Abstract: A method for preventing or reducing resistance to a pesticide of a substrate pest, which method comprises the administration to the substrate or the pest of a composition comprising: (a) a rapid-release formulation of an inhibitor of a factor causing or contributing to the resistance of the pest to the pesticide; and, substantially simultaneously, (b) a non-rapid release formulation of the pesticide. The invention also provides compositions suitable for use in such a method.

Abstract: This invention relates to uses of waste products obtained when biodiesel is generated for reducing nitrate leaching from soil.

Abstract: cis-Jasmone has been discovered to be useful as a semiochemical that changes the behavior of insects and/or the physiology of plants. It has direct signalling roles with plant-feeding aphids, in attraction of aphid predators and parasitoids, and may act as an airborne signal inducing production of volatile plant semiochemicals, including the monoterpene (E)-?-ocimene, that stimulate foraging by parasitoids. It is an extremely benign compound having, to human beings, a pleasant aroma and gives a long-lasting effect after removal of the stimulus.

Abstract: A nucleic acid sequence is provided which encodes a gibberellin 2-oxidase gene which catalyses the 2?-oxidation of a gibberellin molecule to introduce a hydroxyl group at C-2 and further catalyses the oxidation of the hydroxyl group introduced at C-2 to yield the ketone derivative. Such sequences can find application in the preparation of transgenic plants with altered levels of gibberellin 2-oxidase.

Abstract: The present disclosure is relative to a method for the production of Very-Long-Chain Fatty Acids (VLCFA) into a plant cell, including culturing a recombinant plant cell in an appropriate medium, wherein said plant cell is transformed with an heterologous gene encoding for an hydroxyacyl-CoA dehydratase. The disclosure is also relative to a method for producing vegetable oil including high levels of VLCFA.

Abstract: A method is provided for increasing the weight of plant seed, which comprises preparing a genetically modified plant in which gibberellin content has been manipulated in the seed of the plant.
