Greeting to all growers. First time on this site. This is my third year growing ag. Got about 400lbrs each year so far not trying to hard. Just pulled my biggest vine this year as new growth was yellow and all vine tips pointing upwards. See diary pic. Other plant in same patch is fine but is different genetics. Any ideas? No soil testing done.i have no svb or sqaush bugs here in kamloops yet.thanks Aussie78

Found your pic. Did you have cloudy sky and perhaps wet/cool weather for at least 3 or 4 days in a row?

Having had YVD several times in the past I’m not convinced that anybody really knows anything about where it comes from. I mean we know that bugs are a vector but I am certain that’s not the only way. In the soil, in the seed, airborne, it is out there somewhere. All you can do is keep growing and hope it doesn’t find you I. My opinion. Oh, and don’t use roundup it the patch. There’s no data on that, but I’m telling you now, that there is some link there.

Aussie78, you might have jumped the gun pulling this plant because we don’t have squash bugs or vine borers in BC, the only real pest to our giant pumpkins is aphids, so the likelyhood of YVD is zero.

New growth is almost always lighter green than older mature growth, and vines pointing up can be a combo of things including excessive nitrogen, or like pumpking is suggesting, some cool cool weather that had your vines looking for the sun.

Take some more pics of the vine tips from closer up. I’m not convinced that’s yvd. The clusters don’t look fat enough and they don’t appear to point straight up. Better to look close before pulling.

Good job Orangeneck, your advice is always solid and based on knowledge and experiences. Thanks for sharing.

The only known transmission source is squash bugs. This link to a study is probably the most comprehensive research that has been done on CYVD- https://getd.libs.uga.edu/pdfs/besler_kevin_r_201412_ms.pdf
Severe wilting is usually observed during the heat of the day if a plant has YVD.

Thanks all for the fast responses. The vine had stopped growing for the last 4-5 days and female blossoms had actually gone backwards and not opend at all. My other vine is in amazing growth and is in the same patch with same feeding watering conditions. I will rest that half of my patch this summer and hope to still get a pb this year. Not able to get any more pics as vine is gone already. Had some rainy days a while back but after days of sunny weather it just didnt recover. I have much to learn but looks like i have come to the right place. Thanks to all again and i look forward to sharing my progress with my other two vines. Will post a pic of my best remaining plant after work today

I had something similar three years ago and i let the plant go because there was a 20do pumpkin on the main.To my surprise the pumpkin slowed but never stopped.Every vine tip got leaves stacked in tight and then quit with the lightest lime green color.It looked similar to yvd but not exactly.( seen yvd many times ). The fruit got close to 400 inches,was really thin walled and had normal seed shells but every one was empty.

Interesting. Sounds very similar. This plant was a 2363 holland x 2009 wallace. It went from my biggest vine to my smallest vine in 5 days. Could be to much n as noted above. I may never know for sure. Fingers crossed my 4 dap works out. Its from a kline seed i selfed in 2017. Think i need to find some "proven seed" for next year. I plan to extend patch size and install misting in future.

Did you spray round up near your plants or did you make any fertilizer,nutrient applications with in a week or two of the symptoms showing up. There is no wilting of the plant, YVD would cause wilt in the sun.

No spray of any kind from me or neighbor. Only Mild application of p-k base feeding in last 2 weeks. Other plant in same conditions shows vigour and dark green in same growth stage. It is different blood though. No soil testing at all only ph in spring. No luck posting in diary though. Maybe its the site? Or my missing something

It takes a day or so for pictures to post to the diary unless you are a premium member, if that is what you are referring to.

Thanks steve for that link I’ll check it out.

Mine was on a 1781 zywiec. Was a real nice plant.No round up.no fertilizing different that the other plants.But it did look like what might happen if the plant sucked up a strong dose of roundup in a watering.

Iron deficiency? Thats my best guess.

Iron and other micro nutes have been applied in small amounts once per week all season. If it was available for uptake im not sure. Think i need to look into soil testing if its easy and not costly

Maybe some genetics are more susceptible to deficiencies and or imbalances of micros and ferts? Im a very basic grower of all things. Correct ph and good oganic matter is pretty much all i do. Leaves lots of unknowns

Sometimes these plants just do weird things. You may just have a genetic oddity. I have had many strange plants over the years. It sounds like Cojoe has had the same thing you have.

I usually give the oddball plants a shot to grow a fruit. Usually the fruit either abort after a short time or woh't set at all. Sometimes i have had a weird plant produce nice pumpkins. Cojoe said his plant grew a 400" pumpkin. Not too shabby.

I thought YVD started at one point then worked its way outward ,is this true or false,the diary image would say false
