Several different Advanced Oxidation Processes (AOPs) including ozonation at pH 6.5 and 10, photolysis and heterogeneous photocatalysis using TiO2 as semiconductor and dissolved oxygen as electron acceptor were applied to study the degradation of glyphosate (N-phosphonomethyl glycine) in water. The degree of glyphosate degradation, the reactions kinetic and the formation of the major metabolite, aminomethyl phosphonic acid (AMPA), were evaluated. Ozonation at pH 10 resulted in the maximum mineralization of glyphosate. It was observed that under the experimental conditions used in this study the degradation of glyphosate followed the first-order kinetics. The half-life obtained for glyphosate degradation in the O3/pH 10 process was 1.8 minutes. |

Here we report the characterization of a Spodoptera frugiperda multiple nucleopolyhedrovirus isolate, named SfMNPV-6nd, that does not cause the liquefaction of the host integument. The sequencing of the chitinase A (v-chiA) gene from SfMNPV-6nd revealed that it had a frameshift mutation that greatly reduced size of the putative enzyme. In order to evaluate the suitability of SfMPNV-6nd as a biopesticide, this isolate was compared with the highly virulent SfMNPV-19. Our results showed that the LC 50 of the isolates were not significantly different, but that SfMNPV-6nd took a longer period of time to kill second instarS. frugiperda than SfMNPV-19. |
