Description
(54) FUNGICIDE
(71) We, BASF AKTIENGESELLSCHAFT, a German Joint Stock Company of 6700
Ludwigshafen, Federal Republic of Germany, do hereby declare the invention, for which we pray that a Patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following Statement:
The present invention relates to a fungicide containing a composition of active ingredients.
It is known to use N-tridecyl-2,6-dimethylmorpholine (German 1,164,152) and 1-(4-chlorophenoxy)-3,3-dimethyl- 1-(1 ,2,4-triaxol- 1-yl)-2-butanone (German Laid-Open
Application DOS 2,201,063) as fungicides. When used for combatting rusts and/or mildews in cereals, N-tridecyl-2, 6-dimethylmorpholine has the disadvantage that its action is insufficiently persistent, and by contrast 1-(4-chlorophenoxy)-3, 3-dimethyl-1-(1,2,4- triazol-1yl)-2-butanone has to be used prophylactically to be sufficiently effective.
We have now found that a fungicide comprising N-tridecyl-2,6-dimethylmorpholine and 1-(4-chlorophenoxy)-3,3-dimethyl-1-(1,2,4-triazol-1-yl)-2-butanone has an excellent curative fungicidal action, and is much more effective than its components used individually.
The fungicide according to the invention is especially suitable for combatting plant diseases caused by mildews or rusts in, for instance, cereals, e.g. Erysiphe graminis in wheat and barley, or Puccinia species in wheat and barley, e.g. Puccinia hordei, Puccinia recondita and
Puccinia striiformis.
The fungicide may be prepared in conventional manner by mixing the active ingredients and subsequently adding solid or liquid carriers, e.g. water or organic liquids, and with or without surfactants. The fungicide contains, for example, from 0.1 to 95wt% of active ingredient composition. The ratio of the active ingredients to each other may vary over a wide range. A weight ratio of N-tridecyl-2, 6-dimethylmorpholine to 1-(4-chlorophenoxy)-3, 3-dimethyl-1-(1, 2,4-triazol-1-yl)- 2-butanone of from 4:1 to 2:1 is preferred.
When used for treating plants, the fungicides according to the invention are usually applied at rates of from 0.3 to 3 kg. of composition per hectare.
The following examples demonstrate the superior action of the new fungicide.
The degree of effectiveness was determined using Abbot's formula:
Degree of % attack in control - % attack in expt. x 100 effectiveness % - % attack in control
EXAMPLE 1
Winter wheat of the "Topfit" variety was sown in October. At the beginning of the following July, 10% of the surface area of the glumes and flag leaves of the wheat plants was covered with the mildew Erysiphe graminis var. tritici. The plants were uniformly sprayed with an aqueous suspension of an active ingredient composition of N-tridecyl-2, 6-dimethylmorpholine and 1-(4-chlorophenoxy)-3, 3-dimethyl-1-(1,2,4- triazol-1-yl)-2- butanone. For comparison purposes, the individual components of the composition were applied in the same manner. After 15 days, the mildew had spread to such a great extent on the leaves of the untreated control plants that it was possible to assess the curative action of the agents.

EXAMPLE 2
Winter wheat of the "Diplomat" variety was sown in October. At the end of the following
June, 15 % of the surface area of the glumes and flag leaves of the wheat plants was covered with mildew. The plants were treated in the same manner as disclosed in Example 1. The curative action of the fungicides was determined after three weeks.

Leaves of barley plants of the "Asse" variety grown in pots were artificially infected with urediospores of the rust fungus Puccinia hordei, and the plants were placed for 24 hours in a chamber having a high humidity. The plants were then placed in the open; 6 days after having been infected, the plants were treated with the active ingredient combination and the individual components thereof. After a further 5 days the untreated control plants exhibited strong rust attack (rust pustules). The extent of fungus spread (curative action) is assessed as follows: 0 = no attack, graduated down to 5 = 100% attack
