Glufosinate efficacy is inconsistent among weed species and under environmental conditions that favor rapid droplet drying. Surfactant-humectant adjuvants could maximize glufosinate by increasing wetting penetration into the leaf surface while decreasing evaporation rate (ER). However, there a lack of information in literature about interaction surfactant-humectants with glufosinate. The object...

This paper reports the first C. radiata population with resistance to glyphosate and multiple acetolactate synthase (ALS) inhibitor, imazamox. Two populations, one putative resistant (R) susceptible (S), were used in studies. Dose–response experiments performed evaluate factor (RF). Shikimic acid accumulation, 5-enolpyruvylshikimate-3-phosphate (EPSPS) ALS enzyme activities studied together che...

Abstract Italian ryegrass [ Lolium perenne L. spp. multiflorum (Lam.) Husnot] is one of the most troublesome weeds worldwide. also a grass seed crop cultivated on 50,000 ha in Oregon, where both diploid and tetraploid cultivars are grown. For this work, we will refer to species as multiflorum, since common names annual same species. A survey was conducted understand distribution frequency its s...

Abstract In the transition zone, turfgrass managers generally utilize dormancy period of warm-season to apply herbicides for managing winter annual weeds. Although this weed control strategy is common in bermudagrass, it has been less adopted zoysiagrass ( Zoysia spp.) due variable injury during post-dormancy transition. Previous research reported that air temperature could affect and crop safe...

Goosegrass (Eleusine indica) is one of the most serious annual grassy weeds worldwide, and its evolved herbicide-resistant populations are more difficult to control. Quantitative real-time PCR (qPCR) is a common technique for investigating the resistance mechanism; however, there is as yet no report on the systematic selection of stable reference genes for goosegrass. This study proposed to tes...

An investigation was carried out to monitor the escape and spread of oilseed rape (Brassica napus) transgenic plants and the introgression of transgenes to its closely related feral species in Japan. We screened a total of about 7500 feral B. napus, 300 B. rapa, and 5800 B. juncea seedlings from maternal plants in 143 locations at several ports, roadsides, and riverbanks. The presence of glufos...

Tomato serves as an important model organism for Solanaceae in both molecular and agronomic research. With whole genome sequencing in progress, there is a need to study functional genetics through mutant lines that exceed the practical limitations imposed by the popular research cultivar, Micro-Tom. This project utilized Agrobacterium transformation and the transposon tagging construct, Ac-DsAT...
