Embodiment Construction
[0009] This experiment is divided into invention group and control group, each group handles 50 strains. Invention group 1 and control group 1 are tests carried out at cineraria (5 to 7 true leaves of seedlings) that have not yet experienced symptoms, while invention group 2 and control group 2 are for those that have begun to appear white powdery mold layer Trials performed on cineraria.
[0010] Invention group 1: The following medicinal liquid is sprayed on cineraria (seedlings with 5 to 7 true leaves) that have not yet developed symptoms, and the spraying method is to spray once every other week.
[0011] Example 1: 500 times liquid of fenrustin (that is, 2.00 grams of fenrustin in 1 liter of water) and 600 times of liquid H 2 o 2 (i.e. 1.67ml of H in 1 liter of water 2 o 2 ) were mixed at a volume ratio of 3:1.
[0012] Example 2: 800 times liquid of fenrustin (that is, 1.25 grams of fenrustin in 1 liter of water) and 800 times of liquid H 2 o 2 (i.e. 1.25ml of H i...

Abstract
The invention belongs to the field of a flower culture method, particularly the field of a florists cineraria culture method. A method of controlling powdery mildew of a florists cineraria is characterized in that the method comprises the steps of mixing 500-800 times of triadimefon with 600-800 times of H2O2 in the volume ratio of 3:1; and spraying the mixture to the seedling without diseases or the florists cineraria with leaves suffering from powdery mildew. The method has the advantages that by using the method, the control of the powdery mildew of the florists cineraria reaches up to over 80%. Compared with the conventional method of only spraying one liquid medicine, the method has obvious synergistic effect, no harm and residue, high efficiency and stable efficacy.
Description
technical field [0001] The invention belongs to the field of flower cultivation methods; in particular, the field of cineraria cultivation methods. Background technique [0002] Cineraria (Senecio cruentus), Asteraceae, Senecio genus, perennial herb, plant height is generally 30-50cm, the whole plant is hairy. The leaves are heart-shaped oval, with stalks, dark green leaves, and white hairs on the back of the leaves. The flowers are red, pink, white, blue, purple and other colors, and the flowering period is from November to April of the following year. It likes a cool, ventilated, and humid environment, and requires loose, fertile, well-drained sandy soil rich in humus. Not cold-resistant, avoid hot and dry, rain, strong light and frost. [0003] Cineraria is most susceptible to powdery mildew, which is a widely spread fungal disease. Powdery mildew mostly damages leaves, branches, flower organs and young shoots. In the early stage of the disease, a white powdery mold l...
