Abstract

Fluid fungicidal compsns. contain, by wt., (a) 20-40% iprodione (I; 1-isopropylcarbamoyl- 3-(3,5-dichlorophenyl)hydantoin) as active component; (b) an oil-in-water emulsion contg. 50-160%, on (I), of an oil with HLB 8-12, pref. 10-11; (c) 0.1-2% ethoxy-lated fatty alcohol or nonionic emulsifier and (d) opt. 0.5-2.5% neutral, hydrophilic silica. Pref. the oil can dissolved 1-5g (I) per l at room temp. and may be a mineral or vegetable oil; esp. it has viscosity 20-30 cSt. The most pref. emulsifier is derived from 13C alcohols condensed with 9-10 moles ethylene oxide and the silica is esp. hydrated pptd. silica of BET surface 200-300 sq. m. per g. (I) is esp. useful for controlling Botrytis Cinerea, particularly on vines. These formations are more effective than conventional wettable powders and are easier to handle (no formation of dust) and are less easily washed off by rain.

Description

La présente invention concerne une nouvelle composition fongicide à base d'iprodione. The present invention relates to a new fungicidal composition based on iprodione.

L'iprodione est le nom commun pour désigner un fongicide agricole connu sous la dénomination chimique
d 'isopropyl carbamoyl-l (dichloro-3,5 phényl)-3 hydantonne. Ce fongicide présente une excellente activité contre les maladies fongiques des plantes, en particulier le botrytis de la vigne.Iprodione is the common name for an agricultural fungicide known by the chemical name
of isopropyl carbamoyl-1 (3,5-dichloro-phenyl) -3 hydantonne. This fungicide has excellent activity against fungal diseases of plants, in particular vine botrytis.

Jusqu'à présent, cette matière active a été commercialisée essentiellement sous forme de poudre mouillable. Cette formulation présente l'inconvénient de la dispersion des poussières dans l'atmosphère au moment de la manipulation, soit lors de l'ensachage, soit lors de la dilution de la poudre mouillable dans l'eau lors de la préparation de la bouillie. Par ailleurs, cette formulation peut être délavée de la surface des feuilles ou des grains en cas de grosses pluies. So far, this active ingredient has been marketed mainly in the form of a wettable powder. This formulation has the disadvantage of the dispersion of dust in the atmosphere during handling, either during bagging, or during the dilution of the wettable powder in water during the preparation of the slurry. Furthermore, this formulation can be washed from the surface of the leaves or of the grains in the event of heavy rain.

La présente invention a pour but de pallier ces inconvénients. Elle a pour objet une composition fongicide agricole à base d'iprodione, caractérisée en ce qu'elle contient en poids
a - de 20 à 40 % d'une matière active à base d' iprodione,
b - une émulsion "huile dans eau" comprenant 50 à 150 % en poids par rapport à l'iprodione, d'une huile de balance hydrophile/lipophile < BHL) d'une valeur de 9 à 12 et de préférence de 10 à 11 sur l'échelle des BHL pour émulsion huile dans eau,
c - de 0,1 à 2 % d'un émulsifiant du type alcool gras éthoxylé,
d - éventuellement de 0,5 à 2,5 % d'une silice hydrophile neutre, le complément à 100 % étant constitué par de l'eau et des additifs usuels.The present invention aims to overcome these drawbacks. It relates to an agricultural fungicidal composition based on iprodione, characterized in that it contains by weight
a - from 20 to 40% of an active ingredient based on iprodione,
b - an "oil in water" emulsion comprising 50 to 150% by weight relative to iprodione, of a hydrophilic / lipophilic balance oil (BHL) with a value of 9 to 12 and preferably from 10 to 11 on the BHL scale for oil in water emulsion,
c - from 0.1 to 2% of an emulsifier of the ethoxylated fatty alcohol type,
d - optionally from 0.5 to 2.5% of a neutral hydrophilic silica, the complement to 100% consisting of water and usual additives.

