- Panama disease is an aggressive plant disease of the roots of banana plants caused by the fungal pathogen Fusarium oxysporum, in particular Fusarium oxysporum f.sp.cubense (Foe), race 1 and race 4. It is the most destructive disease in bananas. E.g. during the 1950s, Panama disease wiped out most commercial Gros Michel banana production, the at this time leading banana variety. Today new strains of Panama disease threaten again the production of today's most popular cultivar, the Cavendish type.
- the Fusarium fungus enters the plant's roots and spreads through the plant's xylem vessels.
- the fungus disrupts the plant's vascular system, which causes the leaves to turn yellow and wilt, and the plant dies sooner or later.
- the pathogen affects banana crops worldwide with so far 4 races. It's “Race 1” has spread to the Philippines, and Indonesia, where nowadays the even more aggressive "Tropical Race 4" is spreading already. "Race 1" is on the rise in Africa and Australia as well. It has yet to arrive in Latin America, but it is only a question of time when Panama disease is also devastating banana plantations in this region. This causes tremendous financial damage and endangers the existence of the related banana farmers.
- Isotianil derivatives are described for controlling microbial and animal pathogens in plants of the Musaceae family, exemplified only by Black Sigatoka (Mycosphaerella fijiensis). It has now been found that Isotianil and mixtures of Isotianil with at least one further active ingredient are particularly suitable for controlling Panama disease on plants of the Musaceae family.

- Isotianil may, if appropriate, be present in the form of mixtures of various isomeric forms which are possible, in particular stereoisomers, such as optical isomers. Isotianil can therefore be employed for protecting plants against attack or delaying the attack/symptoms by the abovementioned pathogens within a certain post-treatment period.
- the period within which protection is afforded generally extends from 1 to 30 days, preferably 1 to 14 days, after the treatment of the plants with the active substances.
- the accessibility of the active substances to the plant can be controlled in a targeted manner.
- the good plant tolerance of Isotianil at the concentrations required for controlling plant diseases according to the present invention permits a treatment of aerial and subterranean plant parts, of vegetative propagation material, and of the soil.
- plants of the Musaceae family may be treated.
- Plants of the Musaceae family are, in the present context, understood as meaning all plant parts and plant populations, such as desired and undesired wild plants or crop plants (including naturally occurring crop plants).
- Crop plants may be plants of the Musaceae family which can be obtained by traditional breeding and optimization methods or else by biotechnological and recombinant methods, or combinations of these methods, including the transgenic plants of the Musaceae family and including the plant varieties capable or not of being protected by Plant Breeders' Rights, such as, for example, Gros Michel, Cavendish, Dwarf Cavendish, Dwarf Chinese, Enano, Caturra, Giant Cavendish, Gran Enano, Grande Naine, Williams Hybrid, Valery, Robusta, Poyo, Lacatan, Pisang masak hijau, Monte cristo, Bout rond.

- Plant parts are intended to mean all aerial and subterranean parts and organs of the plants, such as herb, pseudostem, shoot, leaf, bract, leaf sheaths, petiole, lamina, flower and root, examples which may be mentioned being leaves, needles, stalks, stems, flowers, fruiting bodies, fruit, banana hand, bunches and seeds, and also roots, tubers, rhizomes, offshoots, suckers, secondary growth.
- the plant parts also include crop material and vegetative and generative propagation material, for example cuttings, tubers, rhizomes, slips and seeds.
- all plants of the Musaceae family can be treated in accordance with the invention.
- plant species and plant varieties, and their parts which are found in the wild or which are obtained by conventional biological breeding methods, such as hybridization, meristem cultures, micropropagation, somatic embryogenesis, direct organogenesis or protoplast fusion, are treated.
- transgenic plants of the Musaceae family and plant varieties of the Musaceae family which have been obtained by recombinant methods, if appropriate in combination with traditional methods (genetically modified organisms), are treated, such as, for example, transformation by means of Agrobacterium or particle bombardment of embryogenic cells, and micropropagation.
- Plants of the Musaceae family include all plant parts as mentioned above.
- plants of the Musaceae family of those plant varieties which are in each case commercially available or in use are understood as meaning plants with new properties ("traits") which have been obtained by conventional breeding, by mutagenesis or else by recombinant DNA techniques. They may be varieties, breeds, biotypes and genotypes.
- plants of the Musaceae family treated according to the present invention as described above are varieties of Gros Michel, Cavendish and Dwarf Cavendish, preferably of Cavendish.
