Abstract

Cpds. of formula (I) are new. X is Cl, Br or F; Y is halo, CF3, trifluoromethoxy, lower alkyl, lower alkoxy, when X is Br or F; Y is lower alkyl other than methyl, or trifluoromethoxy, when X is Cl ; and m and n are each integer 1-3. (I) are prepd. by reacting 5-(2-substituted pyridyloxy) benzoic acid chloride with substituted aniline in presence of base such as triethylamine, pyridine, sodium carbonate, etc. Alternatively, (I) is prepd. by reacting 3-hydroxy-N-(substd. phenyl)-benzamide with substd. pyridyl halide in presence of base such as sodium carbonate, potassium carbonate, calcium carbonate or sodium hydroxide. (I) inhibit the germination and growth of weeds, control barnyardgrass, monochoria, slender spikerush, flatstage, etc., show no phytotoxicity to transplanted rice. (I) can be used pre- or post-emergently. Use amt. of (I) is esp. 50-500 g/10a.
