Description
Technical field
The present invention relates to a kind of Synergistic sterilizing glyphosate herbicidal composition, belong to agrochemical field.
Background technology
As the broad-spectrum herbicide that a kind of consumption is maximum, glyphosate is weed killer herbicide the most frequently used in the world at present.Glyphosate is inner-adsorption conduction-type herbicide, by the cauline leaf of plant absorb liquid backward under be transmitted to subterraneous root, each position of stem, the plant of the sections more than 40 such as unifacial leaf and dicotyledonous, annual and perennial, herbs and shrubs can be prevented and kill off.After glyphosate is manured into soil, very fast metal ion in soil is combined and loses activity, and therefore has no adverse effects to the seed in soil and microorganism.
In agriculture weeding practice, use glyphosate to reduce agricultural cost in large quantities, improve crop yield.But, along with the use that glyphosate is a large amount of, long-term, weeds can show certain resistance, China's glyphosate-resistant weeds mainly contains meadow pine (Drilgrass), Leersia Sw (trip grass), field bindweed, ear-piercing dish, Horseweed Herb, bamboo grass, youngia japonica etc., and their resistance level performances throughout the country differ.It is relevant that the appearance of Weed Resistance and the wax, cilium etc. on weeds surface reduce the absorption of weeds to glyphosate, and most importantly due to long-term, the single use Gyphosate herbicice in some areas, resistance glyphosate Weed Resistance increases, and becomes dominant population gradually.
In addition, glyphosate belongs to organic phosphates steriland herbicide, kills except speed is relatively slow, after general medicine, one week weeds just shows intoxication, shows as blade withered and yellow, and rear browning is withered, and the bacterial disease of weed killer herbicide to crops does not have preventive and therapeutic effect yet at present, effect is single.
Glyphosate according to its characteristic, the formulation of main application in the world at present has two kinds, and a kind of is the aqua of glyphosate salt, and another kind is the water-soluble granule type of glyphosate salt.It is aqua that glyphosate mainly processes types of formulation, aqua keeps original bioactive glyphosate salt directly to add water to make aqua, not containing visible exotic and precipitation, this formulation is easily processed, have that low poisoning, toxicity are little, easily dilutable, use safety and convenient, and there is good bioactive feature, receive praises from customers always.41% agriculture using high concentration aqua to first elect About Monsanto Chemicals's production in the world reaches (Roundup) aqua.Owing to using the Mon auxiliary agent of 15%, make this aqua have good physicochemical property and high biologically active and the safety to environment, become the leading products of weed killer herbicide in the world.Next is the 38% careless sulphur phosphorus aqua that company of Britain produces, and active component is glyphosate trimethyl sulfosalt, and stable in properties, has remarkable preventive effect to annual and perennial weed, suppresses weeds to reach more than 50 day, mainly uses in the country such as Europe, the United States, day.
Domestic, to produce ammonium glyphosate and the sodium salt of low concentration (10% or 15%), wherein the overwhelming majority does not add any auxiliary agent, and physicochemical property is poor, drug effect is low, loss is large, because production capacity is large, sell with lower production cost, be still active in Chinese glyphosate market.In addition, many producers also produce 41% glyphosate isopropylamine salt water solution to meet the needs of domestic and international market, but because making used additives bad or improper and cause difficulty in the international market to give competition.
Summary of the invention
In order to overcome problems of the prior art, the invention provides a kind of Synergistic sterilizing glyphosate herbicidal composition, not only can reduce the resistance of weeds to agricultural chemicals, effectively strengthen the herbicidal effect of glyphosate, and the bacterial disease of crops can be prevented and treated.
Technical scheme disclosed by the invention is:
A kind of Synergistic sterilizing glyphosate herbicidal composition, is characterized in that, be made up of the component of following percentage by weight: inner-adsorption conduction-type herbicide 70%, ammonium persulfate-sodium bisulfate 20%, auxiliary agent 10%.
Further, described inner-adsorption conduction-type herbicide is made up of the weed killer herbicide of following weight portion: glyphosate 20-50,2-first-4 chlorine 10-30.
Further, the active constituent content of described ammonium persulfate-sodium bisulfate is 42.8%-46%.
Further, described auxiliary agent is neopelex and polyethylene glycol.
Further, described glyphosate be 10% sodium glyphosate aqua or 15% sodium glyphosate aqua in one.
Further, described 2-first-4 chlorine be 13% 2-first-4 chlorine sodium salt or 20% 2-first-4 chlorine sodium salt aqua in one.
The above-mentioned glyphosate herbicidal composition of invention, preferably make aqua in conventional manner, the mass fraction of the active component of weed killer herbicide is 25%.
The dispenser phase: the growth animated period of weeds 2-4 leaf, height is best period below 10 centimetres; Should select in the sunny calm weather dispenser of following 5-7 days temperature more than 8 DEG C.
Usage: aqua weed killer herbicide disclosed by the invention is how many according to mu consumption, and the water of first admixture 1:1 makes the higher mother liquor of concentration, then fills half sprayer water, pours mother liquor into, then fills up required water, finally evenly uses.
Beneficial effect of the present invention:
1, the invention discloses a kind of mixed herbicide based on glyphosate, utilize the activity of synergistic effect raising to weeds between different weed killer herbicide, and overcome Long-Time Service single herbicide and bring out the problem that some weeds develops immunity to drugs to this weed killer herbicide, and because different weed killer herbicide can be prevented and treated different with the weeds kind controlled, namely herbicide spectrum is different, expands the weeds kind that weed killer herbicide can be prevented and treated and control.
2, weed killer herbicide is ejected into performance drug effect from sprayer, determines that the performance of pharmaceutically active needs through three phases: (1) liquid is delivered to target blade face from sprayer; (2) active constituents of medicine infiltrates through target blade face; (3) conduction of active constituents of medicine in strain grass blade leaf; Add auxiliary agent polyethylene glycol and neopelex, first, by changing the physicochemical property of spray liquid, can reduce the stage in (1), the loss caused because of the bounce-back of drop, loss, drift and evaporation, strengthens the stick effect of medicine on target blade face; Secondly, because of their surface-active property, can increase in the stage (2), the contact area on liquid and target blade face, improve the seepage velocity of active constituents of medicine, reduce the recrystallization phenomenon that active component may occur; In addition, auxiliary agent penetrates into lower-hierarchy by the diffusion of epidermis depth in the stage (3), destroys the integrality of cell membrane, and affect cell wall and plasma membrane to the absorption rate of glyphosate, therefore activity of weeding is higher;
3, by adding safety, environmental protection and novel strong oxidizer ammonium persulfate-sodium bisulfate that is efficient and one, utilizing its bactericidal action, the bacterial disease of crop can be prevented and treated.
