The uracils with herbicidal activity do not necessarily contain 5-halo substituents. 3-Cyclohexyl-5-methyluracil [354] (XLIV), l,3-di-isopropyl-6-methyl-uracil [352] (XLV) and 3-s-butyl-5-thiocyanato-6-methyluracil [353] (XLVI), for example, are cited as having this type of activity. 3-Butyl-6-methyluracil (XLlllc) possesses interesting selective activities. For instance, this pyrimidine kills many annual weed species without damage to peas and peanuts, even when applied at twice the concentration needed to kill the weeds [346]. On the other hand, the related 5-bromo derivatives, such as (XLlIlb), are useful as industrial herbicides where it is desirable to kill all plants [346].
