“…Should the polar-apolar balance be sufficiently extreme to inhibit either one of these processes excessively, the overall desired activity may not be achieved. The relationships of these and other molecular characteristics, as they relate to absorption of various organic substances, have been discussed by HARTLEY (1966), HOSKINS (1962), and in several of the previouslymentioned reviews. LINSER (1964) also emphasizes the importance of these characteristics in his treatise on the design of effective herbicides.…”

“…Treating the leaf as well as all interior non-leaf surfaces of a mite cage will provide continuous exposure to residue during the test. However, toxicity estimates obtained in this way may not be indicative of the toxicity of foliar residue, since the residual toxicity of a compound may vary with the substrate (Hoskins, 1962). The non-leaf surface inside the DLD mite cage was kept to a minimum, and did not exceed 2.8 and 7.4% of the available area in tests with fenpropathrin and fenbutatin oxide, respectively (2.8% for ventilation screen and plastic post; an additional 4.6% for inside rim of flat plastic ring).…”

Riedl, H. and Shearer, P.W., 1991. Double-leaf-disk residue assay for assessing the toxicity of repellent acaricides to spider mites (Acari: Tetranychidae). Exp. Appl. Acarol., A closed double-leaf-disk (DLD) assay is presented which prevents escape (runoff) of spider mites and exposes them to treated leaf tissue during the entire test period. The physiological (direct) toxicity of acaricide residue can be estimated with this assay without the interference of behavioral factors. In contrast, runoff is often a major component of the total mortality in open single-leaf-disk (SLD) assays, in addition to direct mortality. Fenpropathrin, a highly repellent pyrethroid acaricide, caused primarily runoff and little direct mortality in SLD assays with Panonychus ulmi (Koch). When runoff and direct mortality were combined, concentration-response lines and LCso values were identical to those obtained with the closed DLD assay. Assays with the organotin fenbutatin oxide gave si milar results, suggesting that the runoff response should be included when estimating the residual toxicity of these compounds with the standard SLD assay. In fact, excluding runoff mortality from the analysis may underestimate the toxicity of foliar residue. Providing residue-free non-leaf surface inside the DLD cage caused a shift to the right of the concentration-response line, resulting in higher Lcs0s. The DLD assay can be employed for mite species which are difficult to confine, and in toxicological studies of repellent or irritating acaricides. This assay may be particularly useful for elucidating the relationship between physiological toxicity and mite behavior in response to acaricide residue.

Este trabalho teve como objetivo avaliar a eficiência dos diferentes volumes de calda --340, 450, 1.000, 1.350 L/ha -- em duas concentrações de óleo mineral (OM) + cianamida hidrogenada (CH) -- 30+3 e 50+5 L/ha, respectivamente -- em macieira da cultivar Gala. Os resultados mostraram que nos anos com, pelo menos, 800 unidades de frio, todos os volumes e concentrações foram eficientes, exceto o de 340 L/ha, na concentração de 30+3 L/ha de OM+CH. Nos anos com menos de 800 unidades de frio, os melhores resultados foram com a concentração de 50+5 L/ha de OM+CH, em todos os volumes testados.
