Problems solved by technology

However, these control methods also have their obvious disadvantages, such as: agricultural control is time-consuming and labor-intensive, and the problem is more prominent in the current situation of young and strong laborers in rural areas; physical control can only control the population to a certain extent. Insect pests are difficult to completely avoid; biological control is costly and technically difficult, and the control effect is greatly affected by the environment; although chemical control is effective, it has large pollution residues and does not meet the requirements of organic production

Embodiment 1

[0088] Preparation of materials: Fresh leaves of masson pine, fresh fruits of Chili pepper, fresh stems and leaves of Tripterygium wilfordii, and human urine should all be selected from areas where soil, water, air and other environmental conditions are free from pollution, and where the growth environment has not used chemical fertilizers or chemical pesticides. No mining and other industrial pollution and heavy metal pollution. Otherwise, it will affect the quality of organic loquat. When preparing, first shake off the soil, water and other foreign matter on the fresh leaves of masson pine, fresh fruits of seven-star pepper, and fresh stems and leaves of Tripterygium wilfordii. Do not wash with water. If there is dew when harvesting, wait for the water to dry before proceeding Preparation: mash the fresh fruit of Chili pepper into irregular granules or lumps (the size is not strictly required), and cut the fresh leaves of Pinus massoniana and fresh stems and leaves of Tripte...

Abstract

The invention discloses an organic loquat botanical psyllid insecticide and a use method thereof. The botanical insecticide is prepared from fresh leaves of masson pine, fresh fruit of seven-star pepper, fresh stems and leaves of tripterygium wilfordii and human urine. The weight-to-mass ratio of the four components of masson pine fresh leaves, seven-star pepper fresh fruit, tripterygium wilfordii fresh stems and leaves, and human urine is 2.5 to 3.5:1.0 to 2.0:3.5 to 4.5:7.0 to 10.0, and the preferred ratio is 3.0:1.5:4.0 : 8.5, the four components are calculated by weight to mass ratio, wherein the fresh stems and leaves of Tripterygium wilfordii are auxiliary agents, and there is a synergistic effect between the preparations. The foam preparation has a remarkable killing effect on the organic loquat psyllid. This agent is diluted with water at a dose of 40-60kg.667m-2 1.0:2.0 and sprayed. The brewing preparation has stable dosage form, rich source of raw materials, convenient use in production, simple operation, low cost, no chemical pollution, and fully meets the requirements of organic loquat production.

Description

technical field [0001] The invention belongs to the development and application of new agricultural practical technologies, and relates to a method for the development, production and application of an organic loquat plant psyllid insecticide. Background technique [0002] Loquat [ Eriobotrya japonica (Thunb.) Lindl] is a plant of the family Rosaceae and the genus Loquat, native to southeast China. It is named for its leaves shaped like a lute, and its flowers can be used as medicine. Loquat is an evergreen small tree with a height of 3-5m and a maximum of about 10m; the leaves are large and long, thick and hairy, oblong, shaped like a lute, leathery, lanceolate, oblanceolate, Obovate or elliptic oblong, 12-30cm long, 3-9cm wide, apex acute or acuminate, base cuneate or attenuate into a petiole, upper margin sparsely serrated, base entire, bright, wrinkled above, densely grown below Gray-brown tomentose, 11-21 pairs of lateral veins; petiole short or almost sessile, 6-10m...
