  • Paraquat exposure delays late-stage Leydig cell differentiation in rats during puberty. [Journal Article]
    Environ Pollut 2019; 255(Pt 2):113316Li H, Hong T, … Ge RS
  • Paraquat is a fast and non-selective herbicide that is widely used in crop cultivation and conservation tillage systems. Animal experiments have shown that paraquat decreases sperm quality and testicular organ coefficient, but its effects on the development of Leydig cells remain unclear. The objective of the current study was to investigate the effects of paraquat exposure on the Leydig cell dev…
  • Pesticide-Induced Planthopper Population Resurgence in Rice Cropping Systems. [Journal Article]
    Annu Rev Entomol 2019Wu J, Ge L, … Stanley D
  • Planthoppers are serious rice pests in Asia. Their population resurgence was first reported in the early 1960s, caused mainly by insecticides that indiscriminately killed beneficial arthropods and target pests. The subsequent resurgence involved two mechanisms, the loss of beneficial insects and insecticide-enhanced planthopper reproduction. In this review, we identify two forms of resurgence, ac…
  • Glyphosate but not Roundup® harms earthworms (Eisenia fetida). [Journal Article]
    Chemosphere 2019; 241:125017Pochron S, Simon L, … Yudell M
  • Glyphosate is the active ingredient in Roundup® formulations. While multiple studies have documented the toxicity, environmental persistence, and tendency to spread for glyphosate and Roundup®, few studies have compared the toxicity of glyphosate-based formulations to the toxicity of pure glyphosate for soil invertebrates, which contact both the herbicide and the formulations. Hundreds of formula…
  • A Fluorogenic Assay for Acetohydroxyacid Synthase: Design and Applications. [Journal Article]
    Anal Chem 2019Xie Y, Zhang C, … Xi Z
  • Acetohydroxyacid synthase (AHAS) exists in plants and many microorganisms (including gut flora) but not in mammals, making it as an attractive drug target. Fluorescent-based methods should be practical for high-throughput screening of inhibitors. Herein, we describe the development of the first AHAS fluorogenic assay based on an ICT-based fluorescent probe. The assay is facile, sensitive, continu…
  • Application of a plant biostimulant to improve maize (Zea mays) tolerance to metolachlor. [Journal Article]
    J Agric Food Chem 2019Panfili I, Bartucca ML, … Del Buono D
  • Plant biostimulants (PBS) increase crop productivity inducing beneficial processes in plants. Although PBS can stimulate plant tolerance to some abiotic stresses, their effect in improving crop resistance to herbicide injuries has been barely investigated. Therefore, a study on the effect of a biostimulant (Megafol® - Megafol) on maize (Zea mays L.) tolerance to a chloro-acetanilide herbicide (me…
