Bionanotecnologia snedds employed in the distribution of polar extracts of Tephrosia toxicaria pers. With applying pesticide / nematicide

摘要

In the present invention were obtained biodegradable products of the type snedds (autonanoemulsão), prepared on the basis of the extracts (aqueous and hydroalcoholic plant Tephrosia toxicaria (stem),The leaves and roots), with preferential application pesticide / nematicide. The systems snedds - Nano - TT (bionanoestruturados snedds the basis of T.Toxicaria) containing polar extracts taken at low concentrations (0.025% - 0.8%), were evaluated in the fight against nematoides Meloidogyne enterolobii and Meloidogyne javanica.The bioproducts snedds - Nano - TT are effective in the prevention of quantitatively hatching of eggs and mortality of juveniles / J2, with optimal concentration around 0.1% (relative to the dilution of snedds system containing 10 mg of extract and in 1 ml solution).For the large scale production of snedds - Nano - TT, the components are: non ionic surfactant preferred class of Tweens (10% to 16%), vegetable oil percentage low (0.5% to 2.0%) and doubly distilled water in a high percentage (89.5% and 82.0%); followed by the step of encapsulation of extracts of t. toxicaria.The whole plant pesticide / nematicide presents action and can be marketed with the use of biotechnology snedds,With reference to extend it to other activities, pesticides or control of pests, such as mosquitoes that transmit dengue, chikungunya, Zika virus, malaria, filariasis, yellow fever.
