Abstract

A method of controlling weeds, especially rice that has become wild or degenerated, in cultivated rice by the application of herbicidal compositions by means of dripping application.

Description

The method of undesired plant growth in the control rice
The present invention relates to a kind of new method of preventing and treating undesired plant growth in the rice crops.
As everyone knows, it is unwelcome that weeds have particularly become the appearance of rice (weeds are like rice) in cultivated rice wild or that degenerate, because this quality that can cause gathering in the crops rice descends.Yet having become rice wild or that degenerate can not prevent and treat with selective herbicide because literally meaning it be not weeds.Since to by for example plow, when soil in the rice field is prepared in rotary tillage, mixed soil layer etc., described weeds germinate usually, some existing rice wild or that degenerate can be removed in these processes, but it is positioned at soil and can not removes than the seed and the seedling of depths.They can not be subjected to suppress the ground growth, afterwards with the cultivated rice competition that is seeded in the vernalization on the wetted surface of field.
The objective of the invention is to propose a kind of method, can prevent and treat the wet weeds of broadcasting in (wet-seeded) rice crops effectively, particularly become rice wild or that degenerate by this method.
The objective of the invention is by in leveling operation the commercially available rice herbicides of routine being applied in the waterflooding rice field by dripping, the leveling operation means that usually the preparation of paddy soil finishes.
Therefore, the present invention relates to a kind of wet method for weed of broadcasting in the rice crops of preventing and treating, wherein before the cultivated rice of sowing vernalization, in the leveling operation will to rice selectively herbicidal composition infect the field by dripping the weeds that are applied to waterflooding.
Of the present invention to rice selectively Herbicidal combinations contain to rice selectively weed killer herbicide or in conjunction with the weed killer herbicide of or the non-selectivity lower of safener to the rice selectivity as active component.
In pretreated rice field as mentioned above, can the height controlling weeds, particularly become rice wild or that degenerate.Although used weed killer herbicide (when it is the lower or nonselective herbicide of selectivity) can be attacked the cultivated rice of the vernalization of sowing afterwards, can survive described attack by means of safener cultivated rice only by root absorption.Yet weeds are not like this, because its root is embedded in the soil too far, so safener can not enter plant by root.Plant all is exposed to the herbicide action via the hypocotyl performance, and is therefore dead.
Be applicable to that rice herbicides of the present invention is that itself is known, commercially available and be described in for example ThePesticide Manual, the 12nd edition, BCPC, 2000.Described weed killer herbicide is particularly including Acetochlor, amicarbazone, two careless ethers, butachlor, benzofenap, azoles acyl grass amine, clomazone, dithiopyr, esprocarb, fentrazamide, flufenacet, isoxaflutole, hexazinone, mefenacet, mesotrione, isopropyl methoxalamine, the S-isopropyl methoxalamine, oryzalin, oxadiazon, oxadiargyl, pendimethalin, penoxsuam, pethoxamid, the third careless amine, Stam F-34, prosulfocarb, pyrazolate, pyriftalid, KIH 6127, pyribenzoxim, the sulphur humulone, sulfentrazone, P DimethenamidP and benthiocarb.
Particularly preferred rice herbicides is Acetochlor, butachlor, S-isopropyl methoxalamine, the third careless amine, prosulfocarb, pyriftalid and pyribenzoxim, particularly importantly third careless amine and the butachlor.
The common rice herbicides that uses with safener is Acetochlor, butachlor, flufenacet, mesotrione, isopropyl methoxalamine, S-isopropyl methoxalamine, the third careless amine, prosulfocarb and sulphur humulone, particularly Acetochlor, butachlor, S-isopropyl methoxalamine and the third careless amine preferably.
The example that is fit to safener of the present invention is benoxacor, fenclorim, cloquintocetmexyl, oxabetrinil, fenchlorazole, dichlormide, separates careless amine, naphthalic anhydride, isoxadifen and mefenpyrdiethyl, particularly preferably is fenclorim, dichlormide, benoxacor, cloquintocetmexyl, separates careless amine, diphenyl methoxy menthyl acetate, isoxadifen and mefenpyrdiethyl.These compounds are known, are described in for example The Pesticide Manual, the 12nd edition, and BCPC, 2000.
The rice herbicides that can mention comprises that with the preferred compositions of safener for example Acetochlor, butachlor, the third careless amine, isopropyl methoxalamine and S-isopropyl methoxalamine combine fenclorim; Acetochlor, butachlor, the third careless amine, isopropyl methoxalamine and S-isopropyl methoxalamine are in conjunction with benoxacor; Acetochlor, butachlor, the third careless amine, isopropyl methoxalamine and S-isopropyl methoxalamine are in conjunction with cloquintocetmexyl; Acetochlor, butachlor, the third careless amine, isopropyl methoxalamine and S-isopropyl methoxalamine are in conjunction with separating careless amine; Acetochlor, butachlor, the third careless amine, isopropyl methoxalamine and S-isopropyl methoxalamine are in conjunction with the diphenyl methoxy menthyl acetate; Acetochlor, butachlor, the third careless amine, isopropyl methoxalamine and S-isopropyl methoxalamine are in conjunction with isoxadifen; Acetochlor, butachlor, the third careless amine, isopropyl methoxalamine and S-isopropyl methoxalamine are in conjunction with mefenpyrdiethyl; With Acetochlor, butachlor, the third careless amine, isopropyl methoxalamine and S-isopropyl methoxalamine in conjunction with dichlormide.
The particularly preferred combination that can mention comprises: the third careless amine is in conjunction with fenclorim; Isopropyl methoxalamine and S-isopropyl methoxalamine are in conjunction with benoxacor; Butachlor is in conjunction with the diphenyl methoxy menthyl acetate; With Acetochlor in conjunction with dichlormide.
Rice herbicides and safener may optionally be the form of acid, ester or salt, as at ThePesticide Manual, the 12nd edition (BCPC), institute mentions in 2000.
Except that become wild or the rice that degenerates, can be grassy weed such as Echinochloa and Sprangletop according to the example of the weeds of the present invention's control, broad leaved weed is like rain Pittosporum of a specified duration and cusp Pittosporum and nutgrass flatsedge such as Cyperus and genus fimbristylis.
Cultivated rice is interpreted as rice (Oryza sativa), also comprise and become rice wild or that degenerate, and those crops that become herbicide-resistant or classes of herbicides (for example ALS-, GS-, EPSPS-, PPO-and HPPD-inhibitor) by conventional breeding method or gene engineering, as (the Clearfield Rice) of anti-imidazolone type such as imazamox.
It is conventional and in for example WRRC, Tokyo-Tsukuba, 4 that the dripping of weed killer herbicide executed Th-7 Th, in November, discuss to some extent in 2004.
The used rice herbicides of the present invention can its commercial preparation form do not dilute and use.The consumption of weed killer herbicide can change in wide region, depends on the character of soil, main weather conditions and the factor of being controlled by time of application.The used weed killer herbicide of the present invention is used with the 10-5000g/ha consumption usually.
When weed killer herbicide used with safener, the latter can use separately or use with weed killer herbicide.Therefore, it is irrelevant with the time of application of weed killer herbicide in principle to realize handling cultivated rice with safener.Rice can be pretreated with safener, for example by seed dressing, for example prior to seeding.Using weed killer herbicide and safener (for example mix thing with bucket or promptly use the form of mixture) simultaneously, to handle cultivated rice be usually preferred.The consumption of safener and weed killer herbicide is 10:1 to 1:100 normally.
