A continuous process for preparing microcapsules containing water-insoluble active principles, comprising:

Process for obtaining microcapsules

Use of formulations comprising polyurea microcapsules obtainable by interfacial polymerization of diphenylmethylen-4,4'-diisocyanate (MDI), optionally in admixture with polymethylenepolyphenylisocyanate (PAPI), said formulations having a prolonged knockdown and killing effect longer than at least 3 months, preferably at least of 6 months, still more preferably at least of 9 months from the application, wherein the microcapsules comprise:

Use of formulations having insecticidal activity

Concentrated microemulsions comprising: 1) 10-25 parts by weight of a pesticide with a solubility in water at 20&#xb0; C. lower than 1% l by weight and having a melting point from 10&#xb0; C. to 60&#xb0; C.; 2) 8-25 parts by weight of one or more solvents containing oxygen atoms, having a solubility in water at 20&#xb0; C. lower than 5% by weight and the Hildebrand solubility parameter in the range 16-21 MPa; 3) 10-20 parts by weight of a polyol; 4) 10-25 parts by weight of one or more non ionic surfactants having a HLB value from 9 to 15; 5) 2-10 parts by weight of one or more anionic surfactants; 6) water up to 100 parts by weight; wherein&#x2014;the ratio by weight between 2) and 1) ranges from 0.8:1 to 1.5:1;&#x2014;the ratio by weight between 4) +5) and 1) is in the range 0.5:1-3:1;&#x2014;the ratio by weight between 4) and 5) ranges from 1:1 to 4.1.

Pesticides formulations

Concentrated microemulsions comprising: 1) 10-25 parts by weight of a pesticide with a solubility in water 20&#xb0; C. lower than 1% by weight and having a melting point from 10&#xb0; C. to 60&#xb0; C.; 2) 8-25 parts by weight of one or more solvents containing oxygen atoms, having a solubility in water at 20&#xb0; C. lower than 5% by weight and the Hildebrand solubility parameter in the range 16-21 MPa: 3) 10-20 parts by weight of a polyol; 4) 10-25 parts by weight of one or more non ionic surfactants having a HLB value from 9 to 15; 5) 2-10 parts by weight of one or more anionic surfactants: 6) water up to 100 parts by weight; wherein&#x2014;the ratio by weight between 2) and 1) ranges from 0.8:1 to 1.5:1;&#x2014;the ratio by weight between 4)+5) and 1) is in the range 0.5:1-3:1;&#x2014;the ratio by weight between 4) and 5) ranges from 1:1 to 4.1.
