Furthermore, the present © invention relates to a method of controlling Panama disease in plants of the Musaceae (1) family by treating them with Isotianil (I). o o Use of Isotianil against Panama disease The present invention relates to the use of Isotianil (1ST) (formula (I)) for controlling Panama disease in plants of the Musaceae family. Furthermore, the present invention relates to a method of controlling Panama disease in plants of the Musaceae family by treating them with Isotianil or formulations containing Isotianil (formula (I)). Furthermore, the present invention relates to mixtures of Isotianil with at least one further active ingredient selected from fungicides, bactericides, acaricides, nematicides, herbicides, insecticides, safeners, host defence inducers, soil-improvement products or products for reducing plant stress, for example Myconate, in order to widen the spectrum of action or to prevent the development of resistance, for example, for the treatment of Panama disease. In a preferred embodiment, the present invention relates to mixtures of Isotianil with at least one further active ingredient selected from Fosetyl-Al, and mono- and dibasic sodium, potassium and ammonium phosphites (e.g., Phostrol) for controlling Panama disease in plants of the Musaceae family. The compound of formula (I) is known from WO 99/024 413, WO 2006/098128, JP 2007-84566 and WO 96/29871, inter alia. Invention 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. So far the Fusarium pathogen is resistant to fungicides and there is no chemical solution available. In WO 2010/037482, 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. A first subject matter of the invention is therefore the use Isotianil for controlling Panama disease in plants of the Musaceae family. A further subject matter of the invention is therefore the use of Isotianil for controlling Panama disease in plants of the genus Musa. A further subject matter of the invention is a method of controlling Panama disease in plants of the Musaceae family, characterized in that the plants of the Musaceae family are treated with Isotianil. Another subject matter of the instant invention is the use and the methods cited above, wherein Isotianil is used in combination with at least one further active ingredient selected from fungicides, bactericides, acaricides, nematicides, herbicides, insecticides, safeners, host defence inducers, soil- improvement products or products for reducing plant stress, for example Myconate, in order to widen the spectrum of action or to prevent the development of resistance, for example. A preferred embodiment of the instant invention is the use and the methods cited above, wherein Fusarium oxysporumf.sp.cubense race 1 or race 4 causes the Panama disease. Another preferred embodiment of the instant invention is the use and the methods cited above, wherein Isotianil or Isotanil in a combination with at least one further active ingredient is applied, wherein the further a.i. is preferably selected from Fosetyl-Al, and mono- and dibasic sodium, potassium and ammonium phosphites, and more preferred Fosetyl-Al. Another further preferred embodiment of the instant invention is the use and the methods cited above, wherein the method of use is by drip application, preferably every 30 days, more preferably every 14 days, with 2.5 to 0.5 g Fosetyl-Al/plant and 0.035 to 0.015 g IST/plant, more preferred with 2.0 to 1.0 g Fosetyl-Al/plant and 0.03 to 0.02 g IST/plant, even more preferred with 2.0 to 1.0 g Fosetyl- Al/plant and 0.03 to 0.02 g IST/plant and most preferred with 1.6 g Fosetyl-Al/plant and 0.024 g IST/plant. Another further preferred embodiment of the instant invention is the use and the methods cited above, wherein Isotianil is used in combination with Fosetyl-Al in a ratio in wt% of 1 to 60 to 1 to 75. Another further preferred embodiment of the instant invention is the use and the methods cited above, wherein the method of use is by drip application, preferably every 30 days, more preferably every 14 days, with 0.45 to 0.1 g Fosetyl-Al/plant and 0.04 to 0.015 g IST/plant, more preferred with 0.4 to 0.15 g Fosetyl-Al/plant and 0.04 to 0.02 g IST/plant, even more preferred with 0.35 to 0.25 g Fosetyl-Al/plant and 0.035 to 0.025 g IST/plant and most preferred with 0.28 g Fosetyl-Al/plant and 0.028 g IST/plant. Another further preferred embodiment of the instant invention is the use and the methods cited above, wherein Isotianil is used in combination with Fosetyl-Al in a ratio in wt% of 1 to 5 to 1 to 15. Another further preferred embodiment of the instant invention is the use and the methods cited above, wherein the method of use is by drip application, preferably every 30 days, more preferably every 14 days, with 0.035 to 0.015 g IST/plant, more preferred with 0.03 to 0.02 g IST/plant, even more preferred with 0.03 to 0.02 g IST/plant and most preferred with 0.024 g IST/plant.

These materials, which have traditionally been considered waste, can be used to produce fully bio-based composites to replace petroleum-derived synthetic plastics in some sectors such as packaging, the automotive industry, and implants. The fibres extracted from Musaceae have mechanical, thermal, and physicochemical properties that allow them to compete with other natural fibres such as sisal, henequen, fique, and jute, among others, which are currently used in the preparation of bio-based composites. Despite the potential use of Musaceae residues, there are currently not many records related to bio-based composites’ developments using starches, flours, and lignocellulosic fibres from banana and plantain pseudostems. In this sense, the present study focusses on the description of the Musaceae components and the Citation: Castañeda Niño, J.P.; Mina review of experimental reports where both lignocellulosic fibre from banana pseudostem and flour Hernandez, J.H.; Valadez González, and starch are used with different biodegradable and non-biodegradable matrices, specifying the A.

Data was collected from three villages of Geku circle, Upper Siang District between the year 2016-2019, covering more than 50% of the total households using semi-structured questionnaires, personal interviews, focused group discussions and transect walk with the core respondents. A total of 301 taxa falling in 203 genera and 85 families are recorded from the Komkar-Adi Biocultural Landscape (KABL), invariably used as food, medicine and cultural materials which is directly and indirectly linked with livelihood security, community survival, protection and preservation of the traditional culture and nature.
