Abstract
Abstract WHERE R and R'' are hydrogen, hydroxy, lower alkoxy or halogen; R'''' is lower alkyl, lower alkoxy, halogen, nitro or trihalomethyl; x is 0 or a positive integer from 1 to 4 and R1, R2, and R3 are lower alkyl, with the proviso that when R and R'' are both hydrogen, x is a positive integer. A new series of 2-(poly substituted phenyl)-1,3-indandione compounds have been found to have exceptional miticidal and herbicidal activity. These compounds may be represented by the following general formula:
