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.

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.

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.

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.

The application of leidinmycin compounds in inhibiting plant pathogenic fungi and preventing and treating plant diseases belongs to the technical field of pesticide fungicides. In order to screen leidinmycin compounds capable of being used for preventing and treating plant diseases caused by plant pathogenic fungi or plant pathogenic oomycetes, five kinds of leidinmycin compounds are used for inhibiting plant pathogenic fungi and preventing and treating plant diseases. The leidinmycin compounds have strong inhibitory effect on plant pathogenic fungi, including the growth of fungal hyphae in Sclerotinia, Rhizoctonia, Elsinoe, Botrytis and Alternaria and the growth of oomycete hyphae in Pythium, Peronospora and Pseudomonas. In addition, the leidinmycin compounds have good prevention and treatment effect on plant diseases caused by the above plant pathogenic fungi and plant pathogenic oomycetes, and have no toxic side effect on plants, and can be developed and applied as effective components of pesticides or plant pathogenic fungicides.

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.

The present invention relates to a Spinacia oleracea plant comprising a nucleic acid molecule which when homozygously present provides at least intermediate resistance to Peronospora effusa races Pe: 1, Pe: 2, Pe: 3, Pe: 4, Pe: 5, Pe: 6, Pe: 7, Pe: 8, Pe: 9, Pe: 10, Pe: 11, Pe: 12, Pe: 13, Pe: 14, Pe: 15, Pe: 16, Pe: 17, Pe: 18, Pe: 19 and Pe: 20, wherein said nucleic acid molecule comprises a gene which comprises a coding sequence according to SEQ ID NO: 1 and a gene which comprises a coding sequence according to SEQ ID NO: 2, or a gene which comprises a coding sequence having at least 95.0% sequence identity to SEQ ID NO: 7 and comprises an insertion of sequence motif GAAATA between nucleotides 1235 and 1236 of SEQ ID NO: 7 and a gene which comprises a coding sequence having at least 95.0% sequence identity to SEQ ID NO: 8 and lacks a sequence according to SEQ ID NO: 14, wherein the 95.0% sequence identity is over the part of SEQ ID NO: 8 without the lacking sequence, or genes comprising the corresponding genomic sequences or genes encoding a protein having an amino acid sequence according to SEQ ID NO: 3, and a gene encoding a protein having an amino acid sequence according to SEQ ID NO: 4, or genes encoding proteins showing 95% sequence identity thereto. The invention further relates to a plant carrying the nucleic acid molecule and to methods of selecting, producing and growing such plants.

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.
