Abstract
The composite rice field phytocide contains bensulfuron methyl and MCPA as effective components as well as agriculture-acceptable carrier.
Description
The present invention relates to Herbicidal combinations, particularly the rice field Herbicidal combinations.
Up to now, herbicides for use in paddy appears in the newspapers repeatly.Sulfonylurea herbicide is a kind of of wherein herbicidal effect excellence.But in recent years, because the continuous use of sulfonylurea herbicide causes the weed community in the paddy field to develop.Weeds in the paddy rice from before be mainly the barnyard grass grass, but nowadays, sedge weed, convexutricle sedge herb etc. also becomes the main malignant weed in the paddy field, and crop smothering is more and more serious.Owing to lack the weed killer herbicide of wide spectrum, the way of solution, weed killer herbicide or artificial weeding once more, this just causes the increase of producing cost, and the application technique that dispenser for the second time requires is relatively stricter, and tends to occur poisoning.
Solving above-mentioned other method is to seek a kind of new weed killer herbicide, and disposable dispenser just can be prevented and kill off the different weeds of whole growing.Thereby the compound preparation has appearred, contain the also existing a lot of reports of compound preparation of sulfonylurea herbicide.Such as among the CN1074086A with bensulfuron, the Herbicidal combinations of metsulfuron-methyl and Acetochlor;
The weed killer herbicide of the compound preparation of the also disclosed ternary of CN109238A.The required component of disclosed composition is more in the above-mentioned patent application.The applicant's application number is also to disclose in 96100325.1 the patent application with bensulfuron-methyl and isopropyl methoxalamine as herbicides for use in paddy.
Because sulfonylurea herbicide is only effective to the convexutricle sedge herb class weeds that produce the initial stage, methoxone must be used with high dose could control these class weeds effectively, therefore, whether the combination of these two kinds of active components can become with low dosage, and to the effective weed killer herbicide of the whole growing of weeds, be the problem that the applicant pays close attention to, this also is the place of purpose of the present invention.
Herbicidal combinations of the present invention comprises the bensulfuron-methyl and the methoxone of herbicidally effective amount, and agricultural goes up acceptable carrier.
Methoxone also can be used its salt, comprises sylvite and sodium salt.Herbicidally effective amount refers to can prevent and treat and remove the amount of crop field weeds effectively, accounts for the weight of 0.1-99.9% usually in composition, and all the other are acceptable carrier on the agrochemistry.
The relative scale of bensulfuron-methyl and dichloro tetramethyl is 1 in the present composition: 2-10 (weight), preferably, and 1: 3～8, more preferably be 1: 5.
Composition can be made various formulations, but wet-milling for example, suspending agent, emulsion, dirt agent, granule, solution, missible oil or pill etc.In these formulations, but preferably use wet-milling or suspending agent.
Carrier in the described preparation is conventional those that use of agrochemical field, surfactant for example, filler, adhesive, emulsifier and solvent etc.
The example of solid carrier has clay class such as kaolin, montmorillonite, diatomite, bentonite, acid clay etc., talcum, and other inorganic mineral such as sericite mica, quartz, active carbon, calcium carbonate or the like.Liquid-carrier for example comprises solvent, water; Alcohols such as methyl alcohol, ethanol etc.; Ketone such as acetone, MEK etc.; Aromatic hydrocarbons such as benzene, toluene, dimethylbenzene, ethylbenzene, methyl naphthalene etc.; Fat hydrocarbon such as n-hexane, kerosene etc.; Ester class such as ethyl acetate, butyl acetate etc.; And ethers, amide-type and halogenated hydrocarbons etc.
The example of surfactant has alkyl sulfate, alkylsulfonate, alkylaryl sulfonate, aryl alkyl ethers, quaternary ammonium salt, polyvinyl chloride compound, polyoxyethylene glycol ester, polyol ethers, sugar alcohol etc.
The example of suspending agent comprises polyethylene glycol, polyvinylpyrrolidone, polyvinyl alcohol, polypropylene glycol and polysorbate etc.
The concrete ratio of active component in composition decided on formulation and operating position, but for example can account for 10-40% in the wet-milling, is preferably 15-20%, and suspending agent can account for 5-60% in emulsion and the solution, is preferably 10-30%, most preferably is 15-30%.
The invention still further relates to the application of Herbicidal combinations, comprise the present composition from herbicidally effective amount to the rice field that use.Usually the amount of application of composition is with every mu 0.5～7 gram of active component bensulfuron-methyl, and every mu 5～75 gram of methoxone is as the criterion, but for example 18% wet-milling can use 75-150 gram composition for every mu.The crop smothering situation of weeds also is the important references of amount of application.
Below the invention will be further described with specific embodiment.

Biologic test
One, test material and method
1. reagent agent: (1) but 18% the invention process 1 wet-milling
(2) 56% methoxone sodium pulvis (Fushun insecticide factory)
(3) but 30% bensulfuron-methyl wet-milling (du pont company produce, the farming of trade name prestige)
2. experimental field reach weeds: experimental field be located on the rice field in suburban area village, Harbin, soil is the carbonate meadow chernozemic soil, the content of organic matter 3.38%, and pH7.8, quality is gently sticking.The field convexutricle sedge herb is a flat bar Fischer grass (Scirpusplaniculmis).
3. test is handled: processing method sees Table 1
Table 1 test is handled

Three, result of the test
1. preventive effect
Flat bar Fischer grass is for blooming the Sheng phase during July 7 dispenser.Seedling is long for 15-20 centimetre high.Farming season flat bar Fischer grass showed severity on June 27 for coming into bloom, and seedling is 5-10 centimetre high.Preventive effect such as table 2.
Table 2 preventive effect

| Contrast | ????89.3 | ??????- | ????301.3 | ??????- | ????503.3 | ??????- |
2. the influence that paddy rice is given birth to
Observe after the dispenser, singly execute the rice seedling leaf look chlorisis flavescence in mcpa sodium district.The plant fertility is slow, and all the other are handled and do not find symptom of chemical damage.
Because flat bar Fischer grass is after 10 centimetres, the prestige farming is to its poor effect, and it is bigger to the rice seedling influence singly to execute methoxone, and its reasonable combination is become compound preparation, can prevent and treat the convexutricle sedge herb of different times, and this is the place of characteristics of the present invention.
