crafts, 1935;Horowitz, 1968Horowitz, , 1969aHurtt, Meade & Santelmann, 1958;Ogle & Warren, 1954;Sheets, 1959), may be made with a slot into which the test species can be sown (Lambert, Porter & Schiefer-stein, 1965;Talbert et at., 1971) or cut longitudinally (Neururer, 1972). Another approach is to collect and bioassay the leachate (Day et at., 1961;Eshel & Warren, 1967).…”

R^sum6: ZusammenfassungBioassay techniques used in herbicide studies are based on the response of chosen organisms, superior plants or microorganisms, to the chemical. Various means of assessment are used: germination, weight or size of plant parts, modifications in physiological activities such as photosynthesis and transpiration, and typical symptoms. Several special bioassays are described. Dose-response relations are affected by the age of the indicator plant and environmental conditions of growth. Results can be estimated visually or by objective measurements; for correct interpretation appropriate controls and standards must be included in each experiment. Examples are given of bioassay procedures developed to investigate various aspects of herbicide behaviour: soil effects, dissipation from the soil surface, movement in soil, degradation and persistence. Application de la technique des essats biologiques aux recherches sur les herbicides.Les techniques des essais biologiques utilis6s dans les 6tudes sur les herbicides sont bas6es sur la r6ponse au produit d'organismes choisis, plantes sup6rieures ou microorganismes. Des moyens varies d'6valuation sont utilises: germination, poids ou taille de parties de plantes, modifications dans les activit6s physiologiques telles que la photosynthdse et la transpiration, enfin symptomes typiques. Plusieurs essais biologiques sp6ciaux sont d6crits. Les relations entre la dose et la r6ponse sont affectees par I'age de la plante utilis6e comme indicateur, ainsi que par les conditions de l'environnement qui agissent sur la croissance. Les rdsultats peuvent etre estimfis visuellement ou par des mesures objectives pour une interpretation correcte, des t6moins et des r6f6rences appropri6s doivent etre inclus dans chaque experience. Des exemples sont donn6s de protocoles d'essais biologiques 6tablis pour 6tudier divers aspects du comportement des herbicides: influence du sol, dissipation depuis la surface du sol, mouvement dans le sol, degradation et persistance.
