Potassium, calcium and copper phosphite to control peach rust and brown rot [PDF]
Idesia, 2012 The phosphites have been recommended as plant protectors and inducers of host resistance against diseases. Three phosphite formulations (copper, potassium and calcium) were evaluated to control peach rust (Tranzschelia discolor) and brown rot (Monilinia fructicola), in an orchard with two cultivars: 'Chimarrita' and 'BR-1'.

New Fungicides and Application Strategies Based on Inoculum and Precipitation for Managing Stone Fruit Rust on Peach in California [PDF]
Plant Disease, 2003 In greenhouse and field studies, rust on cling peach caused by Tranzschelia discolor was significantly reduced on leaves and fruit compared with that on controls by foliar applications of wettable sulfur, an agricultural oil, a substituted aromatic (e.g., chlorothalonil), as well as benzimidazole (e.g., benomyl, thiophanate-methyl), sterol ...

Temporal and Quantitative Analyses of Stem Lesion Development and Foliar Disease Progression of Peach Rust in California [PDF]
Phytopathology, 2004 The development of rust epidemics caused by Tranzschelia discolor on leaves and stems of cling peach was studied in California orchards. Sporulating stems lesions were only detected from late March until July in 1997 and 1998. When rust was present in the fall, the quadratic equation Y = -82.51 + 1.97JD - 0.01JD2 using Julian day (JD) described the ...

Reação de genótipos de pessegueiro à ferrugem-da-folha Peach genotypes reaction to leaf rust
Pesquisa Agropecuária Brasileira, 2010 O objetivo deste trabalho foi identificar fontes de resistência à ferrugem-da-folha em pessegueiro. Foram realizadas três avaliações de incidência e severidade de ferrugem-da-folha em 15/1, 14/2 e 24/3 de 2005, em 17 genótipos; em 23/2/2006, a severidade
