Abstract
A kill-type herbicide contains active components (glyphosate and MCPA in weight ratio of (1-15):(1-3), disperser, wetting agent, surfactant and filler. Its advantages are high effect and low cost.
Description
The invention belongs to chemical pesticide, relate in particular to a kind of steriland herbicide.
Complex weedicide of the present invention relates to two kinds of active ingredients, and a kind of is glyphosate, and another kind is 2 first, 4 chlorine.
Glyphosate (glyphosate) molecular formula is C
3H
8O
3NP, chemical name are N-(phosphoric acid methyl) glycine, and its structural formula is:
2 first, 4 chlorine (agroxone) molecular formula is C
9H
9O
3Cl (Na), chemical name are 2-methyl-4-chlorophenoxyacetic acid (sodium), and its structural formula is:
Glyphosate is an inner sucting conduction type wide spectrum steriland herbicide, can prevent and kill off nearly all annual or perennial weed.But, to dissimilar weeds using dosage differences.To the responsive type weeds, 10% glyphosate mu dosage is 250-500ml, and cost is a 1.5-3.0 unit; To general responsive type weeds, 10% glyphosate mu dosage is 500-1000ml, and cost is a 3.0-6.0 unit; To the drug resistance weeds, 10% glyphosate mu dosage is 1000-2000ml, and cost is a 6.0-12.0 unit; But it is still relatively poor to effects such as Drilgrasses.On producing, most fields piece responsive type, general responsive type, drug-resistant type weeds mix takes place, if the using dosage of 10% glyphosate is a 200-500ml/ mu, herbicidal effect is undesirable; The using dosage of glyphosate improves, though can reach desirable herbicidal effect, the also corresponding raising of weeding cost.The dosage that 20%2 first, 4 chlorine use separately is 150-300ml/ mu, and cost is a 1.5-3.0 unit.2 first, 4 chlorine are good to broad leaved weed and sedge weed preventive effect, but bad to aging weeds plant effect.Very sensitive to the gramineous plants seedling, 4 leaf phases played resistance and strengthen, and tillering stage is the strongest, and panicle spike primordium differentiation stage susceptibility rises again, therefore were difficult to solve numerous grassy weeds.
In sum, the problem that existing glyphosate exists is will strengthen general responsive type and drug-resistant type weeds using dosage, and cost rises at double.2 first, 4 chlorine are also infeasible as steriland herbicide separately.If glyphosate and 2 first, 4 chlorine are used with, even to the drug-resistant type weeds, the using dosage of glyphosate need not strengthen, and also can reach desirable herbicidal effect.But in actual mechanical process, the one, use dosage with and be difficult for to grasp, the 2nd, use with by the dosage that glyphosate, 2 first, 4 chlorine use separately, cost is also than higher, thereby in the rural area and other occasion be difficult to promote the use of.
The objective of the invention is shortcoming, a kind of Compositional type steriland herbicide is provided, both can enlarge and kill grass spectrum, raising herbicidal effect, can reduce the weeding cost effectively again at prior art.
Steriland herbicide of the present invention is an active ingredient with glyphosate and 2 first, 4 chlorine, and adds composite forming such as wetting agent, bleeding agent, dispersant, stabilizing agent, solubilizer, filler, and wherein the weight ratio of glyphosate and 2 first, 4 chlorine is 1-15: 1-3.
The auxiliary agent that wetting agent, bleeding agent, dispersant, stabilizing agent, solubilizer, filler all adopt general Recompounded pesticide to use always, wherein wetting and bleeding agent has lignosulfonates, detergent LS, penetrating agent JFC 885, sodium alkyl sulfate (sodium alkyl sulfate), sodium alkyl benzene sulfonate, azone, alkylphenol polyoxyethylene etc.; Dispersant has lignosulfonates, alkylnaphthalene sulfonate (based on sodium salt), naphthalenesulfonic acid-formaldehyde condensate (NNO) etc.; Stabilizing agent and solubilizer polysiloxane class, organophosphorus compounds, also has high molecular polymer, as Sodium Polyacrylate, polyvinyl alcohol, polyvinylpyrrolidone, carboxymethyl cellulose, quaternary amine etc.; Filler has alkali carbonate, bicarbonate, ammonium carbonate, ammonium sulfate, urea, white carbon, precipitated calcium carbonate etc.
