The continuing significance of chiral agrochemicals

open access: yesPest Management Science, Volume 81, Issue 4, Page 1697-1716, April 2025.
In the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.

High Glucosinolate Mustard and Potato Trial [PDF]

open access: yes, 2013
High glucosinolate mustard (HGM) can be planted as a cover crop to suppress weeds and disease. Studies have shown a reduction in soil-borne diseases, as well as advantages in mitigating weed pressure, after planting HGM cover crops.

De Novo Design and Synthesis of Novel Benzoxazinone Derivatives Targeting Dihydroxyacid Dehydratase

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Dihydroxyacid dehydratase (DHAD), a key enzyme in the branched‐chain amino acid (BCAA) synthesis pathway, is a promising herbicide target. Currently, no commercial herbicides target DHAD, and no inhibitors are in development. Structural analysis suggests that coordination with iron–sulfur clusters and hydrophobic interactions with Tyr215 and ...

Fungi isolated from soil with quicksets of Chamaecyparis lawsoniana and their influence on the growth of Phytophthora cinnamomi and Rhizoctonia solani

open access: yesPlant Protection Science, 2002
Chamaecyparis lawsoniana is often attacked by other pathogens (from genera: Phytophthora, Pythium, Fusarium, Rhizoctonia) both when the quicksets are taken root and later, when the young plants are planted. The aim of the study was to determine an effect

High‐Efficiency and Eco‐Friendly Management of Multiple Fungal Diseases by a Novel Carbon Dots sCDP Delivered RNA Nano‐Pesticides

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT RNA‐based pesticides represent a transformative approach in agricultural disease management, offering an environmentally sustainable alternative to conventional chemical fungicides. However, key challenges such as rapid RNA degradation in the environment and inefficient uptake hinder widespread adoption.

Evolutionary and genomic comparisons of hybrid uninucleate and nonhybrid Rhizoctonia fungi

open access: yesCommunications Biology, 2021
Li et al. generate chromosome-scale genome assemblies of the three nuclear types of the basidiomycetous fungi Rhizoctonia isolates. Genomic comparisons implicate that uninucleate genomes were hybrids derived potentially from binucleate ancestors ...
