Abstract: A novel class of growth regulator compounds of the structural formula ##STR1## is disclosed, in which Y is --COOH or an agriculturally acceptable salt thereof, --COOR, --CH.sub.2 OH, --CHO, --R, --OR or halogen and R is C.sub.1 to C.sub.4 alkyl or alkenyl.

Abstract: New compounds which are herbicide antagonists that are useful for protection of plants from various herbicides are members of the group having the general structural formulas: ##STR1## in which R is hydrogen or C.sub.1 to C.sub.4 alkyl, alkenyl or alkynyl, branched or straight chain, R.sup.1 is C.sub.1 to C.sub.3 alkyl, alkenyl or alkynyl, branched or straight chain, with the total number of carbon atoms in R and R.sup.1 being less than six, preferably less than four, on compounds with both R and R.sup.1 substituents. The novel plant protection agents may be applied both to seeds and to the soil.

Abstract: Corn is protected from S-alkyl thiocarbamate herbicides, while obtaining good control of unwanted plant species by applying to the soil in the vicinity of corn seed an effective but non-phytotoxic amount of an N,N-diisopropyl, N-benzyl-N-methyl, N-benzyl-N-ethyl, N-(p-methoxybenzyl), N-methyl-N-phenethyl or N,N-diethyl amide of dichloroacetic, dibromoacetic or tribromoacetic acids.

Abstract: The activity of barban is enhanced and variation of selectivity with climatic conditions is alleviated by applying to wild oats an effective amount of a composition comprising one part by weight barban and at least four parts by weight of a polyunsaturated fatty acid exemplified by linolenic acid. The composition is preferably either dispersed in water with the aid of an emulsifier or dissolved in a mixture of water and a volatile organic solvent such as acetone.

Abstract: Crop seed, particularly corn, grain sorghum and rice are protected from injury by a variety of herbicides particularly the thiocarbamates and some amide types by coating thereon a small, non-phytotoxic amount of an N-substituted amide of a chloro or bromo alkanoic acid, preferably an N-substituted dichloroacetamide.
