The present invention relates to compositions of natural origin for use in agricultural crops (vegetables and fruit trees), particularly for use in biostimulant formulations and/or with antimicrobial action, which allow crops to be protected from stress, improving the quality and yield of plants and/or their fruits.

The invention provides a biostimulant and/or antimicrobial composition comprising extracts made from plants that include berry leaves rich in polyphenols, flavonoids, and micronutrients. In a preferred embodiment of the invention, the composition comprises extracts made from blueberry leaves. A process for making said composition is also provided.

The present invention deals with the formation of Natural Organic Nano-Fertilizers with the chelated nano-nutrients to balance plant nutrition; improve water holding capacity, soil health improvement, sustainable productivity and quality improvement. The present invention involves production of eco-friendly and low cost process for the synthesis of nanoparticles of nano-nutrients by utilizing microorganisms comprising of two lab adapted strains of Aspergillus species, one lab adapted strain of Lactobacillus sp. and lactate, gluconate and proteinate salts as a source of nutrient leads to formation of metal nanoparticles (Zn, Mg, Fe and P) with the size of <20 nms. The present invention increases 12-20% of crop yield, stress tolerance of the crops, nutrient mobilization increases and 3 fold increase in nutrient use efficiency.

The strigolactone receptor inhibitor for plants contains at least one kind of triazole urea compounds represented by the following formula (I) as an active ingredient. It can be applicable to an agricultural composition; a method for using the agricultural composition as, for example, a branching enhancer for plants; a germination inhibitor for Striga seeds, the germination inhibitor containing the triazole urea compound; and a novel triazole urea compound that is useful as a strigolactone receptor inhibitor for plants. In the formula, A represents a group represented by (A-1) or (A-2). R.sup.1 and R.sup.2 represent a hydrogen atom and so forth. R.sup.3 and R.sup.4 represent a hydrogen atom, an alkyl group having 1 to 20 carbon atoms, a cycloalkyl group having 3 to 20 carbon atoms, or an aryl group having 6 to 20 carbon atoms and so forth. R.sup.3 and R.sup.4 may form a ring together.
