Embodiment 1

[0024] Example 1: Preparation of 16% diflufenican-difenpyr suspension concentrate (weight ratio: 1:15)

[0025] Diflufenican 1%, Difenpyr 15%, Nonylphenol Polyoxyethylene Ether Phosphate 8%, Xanthan Gum 1%, Bentonite 1%, Glycerin 3%, water to 100%;

[0026] Each component was weighed according to the above ratio, pre-pulverized according to the proportion, then added to a sand mill for grinding, and mixed by high shear to prepare a 16% diflufenican-difenpyr-acryl suspension concentrate.

Embodiment 2

[0027] Example 2: Preparation of 22% diflufenican-difenpyr wettable powder (weight ratio: 1:10)

[0028] Diflufenamide 2%, Difenpyr 20%, Calcium Lignosulfonate 5%, Tripolyphosphoric acid 3%, NNO 8%, Talc 7%, Kaolin supplemented to 100%;

[0029] Weigh each component according to the above ratio, coarsely pulverize the solid component and send it to the mixer together with other components to mix evenly, and then air-jet pulverize to obtain 22% diflufenican·difenfen Nitrile wettable powder.

Embodiment 3

[0030] Example 3: Preparation of 38.5% diflufenican·difenpyr water-dispersible granules (weight ratio: 10:1)

[0031] Diflufenamide 35%, Difenpyr 3.5%, Clay powder 3%, Bentonite 4%, Sodium Lauryl Sulfate 7%, Polycarboxylate 5%, Kaolin to 100%;

[0032] Each component was weighed according to the above ratio, dry crushed, granulated, dried, and sieved according to the proportion to prepare 38.5% diflufenican·difenpyr water-dispersible granules.

Abstract

The invention provides a weeding composition containing diflufenican and pyraclonil. The weeding composition comprises the following active ingredients: diflufenican and pyraclonil, wherein a weight ratio of the diflufenican to the pyraclonil is 1:15 to 15:1. The weeding composition disclosed by the invention is used for controlling annual gramineous weeds such as barnyard grass, leptochloa chinensis and the like and one part of cyperaceous weeds and broadleaf weeds. Pharmacodynamic tests prove that the weed control effect is improved by utilizing complementarity between the active ingredients of the composition, the defect of a herbicide in single use is overcome, and the weeding composition has an obvious synergistic effect and long lasting period and is safe to rice crops.

Description

technical field [0001] The invention belongs to the field of agricultural plant protection. More specifically, the present invention relates to herbicidal compositions containing diflufenican and dipacenil. Background technique [0002] Rice is one of the most important food crops in my country. There are many types of weeds in paddy fields, and the types of weeds are different in different regions. There are more than 200 kinds of weeds in the rice areas of the country. Among them, the common and serious weeds are about There are 50 species, and the main weeds include barnyardgrass, sedge, bermudagrass, and daughters. Weeds in rice fields will affect the growth of rice and thus affect the yield of rice. Up to now, many herbicides suitable for weed control in rice fields have been developed. However, there are many kinds of weeds in paddy fields with different characteristics. A single herbicide is often unable to kill a variety of weeds at the same time due to its limited...
