Three crop safety studies and two supplemental dose-response evaluations were conducted in 2019 and 2020 to evaluate the crop safety of the Israeli-developed PICKIT decision support system on California processing tomatoes. These studies were conducted at the UC Davis Plant Sciences … Continue reading →

M-209 T50 was affected by planting depth in 2019, at 79 DAP and 80 DAP for 3 cm and 6 cm planting depths, respectively. Full-season plant heights were not affected by PPB treatment, cultivar or planting depth either year .In … Continue reading →

The effects of herbicide application timing on Echinochloa densities in 2016 were only significant for T5; however, Echinochloa density was generally greater in plots with deeper-seeded rice. In 2017, Glyphosate alone reduced Echinochloa density by 30%, 31%, and 73% in 1.3 … Continue reading →

The four almond kernels that were tumbled directly in the [14C]- herbicide treated soil were rinsed with 20 mL of water. The rinsate was collected into glass scintillation vials and evaporated to near dryness using vacuum evaporation. 10 mL of Ultima … Continue reading →

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 →
