Abstract
The invention relates to a coating for seeds to protect them from fungal diseases which contains an inert and acceptable in agriculture carrier and at least one active substance chosen from the group consisting of a phosphorous acid and its salts and a method for applying this coating to seeds. The coating provides a good protective effect.[BY4699C1]
Description
Fungicidal seed treatment usino- iphosohoz-ous acid or its salts The present invention relates to the protection of monocotyledon plant seeds against attacks from fungal diseases.
It is known that it is possible to control fungal diseases of plants by foliar application of phosphorous acid and its derivatives (Patent GB X,459„539> but this application has not been used in 10 practice because of the phytotoxicity of compositions containing these ingredients (European Patent Application 230^209), It has now surprisingly been found that it is possible to obtain compositions having a good protective effect on seeds, and plants resulting from the germination of these seeds, by .protecting the seeds with phosphorous acid or a derivative thereof,, without this protection being disturbed by excessive phytotoxicity.
The present invention accordingly provides seeds of monocotyledon plants comprising as fungicide from 5 to 500 g/q of phosphorous acid or a salt.thereof in the absence of 2-(4-chlorobenzylidene)-5,5-dimethyl-l-(1H1,2,4-triazol-l-ylmethyl)-l-cyclopentanol and in the absence of compounds of formula wherein R represents methyl, chloro, nitro or azido, W represents -CH (CH3) COOCH3 or in which X represents CH or N, Y represents methoxymethyl, chloromethyl, cyclopropyl, 2furyl, 2-tetrahydrofuryl, isoxazolyl or benzyl, and m represents 1 or 2, or, when R represents chloro in the meta-position relative to the amino group and at the same time w represents a butyrolactone ring, m represents 0, 1 or 2 .
As used herein, the term seeds includes any generative part (propagation material) of the plant which can be used for the reproduction of the latter. This includes not only seed grains (seeds within the narrow meaning), but also artificial seeds such as, for example, those described in Patent Applications FR 9305192 or PCT/FR 91/00984 (published under the number WO 92/10087).
The seeds may be natural or artificial seeds of monocotyledon plants.
The presence of another fungicide is not necessary, and in particular the triasole 2-(4chlorobenzylidene)~5,5~fii»efchyl-’3.-{lH-l,2,4-fcriaz0X-X~ ylmethyl) -X-cyclopentanol (the use of whxch with a second fungicide which aiay be inter alia phosphorous acid or a phosphite salt is described in European specification No. 467792) is not used, but the presence of other fungicides is optional as described below.
Phosphorous acid, also known as phosphonic acid, has the formula H-p(o$ 2 (.abbreviated as H3PO3J . Its salts are known as phosphites, and can be Mono- or dxsalts, preferably alkali metal or ammomwa salts, in particular Na2HPO3„ K2SPO3 or NH4H2PO3.
On a practical level, the effective amount of phosphorous acid or salt thereof is generally between 5 and 500 g/q (q is the abbreviation of quintal = 100 kg).
The seed grains comprise a proportion of 5 to 5 500 g of active material per quintal of seed grain and preferably 5 to 300 g/quintal, preferably applied by coating.
The active material of phosphorous type is preferably chosen such that its solubility in water at 20’C is greater than 0.1 g/1, more preferentially still greater than 0.,5 g/1 and more preferentially still greater than 50 g/l„ Active materials-of lower solubility can also be used but it is then necessary to use fairly complicated formulations, for example wettable powders IS or aqueous suspensions. The use of active materials of sufficiently high solubility as it has just been defined is advantageous in that it makes it possible to treat seeds using simple solutions,, which is extremely economic.
The invention further provides young plants resulting from the germination of the seeds which have just been defined, these young plants being at the one- or twoleaf stage.
That such young plants are obtained is all 25 the more remarkable since it could be expected that the residual phosphorous acid has a phytotoxic effect with respect to plants resulting from the germination, in the same way that it had a phytotoxic effect in foliar treatment.
