“…Under typical environmental conditions, tembotrione can be found in its ionic form which is non-volatile, highly soluble, and stable in water. 40 The structure of the tembotrione molecule and other benzoylcyclohexanediones can be divided into a benzoyl and dione (cyclohexanedione) moiety, which have independent roles in the activity of the herbicide. 10,17,41 The -diketone moiety, which all triketones share, mimics the -keto acid chain of HPP.…”

Further research with the aim of identifying the gene or genes responsible for conferring metabolic resistance to HPPD inhibitors should focus on cytochrome P450s. Such research is important because non-target-site-based resistance (NTSR) poses the threat of cross resistance to other chemical classes of HPPD inhibitors, other herbicide modes of action, or even unknown herbicides. © 2017 Society of Chemical Industry.

“…The β-triketones responsible for contact toxicity against SWD possess multiple carbonyl groups on a six-membered ring (cyclohexane), and this structure is rare in natural phytotoxins. Many derivatives of leptospermone, such as nitisinone and sulcotrione, have been synthesized and selected as herbicides [ 41 ]. Some new derivatives of β-triketones with new modes of action, as envisaged by this experiment, are also expected to be used as novel insecticides.…”

Myrtaceae Plant Essential Oils and their β-Triketone Components as Insecticides against Drosophila suzukii

Spotted wing drosophila (SWD, Drosophila suzukii (Matsumura), Diptera: Drosophilidae) is recognized as an economically important pest in North America and Europe as well as in Asia. Assessments were made for fumigant and contact toxicities of six Myrtaceae plant essential oils (EOs) and their components to find new alternative types of insecticides active against SWD. Among the EOs tested, Leptospermum citratum EO, consisting mainly of geranial and neral, exhibited effective fumigant activity. Median lethal dose (LD50; mg/L) values of L. citratum were 2.39 and 3.24 for males and females, respectively. All tested EOs except Kunzea ambigua EO exhibited effective contact toxicity. LD50 (µg/fly) values for contact toxicity of manuka and kanuka were 0.60 and 0.71, respectively, for males and 1.10 and 1.23, respectively, for females. The LD50 values of the other 3 EOs-L. citratum, allspice and clove bud were 2.11–3.31 and 3.53–5.22 for males and females, respectively. The non-polar fraction of manuka and kanuka did not show significant contact toxicity, whereas the polar and triketone fractions, composed of flavesone, isoleptospermone and leptospermone, exhibited efficient activity with the LD50 values of 0.13–0.37 and 0.22–0.57 µg/fly for males and females, respectively. Our results indicate that Myrtaceae plant EOs and their triketone components can be used as alternatives to conventional insecticides.

“…A worldwide social concern over the indirect or deliberate introduction of organic pollutants into the environment is unquestionably. For this reason, the scientific community invests a great effort in the development of new and economically viable technologies to reduce, mitigate and eliminate the xenobiotics and pollutants from the environment . Bacterium@LDH biohybrids have been successfully applied in bioremediation as a mechanism of xenobiotics dissipation, such as pesticides or dyes .…”

This review highlights the current research on the interactions between biological cells and Layered Double Hydroxides (LDH). The as-prepared biohybrid materials appear extremely attractive in diverse fields of application relating to health care, environment and energy production. We describe how thanks to the main features of biological cells and LDH layers, various strategies of assemblies can be carried out for constructing smart biofunctional materials. The interactions between the two components are described with a peculiar attention to the adsorption, biocompatibilization, LDH layer internalization, antifouling and antimicrobial properties. The most significant achievements including authors' results, involving biological cells and LDH assemblies in waste water treatment, bioremediation and bioenergy generation are specifically addressed.
