The present invention relates to a combination of fungicides. More specifically, the present invention relates to fungicidal combinations comprising an azole fungicide for controlling a broad spectrum of fungal diseases.
Fungicides are an integral and important tool yielded by farmers to control diseases, as well as to improve yields and quality of the crops. There are various fungicides that have been developed over the years with many desirable attributes such as specificity, systemicity, curative and eradicant action and high activity at low use rates.
The azole fungicides are, by themselves, known for controlling fungal diseases and combating pests and weeds in the agricultural environment, and/or for preparing a fungicide useful in the treatment of seeds, foliar and/or soil diseases against attacks of pests in plants.
Fluconazole, an azole fungicide, has IUPAC name 2-(2,4-Difluorophenyl)-1,3-di(1H-1,2,4-triazol-1-yl)-2-propanol, and is represented by following structure:
Fluconazole is used to prevent and treat variety of fungal and yeast infections in humans. It belongs to a class of pharmaceutical drugs called azole antifungals. It works by stopping the growth of certain types of fungus.
Fluconazole is a first-generation triazole antifungal medication. It differs from earlier azole antifungals (such as ketoconazole) in that its structure contains a triazole ring instead of an imidazole ring. While the imidazole antifungals are mainly used topically, fluconazole and certain other triazole antifungals are preferred when systemic treatment is required because of their improved safety and predictable absorption when administered orally.
Fluconazole's spectrum of activity includes most Candida species (but not Candida krusei or Candida glabrata), Cryptococcus neoformans, some dimorphic fungi, and dermatophytes, among others.
US 20080287299 teaches use of fluconazole and other imidazole and/or triazole derivatives for controlling fungus diseases and combating pests and weeds in the agricultural environment.
The use of fluconazole in agriculture is not yet properly explored. There is elaborate knowledge on the medical use of fluconazole in humans but knowledge about use of fluconazole for agrochemical use is very limited. There is still need in the art to check for different molecules having wide spectrum activity in combatting disease on plants.
The prior art does not teach the use of fluconazole with any other fungicides, herbicides and/or insecticides.
There is still the need to create more effective means in the area of agrochemical agents for combating pests on plants.
The embodiments of the present invention are elaborated further:
Therefore, embodiments of the present invention may provide combinations of fungicides that possess an enhanced efficacy over the individual fungicides used in isolation.
Another object of the present invention is to provide a fungicidal combination that causes an enhanced greening of the crops to which it is administered.
Another object of the present invention is to provide a fungicidal combination that causes late senescence to the crop to which it is applied thereby resulting into an increasing yield of the crop.
Yet another object of the present invention is to provide a fungicidal combination that results into reduced fungal disease incidence in the crops to which it is applied.
Another object of the present invention is to provide a fungicidal combination that results into a synergistic complementation of the fungicidal efficacy of the fungicides that are co-applied.
Another objective of the present invention is to provide methods of applying said azole fungicides in combination with other agrochemically active fungicides in the control of diseases/insects/mites/nematodes and weeds, particularly foliar and/or soil diseases.
Another object of the present invention is to provide a fungicidal combination that achieves increased yield in the crops to which it is applied.
Some or all these and other objects of the invention are can be achieved by way of the invention described hereinafter.
Thus, an aspect of the present invention can provide a fungicidal combination comprising:
Another aspect of the present invention can provide fungicidal compositions comprising:
A method of controlling fungi at a locus, said method comprising applying to the locus at which said fungal control is desired, a fungicidal combination comprising:
The term ‘disease control’ as used herein denotes control and prevention of a disease. Controlling effects include all deviation from natural development, for example: killing, retardation, decrease of the fugal disease. The term ‘plants’ refers to all physical parts of a plant, including seeds, seedlings, saplings, roots, tubers, stems, stalks, foliage and fruits. The term “locus” of a plant as used herein is intended to embrace the place on which the plants are growing, where the plant propagation materials of the plants are sown or where the plant propagation materials of the plants will be placed into the soil. The term “plant propagation material” is understood to denote generative parts of a plant, such as seeds, vegetative material such as cuttings or tubers, roots, fruits, tubers, bulbs, rhizomes and parts of plants, germinated plants and young plants which are to be transplanted after germination or after emergence from the soil. These young plants may be protected before transplantation by a total or partial treatment by immersion. The term “agriculturally acceptable amount of active” refers to an amount of an active that kills or inhibits the plant disease for which control is desired, in an amount not significantly toxic to the plant being treated.
There is limited information on agricultural use of azole fungicides, particularly when used in combination with other agrochemically active fungicides. It has surprisingly been found that the addition of a multisite contact fungicide and at least a third systemic fungicide to an azole fungicide resulted in surprising and unexpected advantages. It was surprising that the addition of a multisite contact fungicide and at least a third systemic fungicide to an azole fungicide resulted in an enhancement of the efficacy, and a surprising reduction in fungal disease incidence. It has further been found that the addition of a multisite contact fungicide and at least a third systemic fungicide to an azole fungicide and application of these combinations during the flowering stage of the crop delayed the senescence in the crop to which they were applied, which led to better greening in the crop thereby increasing the level of photosynthesis occurring within the plant, thereby leading to a greater yield from the crop to which they were applied.

The composition of the present invention maybe applied simultaneously as a tank mix or a formulation or may be applied sequentially. The application may be made to the soil before emergence of the plants, either pre-planting or post-planting. The application may be made as a foliar spray at different timings during crop development, with either one or two applications early or late post-emergence.
The compositions according to the invention can be applied before or after infection of the useful plants or the propagation material thereof by the fungi.
As will be demonstrated in the examples, the addition of a dithiocarbamate fungicide to a combination of azole fungicide with the third systemic fungicide greatly improved the disease control as well as improved yield and demonstrated a synergistic effect. The lower the mixture performance in the disease control, the greater the additional benefit of the multisite contact fungicide when added to the combinations and compositions of the present invention.
The instant invention is more specifically explained by examples given above. However, it should be understood that the scope of the present invention is not limited by the examples in any manner. It will be appreciated by any person skilled in this art that the present invention includes the given examples and further can be modified and altered without departing from the novel teachings and advantages of the invention which are intended to be included within the scope of the invention.
