long gourd wrinkled tips

12 comments

I have taken a gourd, root, leaf, and soil sample into A & L Labs in London

Here are the results of the soil and leaf tissue test

If your out there Mr Vincent your input on the results and recomendations would be grately appreciated by all

Although not an expert, my LG also has a wrinkled and now rotted growing tip. According to my soil report I also had a deficiency in Calcium, Boron and Manganese. It is not Manganese. I'm pretty sure it is either/or Calcium and Boron. I know a lack of Boron can cause splitting in field pumpkins.

Was the tissue sample from a leaf or is it from the fruit it self? I wonder what the results would be if you sent in a tissue sample from the wrinkled up tip of the LG.

but his soil isn't lacking Brad. Sufficient B and too much Ca. All the nutrients are high or very high. the plants not picking them up.

iI took a vine in with leaves , soil, root, and a wrinkled tip gourd and this is what they recomended and did

Ian believes that it is blossom end rot and was pretty much bang on with the tissue test results before they did the test

He seams to think that thre might be too much plant to support a fruit demanding more calcium then the root can supply

I have since foliar sprayed 1 ounce of borax in 2 gal of water and 2 oz of superman and just watering with no K or Ca still going to apply sea weed and fish

The plants have now been prune to 4 ft x 12 ft and have new sets on all 5 plants

any other suggestions would be helpfull

The leaf blight disease issue has been delt with successfully by applying headline amp

it is a great product to have in your arsenal

Hopefully this will help

Sounds interesting. I wonder just what size of plant is needed to stop this from happening. Maybe growing it along the ground would help it root more & be able to pick up extra Ca. It would be nice to hear from our 2 LG guru's Al Eaton & Todd Kline on their thoughts.

 

Thanks John

If a gourd tip starts to 'wrinkle' and remedial action is taken and the progression of the 'wrinkle' is stopped, dries up and fruit remains firm ...can that gourd still be considered for competition?

I would say no Joel. The GPC rules are stated as follows; The tip of the gourd must be firm and in good condition. Those with a tip that is rotten, shriveled or rubbery should be left at home. If such a specimen does appear at a GPC site, it may be listed as damaged (DMG). That rule was brought in in hopes that if it was a genetic condition or genetic predisposition to the problem that it would eventually get weeded out of the gene pool.

GPC rules regulating long gourds section 7:

"The tip of the gourd must be firm and in good condition. Those with a tip that is rotten, shriveled, or rubbery should be left at home. If such a specimen does appear at a GPC site , it may be listed as damaged (DMG).

8) Recognizing that the perfect long gourd is a rarity, very minor surface cracks, soft spots and other flaws may be permitted at the discretion of the GPC judges.

The 'verbage' in the rules is 'rotten, shriveled or rubbery should be left at home'...what if there's no rot, theres no shriveling (starting to sound funny now;), and the gourd is firm? Not trying to be difficult but wondering if 'nipping the tip' at an early age of a pointy gourd (they seem to be the problem ones) may avoid the problem?...we do it on AG's if the blossom end looks like the're going to pose a problem. Will leave you with a scar on the bottom of the fruit but a solid fruit.

 

For the record i see non viable seeds in shriveled tips that would indicate a problem with pollen transfer or nutrient transport, not a genetic predisposition.

After the original tests and the discussion I had with Ian at A&L labs I did an extreme pruning on all 5 gourd plants , I tested the ph of my water on the advice of Joel Jarvis and found it to be over 8. I have since only applied water treated to the ph of 6.0. At the request of Mike ( Zeke) Demars I took another leaf tissue off of the same plant in on tuesday ( 3 weeks after the first test ) and I was surprized by the results. I have also noticed the shivelled tips are filling out and firming up on the gourds that had not already started to rot. I will be applying Boron and Manganese today.

I hope this helps this helps in finding a solution to the problem. I have a new opinion of soil and leaf tissue test and would be interested in seeing the results of other growers test with the same problems to compare

after going back over my soil test and seeing the manganese levels i have not applied anything as of yet

a little more computor time and knowledge before applying anything

From I have read on this B is very important to proper pollen formation and might be the cause of these shriveled tips and blossom end splits on the kins.

 

funny how the ph adjustment fixed the nutrient uptake of most but not the B, Mn or S

especially when the S and Mn are very high on the soil test.

    It is seed drying time of year. Keep your GVGO seed packs in mind. I am looking after sorting and sending out the packs this year. Lets all work together to make them great. Send in all kinds of seeds. Everyone is looking for different things in a seed pack. You must be a paid up member for 2020 to receive your seed pack. Here is where to mail them to: Jeff Warner 487413 Aidie Creek Garden Road Englehart, Ontario P0J 1H0 Send me an email or msg so i know something is coming and will let you know that i have received it. aidiejeff @ ntl.sympatico.ca

    John won the 150 square foot contest this year with a 1175.6 lb. pumpkin. The first one grown over 1000 lbs. in this contest. Congrats John!
