Abstract: Compounds which are useful as selective herbicides have the general structural formula ##STR1## in which R.sup.1 and R.sup.2 are selected from hydrogen, and lower alkyl, alkenyl, alkylene and alkoxy structures and together possess a total of 1 to 6 carbon atoms when R.sup.3 is ethyl, propyl, isopropyl, cyclopropyl, methoxy or tert-butyl.

Abstract: Weeds are selectively controlled in soybean fields by post-emergent application of a compound having the structural formula ##STR1## in which X represents bromo, fluoro, cyano or trifluoromethyl and R is hydrogen or methyl.

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: A canister for an explosive primer containing capsensitive aqueous gel explosive is formed from a thermoplastic by blow-molding a pair of semi-cylindrical bottles connected by an integral hinge which have one or more corresponding grooves in their mating flat longitudinal surfaces. When the flat surfaces of the two containers are placed in contact and the containers are fastened together to form a cylinder, the matching grooves form a central longitudinal tubular passage through the canister and, if desired, one or more cylindrical wells in close proximity to the central passage.

Abstract: A class of 3-benzyl-2-methylimino-5-phenyl-.DELTA..sup.4 -1,3,4-thiadiazolines which may have certain specific substituents on the benzyl and phenyl rings are useful in combating various weeds in grain crops, for example, grassy weeds in wheat and rice fields.

Abstract: Compounds which are useful as selective herbicides have the general structural formula ##STR1## in which R.sup.1 and R.sup.2 are selected from hydrogen, and lower alkyl, alkenyl, alkylene and alkoxy structures and together possess a total of 1 to 6 carbon atoms when R.sup.3 is ethyl, propyl, isopropyl, cyclopropyl, methoxy or tert-butyl.

Abstract: Chloro and dichloro tert.butyl-1,3,4-thiadiazole-di- and trimethylurea compounds are extraordinarily phytotoxic compounds which are particularly useful for non-selectively combating unwanted vegetation.

Abstract: Undesired vegetation, including crabgrass, Johnson grass and pigweed are effectively controlled in cotton, corn and peanuts in the warm temperate zones by application of an effective amount of 1,3-dimethyl-1-(5-tert.butyl-1,3,4-thiadiazol-2-yl)urea or the corresponding 1-ethyl-3-methyl compound to the locus of the weeds. A particularly desirable procedure is the use of one of the new herbicides in combination with alachlor to give very broad spectrum weed control, including such noxious weeds as nutsedge.

Abstract: Barban (4-chloro-2-butynyl m-chlorocarbanilate) is formulated as liquid emulsifiable concentrates containing as much as twenty to thirty percent of the herbicide which have improved efficacy and unlike other formulations of higher concentration, are also safe to use in wheat fields. A particularly critical component of the improved concentrate is a condensation product of C.sub.12 to C.sub.18 fatty alcohols with from ten to forty units of ethylene oxide.

Abstract: Insects and mites are combated by applying to the locus of insects in at least one stage of the insects' life cycle an effective amount of a compound having the structural formula ##STR1## in which X and X' may be oxygen or sulfur, R may be alkyl, cycloalkyl, aryl, alkenyl, alkynyl, optionally substituted with halogen, hydroxy, alkoxy, nitro, mercapto or alkylthio substituents, R' may be hydrogen, alkyl, cycloalkyl, alkenyl, alkynyl, aryl etc., and if R' is not hydrogen one of R" and R"' may be hydrogen while one or both may be alkyl, optionally substituted with halogen, hydroxy, alkoxy, mercapto or alkylthio substituents or R" and R"' together may be part of a heterocyclic ring containing 2 to 6 carbon atoms, with the provision that the total of R, R', R" and R"', must contain from 4 to 9 carbon atoms and if R is straight chain alkyl having less than 6 carbon atoms, none of R', R" and R"' may be hydrogen. The novel insecticides are particularly useful in combating aphids.

The novel insecticides are particularly useful in combating aphids.

Abstract: Broadleaf weeds, including sicklepod are selectively controlled in soybean fields by applying post-emergently to the plant foliage one of a restricted class of 5-chlorobenzylthio-1,3,4-thiadiazolylurea compounds, for example, 1,1,3-trimethyl-3-(5-p-chlorobenzylthio-1,3,4-thiadiazol-2-yl)urea.

Abstract: Wild oats are killed over a substantial period of growth from two-leaf through four-leaf stages by applying post-emergently to the oats plants an effective amount of a combination of one part of barban with from about two to five parts, preferably three to four parts of CIPC, a herbicide which is normally applied pre-emergently.

Abstract: Insects of the orders Coleoptera and Orthoptera are selectively killed in the presence of living plants by applying to the locus of the insects an effective amount of 1-N,N-dimethylcarbamyl-3-tert.butyl-5-methylthio-1,2,4-triazole.

Abstract: Mites and insects, particularly aphids, are combated by applying as pest control agents one or more compounds of the structural formula ##STR1## in which R is tert.butylphenyl; tert.butyl; 3,5-dimethylphenyl; 1-methyl-1-phenylthioethyl; 1-methyl-1-methylthioethyl; 1-cyclohexylthio-1-methylethyl; 1-cyclohexylthiopropyl; 1-ethylthio-1-methylethyl; 1-ethylthiopropyl or 1-ethylthioethyl.

Abstract: In the quarrying of wet, poorly consolidated rock in which blasting charges are placed with the aid of a removable metal casing to prevent collapse of the walls of the boreholes, improved results are obtained by placing cardboard tubing inside the removable metal casing with internal bushings reinforcing the tubing joints instead of using external collars or connectors.

Abstract: Triazolylsulfonamides of a limited class are substantially non-phytotoxic and are useful as insecticides. For example 1-N,N-dimethylcarbamyl-3-tert.butyl-1,2,4-triazol-5-yl-N,N-dimethylsulfona mide is effective in aphid control, both by foliar application and systemically.

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.

Abstract: Insects are combated selectively in the presence of other forms of animal life by applying to the locus of the insects an effective amount of 2,3-dihydro-2,2-dimethyl-7-benzo[b]thienyl N-methylcarbamate, a compound with less mammalian toxicity than closely related carbamate insecticides.
