1,164,564. Treating grain and seeds. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. 20 June, 1968 [21 Aug., 1967], No. 38435/67. Addition to 1,123,487. Heading A2Q. [Also in Divisions A5, C1 and 2] Plant-growth regulant compositions comprising at least one 5-(1,2-epoxy-cyclohexyl)-2, 4-dienoic acid derivative of the general formula: wherein R 1 , R 2 and R 3 are each a hydrogen atom or an alkyl group, R 4 and R- are each a hydrogen atom or an optionally halogenated alkyl group; R 6 is a hydroxyol, alkoxy, aryloxy or alkylamino group, or a cylic amino group of the formula NR 7 R 8 in which R 7 and R 8 , together with the nitrogen atom to which they are attached, form a ring system which is optionally further substituted and may contain further hetro atoms; and X is a hydrogen atom or an alkoxy group; in association with a carrier, a surface-active agent, or both a carrier and a surface-active agent, are used to inhibit germination or as herbicides by application thereof to roots, seeds, e.g. cereal seeds, bulbs, corms, rhizomes or tubers before planting. Many conventional carriers, such as inert solid and liquid carriers, and surface-active agents are exemplified. The compositions may also contain protective colloids, sodium polyphosphates, cellulose ethers, stabilisers, stickers and other plant-growth regulant substances. They may be applied as wettable powders, dusts, granules, solutions, emulsifiable concentrates, emulsions or pastes. |
