Abstract
The invention provides a plant based natural bactericide for pepper Cladosporium grease (leaf) mold. Raw materials of the bactericide comprise garlic essential oil, plant essential oil mixture, organic solvent, surfactant and water; wherein, the garlic essential oil is used as a main bactericide component. The bactericide comprises more than two other plant essential oils which are used as synergistic agent to improve the efficiency of killing the pepper Cladosporium grease (leaf) mold. According to the invention, different chemical components of the plant essential oils are combined, therefore, the aim to control the pepper Cladosporium grease (leaf) mold can still be achieved under the condition of lower consumption, and the possibility of resistance to a single or several chemical compounds can be prevented. The bactericide has complex chemical components and several types of chemical functional groups, therefore, the acting efficiency is improved, more synergy modes are achieved, the permeability of the chemical components is improved and the persistent of the bactericide for the crops is prolonged. The chemical components of the bactericide are originated from natural medicinal plants, thus being harmless to persons and animals and safe to the environment.
Description
Technical field
The invention belongs to the bactericide field, be specifically related to a kind of vegetable source natural bactericide that is used for the capsicum sooty mold, contain galic essential oil, plants essential oil mixture, organic solvent, surfactant, water in the raw material of described bactericide; This bactericide is nontoxic to people and animals, and is environmentally safe.
Background technology
At present, the annual expense with the pest control with insecticide agent to preventing and controlling pest in the whole world is up to 10,000,000,000 dollars, and even so, the loss that annual insect pest causes still accounts for 20-30 % of total output of crops.Yet, because the long-term chemical pesticide that uses brings environmental pollution and person poultry poisoning, a series of problems such as sick worm pesticide resistance raising, some countries have begun chemical pesticide is taked to limit the use of and the forbidding measure.Particularly 1992, world environments proposed " sales volume of inner control chemical pesticide and use in the world, the output of biopesticide in 2000 should account for 60 % of agricultural chemicals total amount " afterwards with the development conference, and each state has all strengthened the development and the exploitation of biopesticide.
The research and development of pure natural plant source pesticide becomes the emphasis and the focus of various countries, the world today gradually.Since the seventies in 20th century, countries in the world government has begun to pay attention to research, development and application safety, harmless, efficient, multi-functional botanical pesticide.According to bibliographical information: the countries in the world scientist studies desinsection, mildew-resistant, weeding and the growth promotion bioactive ingredients of 2000 various plants, wherein is no lack of the traditional Chinese herbal medicine of being.These Chinese herbal medicines mainly comprise: Meliaceae (seal chinaberry, melia toosendan), composite family (Dalmatian chrysanthemum), pulse family (trifoliate jewelvine, Sophora alopecuroide), Ericaceae (Azalea pontica), Celastraceae (thunder godvine), Thymelaeceae (root of langdu), Labiatae (aldehydes matter), Lauraceae (camphor tree) etc.
So far, the portioned product listing has been arranged.Like Dutch Ropapharm B. V. I. O. with Orv oil and thyme wet goods vegetable oil through the composite preparation that obtains; Be used to kill plant pest and sanitary insect pest effect highly significants such as mosquito, fly; And this medicine be superior to the lindane be the basis chemical insecticide; Humans and animals is not had toxic and side effect, receive the welcome of countries in the world, in the registered use of China." sharp strength is special " botanical pesticide preparation of Germany's plant pesticide exploitation, the insect-piebald worm strong and crushing big to pesticide resistance in the vegetables has desirable control efficiency.
Botanical pesticide exploitation is is both at home and abroad mainly researched and developed from two innovation focuses:
The one, from traditional vegetable drug, extract desinsection, fungicidal activity position (composition), as host, be mixed with non-harmful agricultural chemicals.Studying many plants has: composite family, Meliaceae, Celastraceae, Ericaceae, Thymelaeceae and mineral humic acid etc.As proposing pyrethrins, from tobacco leaf, isolate nicotine, from the tuber of stemona, isolate stemonine etc. from composite family.At present, China is registered has with the botanical pesticide insecticide of producing: nicotine, galic essential oil, rotenone, pyrethrins, stemonine, chinaberry is plain, return artemisin, jervine, camptothecine and humic acid with and the about kind more than 30 of derivative;
The 2nd, from miscellaneous medicinal plant, isolate the active substance of desinsection, sterilization, process derivative, or carry out the chemical constitution transformation as template with insecticidal activity; Research through structure-activity relationship and insecticidal mechanism; Carry out bionical synthesizing, formulate out the agricultural chemicals of high-efficiency low-toxicity property, as from feverfew; Isolated pyrethrins; Become to have developed and produced more than 20 kind of pyrethroid through anti-intercrescence, be widely used in crops, forestry, flowers and domestic hygiene insect, play remarkable prevention effect.But abundant at China's resources of medicinal plant, the plant of sterilization and disinsection has kind more than 4000 approximately, and the exploitation botanical pesticide is had advantageous advantage.Therefore, have the high and low botanical biological pesticide of cost of efficient, have important social benefit and economic benefit in Research in China and exploitation.
The capsicum sooty mold is one of common disease of capsicum, and all there is generation each vegetable-growing area, and outdoor cropping, the cultivation of protection ground all can be fallen ill.Time morbidity rainy during the chili growth is serious.Morbidity seriously causes fruit ripen in advance, blade to do sth. in advance withered and yellow coming off often, influences yield of hot pepper.Due to the capsicum sooty mold is infected by fungi Deuteromycotina capsicum spot bud branch mould Cladosporium capsici (March et Stey.) Kovachersky.Germ survives the winter on sick leaf, soil and plant residue with mycelia and conidium, produces conidium next year, borrows wind and rain, aleyrodid its spread in china, causes just to infect and infect.High humidity, the many susceptible diseases of aleyrodid.Therefore, control capsicum sooty mold all has great influence for the quality of the output that improves capsicum, assurance capsicum.
But, the obvious problem below frequently seen plants source pesticide and chemical pesticide exist in market competition in the market: the one, drug effect is slow, and the drug effect phase is short, and fungi-proofing insecticide efficiency is low; The 2nd, production cost is high; The 3rd, not strong to the drug effect of capsicum sooty mold; These three effects limit the industrialized development of botanical pesticide, need to solve the efficient and long-acting problem of existing product in the production practices, and to person poultry harmless, the environment amenable vegetable source natural bactericide that is used for the capsicum sooty mold.
Summary of the invention
The present invention provides a kind of vegetable source natural bactericide that is used for the capsicum sooty mold, contains galic essential oil, plants essential oil mixture, organic solvent, surfactant, water in the raw material of described bactericide; Drug effect of the present invention is fast, the drug effect phase is long, kill capsicum sooty mold efficient height, and to person poultry harmless, environmentally friendly.