Les compositions selon l'invention sont des suspensions concentrées d'iprodione dans une évulsion huile dans eau. Ces formulations fluides sont souvent appelées dans la pratique "pâtes fluides", "crèmes" ou en anglais ''flowabLes'l.  The compositions according to the invention are concentrated suspensions of iprodione in an oil-in-water evulsion. These fluid formulations are often called in practice "fluid pastes", "creams" or in English "flowabLes'l.

Dans ces compositions, la matière active est à base d'iprodione, sous forme de particules solides, dont le diamètre moyen est inférieur à 10 microns ,de preférence aves un diamètre moyen de 1 à 5 microns. In these compositions, the active material is based on iprodione, in the form of solid particles, the average diameter of which is less than 10 microns, preferably with an average diameter of 1 to 5 microns.

Dans ces suspensions, outre l'iprodione, la matiere active peut comprendre d'autres matières actives, telles que notamment le carbendazime, le bénomyl ou 7e méhylthiophanate ou un composé à base de cuivre, un éthylène bis-diWhiocarbamate métallique tel que manège, zinèbe ou mancozèbe ou un dérivé de phtalimide tel que le captane, le captafol ou le folpel. In these suspensions, in addition to iprodione, the active ingredient can comprise other active ingredients, such as in particular carbendazim, benomyl or 7th mehylthiophanate or a copper-based compound, an ethylene bis-diWhiocarbamate metal such as carousel, zinèbe or mancozeb or a phthalimide derivative such as captan, captafol or folpel.

Cependant, d'autres mélanges associant l'i prodione avec d'autres fongicides peuvent être formulés selon la présente invention. However, other mixtures combining i prodione with other fungicides can be formulated according to the present invention.

L'huile utilisable dans les compositions selon l'invention peut être de nature diverse pourvu qu'elle possède ne valeur de balance hydrophile/lipo- phile (BE dans l'échelle des BHL pour émulsion "huile dans eau';de 9 à 12et de préférence de 10 à 11 et de pré- férence d'une viscosité comprise entre 20 et 30 cst. La balance hydrophile/lipophile est définie et déterminée selon "Pesticide formulation" - Wade Van Walkenburg
Edition Marcel Dekker Inc - New York 1973.The oil which can be used in the compositions according to the invention can be of diverse nature provided that it has no hydrophilic / lipophilic balance value (BE in the BHL scale for "oil in water"emulsion; from 9 to 12 and preferably from 10 to 11 and preferably a viscosity of between 20 and 30 cst The hydrophilic / lipophilic balance is defined and determined according to "Pesticide formulation" - Wade Van Walkenburg
Edition Marcel Dekker Inc - New York 1973.

Ces huiles peuvent être minérales comme les huiles blanches d'intervalle d'ébullition compris entre 300 et 4000C, à teneur élevée en hydrocarbures paraffiniques avec, de préférence, une teneur minimale de 92 % en insulfonables. Certaines huiles végétales,de valeur de balance hydrophile/lipophile comprise dans la gamme définie ci-dessus,peuvent également être utilisées telles que, par exemple, l'huile d'arachide, l'huile de germe de mals ou l'huile de colza. These oils can be mineral like white oils with a boiling range between 300 and 4000C, with a high content of paraffinic hydrocarbons with, preferably, a minimum content of 92% of unsulfonables. Certain vegetable oils, with a hydrophilic / lipophilic balance value included in the range defined above, can also be used such as, for example, peanut oil, mals germ oil or rapeseed oil .

Un autre constituant important de la compo sition selon l'invention est un émulsifiant particulier du type alcool gras éthoxylé, condensat d'un ou plusieurs alcool gras avec de 8 à 12 oxydes d'éthylène, qui assure la stabilité de la suspension concentrée d'iprodione dans l'émulsion huile dans eau, en agissant à la fois comme dispersant-mouillant de l'iprodione et émulsionnant du système binaire "huile-eau". Another important constituent of the composition according to the invention is a particular emulsifier of the ethoxylated fatty alcohol type, condensate of one or more fatty alcohol with from 8 to 12 ethylene oxides, which ensures the stability of the concentrated suspension of iprodione in the oil-in-water emulsion, acting both as a dispersant-wetting agent for iprodione and as an emulsifier in the binary "oil-water" system.