- the treatment method according to the invention can be used for the treatment of genetically modified organisms (GMOs), for example plants or seeds.
- GMOs genetically modified organisms
- Genetically modified plants are plants in which a heterologous gene has been integrated stably into the genome.
- heterologous gene refers to a gene which is provided or assembled outside the plant and which, upon introduction into the nuclear genome, the chloroplast genome or the mitochondrial genome of the transformed plant, confers novel or improved agronomical or other properties by expressing a protein or polypeptide of interest, or by downregulating or switching off another gene, or other genes, present in the plant (for example by means of antisense technology, cosuppression technology or RNAi technology [RNA interference]).
- a heterologous gene which is present in the genome is also referred to as a transgene.
- a transgene which is defined by its specific presence in the plant genome is referred to as transformation event, or transgenic event.
- the treatment according to the invention may also result in superadditive ("synergistic") effects.
- the following effects are possible, which extend beyond the effects which are actually to be expected: reduced application rates and/or a widened spectrum of action and/or an increased efficacy of the active substances and compositions which can be employed in accordance with the invention, better plant growth, increased tolerance to high or low temperatures, increased tolerance to drought or water or soil salinity, improved flowering performance, easier harvesting, accelerated maturation, higher yields, larger fruit, greater plant height, more intensive green colour of the leaf, earlier flowering, better quality and/or higher nutritional value of the harvested crops, higher sugar concentration in the fruits, better storability and/or processability of the harvested crops.
- Isotianil can also exert a strengthening effect on plants. They are therefore suitable for mobilizing the plant defence system against attack by microbial and animal pathogens. This may be one of the reasons for the increased efficacy of the combinations according to the invention, for example against fungi.
- Plant-strengthening (resistance-inducing) substances in the present context are also to be understood as meaning those substances or substance combinations which are capable of stimulating the plant defence system such that the treated plants, when subsequently inoculated with microbial and animal pathogens, have a considerable degree of resistance to these microbial and animal pathogens.
- the substances according to the invention can therefore be employed for protecting plants against attack by the abovementioned pathogens within a certain post-treatment period.
- Plants and plant varieties of the Musaceae family which are preferably treated in accordance with the invention include all plants which contain hereditary material which confers especially advantageous, useful traits to these plants (no matter whether this has been achieved by breeding and/or biotechnology).
- Plants and plant varieties of the Musaceae family which are also preferably treated in accordance with the invention are resistant to one or more biotic stress factors, i.e. these plants have an improved defence against animal and microbial pathogens such as nematodes, insects, mites, phytopathogenic fungi, bacteria, viruses and/or viroids.
- microbial pathogens such as nematodes, insects, mites, phytopathogenic fungi, bacteria, viruses and/or viroids.
- Musaceae which are resistant to phytopathogenic fungi or viruses.
- Plants and plant varieties of the Musaceae family which can also be treated in accordance with the invention are those plants which are resistant to one or more abiotic stress factors.
- the abiotic stress conditions may include for example drought, low-temperature and high-temperature conditions, osmotic stress, water-logging, increased soil salinity, increased exposure to minerals, ozone conditions, intensive light conditions, limited availability of nitrogen nutrients, limited availability of phosphorus nutrients, or shade avoidance.
- Plants and plant varieties of the Musaceae family which can also be treated in accordance with the invention are those plants in which vaccines or therapeutic proteins are expressed heterologously. These include, for example, hepatitis B antigen.
- Plants and plant varieties of the Musaceae family which can also be treated in accordance with the invention are those plants which are characterized by improved yield characteristics.
- an increased yield may be caused by, for example, improved plant physiology, improved plant growth and improved plant development, such as water utilization efficacy, water holding efficacy, improved nitrogen utilization, increased carbon assimilation, improved photosynthesis, improved seed vigour, and accelerated maturation.
- the yield may furthermore be influenced by improved plant architecture (under stress and nonstress conditions), among which early flowering, control of flowering for the production of hybrid seed, seedling vigour, plant size, internode number and distance, root growth, seed size, fruit size, pod size, pod number or ear number, number of seeds per pod or ear, seed biomass, increased seed filling, reduced seed shedding, reduced pod shatter, and standing power.
- Further yield-related traits include seed composition such as carbohydrate content, protein content, oil content and oil composition, nutritional value, reduction of antinutritional compounds, improved processability and improved storability.
