Peronospora is a genus of oomycetes that are obligate plant pathogens of many eudicots. Most species in this group produce a downy mildew disease, which can cause severe damage to many different cultivated crops, as well as wild and ornamental plants. There are 19 genera that produce downy mildew, and Peronospora has been placed alongside Pseudoperonospora in the group of downy mildews with coloured conidia. Peronospora has far more species than any other genus of the downy mildews. However, many species have been moved from this genus to be reclassified to other or new genera. Among these was the most famous Peronospora species, formerly known as Peronospora parasitica, and now known as Hyaloperonospora parasitica. Now, the Peronospora species of most importance is likely the Peronospora tabacina. Peronospora tabacina causes blue mold on tobacco plants and can severely reduce yields of this economically important crop to the point where it has been classified as a bioweapon.
Bactericidal composition containing fluxapyroxad and thiediazole copper
InactiveCN107771825ASynergistic effect is obviousDelay key drug resistanceBiocideFungicidesBacterial compositionPhytophthora sp.
The invention relates to a bactericidal composition containing fluxapyroxad and thiediazole copper. The bacterial composition is compounded from fluxapyroxad and thiediazole copper in a binary mode, wherein a mass ratio of fluxapyroxad to thiediazole copper is (1-50) to (50-1); a mass fraction of fluxapyroxad and thiediazole in the preparation is 1%-80%, and the rest of the preparation is auxiliary components which are allowed to use and are acceptable in a pesticide. A dosage form of the bactericidal composition is missible oil, a suspending agent, wettable powder, a water dispersible granule, emulsion in water, microemulsion, a granule and a micro-capsule. The bactericidal composition is mainly used for controlling plant gray mold, peronospora and phytophthora germs.

Coleus plant named ‘G21015’
A new and distinct cultivar of Coleus plant named ‘G21015’ is disclosed, characterized by a compact, densely branched plant habit forming a globose shape. Foliage is dark burgundy red in the central area, surrounded by a thick gold-green picotee edge and a fine dark burgundy red margin. Floral initiation begins in early October, or later at 41N latitude, under natural daylength. Foliage is strongly resistant to Coleus downy mildew (CDM), caused by Peronospora choii. No symptoms of CDM have been observed on new variety ‘G21015’ since its selection in 2021 in greenhouse, outdoor container, or outdoor in-ground trials. In those same trials, CDM-susceptible Coleus varieties were observed to suffer foliage losses due to CDM infection at rates from 25% to 100%. The new cultivar is a Coleus, typically produced as an outdoor ornamental plant or for garden or container uses.

Coleus plant named ‘G22026’
A new and distinct cultivar of Coleus plant named ‘G22026’ is disclosed, characterized by a compact, densely branched plant habit forming an ovate-globose shape. Foliage is bright golden green with a dark red center. Floral initiation begins in mid to late October, at 41N latitude, under natural daylength. Foliage is strongly resistant to Coleus downy mildew (CDM), caused by Peronospora choii. The new cultivar is a Coleus, typically produced as an outdoor ornamental plant or for garden or container uses.

Coleus plant named ‘G22023’
A new and distinct cultivar of Coleus plant named ‘G22023’ is disclosed, characterized by a compact, densely branched plant habit forming a globose shape. Foliage is dark red on the upper surface and dark violet on the under side. Floral initiation begins in mid to late September, or later at 41N latitude, under natural daylength. Foliage is moderately resistant to Coleus downy mildew (CDM), caused by Peronospora choii. The new cultivar is a Coleus, typically produced as an outdoor ornamental plant or for garden or container uses.

Coleus plant named ‘G22031’
A new and distinct cultivar of Coleus plant named ‘G22031’ is disclosed, characterized by a compact, densely branched plant habit forming an ovate-globose shape. Foliage has a bright pink central blotch radiating into a large dark violet blotch surrounded by bright a golden green picotee. Floral initiation begins in late October, or not at all, at 41N latitude, under natural daylength. Foliage is strongly resistant to Coleus downy mildew (CDM), caused by Peronospora choii. The new cultivar is a Coleus, typically produced as an outdoor ornamental plant or for garden or container uses.

Peronospora resistance in spinacia oleracea
PCT designated stageWO2026131860A1Microbiological testing/measurementPlant genotype modificationPeronosporaPeronospora verbenae
The present invention relates to an allele designated alpha-WOLF 31 which confers resistance to at least one Peronospora effusa race, wherein the protein encoded by said allele is a CC-NBS-LRR protein that comprises in its amino acid sequence: a) the motif "MAEIGYSVC" at its N-terminus; and b) the motif "KWMCLR"; and wherein the protein has an amino acid sequence that in order of increased preference has at least 97% sequence similarity to SEQ ID NO: 11. The allele when present in a spinach plant confers complete resistance to at least Peronospora effusa race Pe:1, Pe:2, Pe:4, Pe:5, Pe:6, Pe:7, Pe:10, Pe:12, Pe:13, Pe:14, Pe:15, Pe:16, Pe:18, Pe:19, and Pe:20.
