Description

TECHNICAL FIELD

[0001] The present disclosure relates to a herbicide mixture comprising pyroxasulfone, chlorotoluron and mesosulfuron-methyl. The present disclosure also relates to a herbicidal composition comprising pyroxasulfone, chlorotoluron, mesosulfuron-methyl and at least one agriculturally acceptable carrier. The present disclosure discloses methods of controlling undesirable vegetation comprising applying to the undesirable vegetation or to the locus thereof a herbicidally effective amount of the herbicide mixture or herbicidal composition disclosed herein. The present disclosure also discloses a kit comprising the herbicide mixture or herbicidal composition disclosed herein. BACKGROUND

[0002] In order to achieve high crop efficiency, control of undesirable vegetation is of utmost importance. In many cases, while a herbicide has an impact on a certain spectrum of weeds, it does not combat other species of weeds which are also present in the crop to be protected. Therefore, there is a need to combine two, three or more herbicides. In addition, the application of two, three or more herbicidal active ingredients with different modes of action can bring about a number of advantages, such as an enlarged spectrum of weeds, a reduced application rate, a reduced number of applications and, in some cases, a synergistic effect (wherein the efficacy is increased).

[0003] Compared to the use of a single herbicide, the mixture of selected multiple herbicides can also have the following advantages, including: (a) increasing the spectrum of weeds to be controlled or extending the control of weeds over a longer period of time; (b) improving crop safety, the minimum dose of the selected multiple herbicides will be applied in combination rather than a single high dose of one herbicide, and (c) delaying the emergence of resistant weed species to the selected multiple herbicides (Int. J. Agri. Biol., Vol. 6, No. 1, 2004, pp. 209-212).

[0004] However, the performance of activity and selectivity of any particular mixture is difficult to predict, as the performance of each single herbicide in the mixture is often influenced by the presence of the other herbicide(s), and the activity of the mixture can also vary significantly depending on chemical properties, plant species, growth stage, environmental conditions, and application rate, etc.

[0073] In some embodiments of this disclosure, the herbicide mixtures are synergistic, meaning that the herbicidal active ingredients are more effective when applied in combination than when applied alone. Synergy can be defined as "the interaction of two or more factors such that the combined effect is greater than the expected effect based on the individual factors applied individually" (Shaner, DL, Ed. Herbicide Handbook, 10th ed. Lawrence: Weed Society of America, 2014). In some embodiments, the herbicide mixtures exhibit synergistic effects determined by the Colby equation (Colby, SR Calculation of the synergistic and antagonistic response of herbicide combinations. Weeds 1967, 15, 20-22). The calculation of synergistic effects using the Colby equation is described in detail in the Embodiments section of this disclosure.

[0074] In one embodiment of this disclosure, the herbicide mixture may contain other active ingredients, such as other herbicides, insecticides, fungicides, bactericides, nematicides, molluscicides, growth regulators, biological agents, fertilizers, safeners, or mixtures thereof. However, to avoid confusion, it should be understood that such other active ingredients are unnecessary for achieving the desired control of unwanted vegetation by the herbicide mixture of the present invention. In further embodiments of this disclosure, the presence of other active ingredients is provided that it does not affect the synergistic effect of the herbicide mixture.

[0075] In one embodiment of this disclosure, the herbicide mixture does not contain any components other than the active ingredient, such as an agricultural carrier.

[0076] In one embodiment of this disclosure, the herbicide mixture is substantially composed of sulfonium pyrazosulfuron, chlorpyrifos, and mesosulfuron-methyl.

[0077] In one embodiment of this disclosure, the herbicide mixture consists of sulfonium pyrazosulfuron, chlorpyrifos, and mesosulfuron-methyl.

[0078] Herbicide mixtures can be applied before germination, after germination, or in combination thereof.

[0090] In some embodiments of this disclosure, the herbicidal compositions are synergistic, meaning that the herbicidal active ingredients are more effective when applied in combination than when applied alone. Synergy is defined as "the interaction of two or more factors such that the combined effect is greater than the expected effect based on the individual effects of each factor applied alone" (Shaner, DL, Ed. Herbicide Handbook, 10th ed. Lawrence: Weed Society of America, 2014). In some embodiments, the herbicidal compositions exhibit synergistic effects determined by the Colby equation (Colby. SR Calculation of the synergistic and antagonistic response of herbicide combinations. Weeds 1967, 15, 20-22). The calculation of synergistic effects using the Colby equation is described in detail in the Examples section of this disclosure.

