Two resistant (R) populations from Hunan, China were confirmed to be at least 78-fold more than the susceptible (S) population. No difference foliar uptake 14C-labelled was detected between R S plants. However, higher level 14C translocation lower metabolism found Basal induced expression levels β-cyanoalanine synthase (β-CAS)...
Echinochloa crusgalli (L.) Beauv. (barnyard grass) is considered a noxious weed worldwide, and the most pernicious decreasing rice yields in China. Recently, E. has evolved quinclorac resistance, making it among serious herbicide resistant weeds The present study explored differences germination growth between quinclorac-resistant -susceptible collected Hunan Province. order of seven biotypes assessed, from high to low quinclorac-resistance, was: quinclorac-resistant, Chunhua, Hanshou,...
Asia minor bluegrass (Polypogon fugax) is one of the main weeds invading Chinese canola fields. The P. fugax resistant population SC-R, which survived quizalofop-p-ethyl at field-recommended rate (67.5 g ha-1 ), was collected from a field in Qingsheng County China. present study aimed to (1) characterize SC-R resistance pattern acetyl-CoA carboxylase (ACCase)-inhibiting herbicides, and (2) investigate mechanism this population.Dose-response studies showed that haloxyfop occurred population....
Nanopesticides are considered to be a novel and efficient kind of tool for controlling pests in modern agriculture. Covalent organic frameworks (COFs), with high surface areas, ordered structures, rich functional groups loading pesticides, class promising carrier materials that can used develop nanopesticide delivery systems. However, until now, only strong ionic interaction between the pesticide COF utilized achieve combination COF. On basis this method, charged molecules choice COF-based...
Eleusine indica has become a global nuisance weed and evolved resistance to glufosinate. The involvement of target-site (TSR) in glufosinate E. been elucidated, while the role nontarget-site (NTSR) remains unclear. Here, we identified glufosinate-resistant (R) population that is highly resistant glufosinate, with index 13.5-fold. Molecular analysis indicated mechanism this R does not involve TSR. In addition, pretreatment two known metabolic enzyme inhibitors, cytochrome P450 (CYP450)...
