    Notes: Abstract Large quadrupole moments of 1-phonon states of sperical nuclei are shown to follow in a simple and direct way from time-dependent HF equations using the self-consistent perturbation expansion. Whereas the first order describes harmonic quadrupole oscillations, anharmonic terms arise in second order. The scattering of quasiparticles by quasi-particle pairs, which is neglected in RPA calculations, but included in this paper, leads to a second order response of the system and is shown to produce a strong enhancement of the quadrupole moments. Explicit results are obtained with a pairing-plus-quadrupole interaction and discussed within a schematic two level model.

    Description / Table of Contents: Samenvatting Met behulp van een mixertechniek wordt aangetoond, dat na een begieting van de wortels van jonge meloenen met benomyl (75 mg actieve stof/pot van 450 ml) de infektie doorFusarium oxysporum f. sp.melonis in kunstmatig besmette aarde heel laag blijft. In geïnfekteerde planten veroorzaakt deze behandeling een sterke vermindering van de hoeveelheidFusarium in de stengel. Wanneer de planten behandeld worden juist voor zij de eerste symptomen aantonen, wordt gewoonlijk de ontwikkeling van de parasiet gestopt zodat de planten kunnen genezen. Het produkt blijft tenminste 10 weken actief in de grond.
    Notes: Abstract It is demonstrated that benomyl, applied as a soil drench, is highly efficient in reducing the quantity of mycelium in muskmelon plants infected byFusarium oxysporum f. sp.melonis. When treated before symptoms appear, plants are generally cured. The blending technique used for assessing fungal spread in the xylem vessels is particularly convenient for studying the action of a systemic fungicide in a plant with vascular wilt.
