Protecting the Pumpkin Leaves & Battling Powdery Mildew

The first week of August I always recommend an application of Actinovate and RAW Silica to the pumpkin leaves to help battle powdery mildew and other leaf diseases.  At this point of the season older leaves become vulnerable to diseases as they lose their resistance due to age.  Once these leaves get infected they become the base camp to spread spores to other leaves and then you can start getting problems.  Actinovate is a biological fungicide that I've found to be effective in helping keep powdery mildew at bay.  Once you have powdery mildew it can only help minimally, but if you start applying the end of July and beginning of August you'll find your leaves do considerably better to the end of the season.  You'll still get some powdery mildew, but it will be controlled much better than without it.

RAW Silica is a biogenic silica that works as part of the systemic resistance of the plant.  The plant takes the silica to the points of infection and crystalizes the cells around the infection to make it more difficult for the disease to spread.  Unlike most silica products on the market, the RAW Silica is Ph neutral so it isn't as high in Ph as most products which makes it more friendly to beneficial bio organisms.  You can't over use a biogenic silica, like you can a potassium silica, because the plant can only take in so much, so you can use it every week to get the multiple benefits of silica.

The Actinovate I applied earlier this week I noticed was past its expiration date so I reapplied from a new bag today along with the silica.

Watching the Details

I'm hating myself right now.  There wasn't any obvious signs, but this entire week I just knew in my gut that some thing was wrong.  In terms of growing weather, the weather has been very good all week, but both of my plants just haven't looked right.  Leaves were flagging more than usual on the 282 plant (this plant wilts much easier than the 1985 plant), my kids plants had some burnt leaves near the vine tips and the 1985 plant's leaves just looked a little off to me and growth seemed to be slowing down.  I was starting to wonder if all of the plants had some kind of disease, but there wasn't any real obvious indications as such.  Today I figured it out, but it had to hit me in the face.

Went out to the patch and plants looked like the picture to the left.  That is the 282 plant.  1985 wasn't quite as bad, but both of the kids plants leaves looked like folded umbrellas.  I immediately I turned the water on.  I knew it was either lack of water or the plants were going down from a disease.   It couldn't be anything else.  Within a few minutes I had the answer.  Lack of water.

I have two different irrigation systems.  The first comes on around 5:30 am and waters the plants under the canopy using a Dan Micro water system.  This gives the plants the majority of their water.  The other is an over the head sprinkler system that doesn't really water the plants much, but it mists the plants every 15 minutes to cool the leaves during the heat of the day and keep the humidity up a little.  I'm not sure what is going on, but the under the canopy watering system hasn't been working.  I'm not sure why, but I think this has been happening all week.  I've manually water under the canopy, off the timer this week when I've seen the plants wilt a little but I've assumed that it was going off each morning.  I don't have to do much vine burying these days so I haven't been in the dirt much.  I'm really upset with myself for not watching the water more closely, but I've never had problems with it in the past.

The damage from this probably won't just be lost pounds, but I would guess that deformaties will have formed in the 1985 plant from the lack of water and there will be some damage to the leaves.  I'm lucky the pollination on the 282 hadn't aborted.

The 1985 pumpkin had a circumference measurement that was four inches behind that of my 1421 pumpkin last week on the same number of days after pollination, but it was staying 4 inches behind.  That meant that although it started out a little slower than the 1985 it was keeping pace with it, which was impressive.  Then this week the growth started falling behind.  I wasn't sure if something like a disease that was causing problems or if the 1421 just really took off at this same point.   The answer was neither.  I was dehydrating the plant.

I'm on day 28 for the 1985 pumpkin.  Usually between days 26-30 a pumpkin really takes off in growth.  35-45 pounds a day is not unheard off.  I'm hoping I can get back to if I haven't screwed things up too much.  I've done a very good job this year with my fertilizer program, but you have to keep your eye on the balls for everything and not just one thing for pumpkin growing.


Gave both plants a foliar application of seaweed, humic acid, B-vitamins and yucca this evening.  B-vitamins and seaweed are good for stressed plants and help build resistance.  Plants are looking back to normal now after a good application of water this afternoon.

Cane Molasses for the Pumpkin Plants to Get the Biology Going

Interesting thing starts happening to the pumpkin plants this time of year.  It isn't something you can actually see, but an opportunity if you know what to do.  Plants and the soil biology have a symbiotic relationship.  The plant roots give sugars to the biology in the soil and in return the biology gives the plants nutrients in a form that they can use.  However, as the pumpkin starts kicking into gear and demanding a lot of the plants energy, the plant can start getting stingy with giving sugars back to the biology.  The opportunity at this time of year is to give the plants some RAW Cane Molasses which can give the biology the sugars they need, while they continue to feed the plant.  This keeps the soil activity going late into the season.

Nitrogen for the Giant Pumpkin Plants

This evening I did a soil application of nitrogen.  Most of the application was to the 1985 plant since I just recently pollinated the 282 plant.  On the ground I sprayed a mixture of RAW Nitrogen, RAW Cal/Mag and RAW Omina in spoon feeding quantities.  I saw how fast acting the RAW Nitrogen was this spring and I don't want a big spike in growth at this stage.  However, I do want to make sure the plants have adequate nitrogen to power growth for the pumpkins and I've given the plants very little nitrogen over the last month.

To the right is a picture of both plants.  In the far distance you can see the tarp that is covering the 1985 pumpkin.

