Abstract

Una suspension acuosa de microcápsulas, que contienen un material biologicamente activo, comprendiendo dicha suspension además un material adhesivo en unacantidad efectiva para permitir que las citadas microcápsulas se adhieran a un sustratodeseado. Preferentemente el material adhesivo se encuentra en la formade una suspension acuosa de microesferas de adhesivo o en la forma de látex adhesivo no esférico. Como alternativa, el material adhesivo de la suspensioncomprende entre un 60 y un100% en peso aproximadamente de las microesferas de adhesivo sensibles a la presion, elastoméricas, huecas, poliméricas, acrilato,inherentemente viscosas, infusibles, insolubles en solvente y dispersables en solvente, con un diámetro de por lomenos, 1 micro metro y, entre 0 y un 40% enpeso aproximadamente de un adhesivo poliacrilato no esférico. Un procedimiento para llevar a cabo la preparacion de una suspension acuosa de microcápsulasadherentes, que está caracterizado porque comprendela mezcla de una suspension acuosa A) de microcápsulas con un pH mayor que 7 aproximadamente, con unasuspension acuosa, B) de adhesivo con un pH mayor que 7 aproximadamente, que se selecciona entre el grupo formado por microesferas adherentes,adhesivo delátex acuos o no esférico o una combinacion de microesferas adherentes y adhesivo de látex acuoso no esférico. Un procedimiento para llevar a cabo lapreparacion de una suspension acuosa de microcápsulas adherentes, que está caracterizadoporque comprende la mezc la de la suspension acuosa A) pero con un pHmenor que 7 aproximadamente, con una suspension acuosa B) pero con un pH menor que 7 aproximadamente. Un método para la aplicacion de microcápsulas sobre unsustrato deseado,caracterizado porque comprende a ) preparar una suspension acuosa de microcápsulas, la citada suspension comprende, además, un materialadhesivo en una cantidad efectiva para permitir que dichas microcápsulas se adhieran a un sustrato deseado, b)administrar dicha suspension en un su stratodeseado a través de un dispositivo pulverizador en la forma de un aerosol. La suspension puede aplicarse en sustratos orgánicos como, por ejemplo, follaje,
