Abstract: Curable compositions essentially comprise a selected class of starting compounds and a selected class of particulate metallic oxides as electrically conductive components, the oxides being coated with a selected class of hydrolyzed silicon compounds of the formulaR.sub.m.sup.1 R.sub.n.sup.2 Si(OR.sup.3).sub.4-(m+n)where R.sup.1 and R.sup.2 each are a hydrocarbon moiety of 1 to 20 carbon atoms or an organic group containing a halogen atom or an epoxy, acrylonitrile, methacrylonitrile, mercapto or amino group, each of the hydrocarbon moiety and organic group forming a Si-C bond, R.sup.3 is a hydrocarbon moiety of 1 to 6 carbon atoms or an oxygen-containing hydrocarbon moiety, m and n each are 0, 1 or 2, and the sum of m and n is 1 or 2. The resulting cured coating excels in transparency, abrasion resistance, adhesive strength and electrical conductivity.

Abstract: A method of increasing the harvest of a crop which comprises applying an effective amount of taurine to the crop or its seeds, and a composition therefor.

Abstract: A plant growth regulating composition comprising as an active ingredient a combination of(a) at least one gibberellin-type plant hormone, and(b) at least one compound selected from compounds of the general formula ##STR1## wherein R represents a C.sub.1 -C.sub.5 alkyl, C.sub.2 -C.sub.5 alkenyl, C.sub.2 -C.sub.5 alkynyl, C.sub.1 -C.sub.5 haloalkyl or benzyl group,and agriculturally acceptable salts thereof.

Abstract: New compound, designated as leucanicidin, is now provided and is useful as insecticide. Leucanicidin is fermentatively produced by a microorganism Streptomyces halstedii No. 3002-14 (identifiable as FERM BP-493).

Abstract: A compound of the formula ##STR1## wherein Y represents a halogen atom, a lower alkyl group, a lower alkoxy group or a trifluoromethyl group and R represents a lower alkyl group. This compound can be produced by reacting a compound of the formula ##STR2## or a reactive derivative thereof with an aniline derivative of the formula ##STR3## and is useful as a herbicide.

Abstract: A plant growth regulator comprising, as its active component, one or more compounds selected from the group consisting of [+]-hexylitaconic acid, and the dihydro derivative and lower alkyl monoesters thereof is effective for growth regulation of plants.

Abstract: A herbicidal composition containing as an active ingredient a compound of the formula ##STR1## wherein R.sub.0 represents a hydrogen atom or a lower alkyl group, and R.sub.1, R.sub.2 and R.sub.3 each represent a hydrogen or halogen atom, or a lower alkyl, lower alkoxy or lower alkenyloxy group, which is especially useful for application to aquatic rice paddies, and novel compounds of formula (I) wherein R.sub.0, R.sub.1, R.sub.2 and R.sub.3 have the same meanings as defined above, provided that R.sub.1, R.sub.2 and R.sub.3 do not represent hydrogen atom at the same time.
