The invention discloses a plant source pesticide for efficiently preventing and controlling main golden autumn pear diseases and insect pests (psylla chinensis, pear yellow meal aphid, schizaphis piricola, fruit piercing moth and pear black spot). The plant source pesticide is mainly prepared from ginkgo leaf, stem and leaf of tung tree, oleander leaf, arborvitae leaf, Chinese red pine leaf, litsea cubeba fruit, tea-oil tree residue cake, marigold root and sabina vulgaris leaf by extracting and processing. Meanwhile, the invention discloses a preparation method and application of the plant source pesticide, and belongs to the technical field of plant protection. The plant source pesticide can efficiently prevent and control the main golden autumn pear diseases and insect pests such as psylla chinensis, pear yellow meal aphid, schizaphis piricola, fruit piercing moth and the like, can effectively inhibit the growth of pathogenic bacteria of the pear black spot of the golden autumn pears at the same time, and has good environmental safety and good development and application prospects.
Description
Technical field
The invention belongs to the plant protection field, relate in particular to botanical pesticide and preparation and the application of a kind of pear sucker of preventing and treating Jing-Qiu Pear, eliminating pear aphid, pears Schizaphis spp, fruit piercing moth, Pear black spot.
Background technology
Jing-Qiu Pear is early 1990s, meticulously selects a kind of high yield and high quality pears class new varieties by the Hunan Province scientific and technical personnel from Japanese new peak bud mutation kind, belongs to the Chinese pear system, because its maturing stage gained the name at the beginning of autumn late summer, by provincial authorization.It is large that Jing-Qiu Pear shows as fruit, and outward appearance is golden yellow, sparkling and crystal-clear bright, and meat is white, crisp, tender, thin, the juice multi-flavor is sweet, early bearing high yield, best in quality, than characteristics such as storage tolerances, " southern pears king " laudatory title being arranged, have higher economic worth, is the more rising kind in south.Jing-Qiu Pear now has been generalized to 8 provinces (district) such as Hunan, Guizhou Province, river, osmanthus, Fujian, Zhejiang, Jiangxi, Henan after passing through relevant expert's evaluation in 1994, and its cultivated area has surpassed 50,000 mh at present
2, annual production reaches more than 10 remaining tons.Along with cultivated area constantly increases, all kinds of extermination of disease and insect pest work also seem particularly important.
Because Jing-Qiu Pear blade cuticula is thinner, be subject to damage by disease and insect harm, had a strong impact on output and the quality of Jing-Qiu Pear.Main pest species on the Jing-Qiu Pear has pear sucker, eliminating pear aphid, pears Schizaphis spp, fruit piercing moth, Pear black spot etc. according to investigations.Mainly relying on chemical agent to prevent and treat aspect the Jing-Qiu Pear extermination of disease and insect pest at present, exist disorderly execute, the tendency of lavishment agricultural chemicals, chemical fertilizer, cause the Jing-Qiu Pear fruit unexcellent, more can not guarantee green, non-harmful fruit, cause the tremendous economic loss to the orchard worker, be unfavorable for the sustainable development of whole Jing-Qiu Pear industry.Therefore seek safety, low toxicity, biopesticide has become question of common concern in the current control Jing-Qiu Pear damage by disease and insect efficiently.Botanical pesticide has become one of focus of current exploitation, the nuisanceless novel biopesticide of development because of features such as it is efficient, low toxicity, low-residual, from plant, seek desinsection, Substance, its main advantage is: 1) floristics and One's name is legion, Environmental compatibility is good.Botanical pesticide has its smoothly degradation pathway at natural world, and environmental pollution is little; 2) biologically active is various.Plant has not only been synthesized the base substance that sustains life, and has synthesized also that chemical constitution simplified and traditionally differs, miscellaneous killing pests and suppressing bacteria active substance, and its mode of action is various; 3) to higher mammal and pest natural enemy safety.The action of contace poison of most plants source pesticide is not strong, on the pest natural enemy impact seldom; 4) pest is difficult for developing immunity to drugs.Botanical pesticide often contains several active ingredients, and mechanism of action is different from general chemical pesticide, is difficult for making pest to develop immunity to drugs; 5) to farm-forestry crop safety, and the botanical pesticide that has can also induce farm-forestry crop to produce resistant effect.
Summary of the invention
The objective of the invention is the blank for prior art, the botanical pesticide and compound method and the application that provide a kind of high-efficiency prevention and control to comprise the Jing-Qiu Pear main diseases insect pests such as pear sucker, eliminating pear aphid, pears Schizaphis spp, fruit piercing moth, Pear black spot, significant to the non-environmental pollution control of Jing-Qiu Pear main diseases insect pest.
The objective of the invention is to realize in the following manner:
A kind of botanical pesticide of preventing and treating the Jing-Qiu Pear damage by disease and insect, made by the composition of following percentage by weight:
