Seed dormancy, germination requirements, and implications of herbicides for Penstemon albidus and P. nitidus

open access: yesRestoration Ecology, Volume 32, Issue 7, September 2024.
Seed‐based restoration is dependent on seed germination, and poor germination can cause restoration failure. Many restoration failures can be attributed to a lack of knowledge of germination characteristics, species‐specific seed dormancy, or the effects of widely used herbicides on germination. White penstemon (Penstemon albidus) and Waxleaf penstemon

Rate and time of nitrogen fertilizer application for winter camelina

open access: yesAgronomy Journal, Volume 116, Issue 4, Page 1804-1816, July/August 2024.
Abstract Winter camelina [Camelina sativa (L.) Crantz] is a potential third crop to diversify maize (Zea mays L.)–soybean [Glycine max (L.) Merr.] rotations in the upper Midwest. Although generally considered a low‐input crop, empirical evidence suggests that it responds to added nitrogen (N) fertilization.

Simultaneous removal of mixed pesticides and natural organic matter from surface waters by nitric and chlorosulfonic acid functionalized powdered activated carbon

open access: yesJournal of Chemical Technology &Biotechnology, Volume 99, Issue 7, Page 1646-1659, July 2024.
Abstract BACKGROUND Several studies have addressed the adsorption of pesticides such as alachlor, acetochlor, metolachlor and fenthion from water and wastewater, yet the interaction of these compounds with natural organic matter (NOM) complicates their effective removal owing to competitive adsorption effects.

Recent developments in fluorine‐containing pesticides

open access: yesPest Management Science, Volume 80, Issue 7, Page 3065-3087, July 2024.
In the timeframe 2016–2022, approximately 77% of the 39 launched products (herbicides, fungicides, insecticides, acaricides, and nematicides) were halogen‐substituted and from these, approximately 64% were fluorine‐containing pesticides. Abstract To ensure ongoing sustainability, the modern agrochemical industry is faced with enormous challenges. These
