The present invention relates to compounds which can be used to control plant development. Indeed, the present invention discloses a new class of pyrabactin analogues which have a physiological effect onfor exampleseed germination, and/or stomatal closure, and/or have developmental effects on root and shoot development and organogenesis. Hence, the latter compounds can be used to control plant development such asfor exampleincreasing the tolerance of plants to drought stress or to control physiological phenomena such as pre-harvest sprouting, tolerance to pathogens etc.

A first aspect of the invention is an agricultural composition comprising nanoparticles, an agrochemical active ingredient in the nanoparticles, and optionally (but in some embodiments preferably) a carrier for the nanoparticles. In some embodiments, the nanoparticles are viral particles or capsids, particularly plant viral particles or capsids. In some embodiments, the carrier comprises an inert or biodegradable carrier (e.g., a solid carrier) to which the nanoparticles are bound or in which the nanoparticles are suspended. In some embodiments, the carrier comprises inert or biodegradable polymer fibers.