Dans certains cas, lorsqu'on veut diminuer la quantité d'huile pour diminuer une éventuelle phytotoxicité sans nuire aux propriétés biologiques de la formulation, il peut être avantageux d'y ajouter 0,5 à 2,5 % en poids d'une silice hydrophile de préférence neutre. In certain cases, when it is desired to reduce the quantity of oil in order to reduce any phytotoxicity without harming the biological properties of the formulation, it may be advantageous to add to it 0.5 to 2.5% by weight of a silica preferably neutral hydrophilic.

Les compositions selon l'invention peuvent, en outre, contenir des adjuvants classiquescorme des agents de viscosité du type polysaccharide (en général de 0,05 a 0,1 % en poids), des dispersants fluidifiants du type polyarylphénol éthoxylé, de préférence sous forme phosphate acide ou neutralisé (en général de 0,5 à 2,5 % en poids), des antigels (en général de 5 à0 % en poids), des antimousses telles que émulsions d'huiles silicones (généralement de 0,2 à 0,6 % en poids) et agent conservateur vis-à-vis des proliférations microbiennes (en général de 0,1 à 0,2 % en poids). The compositions according to the invention may, in addition, contain conventional adjuvants such as viscosity agents of the polysaccharide type (in general from 0.05 to 0.1% by weight), thinning dispersants of the ethoxylated polyarylphenol type, preferably in the form acid or neutralized phosphate (in general from 0.5 to 2.5% by weight), antifreezes (in general from 5 to 0% by weight), antifoams such as emulsions of silicone oils (generally from 0.2 to 0 , 6% by weight) and a preservative against microbial proliferation (in general from 0.1 to 0.2% by weight).

Les compositions selon l'invention peuvent être préparées par exemple en trois étapes. The compositions according to the invention can be prepared for example in three stages.

La première consiste à préparer l'émulsion "huile dans eau" dans une cuve équipée d'une agitation vigoureuse, en coulant 1' huile dans l'eau contenant les autres additifs hydrosolubles et éventuellement 1'6mul- sifiant. The first consists in preparing the "oil in water" emulsion in a tank equipped with vigorous stirring, by pouring the oil into water containing the other water-soluble additives and optionally the emulsifier.

Dans une seconde étape, on disperse l'iprodione, en poudre fine, dans l'émulsion huileuse, toujours sous agitation. La suspension obtenue est ensuite affinée dans un broyeur, par exemple du type à billes comme le broyeur DYNO-MILL.  In a second step, the iprodione, a fine powder, is dispersed in the oily emulsion, still with stirring. The suspension obtained is then refined in a grinder, for example of the ball type such as the DYNO-MILL grinder.

Dans la troisième et dernière étane, l'agent de viscosité de type polysaccharide est dispersé dans une petite quantité d'eau contenant l'agent conservateur (formol à 40 % en solution aqueuse) et/ou la silice hydrophile neutre. In the third and last etane, the viscosity agent of polysaccharide type is dispersed in a small amount of water containing the preservative (40% formalin in aqueous solution) and / or neutral hydrophilic silica.

Les compositions huileuses d'iprodione selon l'invention présentent, outre l'avantage d'une formulation fluide, de manipulation plus aisée qu'une poudre mouillable, l'intérêt d'avoir une efficacité fongicide accrue quand elle est appliquée en traitement de pulvE- risation pour lutter contre les maladies fongiques des plantes et, en particulier, contre le botrytis (Botrytis cinerea) de la vigne, sans présenter de phytotoxicité. The oily compositions of iprodione according to the invention have, in addition to the advantage of a fluid formulation, of easier handling than a wettable powder, the advantage of having an increased fungicidal efficacy when it is applied as a spray treatment. - risation to fight against fungal diseases of plants and, in particular, against botrytis (Botrytis cinerea) of the vine, without showing phytotoxicity.

