I think it's authentic. Its light syrup with the same viscosity and color as several quarts I've gotten there or bought retail. But decreased potency due to age is a real possibility.

Here's another project with materials from that re-use site. (photo). Salvaged Rustoleum red primer and white topcoat. Thinned and filtered through double HF cone filters, it sprayed as well as fresh paint. Now 2 years later no problems noted.

Has it been dry where you are in Calif? I have found on a couple of occasions and confirmed through a company rep - during dry times when growth is reduced because plants have gone in survival mode that Roundup does not work nearly as well as when it is quite moist and growth is normal to heavy. Same thing in early winter and spring when temperatures are not warm enough.

So, it would be considered a broadleaf? Spray with 2-4-D. Won't harm grass.

Yes. 100+ weather day after day, low humidity. Also heavy smoke from the fires 100 miles away, to the point of quarter mile visibility at times and continual sore throat. (Photo).

This evening I'm going from home in the Central Valley over to the ranch (orchard) 10 miles inland from the coast. Weather there blows in from the ocean and I'll experience clean air for the first time in days.

I think your explanation is accurate, thanks!

2-4-D won't interfere with starting new lawn there? Tell me more!

I mowed it then hit the new leaves with Roundup mixed 50% stronger than label recommendation, with a tablespoon of Dawn dish detergent per gallon. I applied the third weekly application today. Tiny starts of Oak and Blackberry look sick, the Ivy looks slightly dazed but not killed. I do think few to no new leaves appeared since last week's application. This mix is effective against Oak and Wild Blackberry at the ranch but this city Ivy seems a lot tougher.

they would rather see it used per label directions. Applied Environmentalism.

I don't want to be the federal EPA police but I would not post and thus advertise that you are not following herbicide label directions.
In one post you state that you mixed it at 50% stronger than label recommendation then in another post you state that they would rather see it used per label directions which you admit you do not.

As to using a herbicide at a concentration higher than "label listed" not only is it a violation of federal law but mostly likely of your state as well (in California it is clearly a violation of state law) to not follow the label directions. Those labels are EPA approved at the application dilution numbers for those types of vegetation. Any use other than in accordance with the label is a federal offense. Fines are not cheap and in some instances jail can be indicated.

Even if you subscribe to the theory that no one will pay attention to you the little guy and your violation there is the following:
On top of that; using a concentration higher than label listed will often cause a failure of the herbicide to work as advertised. The old adage of "if a little is good then more is better" does not apply to use of chemical herbicides. The herbicides that have been discussed here are translocated herbicides. There is a required biological interaction in the plant that has to occur to have effective kill. These herbicide must be translocated into the roots or the plant will not die and thus you have wasted your money and time. Rates that exceed label directions can prevent translocation from happening.

In addition there have been several posts saying what dilution ratios that specific poster is using. The numbers that are on their specific label might not be correct for you and your label of the same chemical. The concentrations of Glyphosate that you can buy vary significantly. The oz per gallon that you can use to get the correct concentration 1% 1.5% or 2% thus will change. Read your own chemical label to verify the correct mix ratio for your application. Yes we need to read the directions.

That has to be tough! Enjoy the fresh air while at your ranch!

Silvic thanks, I'll keep your advice in mind.

Glyphosate is a weedkiller so pervasive that its residues were recently found in 45% of European topsoil and in the urine of three quarters of Germans tested, at five times the legal limit for drinking water.

Since 1974, almost enough of the enzyme-blocking herbicide has been sprayed to cover every cultivable acre of the planet. Its residues have been found in biscuits, crackers, crisps [potato chips], breakfast cereals and in 60% of breads sold in the UK.
EU on brink of historic decision on pervasive glyphosate weedkiller | Environment | The Guardian

Oklahoma News:
"If you go test your Cheerios, you'll find glyphosate which is the active ingredient of Roundup," said personal injury lawyer Noble McIntyre. "It's in Cheerios, Pop-Tarts, anything that's a food substance you now have glyphosate in that product."

According to a class-action lawsuit filed in May, an arm of the World Health Organization labeled glyphosate a "probable carcinogen."

"It's this simple: glyphosate is a chemical, it's absorbed into the plant, if you wouldn't put it in a glass and drink it, then you probably don't want it in your food eating it," said McIntyre. "You have to look at what the science says, and the science [is] starting to trend toward this is not something you want in your food if you're wanting to be healthy."

Some frightening facts about glyphosate:
It's highly persistent. U.S. Geological Survey data shows that glyphosate is present in more than half of all surface waters, soil, and sediment. Aminomethylphosphonic acid (AMPA), its degradation product, is even more commonly detected, showing up in more than 80% of wastewater samples collected at municipal treatment plants.
It's killing oﬀ our precious pollinators. Monarch butterflies are literally dropping like flies, with a shocking 81% of them having disappeared as a result of glyphosate exposure, according to researchers from Iowa State University (ISU). Glyphosate destroys the insect逞ｴ vital food source, milkweed, leaving the creatures to fend for themselves. Translation: they eventually starve to death.
It's destroying people's guts and immune systems. Glyphosate is a registered anti- microbial agent that annihilates organisms, both good and bad. When it enters your gastrointestinal tract, glyphosate not only destroys protective organisms like bacillus and lactobacillus, it also inhibits the growth of new protective organisms, leaving your body vulnerable to pathogenic invaders and bowel diseases like leaky gut syndrome.
It's even more toxic in combination with the other chemicals found in Roundup. Dr. Robin Mesnage is a scientist at the acclaimed International Agency for Research on Cancer (IARC), a division of the World Health Organization (WHO). He's also a leading expert at King's College of London's Department of Medical and Molecular Genetics and recently declared glyphosate to be definitely genotoxic, meaning it causes cell mutations.
Dr. Mesnage added that: glyphosate is everywhere throughout our food chain in our food and water. The lack of data on toxicity of glyphosate is not proof of safety and these herbicides cannot be considered safe without proper testing. We know Roundup, the commercial name of glyphosate-based herbicides, contains many other chemicals which, when mixed together, are 1,000 times more toxic than glyphosate on its own.

Understanding the Dangers of Glyphosate (& How to Minimize Exposure)

ABSTRACT

Glyphosate (GLY) is a herbicide that is widely used in agriculture for weed control. Although reports about the impact of GLY in snails, crustaceans and amphibians exist, few studies have investigated its sublethal effects in non-target organisms such as the honeybee Apis mellifera, the main pollen vector in commercial crops. Here, we tested whether exposure to three sublethal concentrations of GLY (2.5, 5 and 10 mg l−1: corresponding to 0.125, 0.250 and 0.500 μg per animal) affects the homeward flight path of honeybees in an open field. We performed an experiment in which forager honeybees were trained to an artificial feeder, and then captured, fed with sugar solution containing traces of GLY and released from a novel site either once or twice. Their homeward trajectories were tracked using harmonic radar technology. We found that honeybees that had been fed with solution containing 10 mg l−1 GLY spent more time performing homeward flights than control bees or bees treated with lower concentrations. They also performed more indirect homing flights. Moreover, the proportion of direct homeward flights performed after a second release from the same site increased in control bees but not in treated bees. These results suggest that, in honeybees, exposure to levels of GLY commonly found in agricultural settings impairs the cognitive capacities needed to retrieve and integrate spatial information for a successful return to the hive. Therefore, honeybee navigation is affected by ingesting traces of the most widely used herbicide worldwide, with potential long-term negative consequences for colony foraging success.

Look for a map of U.S. cancer deaths. Then look for a map showing counties with the most agricultural activity. Then ask yourself why there should be more cancer deaths in farming regions.
