The invention belongs to the technical field of agriculture, relates to a disease and pest preparation for day lily, and particularly relates to a high-resistance day lily disease and pest preparation and a preparation method thereof.

Background

Daylily, also called day lily, forgetmenot-sorrel and brain-strengthening herb, is a perennial root herbaceous plant of hemerocallis of Liliaceae. The edible part is bud which contains abundant nutrients necessary for human body such as sugar, protein, vitamin C, calcium, fat, carotene, amino acid and the like, and the nutritive value of the bud is very high. The daylily has sweet and cool nature and taste, and also has the effects of stopping bleeding, diminishing inflammation, clearing heat, promoting diuresis, helping digestion, improving eyesight, soothing the nerves, strengthening the brain, resisting aging and the like. In addition, researches show that the day lily also has various health-care functions of reducing blood fat, reducing blood pressure, resisting cancer and the like. As can be seen, the day lily is a flower rare vegetable with extremely high nutritive value and multiple health care functions.

However, with the serious land impoverishment and the unsophisticated and systematic planting of the day lily by growers, the growth period of the day lily of the plant is long and the yield is low in the traditional method, the whole growth period of the day lily is damaged by various plant diseases and insect pests, and if the control is unfavorable, the yield is extremely reduced. Therefore, the comprehensive prevention and control of the disease, insect and weed of the daylily are very important.
