Description
Technical field
The invention belongs to technical field of pesticide preparations, be specially agricultural chemicals and pesticidal applications thereof containing plants essential oil.
Background technology
The agricultural product loss causing due to agricultural pest reaches 15-25% every year, use on a large scale chemical pesticide to there is certain positive role for stablizing farm output, but, because the insecticidal spectrum of chemical pesticide is wide, the field longevity of residure is longer, easily bring out insect it is developed immunity to drugs, the particularly pollution of chemical pesticide to agricultural product and environment, causes that women miscarries, baby's distortion and bring out the various diseases such as human cancer.Therefore, use biopesticide pest control to be more and more subject to people's attention.Along with the enhancing of human environment protection consciousness, the biopesticide of high-efficiency low-toxicity has become the developing direction of current agricultural chemicals.Biopesticide has mode of action uniqueness, and controlling object is single-minded, and to beneficial organism safety such as natural enemies, consumption is little, and degraded is fast, dangerous low to people, animal, ambient wind, is applicable to the features such as disease, worm, crop smothering integrated control.1992, world environments once explicitly pointed out with development conference, to control in the world sale and the use of chemical pesticide by 2000, the consumption of biopesticide reaches 60%, but, biopesticide only accounts for 2% the market share in global agricultural chemicals total sales volume at present, differs greatly with re-set target.Therefore, greatly develop biopesticide and become the significant task of countries in the world facing.Relevant department of China proposes 2015, requires the use of biopesticide to account for the 30-50% of agricultural chemicals total amount, and 12% left and right that area accounts for agricultural chemicals and always applies area is applied in 10% left and right that China's biopesticide annual production only accounts for agricultural chemicals gross yield at present.Visible development biopesticide has become one of China's significant problem anxious to be resolved.
China has mite class approximately more than 500 to plant, and endangers larger more than 40 kinds that have, and is mainly spider mite kind, goitre mite class, the crops such as main harm fruit tree, cotton, wheat class, vegetables, tobacco and tea tree, and being wherein subject to harm is the most seriously mandarin tree, apple tree and cotton.To the harmful mite class of agricultural have that volume is little, breeding is fast, strong adaptability and the feature such as easily develop immunity to drugs, be one of pest communities of the most difficult control of generally acknowledging.Miticide kind accounts for 10% left and right of insecticide sum at present.Expect 2010, Lepidoptera, nematode, mite, aphid and springtail are still the insects of main control, will account for the more than 60% of the whole insecticide market share for the insecticide of preventing and treating above 5 class pests.The mite evil of China occurs the most serious with fruit tree.Wherein the most seriously will count mandarin tree, be secondly apple tree, and field crop is mainly cotton.At present external pesticide development is very fast, and because China is large agricultural country, the good China market of external agricultural chemicals company, squeezes into China market by its product one after another.From the miticide of current use, although great majority are compounds efficient, low toxicity, also more easily decompose, most products is never poison, and mammiferous toxicity be can not be ignored, and environment is also had to certain influence, mite easily develops immunity to drugs simultaneously.In the long run, acaricidal development Ying Xiangfei killing livestock property noval chemical compound and biotype compound future development, reduce the toxicity to animal, alleviate the pollution to environment, solve the pesticide resistance problem of mite, therefore developing efficient, long-acting, wide spectrum, environmental pollution few, little to natural enemy injury, to each life stage of evil mite all effectively and be difficult for producing the novel miticide of safety of resistance, is also the task of top priority.
Plants essential oil is the very important natural perfume material of a class, and what the physical methods such as general employing distillation, squeezing, extraction (lixiviate) or absorption extracted from flower, grass, leaf, branch, skin, root, stem, fruit, seed or the secretion of fragrant plant has certain fragrance and volatile oily mater.The contained chemical composition more complicated of plants essential oil, can be divided into aliphatic, aromatic series and terpene three major types compound and their containing oxygen derivative by the difference of its chemical constitution.Plants essential oil content has Cupressaceae, Magnoliaceae, Lauraceae, Carrot family, Labiatae, composite family, Rutaceae, Zingiber, Myrtaceae, Dipterocarpaceae and grass family etc. compared with the plant of horn of plenty.Plants essential oil is a class natural vegetal feed additives, has painted, anti-inflammation, the effect such as anticorrosion, anti-oxidant, antitumor, can correct the peculiar smell of food, gives fragrance.Therefore, plants essential oil is widely used in the food manufacturing industries such as meat products, fruit and vegetable product, dairy products, aquatic products, baked goods.Plants essential oil is also the important source material of medicine, spices and chemical industry, is also conventional food additives, has antibacterial, anti-oxidant, anti-inflammatory, shortly oozes, desinsection mosquito repellent and the effect such as anticorrosion.But, so far, plants essential oil is also seldom seen to the purposes such as rarely seen fresh-keeping and storage that is used for grain for stifling sterilization expelling parasite for the document announcement of pesticide research.