- Plants of the Musaceae family that may be treated according to the invention are hybrid plants that already express the characteristics of heterosis or hybrid vigour which results generally in higher yield, vigour, health and resistance towards biotic and abiotic stress factors. Such plants are typically made by crossing an inbred male-sterile parent line (the female parent) with another inbred male- fertile parent line (the male parent). Hybrid seed is typically harvested from the male-sterile plants and sold to growers. Male-sterile plants can sometimes (e.g. in corn) be produced by detasseling (i.e. the mechanical removal of the male reproductive organs or male flowers) but, more typically, male sterility is the result of genetic determinants in the plant genome.
- detasseling i.e. the mechanical removal of the male reproductive organs or male flowers
- male fertility in hybrid plants that contain the genetic determinants responsible for male sterility is fully restored. This can be accomplished by ensuring that the male parents have appropriate fertility restorer genes which are capable of restoring the male fertility in hybrid plants that contain the genetic determinants responsible for male sterility.
- Genetic determinants for male sterility may be located in the cytoplasm. Examples of cytoplasmic male sterility (CMS) were for instance described for Brassica species. However, genetic determinants for male sterility can also be located in the nuclear genome. Male-sterile plants can also be obtained by plant biotechnology methods such as genetic engineering.
- a particularly useful means of obtaining male-sterile plants is described in WO 89/10396 in which, for example, a ribonuclease such as a barnase is selectively expressed in the tapetum cells in the stamens. Fertility can then be restored by expression in the tapetum cells of a ribonuclease inhibitor such as barstar.
- Plants or plant varieties of the Musaceae family which may be treated according to the invention are herbicide-tolerant plants, i.e. plants made tolerant to one or more given herbicides. Such plants can be obtained either by genetic transformation, or by selection of plants containing a mutation imparting such herbicide tolerance.
- Herbicide-tolerant plants are for example glyphosate-tolerant plants, i.e. plants made tolerant to the herbicide glyphosate or salts thereof.
- glyphosate-tolerant plants can be obtained by transforming the plant with a gene encoding the enzyme 5-enolpymvylshikimate-3-phosphate synthase (EPSPS).
- EPSPS 5-enolpymvylshikimate-3-phosphate synthase
- EPSPS 5-enolpymvylshikimate-3-phosphate synthase
- EPSPS genes are the AroA gene (mutant CT7) of the bacterium Salmonella typhimurium, the CP4 gene of the bacterium Agrobacterium sp. , the genes encoding a Petunia EPSPS, a Tomato EPSPS, or an Eleusine EPSPS. It can also be a mutated EPSPS.
- Glyphosate-tolerant plants can also be obtained by expressing a gene that encodes a glyphosate oxido-reductase enzyme. Glyphosate-tolerant plants can also be obtained by expressing a gene that encodes a glyphosate acetyltransferase enzyme. Glyphosate-tolerant plants can also be obtained by selecting plants containing naturally occurring mutations of the abovementioned genes.
- herbicide-resistant plants are for example plants that are made tolerant to herbicides inhibiting the enzyme glutamine synthase, such as bialaphos, phosphinothricin or glufosinate.
- Such plants can be obtained by expressing an enzyme detoxifying the herbicide or a mutant of the glutamine synthase enzyme that is resistant to inhibition.
- One such efficient detoxifying enzyme is, for example, an enzyme encoding a phosphinothricin acetyltransferase (such as, for example, the bar or pat protein from Streptomyces species). Plants expressing an exogenous phosphinothricin acetyltransferase have been described.
- hydroxyphenylpyruvate dioxygenase HPPD
- Hydroxyphenylpyruvate dioxygenases are enzymes that catalyse the reaction in which para-hydroxyphenylpyruvate (HPP) is transformed into homogentisate.
- Plants tolerant to HPPD inhibitors can be transformed with a gene encoding a naturally occurring resistant HPPD enzyme, or a gene encoding a mutated HPPD enzyme.
- Tolerance to HPPD inhibitors can also be obtained by transforming plants with genes encoding certain enzymes enabling the formation of homogentisate despite the inhibition of the native HPPD enzyme by the HPPD inhibitor.
- the tolerance of plants to HPPD inhibitors can also be improved by transforming plants with a gene encoding an enzyme prephenate dehydrogenase in addition to a gene encoding an HPPD-tolerant enzyme.
- ALS inhibitors include, for example, sulphonylurea, imidazolinone, triazolopyrimidines, pyrimidinyloxy(thio)benzoates and/or sulphonylaminocarbonyltriazolinone herbicides.
