Relationship between seed harvesting method and seed physiological quality for a number of Pioneer maize hybrids [PDF]

open access: yes, 2012
The seed germination and seed vigor of eight Pioneer Hi-Bred maize hybrids were evaluated immediately after harvesting and a year later. The aim was to determine whether the seed showed loss of germination and vigor when shelled mechanically.

Reduced fitness cost accounts for the stability of a malathion‐resistant heterogeneous duplication haplotype in Ceratitis capitata field populations

open access: yesPest Management Science, EarlyView.
Malathion resistance in Spanish field populations of Ceratitis capitata is associated with a point mutation (R allele) and a heterogeneous duplication (RS haplotype) of the Ccace2 gene. The R allele imposes a higher fitness cost than the RS haplotype under laboratory and field conditions. An evolutionary model supports the stability of the RS haplotype

Pesticide use in integrated pest and pollinator management framework to protect pollinator health

open access: yesPest Management Science, Volume 81, Issue 4, Page 1691-1696, April 2025.
Integrated pest management (IPM) emphasizes non‐chemical methods, with pesticides as a last resort, while integrated pest and pollinator management (IPPM) integrates pollinator health into pest control strategies. Abstract Agricultural pesticides have historically been a critical tool in controlling pests and diseases, preventing widespread suffering ...

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.

Are we narrowing genetic variability in seed orchards? An attempt to answer, based on the analysis of microsatellite DNA of grafts growing in Scots pine (Pinus sylvestris L.) seed orchard in the Forest District Susz

open access: yesLeśne Prace Badawcze, 2015
Scots pine (Pinus sylvestris L.) is the most common species in Poland’s forest stands. The mode of pine stands renovation requires that silviculture practitioners have continuous access to seed banks.

The Role of Awareness in Sustainable Construction Materials Uptake in Developing Economies: Evidence From Nigeria

open access: yesSustainable Development, EarlyView.
ABSTRACT Sustainable Construction Materials (SCM) are crucial for reducing lifecycle emissions in the built environment, yet their adoption remains limited in many developing economies, such as Nigeria. This study investigates how awareness influences the adoption of SCM among professionals in Nigeria's Architecture, Engineering, and Construction (AEC)

Living Through a Changing Climate: Stress, Trauma, and Gendered Resilience Among Women in Coastal and Northern Ghana

open access: yesSustainable Development, EarlyView.
ABSTRACT Climate change is reshaping everyday life in Ghana through coastal erosion, flooding, erratic rainfall, water scarcity, extreme heat, and agricultural insecurity. This study examines how these changes produce stress, trauma, and gendered resilience among women in Salakope and Choggu Yapalsi, two climate‐vulnerable communities in coastal and ...