Les exemples suivants sont donnés à titre non limitatif pour illustrer les compositions selon l'invention et leurs propriétés biologiques remarquables. The following examples are given without implied limitation to illustrate the compositions according to the invention and their remarkable biological properties.

First, in a tank, the water, glycol, silicone emulsion, surfactants, including the emulsifier, are mixed. The mixture is stirred until total dispersion, then the oil is poured onto the mixture.

Ensuite, on ajoute l'iprodione, toujours sous agitation. On obtint une émulsion que l'on broye avec un broyeur DYNO-MILL pour obtenir une suspens ion concentrée d'iprodione prête à l'emploi. Then add the iprodione, still stirring. An emulsion was obtained which was ground with a DYNO-MILL mill to obtain a concentrated suspension of iprodione ready for use.

Example 5
Outdoor fungicide trials on vine botrytis.

Ces essais ont été conduits en appliquant, comparativement à dose egale à l'hectare, une poudre mouillable commerciale à 50 % d'iprodione et une cornpo- sition selon l'exemple 1, selon le programme de traitements suivant
Premier traitement
A la chute des capuchons floraux, pour assainir les pièces florales desséchées qui peuvent rester accrochées sur les grains et protéger la rafle.These tests were carried out by applying, compared to the dose equal to the hectare, a commercial wettable powder containing 50% iprodione and a composition according to Example 1, according to the following treatment program.
First treatment
At the fall of the floral caps, to sanitize the dried out floral parts which can remain hung on the grains and protect the cob.

Deuxième traitement
Avant la fermeture de la grappe, c'est-a- dire tant qu'il est encore possible à la pulvérisation d'atteindre la rafle pour la protéger cotre une attaque précoce de pourriture.Second treatment
Before the cluster closes, that is to say as long as it is still possible for the spray to reach the stalk to protect it from early attack of rot.

Troisième traitement
Au début de la véraison, c' est à partir de ce moment que les baies deviennent sensibles aux attaques du Botrytis,responsable de la pourriture grise de la vigne.Third treatment
At the beginning of veraison, it is from this moment that the berries become susceptible to attacks by Botrytis, responsible for the gray rot of the vine.

Quatrième traitement
Trois semaines environ avant la vendange pour assurer un bon état sanitaire de la récolte, à une période ou les conditions physiologiques et climatiques sont souvent très favorables au développement du champignon.Fourth treatment
About three weeks before the harvest to ensure good sanitary condition of the harvest, at a time when physiological and climatic conditions are often very favorable for the development of the fungus.

Ces traitements ont été effectués en pulvérisation pneumatique à bas volume hectare, soit de 100 à 300 1/ha1 et dirigés vers la zone des grappes (applications localisées). These treatments were carried out by pneumatic spraying at a low hectare volume, ie from 100 to 300 1 / ha1 and directed towards the cluster area (localized applications).

La contamination par le Botrytis s'est faite naturellement au cours des mois de septembre et octobre, qui ont été humides avec présence de nombreux brouillards nocturnes. Botrytis contamination occurred naturally during the months of September and October, which were humid with the presence of numerous night fogs.

A la récolte, on évalue le taux de pourriture des baies par rapport à des parcelles témoins de vignes contaminées et non traitées. At harvest, the rate of rotting of the berries is assessed in relation to control plots of contaminated and untreated vines.

Dans ces conditions, on a observé que - les parcelles de vignes témoins non traitées ont été
attaquées avec une intensité de 41 %, - la composition commerciale d'iprodione en poudre
mouillable à 50 % a une efficacité ou protection moyen
ne de 34 %, tandis que la composition selon l'exemple 1,
anpliouée à une même dose/hectare en matière active,
exerce une protection de 61 %.Under these conditions, it was observed that - the plots of untreated control vines were
attacked with an intensity of 41%, - the commercial composition of iprodione powder
wettable at 50% has an average efficiency or protection
34%, while the composition according to Example 1,
anpliouée at the same dose / hectare of active ingredient,
has 61% protection.
