Description

/ RHÔNE-POULENC AGRICULTURE LTD. &quot;.MÉTODO PARA INIBIR A GERMINAÇÃO DE BATATAS UTILIZANDO A CARBETAMIDA&quot; A presente invenção diz respeito ao controlo e inibição da germinação de plantas tuberosas e mais especialmente à inibição química dessa germinação mediante a aplicação de carbe-tamida. A carbetamida é um composto de fórmula c6h5-nh-coo-ch(ch3)-co-nh-c2h5 conhecido também por D-N-etil-lactamida-fenilcarbamato ou N-fenil-1-(etilcarbamoí1)-etilcarbamato (isómero D)./ RHÔNE-POULENC AGRICULTURE LTD. &quot; METHOD FOR INHIBITING POTATO GERMINATION USING CARBETAMIDE &quot; The present invention relates to the control and inhibition of the germination of tuberous plants and more especially to the chemical inhibition of such germination by the application of carbe-tamida. Carbetamide is a compound of the formula known as D-N-ethyl-lactamide-phenylcarbamate or N-phenyl-1- (ethylcarbamoyl) ethylcarbamate (D-isomer).

As batatas (solanum tuberosum) podem armazenar-se durante períodos prolongados desde a colheita até ao consumo. Durante estes períodos o tubérculo tem tendência para germinar o que provoca uma certa deterioração que se deve evitar. Conhecem-se diversos agentes químicos capazes de inibir a germinação em tais circunstâncias (por exemplo, clorprofam, profam, tecnaze-ne) que no entanto apresentam algumas desvantagens. Recentemente verificou-se que a carbetamida é um inibidor eficaz da germinação, que apresenta algumas vantagens relativamente a materiais -2- / iPotatoes (solanum tuberosum) can be stored for prolonged periods from harvest to consumption. During these periods the tuber tends to germinate which causes a certain deterioration to be avoided. Various chemical agents capable of inhibiting germination are known in such circumstances (for example, chlorpropham, profam, tecnaze-ne) which however have some drawbacks. Carbetamide has recently been found to be an effective inhibitor of germination, which has some advantages over

correntemente utilizados.currently used.

Consequentemente a presenta invenção fornece um método que permite a inibição da germinação das batatas durante a armazenagem que consiste na aplicação sobre os tubérculos, antes ou durante a armazenagem, de uma quantidade de carbetamida suficiente para inibir a sua germinação. A carbetamida é um herbicida selectivo conhecido que tem sido largamente utilizado na cultura de forragem e na semea-ção de brassicáceas e legumes e numa grande variedade de outras culturas. Utiliza-se também para controlar as ervas daninhas em terras de pousio, pomares, vinhas e viveiros. A carbetamida também exibe acção reguladora do crescimento das plantas e pode utilizar-se como un inibidor eficaz do aparecimento de novos ramos nas plantas do tabaco porque bloqueia ou inibe o crescimento de gomos axilares mediante modificação da actividade meristemática. Contudo, o modo de acção de acordo com a presenta invenção é diferente porque inibe toda a germinação numa sementeira já colhida, enquanto no tabaco a acção principal consiste na inibição selectiva do crescimento de gomos especiais, isto é, não terminais, na planta ainda em desenvolvimento . 0 método de acordo com a presenta invenção para o tratamento de batatas pode utilizar uma qualquer das composições conhecidas de carbetamida. Estas composições conhecidas podem apresentar-se sob a forma de pós molháveis, pés soltos para polvilhação, soluções, concentrados emulsionáveis, emulsões, -3- f .% concentrados para suspensões e aerossóis e incluem, na generalidade, 1 a 95%, em peso, de material activo e o peso restante sob a forma de veículos, agentes tensioactivos e outros adjuvantes aceitáveis tais como agentes de adsorção, agentes de aglutinação, agentes de penetração, agentes estabilizantes e outros materiais activos. 0 termo &quot;veículo&quot; designa um material orgânico ou inorgânico, natural ou sintético com o gual a carbetamida se associa de modo a facilitar a aplicação, o transporte ou o manuseamento. 0 veículo pode ser sólido (por exemplo, uma argila ou um silicato natural ou sintético) ou líquido (por exemplo, água ou dissolventes orgânicos incluindo cetonas tais como a acetona e a acetofenona e cetonas cíclicas tais como a ciclo-hexanona; a dimetilformamida; alcanóis inferiores como, por exemplo, o metanol ou o etanol desnaturado; hidrocarbone-tos clorados tais como o cloreto de metileno; dissolventes aromáticos tais como o tolueno e o xileno; e fracções do petróleo). 0 agente tensioactivo pode ser um agente emuldionante, um agente dispersante ou um agente molhante e pode ser iónico ou não iónico. Agentes emulsionantes apropriados incluem materiais ca-tiónicos, aniónicos, não iónicos ou anfotéricos geralmente utilizados como, por exemplo, sais de ácidos poliacrílicos, de ácidos ligno-sulfónicos e condensados de óxido de etileno com alcoóis gordos, ácidos gordos e aminas gordas.Accordingly the present invention provides a method which enables the inhibition of potato germination during storage which consists in applying to the tubers, before or during storage, a quantity of carbetamide sufficient to inhibit its germination. Carbetamide is a known selective herbicide that has been widely used in fodder crops and in the cultivation of brassicaceae and legumes and in a wide variety of other crops. It is also used to control weeds in fallow land, orchards, vineyards and nurseries. Carbetamide also exhibits plant growth regulating action and can be used as an effective inhibitor of the appearance of new branches in tobacco plants because it blocks or inhibits the growth of axillary buds by modifying meristematic activity. However, the mode of action according to the present invention is different because it inhibits all germination in a plant already harvested, whereas in tobacco the main action consists in the selective inhibition of the growth of special, ie non-terminal, buds in the plant still in development . The method according to the present invention for the treatment of potatoes may use any of the known compositions of carbetamide. These known compositions may be in the form of wettable powders, loose powder feet, solutions, emulsifiable concentrates, emulsions, concentrates for suspensions and aerosols, and generally comprise 1 to 95% by weight , of active material and the balance weight in the form of carriers, surfactants and other acceptable adjuvants such as adsorptive agents, binding agents, penetrating agents, stabilizing agents and other active materials. The term &quot; vehicle &quot; means an organic or inorganic material, natural or synthetic, as the carbobenzamide is associated in order to facilitate application, transport or handling. The carrier may be solid (e.g., a clay or a natural or synthetic silicate) or liquid (e.g., water or organic solvents including ketones such as acetone and acetophenone and cyclic ketones such as cyclohexanone; dimethylformamide; lower alkanols such as methanol or denatured ethanol, chlorinated hydrocarbons such as methylene chloride, aromatic solvents such as toluene and xylene, and petroleum fractions). The surfactant may be a blowing agent, a dispersing agent or a wetting agent and may be ionic or nonionic. Suitable emulsifying agents include commonly used cationic, anionic, nonionic or amphoteric materials such as, for example, salts of polyacrylic acids, lignosulfonic acids and condensates of ethylene oxide with fatty alcohols, fatty acids and fatty amines.

