It was hypothesized that, as the water treatment pH increased, there would be greater removal of herbicide from the soil in the rinsate. As pH of the solution increased, the equilibrium of the weak acid herbicide would be pushed towards … Continue reading →

To accurately compare emissions of a BE truck with that of a diesel truck, it is important to consider the upstream emissions associated with the fuel cycle in addition to the tailpipe emissions, to capture the emissions associated with generation … Continue reading →

Perennial weeds are usually most susceptible to glyphosate in the bud stage of growth immediately prior to flowering and in the fall when weed foliage is still green. Both stages represent times when weeds are translocating most of their photosynthates … Continue reading →

Spontaneous hybridization has, for instance, been reported in weedy populations of B. rapa growing in agricultural crops and in natural populations of B. rapa occurring near waterways. Second, flowering time has been extensively studied in B. rapa, and temporal clines … Continue reading →

Trees were manually edited with MEGA X . The DNA-A and DNA-B phylogenetic trees were rooted with the sequences of the genomic DNA of the OW monopartite begomovirus tomato yellow leaf curl virus and the DNAB component of the OW bipartite … Continue reading →

The study site varied in weed population composition each year. Based on non-treated plots, watergrass species infestation in 2019, averaged 10% abundance compared with 28% in 2021 . Sedge and broadleaf pressure were similar in both years. Similar variations have been … Continue reading →

The percentage of DEGs involved in cellular processes and response to stimuli were higher for upregulated genes, whereas the percentage of DEGs involved in biological processes, localization, signaling, multicellular organismal and developmental processes were higher for downregulated genes. Similar relatively … Continue reading →

Careful weed management during the season is important, but it must be followed up with off-season weed control as well. Short-season crops such as lettuce can provide opportunities for frequent cultivations and a rapid turnover of crops on the land, … Continue reading →

The third highest ranking concern of the Northern and Southern San Joaquin Valley and Low Desert regions was “water quality ”, while “regulations on water quality” was the third highest ranking concern for the Intermountain region. The third highest ranking … Continue reading →

Together, these rapidly expanding species cover more than 15 million acres throughout California . The phenological development of medusahead and yellow starthistle is in part what makes these invaders so successful. Medusahead, and particularly yellow starthistle, mature late in the … Continue reading →
