Downward Mobility of C-14-Labeled Simazine in a Bermudagrass System vs. a Fallow Soil System
CROP SCIENCE, 49(2), 704–713.
TL;DR:
Simazine is least mobile in bermudagrass during summer and most mobile in fallow soil in winter, indicating less moisture is available for downward movement during summer.

Impact of fipronil residues on mole cricket (Orthoptera : Gryllotalpidae) behavior and mortality in bermudagrass
FLORIDA ENTOMOLOGIST, 89(3), 293–298.
author keywords: Scapteriscus vicinus; fipronil metabolite; fipronil sulfide; fipronil sulfone; repellency
TL;DR:
Repellency of fipronil and its metabolites was significant as the majority of nymphs evacuated or died in the treated containers, but 35 of 37 nymphS were found alive in the non-treated containers.

author keywords: school IPM; IPM; German cockroach; Blattella germanica
MeSH headings : Animals; Cockroaches; Environmental Exposure; Insecticides / analysis; North Carolina; Pest Control / economics; Pest Control / methods; Pesticide Residues / analysis; Schools / standards; Time Factors
TL;DR:
It is demonstrated that an IPM program is an appropriate and preferable alternative to conventional methods of pest control in the school environment and most of the conventional treatments were unnecessary.

Interlaboratory comparison of extraction efficiency of pesticides from surface and laboratory water using solid-phase extraction disks
JOURNAL OF AGRICULTURAL AND FOOD CHEMISTRY, 51(13), 3748–3752.
author keywords: solid-phase extraction (SPE); pesticides; surface water; extraction; interlaboratory analysis; Empore disks
MeSH headings : Acetamides / analysis; Atrazine / analysis; Bromouracil / analogs & derivatives; Bromouracil / analysis; Chlorpyrifos / analysis; Chromatography, Gas; Filtration / instrumentation; Glass; Laboratories; Pesticides / analysis; Quality Control; Water / analysis
TL;DR:
In comparison to earlier work, recovery of these compounds using SPE disks as a temporary storage matrix may be more effective than shipping dried samples in a vial and other laboratories that had significant differences in pesticide recovery between the two water sources showed higher recovery in DW than in the SW regardless of the compound.
