| Abstract: Creeping bugleweed (Ajuga reptans L.) is a perennial ornamental commonly grown as a ground cover in temperate climates. Commercial samples of the A. reptans cultivars Royalty, var. Atropurpurea Bronze, Bronze Beauty, and Burgundy Glow showing mosaic and ringspot symptoms were tested for the presence of virus infection by direct antibody sandwich enzymelinked immunosorbent assay (ELISA) and viralassociated doublestranded (ds) RNA analysis. Cucumber mosaic cucumovirus (CMV) was detected by ELISA and dsRNA analysis in symptomatic samples of all cultivars tested. ELISA values were considered positive if the absorbance values were twice the negative control. Negative control values were established with asymptomatic tissue of the cv. Bronze Beauty. Tobacco streak ilarvirus (TSV) was detected only by ELISA in symptomatic samples of all cultivars except Royalty. No dsRNA suggestive of TSV was detected. Alfalfa mosaic virus (AMV) was detected by ELISA and dsRNA analysis in symptomatic samples of all cultivars tested except Royalty and var. Atropurpurea Bronze. dsRNA analysis also indicated the presence of a low molecular weight, possible satellite (sat) RNA associated with all symptomatic and asymptomatic Royalty and var. Atropurpurea Bronze plants tested. Northern (RNA) blot analysis with a digoxigeninlabeled fulllength clone of the (S) CARNA5 () CMV satRNA (ATCC no. 45124) confirmed that the low molecular weight RNA associated with the Royalty and var. Atropurpurea Bronze cultivars was indeed CMV satRNA. Only AMV has been previously reported in A. reptans in the United States (1). This is the first report of CMV and its satRNA, as well as TSV, in A. reptans in the United States. |

| Abstract: Eleven fungi are recorded in New Zealand for the first time: Cercospora nasturtii Pass. on Rorippa nasturtium-aquaticum (L.) Hayek; Frommeella tormentillae (Fuckel) Y.Hirats. on Potentilla anglica Laichard. x P. nepalensis Hook.; Microsphaera sp. on Magnolia quinquepeta (Buc'hoz) Dandy; Peronospora candida Fuckel on Anagallis arvensis L.; P. digitalidis Gaeum. on Digitalis purpurea L.; P. mesembryanthemi Verwoerd on Dorotheanthus bellidiformis (Burm.f.) N.E.Br.; Pseudocercospora nandinae (Nagat.) X.J.Liu et L.Y.Guo on Nandina domestica Thunb.; Puccinia conii Lagerh. on Conium maculatum L.; P. nakanishikii Dietel on Cymbopogon citratus (DC. ex Nees) Stapf.; Ramularia ajugae (Niessl) Sacc. on Ajuga reptans L.; and Stagonospora atriplicis (Westend.) Lind on Chenopodium album L. and C. murale L. A total of 125 new host/pathogen records are given for 65 other species. Included amongst these combinations are 28 rusts, 12 downy mildews, 5 powdery mildews, 5 smuts, 5 white rusts, rots caused by Botrytis and Sclerotinia, and many leaf spots and blotches. The hosts include introduced weeds, cultivated crop and horticultural plants, and indigenous plants. |

| Abstract: Experiments with Sitona humeralis adults and Pieris brassicae larvae prove that the Ajuga species possess considerable inhibitory effect on nutrition. In both cases we found that from leaves treated with Ajuga extracts the animals consumed small, if any quantities. This was established from the values of the consumption index. The relative growth rates and gross efficiencies calculated for the Pieris brassicae larvae showed that the consumption of most of the extract treated leaves not sufficient for the growth of the larvae, they lost weight, while in the control the larvae developed undisturbedly. On plants treated with Ajuga extracts a large proportion of the insects stay for a short time, according to observations they even leave the plant. With the Sitona humeralis adults all the 5 extracts gave similar results. In the case of Pieris brassicae larvae the best result was obtained with Ajuga reptans var. reptans extract (ARRBT33/i/MT/2) prepared at the time of flowering. From the results we have drawn the conclusion that the plant produces the largest amount of nutrition inhibiting substance of "highest efficiency" at the time of flowering, so in the course of further investigations it would be necessary to study the plants on flowering. It may be important to separate such substances of the plants, select the most efficient compound or compounds, and examine them for usability. Research work with the Ajuga species has left many questions unanswered, but we hope that the investigations will go and contribute to the realization of a "purer" plant protection. |

| Abstract: Plants of Swedish ivy (Plectranthus australis R. Br.) received by the Cornell University Plant Disease Diagnostic Laboratory from a Rochester, New York, commercial florist showed sunken necrotic ring spots and line patterns. Plants eventually recovered from these prominent symptoms, but new growth showed chlorosis, mostly confined to the margin of the leaves. The apparent causal agent was identified by immunodiffusion tests and diagnostic plant species (e.g., bean, cowpea, and pea) as alfalfa mosaic virus (AMV). In the greenhouse, Swedish ivy plants derived from cuttings of healthy plants were inoculated with isolates of AMV originally recovered from Swedish ivy, pea, Valerianella olitoria (L.) Poll., and Ajuga reptans L. All four isolates symptoms, consisting of very prominent local and systemic reddish brown sunken rings and oak leaf and linear patterns, accompanied by leaf malformation and plant stunting. |
