Abstract

Cercospora disease of sub-clover. Fungicide control of cercospora disease on sub-clover. Aim: To determine the effectiveness of various times and rates of application of benomyl for control of Cercospora disease (Cercospora zebrina) in sub-clover cv. Esperance. Locality: Bibby Springs (83MO4). Fungicide control of cercospora disease on sub-clover. Aim: To determine the effectiveness of various fungicides for control of Cercospora disease (Cercospora zebrina) in sub-clover cv. Esperance. Locality: Bibby Springs (83M03). Role of seed contamination and infection in cercospora disease on sub-clover. Aim: To determine the role of Cercospora zebrina seed contamination and infection in spreading Cercospora disease of sub-clover. Locality: South Perth Plots (83PE10). Treatments Esperance (82MO5). Sub-clover root rot. Effects of sprayseed® on sub-clover root rot. Aim: To determine the effects that."sprayseeding" of an established pasture has upon subsequent root rot levels. Locality: Albany (83AL22); Scott River (83BU9). Sub-clover root rot. Apron 35w seed treatments for root rot control. Aim: To test the effectiveness of various rates of Apron 35W (Ridomil) seed treatment for control of sub-clover root. Locality: Albany (83AL20); Scott River (83BU7). Sub-clover root rot. Fungicide drenches for root rot control. Aim: To test the effectiveness of Ridomil and Benlate soil drenches for control of sub-clover root rot. Locality: Albany (83AL21); Scott River (83BU8). Rapeseed diseases. Fungicidal control of rapeseed damping-off. Aim: To investigate the possibility of using fungicides to control damping-off in rapeseed cv. Midas. Locality: Mt Barker Research Station (83MT13). Rapeseed diseases. Fungicide control of blackleg seedling infection. Aim: To test the effectiveness of fungicides for control of blackleg (Leptosphaeria maculans) seedling infection. Locality: Mt Barker Research Station (83MT14). Rapeseed diseases. Yield losses from and cultivar susceptibility to white rust. Aim: To determine the yield losses from and cultivar susceptibilities to white rust (Albugo candida) for a range of B. campestris rapeseed cultivars. Locality: Mt Barker Research Station (83MT15). Treatements: The fifteen cultivars used were: 78N03-2, 78N03-5, 78NO4-2, 78NO4-4, 78NO4-5, 78NO4-15, 78NO5-5, 4074-75, 4076-77, 4190-91, 6278-79, DRC-1, NSW Sel. 2, Jumbuck, Span. The trial was sown on June 21st. One half of the plots were sprayed with Ridomil MZ 5WP @ 2.5 kg/ha on August 25th, September 5th, September 20th, and September 30th. Rapeseed diseases. Yield losses from and cultivar susceptibility to white leaf spot. Aim: To determine the yield losses from and cultivar susceptibilities to white leaf spot (Pseudocercosporella capsellae) for a range of rapeseed lines. Locality: Mt Barker Research Station (83MT16).
