Description
Technical field
The invention belongs to pesticide field, more particularly relate to the purposes as the synergist of the bactericidal suspending agent of non-seed treatment by polyvinylpyrrolidone.
In the present invention, bactericidal suspending agent refers to the suspending agent preparation in bactericide.
Background technology
Polyvinylpyrrolidone compound itself does not almost have activity to disease fungus sterilization, and conventionally in medicine and field of veterinary, be used as adhesive, suspending agent, perforating agent and thickener, and in pesticide field, only find to be used as adhesive in the seed treatment of minority, have no in disinfectant use in agriculture field it as synergist, to improve bactericidal effect and to accelerate the report of sterilization speed.
Polyvinylpyrrolidone is commercially produced, and can buy acquisition by commercial sources.
Cell wall outermost one deck of most hypha,hyphaes is to consist of β-(1,3) glucan or α-(1,3) glucan.This class β-(1,3) glucan or α-(1,3) glucan is that helical form is without the dense matter of branch's backbone.This class dense matter can effectively intercept other material and enter in fungal cell.Therefore, the bactericidal action approach of traditional disinfectant use in agriculture is after absorbing by plant, then the picked-up to plant nutrient by fungi, and follows nutrient to enter in fungal cell, thereby realizes direct sterilizing function; Or when fungus spore germination, because spore surface is not by β-(1,3) glucan or this class dense matter parcel of α-(1,3) glucan, by direct absorption of spore, played bactericidal action.
Therefore, up to the present, the R&D direction of disinfectant use in agriculture is to continually develop to be more conducive to the Fungicidal active compound that plant absorbs always, or, extend the ability that Fungicidal active compound continues to suppress spore germination or kills spore at plant surface.
By plant, absorb the method that plays bactericidal action, must first guarantee that the bactericide guarantee fungi of plant absorption sufficient amount absorbs the bactericide of enough sterilization doses.This method causes invalid (biological target utilization ratio is low) and the residue problem of unnecessary bactericide in plant corpus on the one hand, meanwhile, also easily plant is produced to poisoning.And this mode of action, has extended the time that bactericide arrives target thalline, generally, use traditional bactericide needs just can take effect at least 48 hours later; So, for the disease of systemic infection, as epidemic disease etc., when finding to make deposits yields disease, use bactericide, while telling on to bactericide, crop has produced heavy losses again.
Prolongation Fungicidal active compound, in the method for plant surface duration, also causes plant surface bactericide to keep higher concentration, and residual quantity increases.
Therefore, aforementioned these two kinds of R&D directions have all increased bactericide in making object or surface residual.
Summary of the invention
We are in research process; unexpected discovery; polyvinylpyrrolidone can help bactericide directly to break through the β on hypha,hyphae cell wall surface-(1; 3) glucan or α-(1; 3) iris action of this layer of dense matter of glucan; thereby play the lethal dose that is subject to that can directly reach target thalline with the bactericide of less dosage; thereby improve the sterilization speed of bactericide, the consumption of minimizing bactericide; to realize the crop protection object with environmentally friendly, low cost and low-residual mode, and improve the safety of bactericide to crop.
By following test, can illustrate well that polyvinylpyrrolidone can be broken through hypha,hyphae cell wall outermost 1, this layer of fine and close barrier material of 3-glucan.
We are respectively with the polyvinylpyrrolidone (K15 that commonly uses model, K30, K60, K90, all be purchased from German BASF AG), conventional emulsifier tween 80 (Tween80) and dispersant sodium lignin sulfonate, and the PVP K30 of the most frequently used model and conventional emulsifier tween 80 (Tween80) and the mixture of sodium lignin sulfonate, and clear water, acidity and alkaline aqueous solution, by representative hypha,hyphae [the raw single shaft mould (Plasmopara viticola (Berk et.Curt) BerletdeToui) of grape, Siberian cocklebur monofilament shell bacterium (Sphaerothecafuliginea (Schl.) Poll.F.xanthii Jacz.), mushroom bacterium (Lentinus edodes (Berk.) Sing.) and Penicillium citrinum (Penicillium citrinum Thom)] soak 2 minutes, then use 0.01% Coomassie brilliant blue (G-250) dyeing 2 minutes, rinsing 2 minutes in clear water respectively, and with repeating rinsing in clear water once, then mycelia is placed in to the coloration result of observation to mycelia under 160 power microscopes.The results are shown in subordinate list 1.
Subordinate list 1: representative hypha,hyphae is contrasted the coloration result after processing
Note: in subordinate list 1, "+" represents that mycelia is dyed to as vivid blueness, "-" represent mycelia and be not colored.
The result of the test explanation of subordinate list 1:
1) after the HC1 aqueous solution that the NaOH aqueous solution that is 9 through clear water, pH value, pH value are 4, the 0.3% Tween 80 aqueous solution, 0.3% sodium lignin sulfonate aqueous solution soaking, hypha,hyphae can not be by coomassie brilliant blue staining, reason is that these aqueous solution cannot be broken through hypha,hyphae cell wall outermost layer structure, thereby can not make Coomassie brilliant blue enter cell wall internal layer, its protein is dyeed.
2) after the polyvinylpyrrolidone aqueous solution soaking of variable concentrations, different model, the raw single shaft of grape is mould, Siberian cocklebur monofilament shell bacterium, mushroom bacterium and Penicillium citrinum can be by coomassie brilliant blue stainings, reason is that these hypha,hyphae cell wall outermost layers are by 1,3-glucan forms, the polyvinylpyrrolidone of variable concentrations, different model all can be broken through the fungal cell wall skin that 1,3-glucan forms.
Based on above-mentioned unexpected discovery, the present invention proposes following technical scheme:
Polyvinylpyrrolidone is as the purposes of the synergist of agricultural bactericidal suspending agent, and wherein, the mean molecule quantity of polyvinylpyrrolidone is preferably 500-1, and 100,000, more preferably 1,000-900,000, most preferably be 5,000-700,000.
