Abstract
A method of controlling unde ired vegetation in a rice crop comprising applying to the locus where control is desired a herbicidal amount of prosulfocarb.
Description
The present invention relates to a kind of by using the method for unwanted plant in prosulfocarb (683) the control rice crops.
Unwanted plant such as weeds and gramineous plants are the last problems that repeats of agricultural by consuming valuable land area or soil nutrient inhibition plant growth.For overcoming this problem, a variety of chemicalss and chemicals have been produced as herbicide application.Disclose the weed killer herbicide of many types in the document, and had a large amount of weed killer herbicides commercial.
One class weed killer herbicide is a thiocarbamates.US-A-4695314 discloses some thiocarbamates and has shown preventive and therapeutic effect to weeds in the rice crops.
Have now found that no matter another kind of Thiourethane compound prosulfocarb (683) is before the seedling or behind the seedling, all the unwanted plant in the rice crops is had good preventive and therapeutic effect.
Therefore, first aspect of the present invention provides a kind of method of preventing and treating unwanted plant in the rice crops, comprises prosulfocarb (683) from herbicidally effective amount to the place of needs control that use.
In an embodiment of first aspect, prosulfocarb is used with the composition forms that comprises prosulfocarb and at least a conventional inert formulation auxiliary agent.
Aspect second, the invention provides the purposes of unwanted plant in the prosulfocarb control rice crops.
Electronic edition The e-Pesticide Manula, 3.0 versions, the 13rd edition, editor CDCTomlin, British Crop Protection Council, 2003-04 provides commercial herbicides compounds to comprise the details of prosulfocarb.Numeral after the compound title is the entry number that provides among the Pesticide Manual.
Unwanted plant is that those influence the growth of rice and the plant of quality, and example comprises gramineous plants and broad leaved weed.The prosulfocarb of herbicidally effective amount is administered to the zone that is suitable for preventing and treating unwanted plant acts on the cultural area of unwanted plant or rice crops to make it.Cultural area is that crop plants has been grown or sowed the zone, soil of the seed material of those crops, and plans the zones, soil of those crops of plantation.
But crop yield and quality to the control satisfaction guaranted of unwanted plant, though the crop-planting person often must use balance between relevant cost of herbicides compounds and the last output that obtains,, the control that it has been generally acknowledged that compound compares the output increase of the crop of having handled for example at least 5% but making with untreated crop.
Prosulfocarb can be used for resisting gramineous plants important on a large amount of agriculturals and broad leaved weed, like rain Pittosporum of a specified duration, Vandellia, ludwigia, Elatine ambigua, ludwigia, flower Lin genus, Ipomoea, chrysanthemum Lin genus, mexicana, arrowhead genus, cusp Pittosporum, eleusine indica, Echinochloa, Sprangletop, knotgrass, setaria, Paspalum, Rottboellia exaltata L. F, Brachiaria and ischaemum, with annual and perennial nutgrass flatsedge, for example the Fischer grass belongs to (for example firefly Lin), Cyperus, Eleocharis and genus fimbristylis.
Found that prosulfocarb can prevent and treat the unwanted plant in the rice crops especially effectively, described plant produces resistance to acetolactate synthestase (ALS) inhibitor, belongs to and Cyperus as Vandellia, Monochoria, Elatine ambigua, Fischer grass.Prosulfocarb is effective especially to Lindernia Dubia, Monochoria vaginalis or three stamen waterworts.
Prosulfocarb is applicable to conventional all application processes used of agricultural, for example preemergence application and postemergence application.
Consumption can change in wide region, depends on the unwanted plant of character, application process (before the seedling or Miao Hou etc.), the desire control of soil, main weather conditions and by other factors of application process control, and time of application.In active component, prosulfocarb is usually with 0.01-10kg/ha, and the consumption of preferred 0.1-7kg/ha, particularly 1-5kg/ha is used.
The form use that prosulfocarb can unprocessed form promptly obtains in synthetic, but use with the form of composition (or preparation) usually, in preparation technique auxiliary agent commonly used such as solvent, solid carrier or surfactant and optional one or more other have pest activity extremely such as an activity of weeding compound as for example being mixed with missible oil as described in the WO97/34483 9-13 page or leaf, can directly spraying or dilutable solution, wetting powder, soluble powder, dust agent, granule or microcapsule formulations.As the character of composition, according to its intended purposes and main environmental selection application process as spray, atomize, dust, wetting, spreading or cast.Preparation prepares in known manner, for example by active component and formulation auxiliary agents such as solvent or solid carrier directly being mixed and/or grinding preparation.In addition, in the preparation process of preparation, also can add surface active cpd (surfactant).
The example of solvent and solid carrier provides in the 6th page of WO97/34485 for example.According to the character of the active component of desire preparation, suitable surface active cpd is nonionic, cation and/or anion surfactant and the surfactant mixture with good emulsifying, dispersion and wetability.The example of suitable anion, nonionic and cationic surfactant is listed in the 7th and 8 page of WO97/34485 for example.The conventional surfactant that uses also is applicable to preparation Herbicidal combinations of the present invention in the preparation processing technology, described surfactant is described in " McCutcheon ' s Detergents and Emulsifiers Annual " MC PublishingCorp. especially, Ridgewood New Jersey, 1981, Stache, H., " Tensid-Taschenbuch ", Carl Hanser Verlag, Munich/Vienna, 1981 and M.and J.Ash, " Encyclopedia of Surfactants ", the I-III volume, Chemical Publishing Co., New York is among the 1980-81.
Herbicidal formulations contains the active component of 0.1-99wt%, particularly 0.1-95wt% usually, the surfactant of 0-25wt%, particularly 0.1-25wt%, and surplus is solid or liquid preparation auxiliary agent.
Though preferred commercially available prod is formulated into concentrate usually, the end user generally can use the preparation of dilution.Composition also can comprise for example for example silicone oil, preservative, viscosity modifier, adhesive, tackifier of vegetable oil or epoxidized vegetable oil (epoxidation cocoa butter, rapeseed oil or soya-bean oil), defoamer of other compositions such as stabilizing agent, also has fertilizer or other active components.
The following example unrestricted the present invention and providing for explanation.
Biological Examples
The ALS resistance seed of each weeds kind is planted in the normally used greenhouse jar.Dispenser is that water consumption is 2001/ha indoor the carrying out of dispenser of sealing.Test be at random and carry out 4 times and repeat.Estimate the control of weeds grade after the dispenser 21 days the time, represent with 100% ratio.
Table 1 shows, and the weed killer herbicide that generally is used for rice crops: molinate (thiocarbamate) is compared with cinosulfuron, and prosulfocarb has shown the unexpected control efficiency to unwanted plant.
