Comparative Toxicity of Bordeaux Mixture by Ingestion and Cuticular Contact Under Climate Change Conditions on Trichogramma cordubensis

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
In the face of environmental contamination to copper, mainly resulting from frequent copper‐based fungicide applications, it is crucial to understand the side effects of these pesticides on non‐target organisms to improve pest management. Trichogramma cordubensis, used as a biological control agent against grape berry moths in vineyards, shows strongly

Efficacy and selectivity of post-emergent application of flumioxazin and oxyfluorfen in sunflower

open access: yesPlant, Soil and Environment, 2011
Four efficacy and selectivity small plot field trials were carried out in four sunflower hybrids at two localities in Middle Bohemia during 2008 and 2009 with herbicides containing the active ingredients flumioxazin and fluorochloridone.

Effects of Triclopyr on Variable-Leaf Watermilfoil [PDF]

open access: yes, 2003
The objective of the study described here was to determine the effect on variable-leaf watermilfoil of various combinations of triclopyr concentrations and exposure times using dosage rates that controlled Eurasian watermilfoil under laboratory and ...

Movement and Survival of Spodoptera litura (Lepidoptera: Noctuidae) Neonate Larvae on Cotton Expressing Bacillus thuringiensis Proteins

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
Spodoptera litura neonates showed increased movement on Bt‐expressing Bollgard 3 (BG) cotton leaf discs but did not initially avoid it. Survival was higher when larvae could move from BG3 to non‐Bt leaf discs. On whole plants, more larvae dispersed from hatching on BG3 cotton compared to non‐Bt cotton. These findings suggest the larval movement differs

An Evaluation of Herbicides for Broadleaf-Weed Control in Rapeseed: Efficacy, Phytotoxicity, and Soil Persistence Studies [PDF]

open access: yes, 1984
At the recommended rates (1.0 lb/A for trifluralin, ethalfluralin, EL5261; 0.75 lb/A for dinitramine; 1.2 lb/A for nitrofen), none of the herbicides we evaluated in these studies reduced rapeseed stands, yields, or test weights. However, at higher rates (

Economic and Biological Evaluation of Pheromone Trap Types for Western Bean Cutworm, Striacosta albicosta, Monitoring in Dry Edible Bean Fields

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
Pheromone trap use for monitoring Striacosta albicosta in dry edible beans was evaluated across multiple trap designs, lure replacement intervals, and insecticide timings. Bucket traps captured the most moths, yet trap counts poorly predicted crop damage.

Coupling of both a transactivation module and a double‐stranded DNA‐binding domain boosts Cas12i3 variant‐based cytosine and adenine editing in plants

open access: yesJournal of Integrative Plant Biology, EarlyView.
Fusions of a transactivation module and a double‐stranded DNA‐binding domain produced effective Cas12i3 variant‐based cytosine and adenine base editors, with improved C‐to‐T and A‐to‐G base editing efficiency and expanded editing window. Generated herbicide‐resistant rice germplasm by using these base editors demonstrates their potential for precise ...