Outros adjuvantes que se podem incluir nestas composições com vista a uma aplicação simultânea são fungicidas e insecti-cidas. Exemplos de fungicidas que se podem aplicar com a carbetamida são imazalil e iprodione. E preferível aplicar a carbetamida como uma disper- são num meio líquido ou sólido caracteristicamente em concentrações de 0,5 a 50% em peso. A carbetamida é solúvel na água numa proporção de apro-ximadamente 3,5g/litro. Consequentemente, prefere-se aplicar a carbetamida, quando em meio líquido, sob a forma de uma dispersão emulsionada na água via a emulsificação de uma solução concentrada num dissolvente apropriado. Os dissolventes, o agente activo e os agentes tensioactivos preparam-se sob a forma de concentrados emulsionáveis que se diluem depois com água, antes da aplicação, até à concentração apropriada. Para a preparação de dispersões que se destinam a aplicar por pulverização preferem-se composições concentradas líquidas. Contudo, podem modificar-se estes concentrados para aplicação por dispersão via aerossóis ou nebulizadores. As técnicas de modificação utilizadas são técnicas convencionais.Other adjuvants which may be included in such compositions for simultaneous application are fungicidal and insecticidal. Examples of fungicides that can be applied with the carbobetamide are imazalil and iprodione. It is preferable to apply the carbetamide as a dispersion in a liquid or solid medium typically in concentrations of 0.5 to 50% by weight. Carbetamide is water soluble at a ratio of about 3.5 g / liter. Accordingly, it is preferred to apply the carbetamide, when in liquid medium, as a dispersion emulsified in water via the emulsification of a concentrated solution in an appropriate solvent. The solvents, the active agent and the surfactants are prepared as emulsifiable concentrates which are then diluted with water, prior to application, to the appropriate concentration. Liquid concentrate compositions are preferred for the preparation of dispersions which are to be sprayed. However, these concentrates can be modified for dispersion application via aerosols or nebulizers. Modification techniques used are conventional techniques.