[0091] In one embodiment of this disclosure, the weeding composition may contain other active ingredients, such as other herbicides, insecticides, fungicides, bactericides, nematicides, molluscicides, growth regulators, biological agents, fertilizers, safeners, or mixtures thereof. However, to avoid confusion, it should be understood that such other active ingredients are unnecessary for achieving the desired control of unwanted vegetation by the weeding composition of the present invention. In further embodiments of this disclosure, the presence of other active ingredients is provided that it does not affect the synergistic effect of the weeding composition.

[0092] In one embodiment of this disclosure, the active ingredients of the herbicidal composition are essentially composed of sulfonium pyrazosulfuron, chlorpyrifos, and mesosulfuron-methyl.

[0146] Example

[0147] The following embodiments are not intended to limit this disclosure, but are merely illustrative of how this disclosure is implemented.

[0148] Based on an article titled "Calculating synergistic and antagonistic responses of herbicide combinations" published by Colby SR in the journal Weeds, 1967, 15, pp. 20-22 (the full text of which is incorporated herein by reference), the theoretical value E0 of a given mixture of three active components can be predicted according to the following formula, and the presence of synergy can be assessed.

[0149] E0 = X × Y × Z ÷ 10000

[0150] In the formula:

[0151] E0 is the theoretical fresh weight survival rate of the mixture of sulfonium pyrazosulfuron, chlorpyrifos, and mesosulfuron-methyl.

[0152] X represents the measured fresh weight survival rate of sulfonylpyrazole alone when the dosage is the same as that in the mixture;

[0153] Y represents the measured fresh weight survival rate of chloromeron alone when the dosage is the same as that in the mixture;

[0154] z represents the measured fresh weight survival rate of mesosulfuron-methyl when the dosage is the same as that in the mixture.

[0155] E represents the measured fresh weight survival rate of the mixture of sulfonylpyrazole, chloromethlon, and mesosulfuron-methyl.

[0156] Calculate E0-E values ​​and evaluate the combined effects of sulfonium pyrazosulfuron, chlorpyrifos, and mesosulfuron-methyl on selected weeds.

[0157] Example 1: Soil sealing treatment with a mixture of sulfonium pyrazosulfuron, chlormequat chloride, and mesosulfuron-methyl to control jointed goatgrass.

[0158] This embodiment uses a pot experiment under glass greenhouse conditions to study the herbicidal activity of a soil-applied mixture of sulfonium pyrazosulfuron, chlormequat chloride, and mesosulfuron-methyl in controlling jointed goatgrass. This embodiment is conducted in accordance with "NY / T 1155.4-2006 Guidelines for Indoor Bioassay Testing of Pesticides - Herbicides - Part 4: Activity Assay Test - Foliar Spray Method".

[0159] Source of test reagents:

[0160] Sulfonpyrazole: Sulfonpyrazole (850g / Kg, WG) from Adama Agan Ltd.

[0161] Green Merron: Green Merron (90wt%, WG) from Adama Agan Ltd.

[0162] Methyl disulfuron: from Bayer AG, 30 g / L, OD.

[0163] Experimental location: Greenhouse, Institute of Plant Protection, Shandong Academy of Agricultural Sciences

[0164] Experimental material cultivation: The soil used in the experiment was a mixture of top 20cm loam and culture medium at a ratio of 3:1.

[0165] The experimental weeds were cultivated in a glass greenhouse at a temperature of 15-30℃ under natural light. A fixed quantity of jointed goatgrass seeds was sown in 9cm diameter plastic pots, covered with 1-2mm of soil, and placed in an enamel dish filled with water. Watering was done by bottom irrigation. After the water had soaked into the soil surface, the pots were transferred to the glass greenhouse for further cultivation. The herbicide was applied the day after sowing.

[0166] Dosage and preparation of medicine

[0167] Table 1 below gives the dosage of each drug:

[0168] Table 1:

[0169] Formulation Rate g ai / ha CK Fenclorim 90 wt% WG 180、90、45、22.5、11.25、5.625 Methyldithiophencarb 30 g / L OD 2250、1125、562.5、281.25、140.625、70.3125 Mefenpyr-diethyl 50% WG Mefenpyr-diethyl 50% WG Mefenpyr-diethyl 50% WG Mefenpyr-diethyl 50% WG Mefenpyr 40、20、10、5、2.5、1.25

[0170] For each active ingredient, Table 1 provides six doses starting from the highest dose. For each active ingredient, five lower doses are obtained from the highest dose shown using a dilution method. Measure a measured amount of the drug using a pipette or balance, add it directly to water, and dilute to the required dose using a dilution method.

