Abstract

An aqueous suspension concentrate (SC) composition of a crop protection active compound is provided, the concentrate comprising: (a) 50 to 700 g / l of an active ingredient comprising at least one compound active in crop protection; and (b) a concentrate stabilising component consisting of: (i) up to 150 g / l of at least one non-ionic dispersing agent; and / or (ii) to 150 g / l of at least one anionic dispersing agent; and 10 (c) 200 to 800 g / l of water; with the proviso that in the case that the suspension concentrate comprises an active ingredient other than an azole and the concentrate stabilising component consists of an anionic dispersing agent only, the anionic dispersing agent is present in an amount of greater than 30 g / l; or in the case that the suspension concentrate comprises an azole derivative as the active ingredient and the concentrate stabilising component consists of both an anionic dispersing agent and a non-ionic dispersing agent, the anionic dispersing agent is present in an amount of greater than 30 g / l. The suspension concentrate is particularly useful in the formulation of fungicides, in particular azole derivates of the given formula (I), especially tebuconazole.

Description

Technical field [0001] The present invention relates to agrochemical compositions, in particular aqueous suspension concentrates of compounds having crop protection activity. The invention relates in particular to these compositions containing one or more compounds having fungicidal activity. The invention also relates to a method for preparing the above composition and its use in crop protection. Background technique [0002] In general, the inert components of the formulation must be matched to introduce crop protection active compounds, such as fungicidal compounds, into formulations that allow the user to use them as such or after dilution with water. The correct selection of the inert ingredients suitable for use in the formulation often determines to a large extent whether the active ingredient will exert its full effect after application. When selecting appropriate ingredients to ensure the physicochemical stability of a formulation, it must be considered that not e...
