A Simplified Method for Determining Phytotoxicity, Leaching, and Adsorption of Herbicides in Soils

Pesticide Mobility: Determination by Soil Thin-Layer Chromatography

“…Furthermore, i). the ranking of mobility in Table 1 cor-, the auto-responds well to a consensus of the Le diffusion mobility literature (9,12,13 …”

Effects of Herbicides of Different Modes of Action on Leaf-Cell Membrane Permeability in Phaseolus Vulgaris

“…(Anderson et al 1962) and to ammonia resulting in ammonia toxicity (Sistrunk 1969 (Eshel and Warren 1967) and its lack of effect on leaf-cell membrane permeability in the present study was therefore expected.…”

Single Pesticide Volume: The Triazine Herbicides

“…The triazines ametryne and pro metryne (HOROWITZ 1968, RODGERS andWILCOX 1965), atrazine (IvEY and ANDREWS 1965), GS-14260 (HOROWITZ 1968), and simazine , IVEY and ANDREWS 1965 all exhibited this effect, as did amiben, CIPC, 2,4-D (ESHEL and WARREN 1967), DCPA (IvEY and ANDREWS 1965), diphenamid (DUBEY and FREEMAN 1965), diuron (DAWSON et al 1968, IvEY andANDREWS 1965), linuron (DUBEY and FREEMAN 1965), monuron , and trifluralin (ESHEL and WARREN 1967). Little simazine, applied at 1.5 kg./ha., appeared below ten cm.…”

“…HELLING The pesticide in the columns described above was usually analyzed as that remaining in various sections of the column. In other cases, especially with mobile pesticides or when using relatively non-absorbent media such as glass beads, direct analysis is made of the column effluent (DAVIDSON and SANTELMANN 1968, ELRICK and MACLEAN 1966, ESHEL and WARREN 1967, RODGERS 1968. A simple example permitting this was the use of a Buchner funnel as the soil column (SMITH et al 1957).…”
