Effective plant growth regulation is obtained by the application of 3-thiabicyclo(3.2.0)heptane-6,7-dicarboxylic anhydride 3,3-dioxide to plants.

Novel 3,5-dimethyl-2-thienylcarboxanilides and 3,5-dimethyl-2-thienyl-(N-haloalkylthiocarboxanilides) are active pre- and post-emergent herbicides.

The harvest of fruit from bearing trees and plants is facilitated by application of effective concentrations of 4,5-dibromothiophene-2-carboxylic acid.

This invention relates to a method for controlling the growth of undesired vegetation in paddy rice crops by applying an effective amount of an oxabicycloalkane herbicidal compound to the locus of paddy rice.

The present invention is directed to novel compounds of the formula ##EQU1## which compounds are useful as herbicides. In the above and succeeding formulae herein, R.sup.1 represents hydrogen or R.sup.2, and each R.sup.2 independently represents loweralkyl of C.sub.1 -C.sub.4, loweralkenyl of C.sub.3 -C.sub.4, loweralkynyl of C.sub.3 -C.sub.4, or radical of the formula --CH.sub.2 --CH.sub.2 --CH.sub.2 --.sub.n Y wherein n represents 0 or 1, and Y represents methoxy, cyano, bromo, or chloro, subj...

The present invention relates to a novel triketone derivative having a specific structure and a herbicide containing the triketone derivative as an active ingredient. The herbicide is effective for controlling weeds which inhibit growth of crop plants, inter alia, for paddy weeds such as Sanwa millet and Scirups juncoides.

Novel 2-(N,N-dialkylamino)-3,5-dinitrothiophenes have bactericidal, fungicidal and herbicidal activity.

Certain novel N-sulfamoyl-2-thiophenecarboxamides are effective herbicides especially well suited for the control of nutsedge in the presence of valuable crops. A representative herbicidal compound within the above scope is N-(tert-butylsulfamoyl)-2-thiophenecarboxamide. BACKGROUND OF THE INVENTION This invention relates to novel N-(substituted sulfamoyl)-2 -thiophenecarboxamides and to their use as selective germination inhibitors of certain plant species, especially of nutsedge. While many her...

A radio frequency transfer switch is provided which includes a pair of spaced apart annular fixed contact elements and a pair of movable contact discs carried by an axially reciprocable shaft which is fluid motor actuated to move the contact discs into and out of engagement with the fixed annular contacts. The fixed annular contacts are supported by plate means and fluid cooling tube means are disposed against the plate means and in surrounding relationship with respect to the fixed annular cont...

The present invention relates to novel aryl-substituted S(O).sub.m cycles of the formula (I): ##STR1## in which F.sup.1, F.sup.2, G, V, W, X, Y, Z and m are each as defined in the description, to processes for their preparation and to their use in agriculture, for example as crop protection agents (fungicides, herbicides and insecticides).
