Abstract
The invention relates to a special natural bactericidal protectant for garden plants, which is characterized by containing 70-90 parts of dry plant powder (by weight), 2-6 parts of inorganic alkali and 5-10 parts of powdered surfactant; and the three ingredients are mixed to form the protectant. The protectant is convenient to transport and store, and is safe to use, particularly suitable for bactericidal and disease-resistant purposes of the garden plants with a higher requirement on the safety; the control effect on diseases such as damping off, powdery mildew, black leaf mold, brown spot, black spot, grey speck disease, infected anthracnose, gray mold, root rot, stem rot, leaf spot, leaf curl, fusarium wilt and nematode disease of the garden plants is good. The garden plants not only are appropriate for woody and herbaceous flower, leaf or fruit ornamentals, but also for shelter plants and economic plants in gardens, green fields and scenic resorts, as well as the plants and garden seedlings for indoor flower decoration.
Description
Technical field
The invention belongs to prevention and the administrative skill field of Ornamental Diseases, be specifically related to a kind of natural bactericidal agent and uses thereof and compound method of ornamental plant special use.
Background technology
Before chemical synthetic pesticide emerges, many countries natural agricultural chemicals of development and application in a large number just in the world.Since the forties in 20th century, chemical pesticide because it is wide in variety, instant effect, easy to use, lower-price characteristic dominate in pesticide market, cause the research of botanical pesticide being once absorbed in low ebb.But shortcoming and long-term unreasonable use due to chemical pesticide itself, expose gradually some serious problems, as damage by disease and insect produces resistance, residue of pesticide and the damage by disease and insect causing due to killed natural enemies are rampant again, be 3R phenomenon (Resistance, Resurgence, Residue), bring hidden danger to people's health.People generally believe that the agricultural chemicals of 21 century should be " the harmonious agricultural chemicals of environment " or " biorational agricultural chemicals "; Be necessary development " environment friendly agricultural " and " environment friendly agricultural preparation ".Develop in recent years low toxicity, low-residual, the natural bactericidal agent little to environmental influence, become gradually the focus of control of plant disease, and the plant huge resource that is occurring in nature is found, developed new reactive compound or new lead compound from plant corpus, cause especially the concern of countries in the world.
Plant is the natural treasure-house of bioactive compound, the secondary metabolite of its generation surpasses 400,000 kinds, and wherein most of chemical substances all has desinsection and antibacterial activity as terpenes, alkaloid, flavonoids, steroidal, phenols, unique amino acid and polysaccharide etc.Wilkins and Board once reported and had 1389 Plants likely as bactericide in 1989, wherein comprised many dissimilar compounds.At present people have extracted the active substance of antimycotic, bacterium, virus, nematode, desinsection, weeding from plant, microorganism.Initiative novel agrochemical has number of ways, as experience screening, analogize synthetic, natural products model and biorational design etc., wherein to natural products, to the research and development of botanical pesticide, is particularly the focus of current novel agrochemical initiative.
At present, because pesticide developing cost is more and more higher, the target of exploitation is mainly for cereal crops and economic crops, for ornamental plant, be the bactericide specially of protection target seldom specially, the protection of ornamental plant mainly or with reference to the medication of disinfectant use in agriculture is managed, yet, ornamental plant belongs to ornamental plants, the plant nearest with people, become the part that people beautify the living environment, if drug toxicity is too large or smell is more unpleasant, pollute human settlement, to people, can cause the health risk larger than agriculture medication, therefore for ornamental plant, be protection target, exploitation low toxicity, free from extraneous odour, the natural bactericidal agent of low-residual is very important, also meet the requirement of the more and more stronger security needs of people.
Modern bactericide, no matter be chemosynthesis or biogenic, be all to produce and become commodity with the form of pesticidal preparations in commodity manufacture process, is diluted with water in use finite concentration, spraying is used, and this preparation exists certain potential safety hazard when transportation, storage.
Summary of the invention
For the above-mentioned problems in the prior art, the object of the invention is to natural bactericidal agent and uses thereof and compound method that design proposes a kind of ornamental plant special use, be convenient to transportation, storage, use safety, be especially suitable for sterilization and antibacterial use to the higher family plant of security requirement.
For this reason, the present invention takes following technical scheme: a kind of natural disinfection protectant of ornamental plant special use, it is characterized in that being mixed by three kinds of compositions, and be respectively by weight: plant drymeal 70-90 part, inorganic base 2-6 part, powdery surface activating agent 5-10 part.
Described plant drymeal is with camplotheca acuminata, mappia foetida (having another name called pittosporum tobira false " Chailong " tree), the root of one or more plants such as foetid nothapodytes herb, Ophiorrhiza japonica, thunder godvine, Chinese yew, stem, leaf, fruit, in the situation of drying in the shade, are crushed to 300 orders and become above plant drymeal.
Inorganic base is NaOH or KOH.
Described powdery surface activating agent refers to neopelex or lauryl sodium sulfate.
The natural disinfection protectant of ornamental plant special use be mainly used in control object damping off, powdery mildew, black points, brown spot, black spot, graywall, zonate spot, dye anthracnose, gray mold, root rot, stem rot, leaf spot, leaf curl, fusarium wilt, nematodosis.
The plant that the plant of protection is afforestation, not only comprises that the sight of woody and draft is spent, sees leaf or fruit effect plant, and the securing plant and the economic plants that are applicable to gardens, greenery patches and scenic spot, also comprises the ornamental plant of indoor flower and gardens seedling.
When this natural disinfection protectant need be used, three kinds of compositions are mixed, with 50-200 warm water (30-50 ℃) doubly, stir, place 2-24 hour, be made into the agricultural chemicals with bactericidal activity.
The present invention take, there is camplotheca acuminata, mappia foetida (having another name called pittosporum tobira false " Chailong " tree), foetid nothapodytes herb, Ophiorrhiza japonica, the thunder godvine of bactericidal activity, the powder that dries in the shade of Chinese yew as base stock, add inorganic base NaOH or KOH, add again powdery surface activating agent neopelex or lauryl sodium sulfate, 3 kinds of compositions mix to pack according to certain ratio and form product, at this moment product itself is not also insecticide, and transportation and storage are very safe.While needing family to use, with 50-200 warm water (30-50 ℃) doubly, stir, placing 2-24 hour, at this moment just become the agricultural chemicals with insecticidal activity. the present invention is not only suitable for the ornamental plants such as flowers, potted landscape, seedling, lawn but also is adapted at viewing and admiring is upper use of family crops (ornamental crops) of major function.
