Description
Technical field
The present invention relates to a kind of Herbicidal combinations, particularly relate to a kind of binary built, be applied to the Herbicidal combinations in Semen Maydis field.
Background technology
In plant husbandry, preventing and treating suppression plant growth to cause weeds that yield reduces and cover crop be critically important.In order to reduce the loss caused due to the weeds in arable farming, as growth difference or crop yield reduce, have now been developed that some can effectively prevent and treat described weeds and the herbicidal active component to crop safety.Up to the present, there is the herbicide developed in a large number registered and for preventing and treating the weeds of some crop.Sufficiently high activity of weeding and a broad herbicidal spectrum should be had for preventing and treating the herbicide of the weeds in specific arable farming, and response environment and crop safe enough.But, not every herbicide can fully meet above-mentioned requirements.
Most-often used increase activity of weeding is that two or more have the herbicidal active compounds mixing of different activity of weeding with the method for the herbicidal spectrum widening existing herbicide.If mixing two or more herbicidal active compounds, the herbicide action outstanding than single herbicide application may be demonstrated.So, when the effect of the mixture of two or more composition is more than the expection effort levels of each composition, we term it " potentiation ".But, present in the Herbicidal mixture of the two or multiple herbicidal active compounds, potentiation is the most visible.Due to the difference of the aspects such as herbicidal performance, absorbance, transfer, metabolism, the activity of weeding of most of mixture is singly executed less than each composition." antagonism " represents the such situation i.e. herbicide action of the mixture of two or more herbicidal active compounds singly executing less than each composition." addition " represents that the such situation i.e. herbicide action of the mixture of two or more herbicidal active compounds is identical with singly executing of each composition.
Benzene flumetsulam (Saflufenacil); No. CAS is 372137-35-4; chemical name is: N'-[the fluoro-5-of the chloro-4-of 2-(1; 2; 3; 6-tetrahydrochysene-3-methyl-2,6-dioxy-4-trifluoromethyl pyrimidine-1-base) benzoyl]-N-isopropyl-N-methylsulfonamides, its molecular structural formula is:

Preventive effect to barnyard grass (Echinochloa crusgalli)
Semen Euphorbiae (Leptochloachinensis), Herba stellariae mediae (Stellaria media), Amaranthus retroflexus (Amaranthus are prevented and kill off in the combination of benzene flumetsulam and azoles oxadiazon
Retroflexus), Herba Setariae Viridis (Setaria viridis), volume stem knotweed (Fallopia (ex Polygonum) Convolvulus), barnyard grass (Echinochloa crusgalli), Herba Abutili (Abuthilon
Theophrasti), Semen Maydis (Corn), Sagittaria trifolia L. Var. Angusti-folia(Sieb.) Kitag.(Sagittaria sagittifolia L.) (Sagittariatrifolia), Rhizoma Alismatis (Oriental Waterplantain Rhizome), Herba monochoriae vaginalis (Herb of Pygmy Arrowhead), Monochoria korsakowii (Monochoria
Korsakowii), Lindernia procumbens (Krock.) Phillcox. (Lindernia procumbens), firefly Lin (Scirpus juncoides Roxb), Herba Cyperi Difformis (Cyperus
Difformis L.) demonstrate obvious potentiation.In the case of the Herbicidal combinations using the present invention, it exceedes in the present composition summation of independent herbicide action when contained each herbicides compounds is individually sprayed to the herbicide action of weeds.Therefore, execute with each herbicides compounds list compared with, the compositions of the present invention can provide same weeds herbicide action under the relatively low consumption of herbicides compounds.The reduction of this activity of weeding and the increase of effect and active component consumption has convincingly demonstrated the potentiation of the present invention.
Increase the evaluation of crop safety
Crop safety is stated by term " crop plants toxicity ", and this represents infringement to crop, therefore means that the safety to crop is higher to the phytotoxicity degree of crop is relatively low.The crop plants toxicity of the Herbicidal combinations of the present invention is less than the summation of crop plants toxicity when each herbicides compounds contained by compositions individually sprays.Therefore, the compositions of the present invention has crop safety more higher than the compositions containing single herbicidal active component, and the crop plants toxicity therefore occurred when single component is used significantly reduces, it is sufficient to for target crop.The increase of described safety can be calculated by above-mentioned Colby ' s method.If it is observed that the actual crop plants toxicity (%) of mixture less than according to the calculated desired value of Colby method (E), this means that mixture has the phytotoxicity lower than the summation of each composition, i.e. compositions and has potentiation security effectiveness.
Security effectiveness to Semen Maydis
The crop safety of the Herbicidal combinations of the present invention is higher than the summation of crop safety when each herbicides compounds contained by compositions individually sprays.
