Description
Technical field
The present invention relates to vegetable seeds coating agent preparation technical fields, and in particular to a kind of Antiphytoviral seed coat agent and its
Using.
Background technique
Since the viroses of plant are many kinds of (more than frequent species 2000), prevention and treatment is extremely difficult, is known as " plant cancer "
Title, harm be only second to fungal disease, have resulted in extreme loss to agricultural production.According to statistics, the annual crops in the whole world because
Economic loss caused by this is up to 20,000,000,000 dollars, wherein only tobacco mosaic virus (TMV) (Tobacco mosaic virus, TMV) is annual
Caused by economic loss (the Bos L.100years of virology:from vitalism via that is more than 100,000,000 dollars
molecular biology to genetic engineering.Trends in microbiology,2000,8(2):82-
87).Plant virus chemical control is constantly subjected to very big concern, practical kind and few in anti-plant virus agent, and prevents and treats
Effect is poor, and generally below 60%, and once break out, there is no effectively preventing method, there is destructiveness to production estimation.
Virus passes through seed transmission, infection of nourishing and generating, juice friction infection, insect-borne infection, pollen transmission.Seed transmission
Early stage malicious source is provided with infection of nourishing and generating, causes the prevalence of virosis.Have now been found that 166 kinds of plant viruses by seed
It infects, viral seed-transmission rate general 1%~30%, but soybean diseased plant seed belt nepovirus rate nearly reaches 100%,
Muskmelon seeds band pumpkin mosaic virus rate up to 28%~94%, big (small) wheat seeds band hordeivirus rate up to 50%~
100%, potato band virus reaches 100%.And Seed transmission, long-distance communications are allocated and transported by seed, expand lesion constantly,
It can be seen that effective control Seed-borne Virus and infection of nourishing and generating can effectively control drug source system and long-distance communications.Exploitation has antiviral
It the seed of effect and nourishes and generates and infects inorganic agent and be of great significance.
Antiviral seed treatment can effectively transmission control drug source system and long-distance communications, the generation of the viroses of plant, lure simultaneously
Plant pair virus generation system resistance is led, to reach effectively control virosis outburst, effective protection crop health improves yield
Purpose.The demand of Antiphytoviral medicament and exploitation are constantly subjected to very big concern, it has been found that Antiphytoviral medicament it is main
Have: diazosulfide (BTH), tiadinil (TDL), 4- methyl-1,2,3- thiadiazoles -5- formic acid (TDLA), DL- beta-amino fourth
Sour (BABA), virazole, Ningnanmycin, phenanthroindolizididerivative pyridine alkaloid antofine, connection triazole class compounds XY-13 and XY-
30, virus A (effective component is moroxydine hydrochloride and copper acetate), salicylic acid, polyhydroxy double naphthaldehydes, amino-oligosaccharide (chitin
Oligosaccharides, scientific name are β-Isosorbide-5-Nitrae-oligoglucoses amine).These products are mainly used for foliar control, because it prevents and treats mechanism or physics and chemistry
The factors such as matter limit their effective applications in seed treatment.
Trans-ferulaic acid (ferulic acid (FA), chemical name are 4-Hydroxy-3-methoxybenzoic acid) is universal
A kind of existing phenolic acid, in plant cell wall with polysaccharide and lignin crosslinking constitute cell wall a part, be asafoetide, when
Return, one of the effective elements of the medicine in Rhizoma Chuanxiong, cimicifugae foetidae etc., because that it is with stronger antioxidant activity and antisepsis is wide
It is general to be applied to medicine, health care product, cosmetic material and food additives aspect.Trans-ferulaic acid and its derivative are agriculturally being used
Has patent ZL200910229112.3.9 in active study of anti-plant viral disease, trans-ferulaic acid and its derivative can be effective
Prevention and treatment tobacco, wheat, tomato, melon dish, grain, vegetables, the various crops such as beans tobacco mosaic virus disease.Phase is developed
The blade face of pass is applied, but application study not yet is unfolded in seed treatment and processing of nourishing and generating.
China is longer using the history of seed treatment, and just there are lukewarm water bubble kind and Medicament soaked seed in ancient times, early in the Western Han Dynastry year
Between agriculture book " book of agriculture victory " in just it is on the books.From the 1950s, China starts to promote seed soaking, seed dressing technology for preventing
Subterranean pest-insect is controlled, the normal growth and development of seed is protected.Till now, develop is suitable for preventing and treating Different Crop, no in different regions
With a series of products of pest and disease damage, seed coat agent occupies certain share in plant protection in the market, effectively protects crop in seedling
Phase is infected by pest and disease damage, significantly reduces pesticide in the input amount of crop early stage, effect is significant in decrement volume increase.At this
In a little seed coat agents, seed coat agent is more with multi-functional, prevention and treatment multiple diseases joint product type seed coat agent, disease pest composite seed coating agent
40% or so of seed coat agent kind is accounted for, in addition there are some medicine fertilizer composite seed coating agents, but in antiviral seed treatment, disease-resistant
Malicious seed coat agent field still belongs to blank, also without forming the product being commercialized.Therefore, the Antiphytoviral kind of exploitation efficiently, less toxic
Son and nourish and generate that infect inorganic agent meaning very great.
Summary of the invention
