Abstract A description is provided for Mycosphaerella linicola. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: On leaves, stems and penduncles of Linum usitatissimum, and Linum spp. DISEASE: Pasmo disease of flax GEOGRAPHICAL DISTRIBUTION: Widespread with host (CMI Map 18, ed. 5, 1977). TRANSMISSION: The fungus carries over on crop debris and other Linum spp. It is said to remain viable in soil for several years (60, 2047). Infested seeds on germination produce infected seedlings (5, 365; 25, 449). In New Zealand seedborne infection was said to be a minor factor and windborne infection was described (43, 1336; 49, 3316).

The persistent toxicity of films of pyrethrum in P31 oil may endure on suitable surfaces under warehouse conditions for much longer periods than hitherto supposed, but unexplained fluctuations in toxicity may occur.Within the range 0·8 per cent. to 1·3 per cent. total pyrethrins, the pyrethrum content appears to be only a minor factor in determining the persistent toxicity of such films.The nature of the surface sprayed is of great importance in determining the persistent toxicity of pyrethrum films in P31 oil, which is negligible on concrete and increases steadily through the following list of surfaces—brick, heavy hessian, light hessian, jute, cotton, and wood; the last-mentioned two being particularly good substrates.Residual deposits of DDT or “ Gammexane ” derived from kerosene sprays are of little use on concrete, but appear otherwise little affected by the nature of the surface treated; they give a uniform degree of persistent toxicity on the various surfaces listed.

Podosphaera Leucotricha

Abstract A description is provided for Podosphaera leucotricha. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: On Malus spp., chiefly on M. pumila (apple), peach (Prunus persica), quince (Cydonia ualgaris) and Photinia spp. also attacked (Hirata, 1966). Also reported on almond fruit (43, 2544). DISEASE: Powdery mildew of apple. GEOGRAPHICAL DISTRIBUTION: Africa (? Kenya, Rhodaia, South Africa, Tanzania); Asia (China, India, Israel, Japan, U.S.S.R.); Australia and New Zealand, Europe (widely distributed) North America (Canada and U.S.A.); South America (Argentina, Brazil, Chile, Colombia, Peru). (CMI map 118). TRANSMISSION: Overwinters on host as dormant mycdium in blossom buds. The role of deistothecia in overwintering is doubtful. Spread by wind-borne conidia (Anderson, 1956).

Abstract A description is provided for Acroconidiella tropaeoli. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: On Tropaeolum spp. DISEASE: Causes severe losses in nasturtium seed fields in coastal California. It produces a yellowing and death of the leaves after mid season and this reduces yield. The fungus occurs sometimes on stems and is present on seeds but is most abundant on leaves where it forms characteristic irregular or subcircular brownish or purple spots visible on both sides. These are up to 1 cm diam. or often larger through confluence, the centres later shrivel and the surrounding tissues may form a broad yellow margin. GEOGRAPHICAL DISTRIBUTION: Argentina, Australia, Ceylon, Ethiopia, Guatemala, Haiti, India, Jamaica, Kenya, Mauritius, New Guinea, New Zealand, Tanzania, Uganda, U.S.A. TRANSMISSION: The pathogen is borne internally and externally in up to 93% of commercial nasturtium 'seed', persisting for at least 3 years in the form of thick-walled mycelium in the pericarp and seed.
