“…Rhizoctonia solani and representatives of the Pythium genus (generally controlled by fungicides) also cause "damping off" in seedlings (Butin and Peredo, 1986). Phragmidium violaceum is a compulsory parasite on several Rubus species and causes rust (Oehrens and González, 1974).…”

Components of essential oils from the Chilean Monimiaceae, boldo (Peumus boldus Mol.), tepa (Laureliopsis philippiana (Looser) Schodde), and laurel (Laurelia sempervirens (Ruiz & Pav.) Tul.) were determined using Gas Chromatography-Mass Spectrometry (GCMS) and fungistatic activity of the essential oils was tested against Rhizoctonia solani Kühn (Donk), Pythium irregulare Buisman, Ceratocystis pilifera (Fr.) C. Moreau, Phragmidium violaceum (Schultz) G. Winter, and Fusarium oxysporum Schltdl. The essential oils of the Monimiaceae species shared some common components; all three had the 3-carene, α-phellandrene, and α-pinene terpenes. L. philippiana and L. sempervirens also had safrole.The main components were ascaridol in P. boldus oil, 3-carene in L. philippiana, and safrole in L. sempervirens. The essential oil from L. sempervirens showed the highest fungistatic activity with significant differences in dose as well as exposure. P. violaceum was the most sensitive strain and P. irregulare the most resistant of all the essential oils (P. boldus extract affected growth by only 19%). Therefore, essential oils from these three plants could be used to control the fungal strains studied.

S U M M A R YThe host specificity of the rust fungus Phragmidium violaceum, a potential biological control agent of European blackberry (Rubus fruticosus) was studied by inoculating a mixture of 15 isolates of the rust on 108 plants of importance to the Australasian region. A scale of infection types was developed based on the results of microscopic and macroscopic observations of the reaction of host and non-host plants to the rust. The results showed that P. violaceum has a limited host range in the genus Rubus. The rust was able to reproduce on 17 taxa of Rubus previously unrecorded as hosts, including Australasian species of Rubus subgenera Dalibarda and Lampobatus. All other taxa attacked were species of Rubus subgenus Eubatus and the majority were hybrid cultivars containing European blackberry species.

The potential for fungi to control 14 important weeds in New Zealand is reviewed. Information provided includes the fungi already known from these weeds in New Zealand, fungi recorded from the native ranges of the weeds, and past work on the control of these weeds using fungi, both in New Zealand and elsewhere. The 14 weeds are: Berberisspp.; Buddleja spp.; Calluna vulgaris; Carduus spp.; Cirsium arvense; Clematis vitalba; Cytisus scoparius; Hakeaspp.;Hieraciumpilosella; Rubusfruticosus agg.; Senecio jacobaea; Silybum marianum; Solanum mauritianum; and Ulex europaeus. It is concluded that of the 14 weeds, those best suited as targets for biological control using fungi may be Calluna vulgaris, Carduus spp., and Senecio jacobaea, using the classical approach to biological control, and Cirsium arvense, Clematis vitalba, and Cytisus scoparius, using the mycoherbicide approach. Hakea spp. may be suited to both approaches.
