These compounds are active as plant growth regulators, and particularly as chemical hybridization agents.

Abstract: A biologically active agent-containing composition is prepared by reacting an aqueous emulsion or dispersion of a suitable biologically active agent and an optional filler in an aqueous solution or gel of a polyhydroxy polymer and an inorganic salt, with a boric acid or boric acid derivative until an insolubilized matrix phase is formed having entrapped therein uniformly dispersed, discontinuous domains of said agent and an optional aqueous phase that can be separated from the matrix phase by decanting, filtration, or the like; the product is then dried and ground to the desired particle size. The composition is applied to the soil or plants where the biologically active agent is slow released for controlling pests.

Abstract: S-(Aminoalkyl)isothioureas which have immunosuppressant activity. Two specific compounds are 2-(3-dimethylaminopropylthio)-2-imidazoline and N,N'-dimethyl-S-(3-dimethylaminopropyl)isothiourea.

Abstract: Compositions comprising a non-phytotoxic antidotal compound and an antidotable herbicide and the use of the compositions to protect crop plants from injury due to the herbicide.

Abstract: Herbicidal agents containing an active substance of the formula (I) ##STR1## in which R denotes alkyl, in combination with an active substance of the formula (II) ##STR2## in which R.sub.1 denotes phenyl, which is substituted by chlorine or (C.sub.1 -C.sub.3)-alkyl, or denotes benzothiazolyl, R.sub.2 denotes H or methyl and R.sub.3 denotes H, methyl or methoxy, show super-additive actions and are outstandingly suitable for combating harmful plants in cereals.

Abstract: The subject invention concerns a novel bioherbicide and its use to control a major weed found in many fields in the Southeastern United States where peanuts and soybeans are grown. Specifically, Colletotrichum truncatum (Schw.) Andrus & Moore, in an agricultural composition, can be used to effectively control Florida beggarweed without adversely affecting field crops, e.g., peanuts and soybeans. Further, C. truncatum (Schw.) Andrus & Moore in a mixture with Alternaria cassiae can be used to control Florida beggarweed and other undesired vegetation, such as sicklepod, showy crotalaria and coffee senna.

Abstract: N-Aryl benzamides wherein the aryl group is a nitrogen containing heterocycle are useful as selective herbicidal agents. Compositions containing the novel benzamides and a herbicidal method of selective weed control are disclosed.

Abstract: The invention relates to N-phosphonomethylglycylhydroxamic acid of the formula I ##STR1## or of the tautomeric formula Ia ##STR2## and salts thereof with strong acids, organic nitrogen bases, alkali metal or alkaline earth metal ions, as well as complex salts with aluminium or heavy metal compounds. These compounds have herbicidal and plant growth-regulating properties.

Abstract: A method of crop seed treatment is disclosed which provides an increase in the yield of seedlings emerging from the treated seeds in soil and stimulates growth of the seedlings. The method comprises coating the seeds prior to planting with an aqueous suspension of a water-insoluble alkali lignin containing minor amounts of at least one surfactant wherein the lignin has a mean particle size from 0.5 to 5 microns in diameter.

Abstract: A known antibiotic, SF-1293 substance and salts thereof have now been found to exhibit high herbicidal effects against a wide variety of herbaceous and woody plants, but they are non-phytotoxic particularly to a useful woody plant, Chamaecyparis obtusa. The herbicidal effects of these SF-1293 substances can be synergistically enhanced by applying in combination with herbicides selected from Linuron, Monolinuron, Monuron and Diuron each known as herbicides of urea derivative class.

Abstract: Pollen suppressants of the formula ##STR1## wherein Z represents a divalent organic radical of the formula --CH.dbd.CH--CH.dbd.CH--, --CH.dbd.CH--CH.dbd.N--, --CH.dbd.CH--N.dbd.CH--, --CH.dbd.CH--NH--, --CH.dbd.CH--O--, or --CH.dbd.CH--S-- or said radical in which an H of Z is replaced with a halogen atom with the proviso that no more than three H or Z are replaced by fluorine; a C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 alkoxy, C.sub.1 -C.sub.4 alkanoyl, cyano, nitro, hydroxy, or trihalomethyl group; or a group of the formula --NR.sup.1 R.sup.2 wherein R.sup.1 and R.sup.2 independently represent a hydrogen atom or a C.sub.1 -C.sub.4 alkyl group; Y is Y.sup.1 R.sup.3 or NR.sup.4 R.sup.5 wherein Y.sup.1 is oxygen or sulfur; R.sup.3 is hydrogen, C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 alkoxyalkyl, cyclohexylmethyl, halogenated C.sub.1 -C.sub.4 alkyl, phenyl, or benzyl; and R.sup.4 and R.sup.5 are independently selected from the group consisting of hydrogen, C.sub.1 -C.sub.4 alkyl, or C.sub.1 -C.sub.
