The continuing significance of chiral agrochemicals

Pest 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.

THE ROLE OF INTRAPOPULATION AND AGRO-METEOROLOGICAL FACTORS IN DYNAMICS OF POPULATION DENSITIES OF POTATO CYST NEMATODE GLOBODERA ROSTOCHIENSIS

Российский паразитологический журнал, 2016
Objective of research: to identify the role of intra-population and agro-meteorological factors in dynamics of populations of potato cyst-nematodes Globodera rostochiensis in potatoes grown as monoculture on loamy soil, and create the predictive ...

Rotenone Induces Morphological Damage and Reduction in Catecholamine Levels in the Central Nervous System of the Ascidian Styela plicata

Environmental Toxicology, EarlyView.
ABSTRACT Ascidians are invertebrates that occupy a key phylogenetic position as a sister group of the vertebrates. The organization of their central nervous system (CNS), with cortex and medulla, indicates a plesiomorphic character of the gray and white matter of vertebrates, making this group of animals useful for studies of neurodegenerative events ...

Prevalence of pest nematodes associated with soybean (Glycine max) in Wisconsin from 1998 to 2021

Journal of Nematology
The prevalence of Heterodera glycines and other cyst and vermiform genera was determined from 8,009 soil samples over two decades. Prevalence of cyst nematodes for farms increased from 16% in 1998 to 1999, reaching a peak of 40%, with marked differences ...

The role of Bacillus species in the management of plant-parasitic nematodes

Frontiers in Microbiology
Plant-parasitic nematodes (PPNs), including root-knot nematodes (Meloidogyne spp.), cyst nematodes (Heterodera and Globodera spp.), and other economically significant nematode species, pose severe threats to global agriculture.

Taxonomic Diversity of Fungi Associated with Some PCN Populations from Serbia [PDF]

Pesticidi i Fitomedicina, 2012
Increased content of pesticides in food chain resulted in using microorganisms asagents of biological control. The potato cyst nematodes (PCN) - Globodera pallida and G.rostochiensis belong to the group of the most important parasites - the quarantine ...

Iflaviruses in arthropods: when small is mighty

Insect Science, EarlyView.
Many arthropod species harbor iflaviruses, which often cause covert (asymptomatic) infections, but may still affect host fitness. We review the impact of iflaviruses on arthropod fitness, immunity, behaviour as well as the iflavirus’ host range, transmission, tissue tropism and the interactions with other microorganisms within arthropods.

The Role of Callose Deposition Along Plasmodesmata in Nematode Feeding Sites

Molecular Plant-Microbe Interactions, 2010
Infective second-stage juveniles of the obligate plant-parasitic root-knot and cyst nematodes invade plant roots to induce specialized feeding structures.

Neonicotinoid seed treatments do not consistently reduce insect feeding damage nor increase yields in Maryland soy

Agricultural and Forest Entomology, EarlyView.
We compared soybean plants from untreated and treated seeds across 4 sites and 3 years in Maryland. Neonicotinoid seed treatments (NST) provided little reduction in insect stippling damage and no reduction in chewing damage. NST did not result in increased plant biomass or bean yield. Abstract The use of neonicotinoid insecticides in seed treatments in

Infection Assay of Cyst Nematodes on Arabidopsis Roots

Bio-Protocol, 2015
Plant parasitic nematodes are devastating pests on many crops. Juveniles (J2) of cyst nematodes invade the roots to induce a syncytium. This feeding site is their only source of nutrients. Male nematodes leave the roots after the fourth molt to mate with
