    Notes: In this article the authors report the results of small group discussions with some 415 first-line supervisors in the mining industry. The results are compared with those from a number of earlier studies of mining. Changes which have affected the supervisory position are described, and the role of behavioural research in industry is discussed in relation to both organizational analysis and to training.

    Notes: Summary. White ash (Fraxinus americana L.) trees, 2 years of age, treated continuously with 10 ppm picloram (4-amino-3,5,6-trichloropicolinic acid) in nutrient culture were only slightly injured after 4 weeks whereas red maple (Acer rubrum L.) trees were killed after only 2 weeks treatment.When the roots were exposed to 10 ppm 14C-picloram, the rate of root uptake, acropetal translocation in the stem, and accumulation in the leaves was much lower in the susceptible red maple than in the tolerant white ash. The foliar penetration and translocation of 14C-picloram applied to the leaves was very slight but similar in both species. Although a radiolabelled picloram metabolite was isolated from plant extracts, it was formed at equal rates in both species.It was concluded that the tolerance of white ash was not related to lower rates of picloram uptake or faster rates of picloram detoxication. It was postulated that the high susceptibility of red maple was due to a blockage of the xylem by picloram which caused death by a dessication of the leaves and upper stems.

    Notes: Summary. The efficacy of NN-diallyl-αα-dichloroacetamide (R-25788) as an antidote for reducing the injury of various herbicides in corn (Zea mays L.) was tested under controlled conditions in growth rooms. The application of R-25788 to the soil as a pre-plant incorporated treatment to corn significantly reduced the toxicity often out of twenty-two herbicides tested. These ten herbicides were, in order of decreasing effectiveness of the antidote, EPTC, barban, sulfallate, vernolate, molinate, butylate, alachlor, pebulate, linuron and di-allate. In quartz sand nutrient culture, R-25788 was more effective as an antidote for barban applied to the foliage of corn than it was for barban applied to the roots.