- Different mutations in the ALS enzyme also known as acetohydroxyacid synthase (AHAS)
- AHAS acetohydroxyacid synthase
- sulphonylurea- and imidazolinone-tolerant plants are also described in for example WO 2007/024782.
- Other plants which are tolerant to imidazolinone and/or sulphonylurea can be obtained by induced mutagenesis, selection in cell cultures in the presence of the herbicide, or by mutation breeding.
- Plants or plant varieties of the Musaceae family which may also be treated according to the invention are insect-resistant transgenic plants, i.e. plants made resistant to attack by certain target insects.
- Such plants can be obtained by genetic transformation, or by selection of plants containing a mutation imparting such insect resistance.
- An "insect-resistant transgenic plant”, as used herein, includes any plant containing at least one transgene comprising a coding sequence encoding:
- an insecticidal crystal protein from Bacillus thuringiensis or an insecticidal portion thereof such as the insecticidal crystal proteins described online at: http://www.lifesci.sussex.ac.uk/Home/Neil_Crickmore/Bt/, or insecticidal portions thereof, e.g., proteins of the Cry protein classes CrylAb, CrylAc, CrylF, Cry2Ab, Cry3Ae or Cry3Bb, or insecticidal portions thereof; or
- a crystal protein from Bacillus thuringiensis or a portion thereof which is insecticidal in the presence of a second other crystal protein from Bacillus thuringiensis or a portion thereof, such as the binary toxin made up of the Cy34 and Cy35 crystal proteins; or

- an insect-resistant transgenic plant also includes any plant comprising a combination of genes encoding the proteins of any one of the above classes 1 to 8.
- an insect-resistant plant contains more than one transgene encoding a protein of any one of the above classes 1 to 8, in order to expand the range of target insect species affected or to delay insect resistance development to the plants by using different proteins insecticidal to the same target insect species but having a different mode of action, such as binding to different receptor binding sites in the insect.
- Plants or plant varieties of the Musaceae family obtained by plant biotechnology methods such as genetic engineering which may also be treated according to the invention are tolerant to abiotic stress factors.
- Such plants can be obtained by genetic transformation, or by selection of plants containing a mutation imparting such stress resistance.

- This example illustrates the efficacy of compositions containing Isotianil against Fusarium oxysporum Race 4 in bananas of the Cavendish type.
- the trial was laid out in Randomized Complete Block Design (RCBD) with four treatments (10 plants/treatment) with
- Trial 1 Initial trial result shows that Aliette at 2 grams + Isotianil 0.12ml/plant applied as preventive as soil drench at monthly interval gave 90% protection from fusarium infection. While Isotianil at 0.12ml and Aliette at 2 grams/plant applied as solo controls the infection at 30% and 50% respectively. In this conditions a synergy could be measured between the two compounds (Colby formula - Efficacy Abbott calculated: 65%). Moreover, symptom occurrence on treated plants was delayed by 22 days (Aliette and Isotianil solo) and 155 days ( Aliette + Isotianil) over the UTC.
- This example illustrates the efficacy of compositions containing Isotianil against Fusarium oxysporum Race 1 in banana Variety Gros Michel.
- the applications were carried out in Soil drenching starting in nursery 15 days before planting and continuing at plantation time followed by monthly intervals (applications at the base of the plant and in 40cm surroundings).
- Trial 2 Final trial result shows that Aliette at 2 grams + Isotianil 0.12ml/plant applied as preventive as soil drench at monthly interval gave 100% protection from fusarium infection 90 days after plantation. While Isotianil at 0.12ml and aliette at 2 grams/plant applied as solo controls the infection at 43% and 27% respectively. In these conditions a synergy could be measured between the two compounds (Colby formula - Efficacy Abbott calculated: 58%). Moreover, despite the lower persistency of single compounds the mixture shows a high level of control 180days after plantation and reduces the severity of infection in the highest stem levels.

- the rates of the 2 formulation were calculated to bring similar amount of Fosetyl AL and variable amount of Isotianil.
- All FEA+IST applications were carried out in drench application at monthly interval with 500ml water volume per plant. Initial trial results in 2 sites show that the use of FEA+IST in drench application method, whatever the ratio 10:1 or 60: 1, delays significantly the evolution of Fusarium oxysporum cubensis race 4. This delay of evolution of the disease is translated in the preservation of production potential in treated plots.
- This example illustrates the efficacy of two compositions containing fosetyl AL+ Isotianil applied in foliar spray against Fusarium oxysporum Race 4 on banana plantation.
