Embodiment 1

[0034] Example 1: 12% tembotrione + 60% bentazone water dispersible granules (1:5)

[0035] Formula composition, taking 100 grams of samples as an example: 12 grams of tembotrione, 60 grams of bendazone, 8 grams of polycarboxylate dispersant, 5 grams of naphthalenesulfonate dispersant, 7 grams of sodium carboxymethyl starch, twelve Add 1 gram of sodium alkyl sulfate, 5 grams of ammonium sulfate, and oxidized corn starch to 100 grams.

[0036] Preparation method: Mix the above-mentioned materials and carry out airflow crushing, and then test the fineness and content after crushing, add water and mix after passing the test, then granulate and dry according to the extrusion method, and then sub-package to obtain the finished product after passing the test.

[0037] The 15% tembotrione + 55% bentazone water-dispersible granule sample prepared in this way was compared with the 48% bentazone AS and 10% tembotrione wettable powder for the control effect test. The test results are sh...

Embodiment 2

[0041] Embodiment 2: 12% tembotrione+4% bentazone oil suspension (3:1)

[0042] Formula composition, taking a 100-gram sample as an example: 12 grams of tembotrione, 4 grams of bentonite, 1.8 grams of organic bentonite, 2 grams of fumed white carbon black, 1 gram of sodium carboxymethyl starch, and 5 grams of fatty alcohol polyoxyethylene ether , 5 grams of Span 80 emulsifier, 4 grams of polyethylene glycol dioleate, 4 grams of polyethylene glycol glycerol linoleate, 2 grams of calcium dodecylbenzenesulfonate, and supplemented with soybean oil to 100 grams.

[0043] Preparation method: After mixing the above materials, carry out sand milling, grinding and inspection, after passing the inspection, sub-package to obtain the finished product.

[0044] The 12% tembotrione + 4% bentazone oil suspension sample prepared in this way, the 48% bentazone oil suspension sample and the 10% tembotrione oil suspension were subjected to drug efficacy comparison tests. The test results are sh...

Embodiment 3

[0048] Example 3: 4% tembotrione + 32% bendazone water emulsion (1:8)

[0049] Formula composition, taking 100 grams of sample as an example: 4 grams of tembotrione, 32 grams of bendazone, 5 grams of N-methylpyrrolidone, 3 grams of fatty alcohol polyoxyethylene ether, 4 grams of phenethylphenol formaldehyde resin polyoxyethylene ether gram, 3 grams of calcium dodecylbenzenesulfonate, 25 grams of C9 solvent, 5 grams of ethylene glycol, and demineralized water supplemented to 100 grams.

[0050] The 4% tembotrione + 32% bentazone water emulsion sample prepared in this way was compared with the 5% tembotrione emulsifiable concentrate and 48% bentazone oil suspension. The test results are shown in Table 3

[0051] table 3

[0052]

[0053] As can be seen from Table 3, this embodiment is at broad-leaved weeds, gramineous weeds, and the control effect of Cyperaceae is obviously better than that of a single agent, which has changed the problem that the former single agent has a po...

Abstract

The invention relates to the field of agricultural herbicides, particularly to weeding composition containing tembotrione and bentazone. The weeding composition comprises effective ingredients including the tembotrione and the bentazone, wherein the weight percentage of the effective ingredients is 8%-80%, and the weight ratio of the tembotrione to the bentazone is (30:1)-(1:30). Dosage forms such as aqueous suspending agents, oil suspending agents, suspension emulsions, emulsifiable concentrates, micro-emulsions, aqueous emulsions, wettable powder, water dispersible granules, granules and dry suspending agents can be prepared. The weeding composition is used for controlling weeds in corn fields or other places, has the characteristics that the control effect on the weeds is improved, the weeding spectrum is increased, the pesticide dosage is decreased and the like, meets the national environment protection requirements, and conforms to the national policy requirement for reduction of the pesticide dosage in the future.

Description

Technical field: [0001] The invention belongs to the application field of pesticide herbicides, and in particular relates to a herbicidal composition containing tembotrione and bendazone. Background technique: [0002] (1) Tembotrione is a triketone cornfield herbicide developed by Bayer in 2007. Its activity is higher than that of mesotrione (mesotrione, mesotrione), and it is safe for crops. [0003] CASNo: 335104-84-2 [0004] Molecular weight: 468.83 [0005] Molecular formula: C 17 h 16 CIF 3 o 6 S [0006] Structural formula: [0007] [0008] The technical product of tembotrione is a beige powder with no special smell. The pure product is solid or powder at room temperature, with a melting point of 123°C, a decomposition point of about 150°C, a relative density D20 of 1.56g / mL, and a vapor pressure of 25°C. It is 2.9x10-10hPa, and the decomposition degree in water is pKa=3.18; the solubility in water (20°C): the solubility at pH=4 is 0.22g / L, the solubility...
