The present invention relates to combinations comprising a diamide insecticide in combination with fungicidally active compounds. The said combination is highly suitable for controlling unwanted animal pests, such as insects, acaricides and/or nematodes, and unwanted phytopathogenic fungi.
An insecticide is a substance used to kill insects. They include ovicides and larvicides used against insect eggs and larvae, respectively.
Diamides insecticides are relatively new group of insecticides which includes flubendiamide, a highly potent lepidoptericide and chlorantraniliprole and its analogue cyantraniliprole. Evolution of diamides can be studied in article published Pest Manag Sci. 2013 January; 69(1):7-14.
Chlorantraniliprole and cyantraniliprole are anthranilic diamide insecticidal compounds which exhibit larvicidal activity as an orally ingested toxicant by targeting and disrupting the Ca2+ balance and ryanodine receptor. 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.
Various other classes of fungicides are also known in the art, such as Quinone outside inhibitors (QoIs), ergosterol-biosynthesis inhibitors, fungicides that act on multiple sites, fungicides that affect mitosis etc.
Dithiocarbamates are known in the art as multi-site fungicides. These fungicides are used for broad-spectrum disease control in more than 70 crops. Mancozeb is especially important for controlling devastating and fast spreading diseases such as Phytophthora infestans, Venturia inaequalis etc. Dithiocarbamate fungicides, especially mancozeb, are particularly useful for disease control because of their broad spectrum of activity, high tolerance by crop plants, and general usefulness for controlling fungal plant diseases not controlled by active compounds that act on only a single target site in the fungus.
The mixing of insecticides with fungicides results in incompatibility of physical nature and also may alter efficacy of the active ingredients. Hence, an attempt has been made to know the compatibility of fungicides with insecticides and their influence of insecticides on the bioefficacy of fungicides against cabbage leaf spot when applied as mixtures under laboratory condition.
U.S. Pat. No. 7,696,232 B2 discloses composition comprising Chlorantaniliprole and other actives which includes fungicides.
There is therefore a need in the art for combinations of anthranilamide insecticidal compounds with specific fungicides that help improve spectrum. With crop tolerances decreasing, lower use rates being imposed and resistance being increasingly observed, there is a need fora combination of actives that allows for broader disease control spectrum that combines curative and preventive actives and has a lower dosage.
Therefore, embodiments of the present invention may ameliorate one or more of the above mentioned problems:
Therefore, embodiments of the present invention may provide combinations of Insecticide and fungicides that possess an enhanced efficacy over the individual active compound used in isolation.
Another object of the present invention is to provide an insecticide and fungicides combination that causes an enhanced greening of the crops to which it is administered.
Another object of the present invention is to provide a 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 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 combination that achieves increased yield in the crops to which it is applied.
Another object of the present invention is to provide an insecticidal and fungicidal combination that causes an enhanced insecticidal activity.
Another object of the present invention is to provide a combination which enhances the protection to plants from attack or infestation by insects, acarids or nematodes.
Another object of the present invention is to provide a synergist for the anthranilamide insecticides.
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 combination comprising:
Another aspect of the present invention can provide a combination comprising:
Yet another aspect of the present invention can provide a combination comprising:
The term :disease control{hacek over ( )} 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{hacek over ( )} 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.
Surprisingly, the insecticidal and/or acaricidal and/or antimicrobial activity or the fungicidal activity and/or the plant-invigorating activity and/or the yield-enhancing II, activity of the active compound combinations according to the invention was found to be significantly higher than the sum of the activities of the individual active compounds.
It has surprisingly been found that the addition of a multi-site fungicide, preferably a dithiocarbamate fungicide, to the combinations of diamide insecticide compounds with at least another fungicide resulted in surprising and unexpected advantages. It was surprising that the addition of a multi-site fungicide to the combination of diamide insecticides with at least another fungicide resulted in an enhancement of the efficacy, and a surprising reduction in fungal disease incidence and enhanced pest control in comparison to the efficacy seen only with the combination of diamide insecticides with at least another fungicide. It has further been found that the addition of a multisite fungicide to these combinations 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.
These surprising advantages of the combinations of the invention were not observed when the multisite fungicide, preferably the dithiocarbamate fungicide, was not present in the combination. Therefore, these unexpected advantages of the combination of the present invention could be attributed to the inclusion of the multisite fungicide, preferably the dithiocarbamate fungicide, to the combination of a diamide insecticide with at least another fungicide.

As demonstrated, the mixing of multi-site fungicides with at least another fungicide and a diamide insecticidal compound greatly improved disease and insect pest control, as well as improved yield. The combination of fungicides and insecticides targeted insect and fungal pests making it an ideal combination for broad spectrum of pests and fungal diseases.
While the foregoing written description of the invention enables one of ordinary skill to make and use what is considered presently to be the best mode thereof, those of ordinary skill will understand and appreciate the existence of variations, combinations, and equivalents of the specific embodiment, method, and examples herein. The invention should therefore not be limited by the above described embodiment, method, and examples, but by all embodiments and methods within the scope and spirit of the invention.
