Temporal and Quantitative Analyses of Stem Lesion Development and Foliar Disease Progression of Peach Rust in California [PDF]

open access: yesPhytopathology®, 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 ...

Potassium, calcium and copper phosphite to control peach rust and brown rot [PDF]

open access: yesIdesia (Arica), 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'.
