Now is the time to apply preemergent to stop Texas' winter weeds, plus get advice on adding compost to beds, protecting milkweed and more.

Nonstabilized SARS-CoV-2 spike mRNA vaccination elicited distinct antibodies to either Omicron variants of concern or preemergent sarbecoviruses.

Learn when to water, which grasses can go dormant, how to use preemergent, and why aeration with compost boosts lawn health in drought.

Long time listener, first time poster here. Novice native plant gardener in Zone 7a.Did not apply any preemergent to my front lawn this year to see what, if any, interesting natives would pop up. Have a decent amount of non native weeds (mostly chickweed and dead nettle). But these guys just started blooming over the last week throughout the yard.

Background: Metabolic perturbations associated with cardiovascular disease (CVD) risk factors prior to clinical disease manifestation may inform novel preventative measures. Here we characterize metabolome-wide associations with various cardiometabolic risk factors in an asymptomatic population to develop a mechanistic metabolic framework of preemergent metabolic shifts. Methods: Plasma was collected from a clinically healthy cross-sectional cohort (n = 361; Clinical Trials.gov ID: NCT02367287). Cohort mass spectrometry-based metabolomics (biocrates MxP(R) Quant 500 kits) were complemented with expanded lipidomic coverage for a sex/age-matched subset with LDLc difference > 60 mg/dL (n = 38). LDLc-focused partial least square regressions and discriminate analyses were performed, after false discovery rate corrections. Results: As LDLc levels increased, plasma sphingolipids and cholesteryl esters, and transulfuration products were higher, while ether-linked phosphatidylcholines serine, glycine, alanine, methionine were lower. The subset analysis further highlighted elevations in triglycerides and deoxyceramides with elevated LDLc. When adjusted for alanine concentrations, deoxyceramide concentrations increased as serine declined (p = 0.0012), and the deoxyceramide:ceramide ratios were higher in the high LDLc group (p = 0.039). Lower serine levels were also accompanied by parallel changes in glycine (p= 0.0004), and anti-parallel changes in transsulfuration pathway metabolites particularly when adjusted for ceramide levels. Notably, the alanine:serine ratio was more strongly associated with fasting triglycerides (r = 0.38; p

The monoclonal antibody, DH1047, broadly protects in vivo against preemergent bat SARS-related viruses, SARS-CoV, and SARS-CoV-2 variants.

If you have looked for an alternative to synthetic preemergent lawn herbicides that prevent annuals like crabgrass or foxtail, you may have noticed

Noticing some patches where this skinny green grass is peeking out. I can’t tell if it’s maybe just some wonky Bermuda still growing or another type of grass I need to treat for before next season. I did treat with PreEmergent a month or so ago. Not really getting any weeds which is great. Just patches of this other stuff. Thanks!by DarwinIThink

What do you guys think?by michaelseanc

My grandfather had his entire sodded in November (not the best time) with TifTuf bermuda. We couldn't apply preemergent at that time and now have many of the weeds in the photo. They began coming up in esrly to mid January. I've narrowed it down to rye grass, goose grass, barnyard grass or fox tail, but the only germination time that would make sense would be Rye grass. Ultimately want to know if this is a concern or if it will dye out with the heat and future preemergent apps will prevent it from returning.by MathematicXBL

Recent studies reveal that waterhemp can develop resistance to PPO-inhibiting herbicides from preemergent applications, not just postemergent ones. This poses new challenges for crop management.
