Long-acting organic pesticide for preventing and controlling violet root rot of codonopsis pilosula

Abstract

The invention discloses long-acting organic pesticide for preventing and controlling violet root rot of codonopsis pilosula and belongs to the field of pesticide. The long-acting organic pesticide forpreventing and controlling the violet root rot of the codonopsis pilosula is prepared from the following raw materials in parts by weight: 25 to 30 parts of castor stalks, 15 to 20 parts of soybean straws, 50 to 60 parts of ginkgo, 20 to 30 parts of petroleum ether, 20 to 25 parts of ethanol, 10 to 15 parts of lemon eucalyptus leaves, 5 to 10 parts of quercus robur leaves, 10 to 20 parts of prunus persica flowers, 5 to 7 parts of juniperus chinensis leaves, 0.1 to 0.5 part of fucose ester, 0.5 to 2 parts of mushroom type proteoglycan, 1 to 3 parts of sodium lauryl sulfate, 8 to 10 parts of rumex japonicus meisn, 20 to 30 parts of softened water and 7 to 8 parts of distilled water. The long-acting organic pesticide disclosed by the invention has a good effect of preventing and controllingthe violet root rot of the codonopsis pilosula and also can be used for promoting growth and development of the codonopsis pilosula and improving soil; the long-acting organic pesticide can be used for preventing and controlling diseases and also can be used for inhibiting insect damages to a certain extent.

Description

technical field

[0001] The invention relates to the field of pesticides, in particular to a long-acting organic pesticide and a preparation method thereof for preventing and treating Codonopsis pilosula purple spot feather disease. Background technique

[0002] Suhua Codonopsis, also known as Xidang, Platycodonaceae, Codonopsis genus, is distributed in the northwest of Sichuan, Qinghai, Gansu and southern Shaanxi to the middle of Shanxi in mainland China. The whole variety is nearly smooth and glabrous; the calyx lobes are smaller, about 10 mm long, and the upper or apex of the leaves are often sparsely pilose and ciliate especially when they are young. Suhua Codonopsis has strong adaptability, likes mild and cool climates, is afraid of heat and waterlogging, and is more cold-tolerant. It is suitable for deep and loose soil, well-drained, and humus-rich sandy soil, but it is not easy to cultivate in viscous soil, saline-alkali land, and waterlogged land.