[0171] Application of pesticides: Indoors, an ASS-4 type automatic control spraying system is used for pesticide spraying. The system uses fan-shaped nozzles, and the spray pressure and flow rate are adjusted according to the actual spraying area (1.1m²). 2 Spray 50mL of pesticide solution (equivalent to 30L of water per acre), adjust the operating speed, and evenly arrange the plastic basins to be treated on the spraying platform for uniform spraying. The spraying pressure is 0.35MPa, and the flow rate of the fan-shaped nozzle is 800mL / min. Spray from low to high dosage sequentially. Repeat each treatment 3 times. After spraying, allow the pesticide to dry for one day, then place it in a glass greenhouse and water it regularly to keep it moist.

[0172] Application time and frequency: The experiment was conducted on the second day after jointed wheatgrass sowing, with uniform soil spraying. The application was carried out on March 10, 2020, and was performed once.

[0173] Weed survey methods and timing: After application of the pesticide, record the symptoms of weed damage in detail (such as growth inhibition, chlorosis, deformity, etc.). After 35 days, weigh the fresh weight of the above-ground portion of the weeds in each treatment, and calculate the measured fresh weight inhibition rate and measured fresh weight survival rate for each treatment using the following formulas:

[0174] Measured fresh weight inhibition rate (%) = (Fresh herb weight of blank control treatment - Fresh herb weight of herb treated with the agent) ÷ Fresh herb weight of blank control treatment × 100

[0175] Actual fresh weight survival rate (%) = 100 - Actual fresh weight inhibition rate (%)

[0176] Example 2: Soil sealing treatment with a mixture of sulfonium pyrazosulfuron, chlorpyrifos, and mesosulfuron to control ryegrass.

[0177] Example 2 is basically the same as Example 1, except that jointed wheatgrass is replaced with ryegrass.

[0178] The experimental and calculation results of Examples 1 and 2 are shown in Table 2 below.

[0179]

[0180]

[0181] In Table 2 above, since the actual fresh weight inhibition rate of mesosulfuron at an application rate of 0.625 gai / ha was not measured, the E0-E value at that application rate could not be calculated.

[0182] Table 2 shows that the three active ingredients had poor control effects on jointed goatgrass. Sulfonazole and chlorpyrifos showed some effect, but mesosulfuron-methyl was essentially ineffective. Specifically, when sulfonazole was applied at 90 and 180 g ai / ha, the fresh weight inhibition rate of jointed goatgrass was 24.68% and 45.45%, respectively; when chlorpyrifos was applied at 1125 and 2250 g ai / ha, the fresh weight inhibition rates were 27.27% and 63.64%, respectively; while soil sealing treatment with mesosulfuron-methyl was almost ineffective, with a maximum fresh weight inhibition rate of only 28.57%. However, the combined effect of the three ingredients was significantly improved, demonstrating a strong synergistic effect.

[0183] Furthermore, as shown in Table 2, all three active ingredients have a certain effect on Lernica rubra, with sulfonium pyrazosulfuron showing the best effect, followed by the other two. The combination of the three ingredients has an even better effect, with the fresh weight inhibition rate reaching over 80% even at the lowest dose, and in particular, the E0-E values ​​reached a high synergistic result of 31.02 and 30.82.

[0184] Example 3: Soil sealing treatment with a mixture of sulfonium pyrazosulfuron, chlormequat chloride, and mesosulfuron-methyl to control jointed goatgrass.

[0185] Example 3 is basically the same as Example 1, but more compound ratios were tested.

[0186] The experimental and calculation results of Example 3 are shown in Table 3 below:

[0187] Table 3:

[0188]

[0189] As shown in Table 3, the E0-E values ​​for all tested compound ratios were greater than 0, indicating a synergistic effect. Furthermore, in the ratios of sulfonium pyrazosulfuron, chlormequat chloride, and mesosulfuron-methyl of 4.5:28.125:1, 9:112.5:1, and 36:225:1, the E0-E values ​​were all greater than 10, demonstrating a significant synergistic effect.
