Description
[technical field]
The invention belongs to technical field of pesticide.More specifically, the present invention relates to a kind of biochemistry agricultural chemicals mixing-in fat acid supplement, also relate to the purposes of described mixing-in fat acid supplement.
[background technology]
The viroses of plant are a kind of global diseases, various crop such as the tobacco of causing harm, cotton, crudefiber crop, vegetables, paddy rice, wheat, peanut, soybean, melon, fruit tree and corn.China is a large agricultural country, and the plant economic loss that viral disease caused because of catching an illness reaches billions of units.Along with the influence of Global climate change, the generation of the viroses of plant is more and more serious, and the agricultural production of China in serious threat.
At present, China scientific research personnel has carried out many research work to the viroses of plant, has obtained marked improvement.For example CN102047883A discloses a kind of anti-plant virus composition that contains lentinan and brassin lactones.This anti-plant virus composition is an active ingredient with 0.5-5wt% lentinan and 0.0002-0.02wt% brassin lactones.Add ethanol, lauryl sodium sulfate and water and make aqua, adding lauryl sodium sulfate, white carbon, NNO, kaolin are made soluble powder or wetting powder.CN101589721 discloses a kind of control medicament of the viroses of plant.Described viroses of plant control medicament is made up of the component of following weight portion: Moroxydine Hydrochloride 4.0～97.0, amino-oligosaccharide 0.05～20.0, solubility filler 2.0～96.0.CN101869110A discloses a kind of anti-plant virus composition, and said composition is an active ingredient with 0.5-5wt% fucoidin and 0.5-5wt% ribavirin.The invention also discloses the application of this composition in control tomato virus disease or tobacco virus.CN101766195A also discloses a kind of composition that is used to prevent and treat the viroses of plant, and it is by weight ratio 1～6: two kinds of components of 2～9 A, B are formed; Wherein, described component A is the giant knotweed extract; Described B component is the plant resource surfactant, and its raw material by following percetage by weight is formed: plant protein amino-acid liquid 10%～40%, Chinese honey locust extract 20%～50%, Tea Saponin are mended to 100%.CN101438718 discloses a kind of medicine of Antiphytoviral, and it is with the Chinese toon extract, and Ningnanmycin and other auxiliary agent such as biodiesel are raw material, are formulated as the cream preparation of agricultural chemicals, wettable powder preparation, aqueous suspension preparation or aqueous dispersion preparation in proportion.Although these technology all have certain effect, they more or less exist some problems need continue to solve.At present, the medicament of control tobacco virus has only several kinds on the domestic market, as virus must restrain, OS executes the Trane, bacterium restrains that malicious gram, ZhiBingLing(SIC), pure land spirit, sterilization are upright to be escaped etc., control tobacco virus effect is all not ideal enough, because long-term use has produced certain pesticide resistance, and major part be chemical pesticide, prevents and treats cost height, contaminated environment, residual exceeding standard.
Do not see in the document abroad yet and prevent and treat the better medicament of the viroses of plant.
Therefore, the inventor has carried out big quantity research to new Antiphytoviral medicine, has finished the present invention finally.