Studies were conducted to compare the efficacy of the combination of amide insecticides with fungicides selected from the various classes and to compare their observed efficacy with the ‘expected_ efficacy when amide insecticides and fungicides were used to treat fungal and insect pests. Any difference between the observed and ‘expected_ efficacy could be attributed to synergy between the two compounds in the control of fungal and insect pests. The expected efficacy of a combination of amide insecticides with fungicides was calculated using the well-established Colby method.
In the Colby method, the expected (or predicted) response of a combination of actives is calculated by taking the product of the observed response for each individual component of the combination when applied alone divided by 100 and subtracting this value from the sum of the observed response for each component when applied alone. An unexpected enhancement in efficacy of the combination is then determined by comparing the observed response of the combination to the expected (or predicted) response as calculated from the observed response of each individual component alone. If the observed response of the combination is greater than the expected (or predicted) response, or stated conversely, if the difference between the observed and expected response is greater than zero, then the combination is said to be synergistic or unexpectedly effective. (Colby, S. R., Weeds, 1967(15), p. 20-22) The Colby method requires only a single dose of each active applied alone and the mixture of both doses. The formula used to calculate the expected efficacy (EE) which was compared with the observed efficacy (OE) to determine the efficacy of the present invention is explained hereinbelow:
EE=(B efficacy+A efficacy−(B efficacy×A efficacy)/100)
The efficacy of the individual actives of the invention and their combinations were evaluated on various fungal and insect pests. The trial was carried out in Randomized Complete Block (RCB) method, all field trials were conducted using this method. Each trial was replicated three times and conducted under GEP guidelines. Application volumes were varied for each mixture. Such field trials were carried out at various locations so as to generate independent data, the locations were chosen randomly across India. Chlorantriniprole was the amide insecticide and mancozeb and azoxystrobin were the selected fungicides which were sprayed according to their recommended dosage.
The following formula was used to calculate the expected activity of mixtures containing active ingredients, A and B:
A=observed efficacy of active ingredient (combination of bensulfuron methyl+metsulfuron methyl) A at the same concentration as used in the mixture.
B=observed efficacy of active ingredient B (third herbicide) at the same concentration as used in the mixture.
However, following formula was used to calculate the expected activity of mixtures containing three active ingredients, A, B and C:
The actives tank mix combinations, application rates, plant species tested, and results are given in the following examples:
Field trials were carried out to test the synergy of the combination of the amide insecticide chlorantriniprole, with fungicides mancozeb and azoxystrobin. The field trials were carried out at various locations in India. The percentage efficacy was calculated after 10 days of applications. The target pests were Alternaria solani in tomato and Helicoverpa armigera in tomato and the results are recorded in the table below:
In the Colby method, the expected (or predicted) response of a combination of actives is calculated by taking the product of the observed response for each individual component of the combination when applied alone divided by 100 and subtracting this value from the sum of the observed response for each component when applied alone. An unexpected enhancement in efficacy of the combination is then determined by comparing the observed response of the combination to the expected (or predicted) response as calculated from the observed response of each individual component alone. If the observed response of the combination is greater than the expected (or predicted) response, or stated conversely, if the difference between the observed and expected response is greater than zero, then the combination is said to be synergistic or unexpectedly effective.
Thus, when the combination of the present invention was analyzed using this method, it demonstrated an observed—expected value of greater than zero which is indicative of an unexpected efficacy. The basis of demonstration of unexpected efficacy by comparison with the Colby formula is that active (A) tested alone would kill a proportion of the target pests and leave the remaining portion (a %) as survivors. Similarly, active B tested alone will leave (b %) as survivors. When combined, A+B will, act independently on the target pest (if unexpected activity is absent); component A leaving a % survivors, which survivors will be controlled by component B; which has an overall effect of a %*b %*100. Subsequently, if the percent control is greater than that predicted by the Colby formula or stated conversely, if the difference between the observed control and the expected control is greater than zero; then unexpected enhancement in activity is acknowledged. The degree to which the difference is greater than zero is not itself critical as long as it is greater than zero; however greater the difference, more significant is the enhancement or the unexpectedness in control of the pest.
The results in Table 1 clearly demonstrate the synergy when chlorantriniprole was mixed with fungicides mancozeb and azoxystrobin, in the control of Alternaria solani in tomato. No phytotoxcitiy was observed and good yields were observed.
Further field trials were carried out to test the synergy of the combination amide fungicide chlorantriniprole in combination with fungicides for the control of Helicoverpa armigera in tomato. The field trials were carried out at various locations in India. The percentage efficacy was calculated after 10 days of applications and the results are recorded in the table below:
The results in tables 2 clearly demonstrate a synergy when an amide insecticide such as chlorantriniprole is combined with fungicides such as mancozeb and azoxystrobin in the control of Helicoverpa armigera in tomato. No phytotoxcitiy was observed and good yields were observed.
The instant invention is more specifically explained by above examples. 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 aforesaid examples and further can be modified and altered within the technical scope of the present invention.
