Embodiment 1

[0030] Example 1: Toxicity determination of fenpyramid, mefentrazone and their mixtures on rice barnyardgrass at the 3-leaf stage.

[0031] Table 1 Dose-response regression relationship of mefentram and mefentram and their mixtures on rice barnyardgrass at the 3-leaf stage

[0032]

[0033] See figure 1 , the isobologram of the synergistic effect of the mixture of fenpyramid and mefentrazone on rice barnyardgrass at the 3-leaf stage ( figure 1 The drawing refers to NY / T1155.7-2006, and the drawing data comes from Table 1)

[0034] Depend on figure 1 It can be concluded that the equivalence points of the mixture of fenpyramid and mefentrazone to the 3-leaf stage barnyard rice are all below the theoretical isobolism, showing a synergistic effect.

Embodiment 2

[0035]Example 2: 30% oxafluzamide · mefentrazone water-dispersible granules.

[0036] Methazone

[0037] Add the above-mentioned streams into the conical mixer and mix them evenly, and then pulverize them through the jet mill, and then mix the pulverized materials through the conical mixer. Synthesize the plastic material, put the material into the extruding granulator to extrude and granulate, after granulation, dry and sieve to obtain 30% oxentrafen·metsufen water dispersible granule.

Embodiment 3

[0038] Example 3: 30% oxazone-metofen wettable powder.

[0039] Methazone

[0040] Add the above materials together into a conical mixer and mix them evenly, then crush them through a jet mill, and then mix the pulverized materials through a conical mixer. The fineness of the mixed materials is 98% and passes through a 600-mesh standard sieve to obtain 30% mefentrazone-mefentrazone wettable powder.

Abstract

The invention relates to herbicide composition containing effective ingredients including metamifop and cafenstrole in the weight ratio being (15:1)-(1:15) and used for a rice paddy field. The herbicide composition acts on annual and perennial grassy weeds including barnyard grass, crab grass, eleusine indica or reed in the rice paddy field, on annual and perennial cyperaceae weeds including Scirpus juncoides Roxb, Eleocharis yokoscensis or Cyperus rotundus in the rice paddy field and also on annual and perennial broadleaf weeds including false loosestrife, sagittaria pusilla, Rotala indica or monochoria vaginalis in the rice paddy field. The herbicide composition has a remarkable synergistic effect, the control effect of the composition is improved to a certain degree while compared with that of a single agent, the use dosage of pesticides is reduced, and the pesticide use cost and the impact risk of the pesticides to the ecological environment are reduced.

Description

technical field [0001] The invention belongs to the technical field of pesticides, in particular to the field of herbicides, and in particular relates to a paddy field herbicidal composition containing mefentrazone and mefentrazone as active ingredients. Background technique [0002] With the phase-out of highly toxic pesticides, new pesticides with high efficiency, low toxicity, safety, and environmental friendliness are needed. At the same time, the long-term use of pesticides has resulted in resistance to pests and weeds, and the requirements for control chemicals are getting higher and higher. It is necessary for pesticide research and development personnel to develop efficient and safe new agents to meet the control requirements. Since the development of pesticides in my country has just started, and the varieties of pesticides with independent intellectual property rights can not meet the needs, the development of new pesticide mixed preparations is the only way for th...