As fórmulas líquidas de carbetamida podem aplicar-se por métodos manuais tais como pulverização manual, regadores, tubos de imersão, etc., embora se possam utilizar dispositivos convencionais (por exemplo, mesas rolantes) em operações de larga escala. As fórmulas líquidas também se podem distribuir utilizando pulverizadores. A carbetamida também se pode aplicar sob a forma de um sólido, isto é, sob a forma de pós molháveis, pós finos ou grânulos. Estas composições aplicam-se por nebulização ou dispersão dos sólidos, nas quantidades pretendidas, sobre os produtos armazenados que se pretende tratar, por exemplo utilizando disper-sadores de grânulos. Para aplicar agentes sólidos preferem-se pós molháveis ou grânulos.Liquid carbetamide formulas may be applied by manual methods such as hand spraying, watering cans, immersion tubes, etc., although conventional devices (eg, rolling tables) may be used in large-scale operations. Liquid formulas may also be dispensed using sprayers. Carbetamide may also be applied in the form of a solid, i.e. in the form of wettable powders, fine powders or granules. These compositions are applied by misting or dispersing the solids, in the desired amounts, onto the stored products to be treated, for example using granule dispersers. Solids or granules are preferred for applying solids.

As composições concentradas, líquidas, sólidas ou semi-sólidas diluem-se antes de se aplicarem para assegurar uma distribuição uniforme. 0 grau de diluição necessário depende do modo de aplicação. Quando se nebuliza a carbetamida sob a forma de um líquido via uma dispersão aquosa, o nível de concentração do ingrediente activo pode variar entre 4,5 e 50% em peso.The concentrated, liquid, solid or semi-solid compositions are diluted prior to application to ensure uniform distribution. The degree of dilution required depends on the mode of application. When carbetamide is nebulized as a liquid via an aqueous dispersion, the concentration level of the active ingredient may range from 4.5 to 50% by weight.

As composições sólidas utilizam-se de modo a fornecerem, aproximadamente, a mesma concentração de ingrediente activo fornecido pelas composições liquidas..The solid compositions are used so as to provide approximately the same concentration of active ingredient provided by the liquid compositions.

Como se afirmou antes, a carbetamida é compatível com outras substâncias activas, tais como fungicidas e insecticidas e podem, consequentemente, aplicar-se sobre as colheitas armazenadas em associação com as mesmas. Uma tal aplicação pode ser sequencial ou simultânea. A título exemplificativo, as composições seguintes podem utilizar-se no método de acordo com a presente invenção. Pós molháveis (percentagem em peso)As stated above, carbetamide is compatible with other active substances, such as fungicides and insecticides and can therefore be applied to the harvests stored in association therewith. Such an application may be sequential or simultaneous. By way of example, the following compositions may be used in the method according to the present invention. Wettable powders (percentage by weight)

Ciclo-hexanona (veículo) q.b.p. 1000 cc A carbetamida possui uma DL^g aguda em ratos de 11000 mg/kg do peso do corpo do animal e é praticamente isenta de toxicidade crónica. As aplicações tópicas no olho do coelho (5 mg) e na pele do mesmo animal (creme a 5¾) indicam também ausência de efeitos irritantes.Cyclohexanone (vehicle) q.s. 1000 cc Carbetamide has an acute LD50 in rats of 11000 mg / kg body weight of the animal and is practically free of chronic toxicity. Topical applications in rabbit eye (5 mg) and skin of the same animal (5 creme cream) also indicate no irritant effects.

Assim, a carbetamida é menos tóxica ou irritante para os mamíferos do que os inibidores da germinação anteriormen-te utilizados e é mais segura para os trabalhadores sem conhecimentos profissionais que a utilizam. Além do mais, na ausência de ✓ toxicidade significativa, os restos detectados nos tubérculos representam um risco significativamente menor para o meio ambiente e para a saúde dos manipuladores e dos consumidores. A carbetamida também produz menos manchas nos tubérculos tratados, o que os torna mais aceitáveis para consumo. A carbetamida é também muito menos volátil do que os inibidores de germinação que actualmente se utilizam. Esta caracterfstica permite pois selectividade de tratamento e impede a contaminação cruzada uma vez que a área de efeito de um tratamento não se expandirá. Consequentemente, não é necessário separar tubérculos tratados de outros não tratados ou de outras colheitasThus, carbetamide is less toxic or irritant to mammals than the germination inhibitors previously used and is safer for workers without professional knowledge who use it. Furthermore, in the absence of significant toxicity, the debris detected in the tubers represents a significantly lower risk to the environment and to the health of handlers and consumers. Carbetamide also produces fewer stains on the treated tubers, which makes them more acceptable for consumption. Carbetamide is also much less volatile than the presently used germination inhibitors. This feature thus allows for selectivity of treatment and prevents cross-contamination since the area of effect of a treatment will not expand. Consequently, it is not necessary to separate treated tubers from other untreated or other crops

Com o tratamento de acordo com a presente invenção também não se verificam perdas de p-e-sõ superiores ãs dos tratamentos convencionais. 0 exemplo seguinte ilustra a utilização da car-betamida de acordo com a presente invenção.With the treatment according to the present invention there is also no loss of p-e-s higher than conventional treatments. The following example illustrates the use of the carbamamide according to the present invention.
