It refers to agricultural ingredients, including at least 99.9% to 0.1% of dioxin or diarrhea urea, such as N, n '- dioxin, and at least 0.1% to 99.9% by weight, such as cobalt, nickel, silver or other metal compounds. This component is suitable for plants when they are physiologically sensitive, resulting in a comprehensive and long-term reduction of ethylene, allowing for the regulation of phenotypic parameters and the improvement of crop production parametersSe refiere a una composicion agricola que comprende de 99,9 a 0,1 % de al menos un diacilo o diaril urea tal como una N,N'-diformilurea y de 0,1 % a 99,9 % en peso de al menos un complejo de metales tales como complejos de metales de cobalto, niquel, plata u otros. Dicha composicion se aplica a plantas en momentos fisiologicamente sensibles dando como resultado la reduccion completa y prolongada de etileno permitiendo la regulacion de parametros fenotipicos mejorando los parametros de produccion de cultivos
