Unfortunately there has been another confirmation.. Obsoul33t spotted ditylenchus dipsaci's inside a stock of a friends outdoor plant the just collapsed..
These fuckers aren't going to be easy to beat, so far i haven't read anything promising its mostly prevention and crop rotation i'm reading..... Has anyone found any studies showing the elimination of stem nematodes through a tissue culture?
It's not on the list. My fear was that they were being used on nematodes, but they are not. Nemacur is the nasty one, which has now been banned,and supposedly can't be used after Oct, 2014. My hope is that that biological controls will be chosen over toxins/pesticides, like the one SS referenced in his last post, rather than Avid, pylon, and the "kitchen sink approach", referenced previously. I don't believe in dumping pesticides indiscriminately, as they have other, unwanted effects on the environment. The companies that are manufacturing these products are fighting tooth and nail to keep them from being banned. This comes before congress soon, and the lobbyists for the chemical companies have deep pockets.
I don't know. Try Googling it.
ok thanks. i was thinking i wasnt seeing something. a lot of these chems are intense regardless of being neonics,
Hey you guys are doing really well here now. Congratulations on the cooperative spirit that is now being fostered. Well done.
Nematodes don't have to be permanent.
Soil can be rendered completely nematode free with methyl bromide (shudder), it is absolutely necessary to hire a professional to use this shit though, it is truly deadly, wicked shit. It is also highly regulated, and only licensed professionals can get and use it.
There will be NO living things in the soil when they take the plastic up, except fungi and bacteria (the bacteria actually eat it up). No rodents, insects, no weeds. You can put other stuff under the plastic too, like tools etc. I don't use it, but I have seen it used many times, it really is the thermonuclear option for pest control.
For rescuing elite cuts that are infected with Ditylenchus, I am pretty sure that any of the more nasty organophosphate or carbamate products would kill them right off. Of course you would only use these on a cut that would be a mother of mothers of mothers, and not on a plant you were going to smoke (duh).
I think the most interesting way would be to inject a plant with an avermectin. Avermectins are produced by certain soil bacteria, and are widely used in human and veterinary medicine as antihelmenthics (worm killers). Very effective against nematodes. I think I read about banana guys using it this way to kill off some kind of savage banana tode. Kills mites too.
Once you had clean soil and cuts, strict adherence to cultural sanitation protocols would be crucial, given the highly mobile ways of the stem nematode.
Also, a good trick for testing plant tissues for nematodes is to kind of shred it up and put it in a shallow container of water overnight. Then scope the water. They tend to come out into the water if they are in the plant material.
I have to go read Storm Shadow's post on his use of chitin, I usually just skim this thread so I don't know the details. I am interested because the use of chitin against nematodes that I am familiar with is as a soil amendment. The chitin feeds fungi in the soil that eat, well, chitin. The increase in their population makes it hard for the tode eggs (shelled with chitin) to survive. It looked like SS is using it differently?
Well, the only other thing I have to say is that I think it would be very wise to follow Sam's advice to now turn your collective attentions to the other forms of dud that are out there. And don't just forget about the phytoplasma, if it is not yet a problem, it will be eventually. Any intensively grown crop will eventually meet up with every pathogen/pest that there is. All "legit" farmers know this. Prevention, preparation, vigilance, hey, it's not easy. If you guys develop a kind of rapid detection and response protocol for weed pests, you would be doing a great service.
Good work guys.

I first started playing with Chitosan as a SAR booster... I was buying in minimal amounts from
http://www.agrihouse.com/odc/odc label.pdf
1 ounce for $25 dosage is 1 ml per 1-5 gallon
I wanted to try some different dosages so I bought some Powder from China .. 1 Kilo delivered around $200 enough to make 5 gallons of the same product from agrihouse.. that would cost big money out here.. I love China!
http://medcraveonline.com/APAR/APAR-01-00006.pdf
Chitosan and its Oligosaccharides
I have some Nortica on its way... Is this dosage right or wrong?
35lbs bag makes a 17.5 gallon solution for drench .... Wet medium prior to planting anything and wait 2-7 days until New plants go in?

Nothing bought from China can be believed to be the real thing, or safe. Dog chews from China have killed thousands of dogs in the U.S. China is a totalitarian state that has no environmental rules safe guarding the public, and they counterfeit products for export. I wouldn't trust anything they sold.
yup obsoul33t is now the 3rd confirmed case of nematode dudding. his recent picture of microscope on instagram, he found em on a buddies sick outdoor plant. too hectic.
Found this from the 1960's, which is excerpts of a book on Nematodes, which claims hemp is vulnerable to rye stem nematodes.

It is still found in large university libraries, or for sale. Book is $312.00.
It also tells how to identify different varieties.
Also, read backwards from the point this link is to!!! Excellent info, that experts can get more from, than I.

Interesting information

Effects of Chitosan and Salicylic Acid on the Control of Cucumber Root Knot Nematode
The effects of exogenous chitosan(CTS)and salicylic acid(SA)on the control of cucumber root knot nematode and cucumber yield were investigated.The influences of CTS and SA treatment on the control efficacy of root knots and eggs,disease index,field control efficacy and cucumber yield were detected in pot and field experiments.The results showed that CTS and SA both possessed nematocidal activity,and had synergetic effects.In field experiments,a mixture solution of 150 mg/L SA and 100 mg/L CTS was effective in controlling cucumber root knot nematode,and root pouring treatment had better control effect than spraying treatment with 44.55% control effect and a 27.3% increase in cucumber productivity.A mixture solution of 150 mg/L SA and 100 mg/L CTS root pouring treatment had best control efficacy of cucumber root knot nematode and could increase yield.

