Summary: Water quality parameters such as hardness, pH, alkalinity, turbidity, and TDS play a role in the effectiveness of herbicides in spray applications. Hard water with polyvalent cations can decrease the efficacy of weak acid post-emergence herbicides. Different approaches, such as water conditioning adjuvants containing nitrogen compounds like ammonium sulfate (AMS), ethoxylated amine surfactants, organic acids, and EDTA, have been proposed to overcome the negative effects of poor water quality. Understanding the impact of water properties on herbicide performance is crucial for optimizing herbicide use and avoiding excessive use, especially in regions with poor water quality.

Summary: In this study, we evaluated the effect of different sources of magnesium on ruminal fermentation, finding that the source did not significantly impact fermentation variables, but soluble magnesium concentration was higher for MgO compared to BLN. Buffer supplementation increased ruminal pH, acetate and branched-chain VFA proportions, and NDF digestibility, with interactions observed for propionate, butyrate, and NH3-N based on magnesium source. These results suggest that both MgO and BLN can promote similar ruminal fermentation at a concentration of 0.25% Mg, but buffer supplementation can have varying effects based on the magnesium source used.

Summary: This study investigates the adhesion of cold-sprayed copper particles onto differently adjusted hardness and roughness values of AISI 304 stainless steel surfaces. With SEM analysis and nano-indentation tests, it was found that grit-blasting causes severe plastic deformation of the surface, while vacuum annealing can restore the original hardness. The adhesion of cold-sprayed copper particles was found to be higher on roughened and softened substrates than on polished surfaces.

Summary: This study investigates the plastic strain distribution of cold spray Cu powders and coatings using electron backscatter diffraction (EBSD) analysis. It is found that more dynamic recrystallization and plastic strain release occur in the as-sprayed EP and GA coatings compared to the WA coating. The influence of recrystallization of twin grains in the GA coating on the ductility of the coating is discussed. The static recrystallization in the postannealing treatment is more prominent in the EP and GA coatings, supporting differences in dynamic recrystallization among the cold-sprayed coatings determined through EBSD analysis. The thermal conductivity of cold-sprayed Cu coatings is affected by recrystallization and strain release.

Summary: The study evaluated the impact of summer crops on winter weed emergence patterns and Ethiopian mustard planting on summer weed emergence patterns. Gompertz models were used to analyze weed emergence patterns, showing that winter weed emergence can be described using growing degree-day accumulation. Additionally, summer weeds may emerge during winter but are unlikely to survive, potentially reducing the seedbank before the summer crop season.

Summary: Water quality, including pH, hardness, temperature, and turbidity, can affect the performance of herbicides. Different herbicide chemistries and weed species respond differently to water quality factors. Weak-acid herbicides are more effective in acidic water, while sulfonylurea herbicides are negatively impacted. The temperature of the spray solution should be between 18°C and 44°C for optimal efficacy. Water turbidity has a severe effect on cationic herbicides and herbicides with low soil mobility. Adjuvants can be used to mitigate the negative effects of water hardness or pH, but their response varies.

Summary: The application of reduced rates of dicamba plus glyphosate on dicamba-resistant crops near peanut fields can cause off-target injury and yield reduction to peanuts. The severity of injury and yield reduction is greater when peanuts are exposed to the herbicide combination at 25 and 75 days after planting compared to 50 days after planting. Peanut injury can be used as a predictor for estimating yield reduction, and careful application of dicamba plus glyphosate is necessary to prevent drift or spray-tank contamination near peanut fields.

Summary: Growers in the US southeast are often advised to reduce nitrogen fertilization after peanut, but this is not supported by scientific literature. An experiment was conducted to evaluate nitrogen contributions from peanut residues to a subsequent carinata crop. The results suggest that peanut residues provide minimal nitrogen credits, supporting previous studies on the limited nitrogen contribution of peanut under humid southeastern US conditions.

Summary: The commercialization of crops resistant to 2,4-D plus glyphosate allows postemergence herbicide application. However, concerns arise regarding potential drift injury to peanuts grown near such crops. Field experiments conducted in 2019 and 2020 showed that peanuts were more sensitive to 2,4-D plus glyphosate exposure at the vegetative growth stage than at the flowering and pod development stages. The highest rate of 2,4-D plus glyphosate resulted in significant peanut injury and yield reduction.

Summary: Weed management in cantaloupe and other melon crops is crucial for maximizing fruit yield in California, where there are limited registered herbicides available. Independent herbicide trials conducted from 2013 to 2019 evaluated the effectiveness of registered and unregistered herbicides, as well as different incorporation methods, for weed control and crop safety in melons. The results showed that the combinations of halosulfuron, ethalfluralin, and bensulide consistently provided effective weed control compared to the control group. Mechanical incorporation of preplant herbicides yielded better weed control and higher crop yield compared to sprinkler irrigation. Early-season weed control, whether through herbicides or manual weeding, significantly increased melon yield in most cases.
