Analysis of fumigant residues - A critical review

open access: yes, 1999
This review concentrates on the main fumigants currently applied to commodities: phosphine (PH3) and methyl bromide (CH3Br). It discusses possible new fumigants, such as carbonyl sulfide (COS) and ethyl formate (EtF), that may be able to be applied in ...

Hydrologic, Plant and Soil Controls on Microbial Biomass and Enzyme Activities in a Natural and a Restored Freshwater Marsh of Eastern Ontario, Canada

open access: yesFreshwater Biology, Volume 71, Issue 10, October 2026.
ABSTRACT The hydrology and drainage history of freshwater marshes influence their soil properties and plant communities, which in turn affect microbial biomass and extracellular enzyme activities that regulate the biogeochemistry and functioning of the marsh. However, field reports examining the spatial differences and controls of microbial biomass and

Previously Unrecognized Land‐Use Control on Deep Soil CO2 Sink

open access: yesGlobal Change Biology, Volume 32, Issue 10, October 2026.
Transport‐limited, boundary‐conditioned bidirectional exchange of topsoil‐respired CO2 drives CO2 accumulation in less bioactive subsoils in concentrations that cannot be explained by in situ production alone and far exceed atmospheric boundary concentrations, revealing a production‐transport imbalance and a potential land‐use‐sensitive pathway for ...

Insecticidal efficacy of Cleistopholis patens (Benth) against Sitotroga cerealella Olivier (Lepidoptera: Gelechiidae) infesting rice grains in Nigeria

open access: yesJournal of Crop Protection, 2016
New sources of botanical pesticides in the management of Sitotroga cerealella (Olivier) infesting rice grains are indispensable in farmers’ quest towards achieving maximum protection of their rice produce.

Transgenic Mixed‐Linkage‐Glucan Enhancement Affects Root Characteristics and Decomposition in Soils of Contrasting Vegetation History

open access: yesGCB Bioenergy, Volume 18, Issue 10, October 2026.
Incubations with fine and coarse roots of transgenic and wild type bioenergy sorghum showed that transgenic roots had higher content of mixed‐linkage glucan and resulted in greater soil microbial biomass than the roots of the vector control plants.

Phosphorus addition shifts elevated CO2 effects on soil respiration from rhizosphere to root pathways in a mature eucalypt woodland

open access: yesNew Phytologist, Volume 252, Issue 1, Page 100-113, October 2026.
Summary diagram of the utilization of additional carbohydrates fixed under elevated CO2 belowground in natural low‐phosphorus (P) (a) and P‐fertilized (b) conditions. Soil respiration consists of heterotrophic respiration from microbial activity in bulk soil, autotrophic respiration from fine‐root activity and rhizomicrobial respiration driven by ...

Preservatives treatment and field test monitoring of spruce pole stock: CCA and fumigant treatments

open access: yes, 1990
The fumigants trichloronitromethane (chloropicrin) and sodium N-methyldithiocarbamate (SNMDC) were used to treat red spruce pole stock, either CCA treated or untreated, through holes bored through the pole's center.

Plant genotypic diversity and defoliation jointly shape root exudation, fungal communities, and carbon and nitrogen cycling

open access: yesNew Phytologist, Volume 252, Issue 1, Page 324-339, October 2026.
Experimental design. Summary Intraspecific plant diversity is a major component of community diversity, yet its role in shaping plant–microbial interactions and soil functioning remains poorly understood. In particular, plant genotypic diversity may modulate ecosystem responses to defoliation, a key driver of ecosystem processes in grazed systems.

Ethylene dibromide-a fumigant for the food industry.

open access: yes, 1955
The use of ethylene dibromíde as a fumigant and particularly in combination with carbon tetrachloride has been known for the last 3 decades. Recent investigations have shown that it is equally efficient for controlling insect and fungal infestations in
