Problems solved by technology

[0008] A disadvantage of existing oil dispersion formulations is that these formulations often show phase separation after storage
Therefore, even storage at ambient temperature can lead to aggregation effects, clump formation or significant settling of the suspended phase

Embodiment 1

[0094] Preparations are prepared according to the following method:

[0095] Add Solvesso 200 (heavy aromatic naphthalene), N,N-dimethyldecylamide, TSP 16EO-tristyrylphenol ethoxylate and calcium dodecylbenzenesulfonate to the vessel. Under stirring, picoxystrobin and tebuconazole were added. While stirring, the mixture was heated to 70-75°C. Keep stirring until picoxystrobin and tebuconazole are completely dissolved. Turn off heat. While stirring, the n-butanol polyglycol ether and soybean oil methyl ester were added to the vessel. Mancozeb and micronized hexamethylenetetramine were then added to the mixture. Increase the stirring rate to 800 RPM. Stirring is continued until a completely homogeneous formulation is obtained.

[0099] Preparations are prepared according to the following method:

[0100] Add Solvesso 200 (heavy aromatic naphthalene), N,N-dimethyldecylamide, TSP 16EO-tristyrylphenol ethoxylate and calcium dodecylbenzenesulfonate to the vessel. Under stirring, picoxystrobin and tebuconazole were added. While stirring, the mixture was heated to 70-75°C. Keep stirring until the pyraclostrobin and tebuconazole are completely dissolved. Turn off heat. While stirring, add n-butanol polyglycol ether, soybean oil methyl ester and TOFA to the vessel. Mancozeb and micronized hexamethylenetetramine were then added to the mixture. Increase the stirring rate to 800 RPM. Stirring is continued until a completely homogeneous formulation is obtained.

[0106] Solvesso 200 (heavy aromatic naphthalene), Tween 24, TSP 16EO-tristyrylphenol ethoxylate and calcium dodecylbenzenesulfonate were added to the vessel. Under stirring, picoxystrobin and tebuconazole were added. While stirring, the mixture was heated to 70-75°C. Keep stirring until picoxystrobin and tebuconazole are completely dissolved. Turn off heat. While stirring, the ethoxy-propoxylated alcohol, soybean oil methyl ester and TOFA were added to the vessel. Mancozeb, hexamethylenetetramine and defoamer are then added to the mixture. Increase the stirring rate to 800 RPM. Stirring is continued until a completely homogeneous formulation is obtained.

Abstract

A fungicidal oil liquid formulation comprising: a) at least one dithiocarbamate fungicide; b) at least one co-fungicide selected from the group consisting of triazole fungicides and strobilurin fungicides; and c) an agrochemically acceptable non- aqueous liquid carrier; wherein the dithiocarbamate fungicide is suspended in the liquid carrier; wherein the triazole fungicide and the strobilurin fungicide are dissolved in the liquid carrier; and wherein the liquid carrier optionally comprises an adjuvant.

Description

technical field [0001] The present invention relates to pesticidal compositions for use in agricultural pest control applications. In particular, the present invention provides a stable fungicidal oily liquid formulation comprising at least one dithiocarbamate fungicide suspended in a non-aqueous liquid carrier; at least one dithiocarbamate fungicide dissolved in a non-aqueous liquid carrier; one triazole fungicide and at least one methoxyacrylate fungicide. Background technique [0002] Dithiocarbamates are generally known to possess potent fungicidal activity. However, a particular problem with these active ingredients is their relatively high instability. This is due to the low stability of the C–S bond and the thiocarbamate functional group, especially in the presence of low pH and nucleophiles. [0003] These active ingredients can be formulated into solid formulations to improve their stability. Known solid powder formulations are, for example, Manzate 75 WG (produ...
