2-arylaminopyrimidinone derivative, and herbicide and plant growth

Disclosed herein is a process for producing a sulfoneamide represented by the following formula (6) as an intermediate of a 6-haloalkyl-3-phenyluracil derivative, from as a starting material 4-halogeno-3-nitroaniline (9) or 2-halogeno-5-nitroaniline (10): ##STR1## (wherein X and Y independently represent a halogen atom, R represents a C.sub.1 -C.sub.4 alkyl group or a C.sub.1 -C.sub.3 haloalkyl group and R' represents a C.sub.1 -C.sub.4 alkyl group or a phenyl group).

Aniline derivatives and process for producing the same

Uracil derivatives

Disclosed herein is uracil derivatives having a trifluoromethyl group at the 6-position and a phenyl group at the 3-position which has a NHSO.sub.2 D.sup.26 group at 5-position of the benzene ring, halogen atom at 4-position thereof and hydrogen atom or halogen atom at 2-position thereof, which are represented by the formula (I) and showing penetrative translocation activity, a very high herbicidal activity and, particularly, no phytotoxicity against soybean, in which as compared with the conventional herbicidal compounds, the said uracil derivatives can be applied for either soil treatment or soil incorporation treatment, thereby producing a quick and high herbicidal effect even at a very low dosage against a large variety of weeds including perennial weeds, and have the property to residual effect for an appropriate period of time.

Uracil derivatives and herbicides containing the same as active

Disclosed herein is uracil derivatives having a haloalkyl group at the 5-position and a phenyl group at the 2-position which has a specific substituent, which are represented by the formula (I) and showing penetrative translocation activity and a very high herbicidal activity, in which as compared with the conventional herbicidal compounds, the said uracil derivatives can be applied for either soil treatment or foliage treatment, thereby producing a quick and high herbicidal effect even at a very low dosage against a large variety of weeds including perennial weeds, and have the property to residual effect for an appropriate period of time.

The present invention provides novel uracil derivatives and pesticides which contain the novel uracil derivatives as an active ingredient, and exhibit preventing and controlling effects against harmful living things, especially agricultural insect pests, sanitary insect pests, stored product insect pests, house insect pests and veterinary insect pests at a very low drug-concentration.