Steriland herbicide of the present invention, its composition and content are (percetage by weight):
Glyphosate 1-80%
2 first, 4 chlorine 0.1-50%
Wetting agent 0.1-10%
Bleeding agent 0.01-10%
Dispersant 1-10%
Stabilizing agent 0-10%
Solubilizer 0-10%
The filler surplus
Steriland herbicide of the present invention, its preparation method has spraying cooling molding method, comminuting method, seasoning etc., wherein the breaking plant of comminuting method employing has micronizer and airslide disintegrating mill, production process is as follows: quantitative former medicine and solid additive are joined in the mixer mix, mixed material is pulverized in cracker through feeder, material after the pulverizing enters into intermediate bunker by cyclone separator and sack cleaner, add quantitative liquid adjuvants and filler after the metering again, after agravic mixing, be finished product.
Steriland herbicide of the present invention, the formulation that can be processed into have soluble powder SP, solubility grain (sheet) agent SG, wetting powder WP, water-dispersion type granula WG, solid colloidal suspending agent DF etc., for the convenience of using and transporting, mainly adopt soluble powder.
Steriland herbicide of the present invention, be applicable to tea place, mulberry field, orchard, cane field, rubber plantation, the field of lying fallow, weeding before the field sowing that paddy and wheat, rape field etc. are no-tillage, the weeding of cotton field middle and later periods, and limit, field, roadside, channel, railway, airport, oil depot and flower garden weeding.
Advantage of the present invention and remarkable result:
1. herbicidal effect is splendid:
, use at the weed growth animated period all above 90% for the overall herbicidal effects of various grass family, sedge family and broad-leaved section weeds, herbicidal effect can reach more than 95%.
2. it is wider to kill the grass spectrum:
Single agent glyphosate adopts routine dose effectively not kill and removes general responsive type weeds, and is poorer to drug-resistant type weeds effect.Single agent 2 first 4 chlorine are invalid substantially to grassy weed.And the complex preparation of glyphosate and 2 first, 4 chlorine can remedy the weakness of glyphosate to general responsive type weeds and drug-resistant type weeds effect aspect, also can remedy 2 first, the 4 chlorine defective invalid substantially to grassy weed, kill the grass spectrum thereby enlarge greatly, be enough to prevent and kill off most weeds of various occasions.
3. it is faster to kill careless speed
Since glyphosate and 2 first, 4 chlorine uniquenesses kill careless mechanism, the two acts on weeds simultaneously, can accelerate weeds yellow-browning-withered.Experimental result shows, the weeds yellow-browning-withered time ratio list that uses glyphosate and 2 first, 4 chlorine complex preparations was with glyphosate early 1-3 days.
4. cost descends, remarkable in economical benefits
Because have certain synergistic effect after glyphosate and 2 first, 4 chlorine are processed into complex preparation, the using dosage of glyphosate need not increase, with significantly reducing, cost is the using dosage of 2 first, 4 chlorine than single
5. reduce dosage and medication number of times, reduce environmental pollution
Glyphosate and 2 first, 4 chlorine complex preparations are broad weed-killing spectrum not only, and herbicidal effect is good, speed is fast, and a drug can solve nearly all weeds of various occasions, with the glyphosate list with comparing, can reduce the medication number of times.Send out owing to most occasion responsive type weeds mix with general responsive type, drug-resistant type weeds, when list was used glyphosate, using dosage must strengthen; And with glyphosate and 2 first, 4 chlorine complex preparations, the dosage of glyphosate, 2 first, 4 chlorine is all low with dosage than single, thereby has reduced dosage, reduces the pollution to environment.
6. transportation, packing, easy to use
Glyphosate in the market, 2 first, the 4 chlorine overwhelming majority are aquas, and content is lower, adopt Plastic Drum or bottle packing, crush easily in the transportation, make troubles also for retail, use, and cause misuse easily, cause unnecessary loss.Glyphosate of the present invention and 2 first, 4 chlorine complex preparations can be made into soluble powder, and packing, transportation, retail, use are all very convenient.
