These conventionally known diphenyl ether herbicides have excellent soil treatment ability against annual gramineous weeds that generally occur in rice fields, but they have poor foliage treatment ability against various weeds or herbicidal effects against annual broad-leaved weeds and perennial weeds. They have a common characteristic of being inferior. In addition, as with other organic compounds, these derivatives differ in their chemical structure due to differences in the type, number, or position of substituents, depending on their herbicidal effect, size, slowness, or herbicidal effect on crops. In many cases, the presence or absence of drug-induced harm to other substances differs unexpectedly. The inventors have conducted various studies with the aim of obtaining industrially useful diphenyl ether derivatives that have not been previously described in literature.

その結果、一般式 (ただし、式中X,nおよびRは、前記と同じ意味を有

As a result, the general formula (wherein X, n and R have the same meanings as above) is obtained.

), and this new diphenyl ether derivative has an excellent herbicidal effect on various weeds, and is free from chemical damage to various crops, human hoarding, and toxicity to fish and shellfish. The present invention was achieved by discovering that the diphenyl ether derivative in this invention has no foreign odor.
It has the ability to spray on the soil and kill weeds before and after they emerge, which is the so-called soil treatment ability and foliage treatment ability.It is effective against a wide range of annual and perennial grass weeds and broad-leaved weeds that occur in rice fields and fields. It is effective against various weeds.

Therefore, the herbicide of the present invention is effective as an early-stage herbicide before and after rice planting in rice fields, or as a mid-stage herbicide 1 to 2 weeks after rice planting targeting perennial weeds and broad-leaved weeds, and is also effective in rice fields. It can be used as a soil treatment herbicide before and after sowing crops, or as a foliar treatment herbicide against various weeds in orchards, tea fields, mulberry fields, and non-agricultural lands. The herbicide of the present invention also has the characteristic of exhibiting extremely high herbicidal activity against weeds of the Caryophyllaceae family, which have not been able to be controlled at all by conventionally known diphenyl ether herbicides. Table 1 lists examples of novel diphenyl ether derivatives in this invention.
