Abstract
The present invention relates to a compound dry land herbicide which is formed by compounding the effective components of 1 to 50% of acetochlor and 0.1 to 50% of clomazone and adding a wetting agent, a dispersing agent, an emulsifying agent, filler, etc. The compound herbicide can enlarge the weeding spectrum and enhance the weeding effect as well as decrease the using times, delay the chemical resistance of weed and reduce environmental pollution.
Description
One, technical field
The invention relates to a kind of agricultural chemicals, relate in particular to a kind of dry land herbicide that contains Acetochlor and clomazone.
Two, background technology
" agriculture chemical registration bulletin compilation " 1998, open day: disclose a kind of wetting powder in May, 1999, it contained 45% Acetochlor and clomazone missible oil, and is different with prescription of the present invention although it is effectively, and drug effect and preventive effect are also inequality.
Acetochlor (acetochlor) molecular formula is C
11H
20CLNO
2, chemical name is that 2-chloro-N-ethoxymethyl-6-acetyl-O-replaces aniline, its structural formula is:
Clomazone (clomazone) molecular formula is C
12H
14CLNO
2, chemical name is 2-(2-benzyl chloride base)-4,4-dimethyl isoxazole-3-ketone, and its structural formula is:
Acetochlor is the selectivity preemergence herbicide, can prevent and kill off annual gramineous weed and some annual broadleaf weed, but undesirable to some broad leaved weed preventive effect.Clomazone is an oxazole ketone selectivity preemergence herbicide, is mainly used in the soybean field and prevents and kill off broad leaved weed, but use clomazone missible oil cost higher, dangerous separately, and seriously polluted.
Three, summary of the invention
The objective of the invention is shortcoming, a kind of Compositional type dry land herbicide is provided, both can enlarge and kill grass spectrum, raising herbicidal effect, can reduce the weeding cost effectively again at prior art.
Dry land herbicide of the present invention is an active ingredient with Acetochlor and clomazone, and adds composite forming such as wetting agent, dispersant, emulsifier, filler.
The auxiliary agent that wetting agent, dispersant, emulsifier, filler all adopt general Recompounded pesticide to use always, wherein wetting agent has sodium alkyl sulfate, neopelex, Negel etc.; Dispersant has lignosulfonates, naphthalenesulfonic acid-formaldehyde condensate (NNO) etc.; Emulsifier is farming breast 8205, farming breast 500, farming breast 600 etc.; Filler has white carbon, precipitated calcium carbonate, bentonite etc.
Steriland herbicide of the present invention, its composition and content are (percetage by weight):
Acetochlor 1～50%
Clomazone 0.1～50%
Wetting agent 0.1～10%
Dispersant 0.1～10%
Emulsifier 1～12%
The filler surplus.
Be preferably, mixed herbicide for dry land of the present invention, the composition of weed killer herbicide and content are (percetage by weight):
Acetochlor 25%
Clomazone 10%
Sodium lignin sulfonate 4%
Farming breast 500 5%
Neopelex 0.5%
White carbon 30%
The precipitated calcium carbonate surplus.
Dry land herbicide of the present invention, its preparation method have spraying cooling molding method, comminuting method, seasoning etc., and wherein the breaking plant of comminuting method employing has micronizer and airslide disintegrating mill.Production process is as follows: quantitative solid additive and filler 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 crude after the metering again, after agravic mixing, be finished product.
Dry land herbicide of the present invention, the formulation that can be processed into have wetting powder WP, suspending agent SC, microemulsion ME, aqueous emulsion EW etc., mainly based on wetting powder WP.
Dry land herbicide of the present invention, be applicable to that the back seedling is broadcast in soybean, rape, cotton, sugarcane, peanut field etc. before, the weeds budding period weeding of being unearthed.
Advantage of the present invention and remarkable result:
1, enlarged grass spectrum extremely
Single agent Acetochlor and single agent clomazone all are selectivity preemergence herbicides, can not prevent and kill off most of fields piece and mix the various weeds of taking place.After Acetochlor and clomazone are re-dubbed novel formulation, utilize two kinds of mechanisms of action that medicament is different, enlarge and kill the grass spectrum.
2, improve herbicidal effect
After using mixture, not only satisfactory for result, weeding is fast to current subject, and use the back weeds and be difficult for sprouting again, reach the effect of long-term control weeds.
3, delay the weeds pesticide resistance and produce, reduce cost, reduce environmental pollution
Because after Acetochlor and clomazone are processed into complex preparation, reduced the dosage of independent use Acetochlor and clomazone, and dispenser prolongs at interval, be unfavorable for the drug-fast generation of weeds, thereby reduced dosage and medication number of times, reduced drug cost and the pollution of environment.
4, use and convenient transportation
Acetochlor, the clomazone overwhelming majority are missible oil in the market, and packing, retail and use are all inconvenient, crush easily again in the transportation, cause unnecessary loss.The present invention is mixed with wetting powder with Acetochlor and clomazone, and volume reduces, and packing, transportation and use are all very convenient.
Four, embodiment
Below further specify the present invention by specific embodiment, but embodiment only be used for the explanation, can not limit the scope of the invention.
Embodiment 1:
