Abstract

Aqueous fungicidal compositions based on dithiocarbamates as active substances, which as surfactants contain a combination of ethylene oxide/propylene oxide block polymers with alkanols or arylphenols which are ethoxylated and phosphated, or their salts, have good storage stabilities and show no phytotoxic side effects.

Description

Description Aqueous, fungicidal dispersions M It is known to apply fungicides of the dithiocarbamate type alone or combined with other fungicides, such as triphenyltin derivatives, in the form of wettable powders (HP).
However, HP formulations have disadvantages in use: they frequently give off a great deal of dust and must usually be made to a paste for application.
Although aqueous dispersions of di thiocarbamates (usually combined with triphenyltin derivatives) are commercially available, they have only low storage stabilities. In addition, phytotoxic side effects are frequently observed on application of these formulations to the crop plants.
Surprisingly, it has now been found that stable formulations of dithiocarbamates or active compound combinations thereof with triphenyltin derivatives are obtained when a selected surfactant combination is used.
The present invention therefore relates to aqueous fungicidal agents based on dithiocarbamates as the active compound, wherein they contain, as surfactants, a combination of ethylene oxide/propylene oxide block polymers (type A) with ethoxylated and phosphated alkanols or arylphenols, or salts thereof (type B).
Dithiocarbamate active compounds which can be employed according to the invention are the fungicides maneb (manganese ethylenebisdithiocarbamate), mancozeb (manganese ethylenebisdithiocarbamate complex with zinc) or zineb * (zinc ethyIenebisdithiocarbamate), in particular maneb.
These active compounds are described in The Pesticide Manual, 7th edition, p. 339, 340, 564 (1983), British Crop Protection Council.
Ethylene oxide/propylene oxide block polymers (type A) which can be used are polymers having a molecular weight of 1,000 - 20,000, for example polymers of the formulae I and II below: RO-(CH_-CH~-0) -(CH-CHo-0) -R 2 2 X | 2 Z (I) where in each case x, y and z, independently of one another, denote a number from 2 to 200, and R denotes H or (C-|-Cqg)alkyl. The commercial products HOE S 3510 and HOE S 1816 from Hoechst AG may be mentioned as representatives of these polymers.
Furthermore, surfactants of type B which can be employed (R ) are surfactants of the Soprophor series: Soprophor PA (15-35), Messrs. Rhone Poulenc (= ethoxylated phos( R ) phated alkanol), Hostaphate, Messrs. Hoechst AG (= mixtures of mono-, di- and trialkyl polyglycol ether phosphates), members of the preparation 10 D 12 series, Messrs. Rhone Poulenc (= phosphated distyrylphenol oxethylate), Z p \ Soprophor FL, Messrs. RhSne Poulenc (= triethanolammonium salts of phosphated tristyryIphenol oxethyIates ).
The surfactant concentrations can vary within the following limits, relative to the total formulation: Type A: 1 - 10 Z by weight, preferably 2-7 Z by weight Type 8: 0.1 - 5 Z by weight, preferably 0.3 - 2.5 Z by weight.
The formulations according to the invention can contain as active compound combination partners for the dithiocarbamates, in particular triphenyltin derivatives, such as triphenyltin hydroxide (TPTH) or triphenyltin acetate (TPTA), preferably TPTH.
In the case of these combinations, it is expedient to use the following surfactants in addition to the type A and type B surfactants mentioned: condensation products of naphthalenesulfonic acid and formaldehyde (type C), such ( R ) as Dispersogen A (Messrs. BASF), and a mixture, in particular a 1:1 mixture of Iigninsulfonates, in particular Na Iigninsulfonate, with montmorillonite (type D), for ( R ) example Darvan No. 3 (Messrs. Vanderbilt, USA). The formulations then preferably contain 0.1 to 3 % by weight of surfactants of type C and 0.1 to 4 % by weight, in particular 0.1 - 2.0 % by weight, of surfactants of type D, besides the surfactants A and B with the abovementioned proportions by weight.
The dithiocarbamate:triphenyltin derivative ratio by weight can vary between 20:1 and 1:20, in particular between 1:20 and 10:1.
The total active compound content in the dispersions according to the invention can be 10 to 70% by weight, preferably 20 to 50% by weight.
In addition, conventional additives, for example defoamers, such as silicone defoamer SE 2 (Messrs. Wacker), antifreeze agents, such as (C2~C3)alkylene glycols, urea or glycerol, or thickeners, such as swellable alumosiIicates, polysaccharides or xanthan derivatives, can be added to the dispersions.
The aqueous, stable formulations can be prepared by adding water, the surfactant combination according to the invention and the active compound(s) to a so-called premix and then wet-grinding the mixture by means of bead and/or ball and/or colloid mills.
The invention is illustrated by the following examples, which are collated in Table I Some of the figures denote % by.weight.
