Description
6 C 41 3 la - Case 130-3996 IHPROVEHEHTS IH OR RELATING TO FUNGICIDES The present invention relates to fungicides.
The invention provides a method of combatting fungal diseases in plants, with the aid of a) the compound of formula I hereinafter referred to by its common name "prochloraz".
Compound A is a known fungicide, effective in the combatting of fungi in crops such as cereals including rice, especially in wheat and barley; it has excellent activity against rusts (such as Puccinia spp.) and good activity against powdery mildews (such as Ervsipheh Septoria and Rhizoctonia. Prochloraz is a known fungicide having good activity against Pseudoeercosporella, Septoria, Pyrenophora9 powdery mildews and Pyricularia.
It has now been found that the use of prochloraz in combination with Compound A is surprisingly effective in the combatting of fungi. The combination is particularly suitable for full season use against foot diseases, leaf diseases and ear diseases, particularly foot diseases in cereals.
Accordingly, the invention provides an improved method of combatting fungal diseases in plants, especially in cereals (including rice), which particularly in wheat and barley, comprises applying to the plants, in admixture or separately, Compound A and prochlorgz in an effective aggregate amount. The method shows an excellent plant tolerance. More than additive effect is i.a. observed against Septoria in wheat and Helminthosporium in barley. hereinafter referred to as "Compound A", and b) the compound of formula II II -2~ 130-3996 Suitable application rates are 50 to 100 g, particularly 60 to 80 g of Compound A per hectare and 250 to 500 g, particularly 300 to 450 g of prochloraz per hectare of crop locus. The weight ratio of Compound A : prochloraz preferably lies in the range of 1 : 2 to 1 : 8, more preferably of 1 : 3.5 to 1 : 8. particularly of 1 : 3.75 to 1 : 6.
Examples of suitable weight ratios of Compound A : prochloraz are 1 : 3.75, 1 : 5 and 1 : 7.5. The compounds are preferably applied in spray form employing in general an application volume of from 0.05 to 0.5 hi per hectare, e.g. from 0.05 to 0.1 hi for airial application and from 0.2 to 0.4 hi for conventional ground application.
The invention also provides a fungicidal composition comprising Compound A and prochloraz, preferably in the weight ratio as defined above.
The composition of the invention may be formulated in any conventional form, for example in the form of a twin packet, or of an emu!sifiable concentrate, wettable powder or water dispersibie granule, the emulsifiable concentrate form being preferred. Such compositions may be produced in conventional manner,, e.g. by mixing Compound A and prochloraz with appropriate adjuvants such as diluents and optionally other formulating ingredients such as surfactants.
The term diluent as used herein means any liquid or solid agriculturally acceptable material - including carriers - which may be added to the active constituents to bring them in an easier or improved applicable form, respectively, to a usable or desirable strength of activity. It can for example be talc, kaolin, diatomaceous earth, xylene, or water.
Particularly formulations to be applied in spraying forms such as water dispersibie concentrates or wettable powders my contain surfactants such as wetting and dispersing agents» e.g. the condensation product of formaldehyde with naphthalene sulphonate, an alkylarylsulphonate, a lignin sulphonate, a fatty alkyl sulphate, an ethoxylated alkylphenol and an ethoxylated fatty alcohol.
In general, the formulations include from 0.01 to 90% by weight of active agent, from 0 to 20% agriculturally acceptable surfactant and 10 to 99.99 % solid or liquid adjuvant(s), the active agent consisting of the Compound A, prochloraz and optionally other active agents. -3- 130-3996 Concentrate forms of compositions generally contain between about 2 and 80 %, preferably between about 5 and 70 % by weight of active agent. Application forms of formulation may for example contain from 0.01 to 45% by weight. 5 The invention is illustrated by the following examples, wherein parts and percentages are by weight.
Emulsi fi able Concentrates Composition A B Compound A techn. (95.5%) 6,2 8.2 10 Prochloraz techn. (97.4%) 29.7 29.7 Emulsified1} 15.0 15.0 Sol vent(2) 49.1 47.1 Total 100 100 (1) e.g. a mixture of 7 parts of a mixture of oxyethylated triglyceride with 15 branched calcium alkyl aryl sulphonate in iso-butanol and 8 parts of tributyl phenol polyglycol ether. (2) e.g. a mixture of 15 parts propyleneglycol monomethylether and 34.1 parts (for Composition A) or 32.1 parts (for Composition B) of xylene.
