Coating composition for protecting tree and wood and for controlling plant disease and insect pest

摘要

The present invention relates to 100 parts by weight of the aged ginkgo juice, 10 to 30 parts by weight of the yeast fermented product of the flesh layer of ginkgo berries, ginkgo leaves and ginkgo bark; 10 to 30 parts by weight of wood vinegar; and 5 to 25 parts by weight of titanium dioxide powder as a coating composition for protection of trees and wood and pest control, The aged ginkgo extract is prepared by placing ginkgo in a hot-pressurized extractor, purifying the hot water solution obtained by boiling at 110 to 250 ° C. for 60 to 72 hours, then distilling and cooling the ginkgo extract; And the prepared ginkgo extract is aged at 20 to 25 ℃ for 3 to 6 months to prepare the aged ginkgo extract; will be prepared by a manufacturing method comprising; The yeast fermented product of the flesh layer of the ginkgo biloba, ginkgo leaves and ginkgo bark is obtained by collecting the flesh layer of the ginkgo berry, raw ginkgo leaves and ginkgo bark from the ginkgo tree, steaming and drying the ginkgo berry flesh layer, ginkgo leaves and ginkgo biloba. pretreatment of the peel; After mixing 1 to 5 times the weight of water with the pre-treated ginkgo meat layer, ginkgo leaves and ginkgo bark, it is heated at 110 to 180 ° C for 1 to 3 hours to extract the ginkgo meat layer, ginkgo leaves and ginkgo biloba. skin extract preparation step; Inoculating yeast mold in a liquid medium in which bran and glucose solution are mixed with the flesh layer of the ginkgo berry, ginkgo leaf and ginkgo bark extract, and culturing at 25 to 35° C. for 5 to 10 days; And after mixing a sodium phosphate buffer solution with a culture containing the extract of the flesh layer of ginkgo biloba, ginkgo leaves and ginkgo bark extract, filtration and centrifugation to obtain a supernatant, so that the yeast fermentation of the flesh layer of ginkgo biloba, ginkgo leaves and ginkgo bark By using what is prepared by a manufacturing method comprising; preparing water; Prevents damage to trees due to climate disasters, restores scars on trees, and helps the growth of trees, as well as protecting trees and trees from pests and diseases It relates to a coating composition.