Movento ...same stuff as Kontos.... the new label says
PESTS SUPPRESSED Nematodes
I stopped using all my strong chemicals when I realized I had no Micro Mites of any sort anymore...and I had a sudden increase in DUDS for the next year or so...
Kontos was the Knight in Shining Armor against Broad Mites and company .... Now it can help reduce the damage by this worm...this stuff is magic in a bottle!
http://www.growingproduce.com/nuts/the-dangers-of-nematode-damage/
Nut trees infested with nematodes experience reduced growth and yield, according to the University of California. These microscopic pests feed on plants’ roots, prohibiting the plant from absorbing the nutrients and water out of the ground. With nematode pressure, trees cannot grow and produce at their full potential. Growers cannot see the nematodes, but the damage and gradual reduction in production that occurs with nematode pressure are both hard to miss.
Tim Weststeyn, a pest control advisor (PCA) with Crop Production Services out of Vernalis, CA, consults on 4,000 to 5,000 acres of tree nuts. Weststeyn is currently treating for high ring nematode pressure in some of the almond crops.
Nematodes reduce the vigor of trees by attacking their root systems, making the tree more vulnerable to disease. Damaging diseases such as bacterial canker can be transmitted by nematodes. Weststeyn explains that the disease not only impacts the trees with nematode damage, but it is also highly contagious, posing a threat to previously healthy trees.
“You’ll have dieback in a tree, gumming, oozing, the limbs will suddenly die, buds will fall off the tree, they will look like they got burnt, and they pretty much die.” Weststeyn explains, “That’s the type of nematode damage and bacterial canker pressure I’m dealing with in almonds.”
Experience With Nematode Management
Many growers fumigate at planting to reduce nematode numbers, but Weststeyn explains that the fumigation only lasts for so long. Eventually, the nematode populations return, causing issues in the established crops.
“We don’t have many post-plant treatments that are reliable,” explains Andy Dugo, a PCA from the Escalon branch of Mid Valley Ag Services. “I see Movento as being one solution we’ve got that looks like it’s going to work.”
Movento (spirotetramat) from Bayer CropScience is an insecticide that can be applied as a foliar spray after crops are established. It is systemic throughout the plant to provide protection. The product’s two-way action allows it to move from the leaves to the roots, where it manages nematode populations.
Weststeyn and Dugo are both in their third year of treating established almond trees with Movento for nematode management. The biggest differences they’ve noticed? New growth and healthier trees.
“The tree has a lot of vigor,” says Weststeyn. “The tree doesn’t stress as bad.” Weststeyn also saw a better yield in the established orchards where he used Movento to treat for high nematode pressure. He explains that although it is too early to tell exactly how much larger the yield will be, he expects an improvement from 900 pounds of almonds last year to around 3,000 pounds this year.
“I see a healthier tree. It’s a greener tree,” says Dugo. “We are in our third year and we are seeing a big difference this year.”
Dugo attributes the healthier tree to a stronger root system, which he believes Movento allows the plant to establish. His experience has taught him that stronger roots grow healthier trees, which are more resistant to diseases.
Answers For Growers
“These field observations confirm what we have seen in our research and the research from Dr. Mike McKenry, a recently retired nematologist with the University of California-Riverside Department of Nematology,” explains Kevin Adam, Movento product manager. “Research has consistently shown Movento provides a 50% reduction in nematode populations for five to six months after application.
“Nematode damage is often overlooked because foliar symptoms from nematode infestations are not as dramatic as leaf loss due to mite feeding or nut damage from navel orangeworm, but the damage can be just as severe,” says Adam. “As growers manage their nematode populations, they will see a stronger, larger, healthier crop.”

it didnt list the stem nematode as one of the targeted species.
Stem Nematode is one that attacks and reproduces only on alfalfa
https://extension.usu.edu/files/publications/factsheet/alfalfa-stem-nematode08.pdf
sure its stem nematodes ? ..... ide imagine there many different species of nematodes the link i provided one the many available options in dealing with nematodes. it is not prejudiced to its target . their is also a health risk to human in its applications being a natural biological nematicide that contains a naturally occurring fungus, Paecilomyces lilacinus which can also target humans to some degree make sure to read n research before any application ... to be totally correct in diagnosis if you have dud get it tested for positive proof of correct nematode variety ... be safe stay free n ill chat ya later.
there are many others that site that same nematode on many species of crops. it is also one of the few nematodes that don live in the roots but rather the stem. its been shown to live in hemp (see locdawgs link) and has been documented in many others. google the latin name and youll see more info on its various hosts. i only point this out because im not sure a soil treatment wold necessarily be thorough in getting this ones eggs. i hope you dont take this as argumentative i just am trying to make sure we dont chase our tails. some of the journals listed it as alfafa only and i believe that is been widely contradicted at this point. if this is an effective treatment for the stem tode we all would be stoked to see it tried.
