Description
Technical field
The invention belongs to technical field of pesticide, relate to a kind of mixed herbicide including cloransulammethyl and clomazone two kinds of active ingredients, and the preparation method and application of this kind of mixed herbicide.。
Background technology
Cloransulammethyl (cloransulam-methy), the chloro-2-of chemical name: 3-(5-ethyoxyl-7-fluorine [1, 2, 4] triazole [1, 5-c] pyrimidine-2-base sulfonyl) Methyl anthranilate, belong to sulfonamides herbicide, there is Uptake and translocation, weeds root system and cauline leaf all can absorb medicament, and conduct up and down by xylem and phloem, finally be accumulated in plant meristematic tissue, by suppressing acetolactate synthestase, suppress the biosynthesis of branched-chain amino acid, cause weeds body internal protein biosynthesis block, weed growth is caused to be stagnated then dead.The existing cauline leaf treatment effect of this medicament also has soil sealing process, main application sprays for planting front soil table, use the broad leaved weed preventing and treating Soybean Field before bud after bud, have special efficacy to " three dishes " (dayflower, corn sow thistle, field thistle), but it is invalid to grassy weed.
Clomazone (clomazone), other common names: clomazone, clomazone, chemical name: 2-(2-chlorobenzyl)-4,4-dimethyl isoxazole-3-ketone.Clomazone is the Yi Lei oxazole class selectivity preemergence herbicide of FMC Corp.'s initiative, also can make post-emergence herbicide to use, absorbed by root, bud, affect carotin and chlorophyllous biosynthesis, thus by suppressing photosynthesis of plant two to cause plant dead, being mainly used in legume and preventing and kill off annual gramineous weed and part broad leaved weed.As annual gramineae and the broad leaved weed such as barnyard grass, green foxtail, lady's-grass, setaria glauca, eleusine indica, black nightshade, elscholtiza, water sour jujube pin, kitchen garden, piemarker, flowerofanhour root or herb, lamb's-quarters, little lamb's-quarters, penny cress, willow leaf thorn knotweed, pale persicaria, dayflower, the rare Xian of hair, bur beggar-ticks, beggar-ticks, Siberian cocklebur, artemisiifolia, there is stronger inhibitory action to perennial field thistle, setose thistle, corn sow thistle, meadow pine etc.
Current Soybean herbicides limit by safety, herbicide spectrum is also limited, be used alone the generation that a kind of weed killer herbicide single dose can not control soybean weeds completely effectively, moreover some weed killer herbicide is due to water-soluble large or the field lasting period is oversize, consumption is excessive or dispenser is uneven all easily causes residual hazard.
Summary of the invention
It is limited that the object of the invention is to solve simple weed killer herbicide herbicide spectrum in prior art, and security hidden trouble, provides one mixed herbicide efficiently and safely.

Other, as bonding agent, dispersant, spreading agent, sticker, antifreezing agent, anticaking agent, anti-decomposition agent etc., if dispersant is if di-2-ethylhexylphosphine oxide bitter edible plant sodium sulfonate, thickener are as white carbon, be not particularly limited, the material that can realize identical function of any this area, can mix or in single application and the present invention.
8. above-mentioned 7 mixed herbicides provided, its formulation is missible oil, suspending agent, aqueous emulsion, microemulsion, wetting powder, water dispersible granules.
9. above-mentioned 6 preparation methods that mixed herbicide is provided, comprise and cloransulammethyl and clomazone are mixed according to both certainty ratios, add agricultural agent, carry out stirring and evenly mixing, form creamy, suspension, water and milk shape, microemulsion, wettable powdery, the granular mixed herbicide of aqueous dispersion.
Set ratio refers to the ratio set forth in method described in above-mentioned any one of 1-6, the kind of the plant removed as required, needs the herbicidal effect setting reached.According to the difference of the agricultural agent added, the mixed herbicide formulation of formation can be missible oil, suspending agent, aqueous emulsion, microemulsion, wetting powder, water dispersible granules.
10. the mixed herbicide that provides of above-mentioned any one of 1-8 is removing the application in Soybean Field in grassy weed and broad leaved weed.
Grassy weed and broad leaved weed mainly comprise barnyard grass, green foxtail, lady's-grass, setaria glauca, eleusine indica, black nightshade, elscholtiza, water sour jujube pin, kitchen garden, piemarker, flowerofanhour root or herb, lamb's-quarters, little lamb's-quarters, penny cress, willow leaf thorn knotweed, pale persicaria, dayflower, the rare Xian of hair, bur beggar-ticks, beggar-ticks, Siberian cocklebur, artemisiifolia, dayflower, corn sow thistle, field thistle etc.
Beneficial effect:
1, activity of weeding is high.Cloransulammethyl belongs to sulfonamides herbicide, there is Uptake and translocation, weeds root system and cauline leaf all can absorb medicament, and conduct up and down by xylem and phloem, finally be accumulated in plant meristematic tissue, by suppressing acetolactate synthestase, suppressing the biosynthesis of branched-chain amino acid, cause weeds body internal protein biosynthesis block, cause weed growth to be stagnated then dead.Clomazone is absorbed by root, bud, affects carotin and chlorophyllous biosynthesis, thus by suppressing photosynthesis of plant two to cause plant dead.That is, herbicidal composition of the present invention can kill weeds by two kinds of different approaches, greatly can improve the removing activity of weed killer herbicide.
2, action time is wider, easy to use.Cloransulammethyl both can spray for soil table before plantation, also can for using after bud before bud; Clomazone is Yi Lei oxazole class selectivity preemergence herbicide, and also can make post-emergence herbicide and use, the two with the use of carrying out control of weeds in the whole process of crop growth, and produces good result.
3, herbicidal spectrum is wide, and the lasting period is long.After cloransulammethyl mixes with clomazone, action compensating, herbicidal spectrum is wider, and weed killer herbicide of the present invention has the double action in cauline leaf process and feud, extends the lasting period of medicament.
4, safety is high.Herbicidal composition of the present invention, is applied in Soybean Field, and it can prevent and kill off various grassy weed in soybean, under the prerequisite that improve drug effect, has very high safety to soybean crops.
Therefore, in sum, mixed herbicide provided by the invention has high-efficiency broad spectrum, reduces pesticide usage amount, reduces residue of pesticide, Environmental compatibility is good, to advantages such as person poultry safeties, is the soybean crops chemical herbicide of high-quality.
