Embodiment 1

[0026] Example 1: 62% penoxsulam·metozalam water dispersible granules

[0027] Weigh 60% penoxsulam, 2% mefentrazone, 4% lauryl polyoxyethylene ether, 2% sodium lignosulfonate, 1% pull-off powder BX (sodium dibutylnaphthalene sulfonate) , 1% K-12 (sodium lauryl sulfate), 3% sucrose, 0.1% dextrin, 9% talcum powder, and kaolin are added to 100% by weight. The above-mentioned raw materials are prepared through the conventional method for preparing water-dispersible granules, ie, mixing, ultrafine airflow pulverization, mixing, and granulating steps to prepare 62% penoxsulam·metsufen water-dispersible granules.

Embodiment 2

[0028] Example 2: 35% penoxsulam·mefentrazone suspension concentrate

[0029] Weigh 30% penoxsulam, 5% metenzalam, 3% sodium lignosulfonate, 4% Nongru 2201, 3% phenylethylphenol polyoxyethylene ether phosphate, 0.1% magnesium aluminum silicate , 4% ethylene glycol, 0.2% sodium benzoate, 0.4% organosilicon defoamer, and deionized water were added to 100% to prepare a 35% penoxsulam · carfentrazone suspending agent.

Embodiment 3

[0030] Example 3: 50% Penoxsulam · Metofen Wettable Powder

[0031] Weigh 5% penoxsulam, 45% carfentrazone, 5% calcium lignosulfonate, 2% pull-off powder BX, 3% sodium dodecyl sulfonate, 3% talcum powder, clay and add to 100 % parts by weight. The above raw materials are mixed and air-jet pulverized to obtain 50% penoxsulam·metsulam wettable powder.

Abstract

The invention discloses a herbicide composition containing penoxsulam and cafenstrole. The active ingredients of the herbicide composition are penoxsulam and cafenstrole in a weight ratio of 30: 1 to 1: 45. The composition disclosed by the invention is reasonable in component, the control effect is superior to the activity when each component is independently applied, and the composition has a synergistic effect; the weed control spectrum is widened and the composition which is applied once to control weeds of grass family and sedge family and broadleaf weeds in paddy fields. Meanwhile, the application frequency is reduced, the control cost is lowered, generation of the weed resistance is alleviated, and the composition is good in safety to crops and meets the safety requirements on pesticide preparations.

Description

technical field [0001] The invention relates to the technical field of herbicides, in particular to a herbicide composition containing penoxsulam and mefentrazone. technical background [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 the resistance of 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 more efficient and safe new agents to meet the control requirements. Since the creation of pesticides in my country has just started, and the varieties of pesticides with independent intellectual property rights can not meet the needs, therefore, the development of new pesticide mixed preparations is the only way for the current development of pesticides. [0003] Rice is one of the main foo...
