The present invention relates to an algae composition in the form of an aqueous suspension. More specifically, the present invention relates to an aqueous suspension composition, wherein the aqueous suspension composition is green algae, red algae, golden algae, brown algae in the range of 0.1% by weight to 65% by weight. (Brown algae), golden-brown algae, blue algae, blue-green algae or one or more algae selected from their species, 0.1 wt% The composition comprises 0.1 to 60% by weight of one or more surfactants in the range of ~ 50% by weight and one or more structuring agents in the range of 0.01% by weight to 5% by weight. Has a particle size range of. Furthermore, the present invention relates to the process of preparing an algae composition comprising at least one algae and at least one agrochemically acceptable excipient in the form of an aqueous suspension. The present invention further relates to methods of treating plants, seeds, seedlings, crops, plant growth materials, their locations, parts thereof or soil using algae compositions in the form of aqueous suspensions.本発明は、水性懸濁液の形態の藻類組成物に関する。より具体的には、本発明は、水性懸濁組成物に関し、水性懸濁組成物は、0.1重量%~65重量%の範囲の緑藻類、紅藻類、黄金藻類(golden algae)、褐藻類(brown algae)、黄金褐藻類(golden-brown algae)、藍藻類(blue algae)、藍緑藻類(blue-green algae)またはそれらの種から選択された1または複数の藻類と、0.1重量%~50重量%の範囲の1または複数の界面活性剤と、0.01重量%~5重量%の範囲の1または複数の構造化剤とを含み、組成物は、0.1ミクロンから60ミクロンの粒径範囲を有する。更に、本発明は、水性懸濁液の形態の、少なくとも1つの藻類と、少なくとも1つの農芸化学的に許容される賦形剤とを含む藻類組成物を調製するプロセスに関する。本発明は更に、水性懸濁液の形態の藻類組成物を用いて、植物、種子、苗木、作物、植物増殖材料、それらの場所、それらの一部または土壌を処理する方法に関する。
