Does roundup- or any other of the weed killer sprays available in HD or other big boxes- have a negative effect on bamboo? Should they not be used for weed control around bambusas? Any experiences and feedback apprecdiated. Thanks.

As a rule Round Up is very effective in killing grasses. And bamboo is a "grass."

But also as a rule, it will not cause any damage if it does not come in contact with plant parts above the ground. And usually not even then, if it is kept away from the "green parts." So I would think you are safe if does not come in direct contact with any above ground bamboo, and only used minimally on the surrounding root zone areas. And of course be careful of wind drift.

(And note that there is now a Round Up (more expensive) that includes another agent for quicker killing. It is my understanding that with this "mix" it is important to kept it off of all plant parts.)

That would be Round Up ProMax Dean, it's almost the industry standard now. It utilizes a surfactant that gets through the leaves faster by breaking the surface tension. Round Up Quick Pro is the herbicide that contains Diquat, giving visible results by day's end.

Bamboo is really tough and I highly doubt that any inconsequential spray hitting it would damage the roots or corms. To eradicate it something like Garlon is needed.

I try not to spray round-up too often, but when I do, I never worry about overspray on things like bamboo, tree trunks, ground covers, succulents, cactus.

A lot depends on how strong the RU is. Highly concentrated solutions will do more damage from overspray than lighter concentrations.

I've not used the new mixtures.

Generally, it's absorbed through green tissues, leaves, stems, flower stems, and, I presume, green seedpods. It's not absorbed through roots, or brown/gray/black bark.

Bamboo is tough, and I doubt much will hurt established bamboo unless you really try. Recently planted bamboo might be different, though I'll leave that for the experts.

Some palms are seem very sensitive to RU overspray, particularly Dypsis baronii, at least when the plants are small.

Don't forget that many bamboos like Chusqueas, smaller Himalayacalamus and the like, are fairly dainty with green stems - and I would assume they would not appreciate even smaller amounts of accidental overspray. Not all bamboos are indestructible monsters. :)

Hmm. Your point is well-taken, though dainty doesn't always equal wimpy. Nutgrass isn't a monster, but it's still a monster.

Who says BS Man has weeds? The term weed is subjective, without any classification value, a plant that is a weed in one context is not a weed when growing where it belongs or is wanted. :interesting:

Study: Roundup and other pesticides directly linked to Parkinson's, neurodegenerative disorders

Thursday, November 01, 2012 by: Jonathan Benson, staff writer

(NaturalNews) The dangers associated with pesticide exposure are much more far-reaching than previously thought, as illustrated by a shocking study recently published in the journal Neurotoxicology and Teratology. It turns out that chronic exposure to Monsanto's Roundup formula, the active ingredient of which is glyphosate, as well as too many other common pesticides and herbicides is one of the primary environmental factors responsible for causing neurodegenerative disorders in humans.

As originally reported by Sayer Ji over at GreenMedInfo.com, the study brings to light the intricacies of how pesticide and herbicide chemicals induce cell death, which can eventually cascade into a host of chronic neurological illnesses such as Parkinson's disease and Alzheimer's. Even at levels significantly lower than the government-established safety thresholds, these persistent chemicals, which are routinely sprayed on conventional food crops and produce throughout the U.S., can cause permanent brain damage.

According to the U.S. Centers for Disease Control and Prevention (CDC), Parkinson's disease alone is the 14th leading cause of death in America. Figures from 2010, which are the latest available, illustrate a 4.6 percent increase in the number of deaths from Parkinson's compared to the year prior. And a 2007 report put out by the Parkinson's Disease Foundation (PDF) estimates that by 2030, the number of people worldwide with Parkinson's will more than double

In this latest study, Monsanto's Roundup was determined to be a primary factor in causing neurodegenerative diseases like Parkinson's, which is particularly interesting in light of another recent study which found that, even when diluted by a factor of 99.8 percent, Roundup chemicals are still fully capable of destroying both human cells and DNA. Together, these findings speak volumes in regards to rising disease rates, and lend solid credence to the notion that crop chemicals are a primary cause of chronic disease in today's world.

"A previously healthy 44-year-old woman presented with rigidity, slowness and resting tremor in all four limbs with no impairment of short-term memory, after sustaining long term chemical exposure to glyphosate for three years as a worker in a chemical factory," cites a 2011 case study published in the journal Parkinsonism Related Disorders about glyphosate's toxicity.

"The chemical plant produced a range of herbicides including: glyphosate, gibberellins, and dimethyl hydrogen phosphite; however, the patient worked exclusively in the glyphosate production division. She only wore basic protection such as gloves or a face mask for 50 hours each week in the plant where glyphosate vapor was generated."

If roundup is safe to use on bambusa, is it ok for humans? Saw this article.

I have a little experience with this as a state of florida licensed applicator for almost 10 years- Glyphosate will kill bambusa if sprayed on the leaves at an above average level(above 2oz per gallon) I spray 1 oz per gallon around all of my bamboo and have had no problems - I also spray it on my saw palmettos to kill all the weeds growing up through them as well as vines which are a major problem for me- the round up with surfactant is great stuff but steep in the price category - all u need is a few drops of dish soap in your round up to achieve the same result and it also cleans your nozzle as u spray which the new product does not do - lastly diquat is a great killer for certain things but adding it to glyphosate is not the best thing to do - it is for those impatient people who want to see instant results- unfortunatly most of the time it kills the receptors and does not let the glyphosate absorb and do the total kill- a good kill with just glyphosate takes about 4-6 days to show but then everything dies. Just my two cents- ive logged thousands of hours spraying it all and have no health problems to show even with prolonged skin exposure - I think as long as you dont inhale it or ingest it your good- working in a factory where it is produced may be another story though

You stated to observations that I was to pose questions.....since most gardeners do not get the same exposure that a manufacturing plant workers get (although I think that statement may be less factual than we think) the risk may be minimal. I think there may be other factors that bbring on Parkinson's than exposure to glyphosate.....I also question the source of the article, which may have other agendas.....

My experience is also having a QAL for the last 9 years. Might I say that the above statement is just about a perfect sumnation, sort of a CliffNotes concerning RU. Far too many homeowners are in a hurry to see results, thus the introduction of RU Quick Pro. I've used 1/2 - 1 oz solutions of the regular formula to eradicate weeds/grasses in juniper, ivy and jasmine, getting spray directly on the leaves without any visible harm but killing the intended weeds.

Far too many chemicals are sold in box stores that should not be. The simple fact is the majority of purchasers are ignorant about sprayer safety.

Whoo, hoo tell me about ignorant!

I remember the schmoe back in Diamond Bar who used to regularly spray STRAIGHT DIAZINON (from the Ortho bottle) onto the ground around his place to kill ants. "Well, it works!" he said, and, well, let's just poison you, your family, your dog, your cats and your family's family in the future in the bargain.

Hmm. I hope that study on the pesticides is half-baked . . . .

I have to agree with what has been said above. Using "generic" RU at even half the recommended dilution with a little added surfactant will kill most common weeds when small. It may take a bit longer, but is not only safer, but a lot cheaper.

The solution presents itself....train the gophers to apply the RoundUp and they will then contract Parkinson's.......how did we miss this?

BTW, Vincent, I apologize for the hijack....back to business,. I use RU on my garden, assiduously avoiding spry on the green leaves of any of the plants I wish to survive. So far, everything seems to work out Ok, except for the Organic Gardening Commune picketing my front yard.... :)
