Benzoylprop-ethyl (31) and flamprop-isopropyl (32), two anilide herbicides selective in cereals with specific efficiency for the control of wild oat Avena spp.), have been developed in the research latoratories of the Shell Research Ltd. 

Benzoylprop-ethyl is a postemergence wild oat herbicide selective in wheat, while the chemically closely related flamprop-isopropyl, isopropyl N-benzoyl-N-(3-chloro-4-fluorophenyl)-DL-alaninate (WL 29762, 32) is a wild oat herbicide selective in barley. 

The herbicidal properties of flamprop-isopropyl were first described in 1974 (Mouillac et a .. 1974 Warley et al., 1974 Haddock et al.. 1974). The excellent wild oat killing properties of benzoylprop-ethyl could not be utilised in barley, because it occasionally causes considerable phytotoxic injuries, and hence a decrease in yield. Since the investigation of the mode of action and of the metabolism of benzoylprop-ethyl showed that the free acid is the carrier of the herbicidal action, it stood to reason that there might be a compound among those of closely related structure, which was selective also in other cereal species. 

Screening tests showed that of this series of compounds isopropyl ( ) 2-[N-(3-chloro-4-fluorophenyl)benzamido]propionate, flamprop-isopropyl, possesses the desired biological properties. The optimal application rate and time of application were subsequently determined by field experiments in several countries. 

Flamprop-isopropyl is used postemergence at a rate of 1 kg active ingredient/ha in barley in the period between tillering and the appearance of the first node. Control of over 90% of all of the Avena spp. can thus be attained. Barley tolerates twice this dose without phytotoxic injury. For the efficient control of wild oat the vigorous competition of the crop is needed (Jelfcoat and Harris, 1973). 

Activity and selectivity of flamprop-isopropyl are similar to those of benzoylprop-ethyl. Flamprop-isopropyl too becomes active as the free acid ( flamprop ) after deesterification. The acid is rapidly translocated in the phloem to the growth sites of the plant cell. The rate of translocation is five times that for benzoylprop-ethyl. The growth of wild oat is stunted by the inhibition of cell elongation. 

Flamprop-isopropyl is not toxic to mammals, its acute oral ld, for rats being 3000 mg/kg, for mice 2SS4 mg/kg. It is of moderate to low toxicity to fish. 

Haddock et al. (1974) described, along with flamprop-isopropyl, another compound, flamprop-methyl ester, code number WL 29761, which is selective in wheat (Mataven ). WL 29 761 gives a higher yield in wheat than benzoylprop-ethyl, and is also effective against Alopecuruspratensis (Chow, 1974 Gompf, 1974). Scott et al. (1976) reported on the preparation and biological activity of the levorotatory optical isomer of flamprop-isopropyl, known by its code number WL 43 425. 

The provisional trade name of the herbicide with WL 43 425 active substance is Super Bamon . It is a 20% emulsifiable concentrate. WL 43 425 is prepared from flamprop-isopropyl by resolution. Flamprop-isopropyl is hydrolysed to the acid... 

Levorotatory flamprop-isopropyl is twice as efficient for the control of wild oat (Avena spp.) as the racemate, and under poor culture conditions this difference is considerably larger. WL 43 425 is also selective in wheat, though somewhat less active than racemic flamprop-methyl.