Actinovate for the Pumpkin Plant

This morning I noticed what might be gummy stem blight on some of the leaves of the 1985 plant.  Not sure if it is that or just older leaves that got beat up in our 94 degree days this week.  I couldn't find my fungicide so I sprayed an application of Actinovate on the leaves of all of the plants until I can find some more time to dig around for my fungicide.  Gummy stem blight shows up as brown spots on the leaves that looks a little "gummy."  It can be a real problem if not controlled.  The TKO that I sprayed a couple of days ago should help to control it some, but I need a real fungicide to keep it in check.  Although, I'm not 100% sure if that is what it is, so I'll also watch the plant to see if more of it shows up.

Some Grandular Kelp for the Pumpkin Plants

This morning I gave both plants some granular kelp (0-0-1.5).  Kelp is a great source of hormones, potassium and micro nutrients.  Application rate was fairly small.  About 1/2 pound for the 1985 plant and 1/4 pound for the 282 plant.  I have some kelp mixed in with my myco that I put down at each leaf node as I bury the vines, but vine growth is pretty minimal these days as most of the vines are terminated and majority of the kelp application was done in the areas of the earliest buried vines.

282 Scherber Pollinated

I pollinated the 282 Scherber plant this morning.  A nice 5 lobe female at about 35ish feet out on the main vine (by far, the farthest and latest I've ever pollinated on the main).  I decided to self pollinate this one as I was once told that sometimes hard to pollinate plants do better with their own pollen.  This plant isn't actually a hard to pollinate one, but I didn't want to take any chances.  I took off one female on the main because I thought the plant was too small.  The next female was deformed.  The one after that I think the dog damaged.  The one after that the dog ate.  This one I'm hoping is the keeper.

Loading Up the Pumpkins

I'm going after a big pumpkin on the 1985 Miller plant.  Ada the pumpkin is growing nice, but I gave it a little nudge this evening with a foliar application of TKO.  I haven't used TKO in the past, but one of the RMGVG club members gave me some during the off season and I've wanted to try it for years, but it is kind of expensive.  TKO is a good source of potassium, but also contains phosphites that can help ward of disease.  The 1985 will be getting into its rapid growth phase so the extra potassium should help satisfy the pumpkin as it starts ringing the dinner bell.

I discovered last night that the 1985 plant has been getting under watered.  A setting on the under the leaf canopy irrigation system on that line was off so it wasn't getting nearly the water that it should have.  I'm impressed with the growth of the pumpkin on that plant knowing that.  It will be interesting to see how it does, now that it is getting more water.

The 282 female may be opening tomorrow morning.  Might finally be getting a pumpkin on that plant.   I sure hope so.  In preparation for that, in the fertigation bottle I put some calcium, RAW Full Up, RAW Humic Acid, just a little RAW Omina and RAW Yucca.  Like I previously mentioned, the goal with this is to help get calcium into the fruit in the first 10 days after pollination.

Compost Tea for the Pumpkin Plants

This evening I gave both pumpkin plants a drench of compost tea.  This compost tea was mostly made from alfalfa pellets which is a good source of hormones. I also put in a teaspoon of liquid seaweed and RAW Silica.  Just before application I put in some RAW Omina into the brew.  That should make the plants happy.

Orange Pumpkins & Other Things

To my surprise, when I went out today to check on the pumpkin I found a hint of orange on the blossom end of the pumpkin.   RMGVG club member Jack, two time Howard Dill award winner, would tell you that I always grow orange (and I do prefer the traditional orange pumpkin) but this year I figured my pumpkin to be more of an off white based on 1985 Millers that were grown last year.  The 1985 Miller pumpkins that I've seen pictures of had a orange stem end , but the majority of the pumpkin is something between white and a pale orange.  I think this one could end up being mostly orange however.  If you see orange at the blossom end this early it typically means a very orange pumpkin at the end of the year.

This evening I sprayed insecticide on both plants.  After talking with Joe about his mosaic problems for an hour yesterday, it reminded me that I need to be diligent with the sprays to keep in the game to the end of the season.  I lost both plants to yellow vine disease in mid-August last year and I don't want a repeat of that.

Some Multi-mineral for the Pumpkin Plant

Okay, this is one of those boring posts.  Did a foliar application of multi-mineral on both plants.  Blah, blah, blah, blah.  The reality is that part of pumpkin growing is being consistent and giving the plants what they need when they need it.

Had a really interesting conversation with Bryant of urbanfarmcolorado.com on that very topic.  If you ever want a fantastic raised garden installed (or any other type of garden for that matter), Bryant is your man.  Outside of a select group of giant pumpkin growers and soil scientists, Bryant knows about as much about growing as anyone.  The cool thing is that he isn't afraid to think out of the box and try new things.  He has some interesting ideas that he has the wheels turning on for plant and soil testing for optimal fertilization.  If he can get the ideas to work I'm the first one in line to buy the contraption.

Unbelieveable Luck

Went out at 6:30 this morning to pollinate the 282 Scherber pumpkin plant and the following is what I saw.  All of the flower petals were gone including the mesh bag covering the petals.  I believe the young dog at my neighbors house must have ate it off.  Next female is about 7 days away.  I can't believe the bad luck I've been having with this plant.

Thanks Joe & Lisa! Finally a Pumpkin Pic.

I've been in Canada for the last 8 days with my wife's family having a very nice time, but missing the pumpkins.  Joe was good enough to watch my plants again while I was gone and did some pollinations for me while I was away.  Very grateful for that.  My sister also helped with watering the plants in my absence.  A big thanks to both of them for their help.

The 1985 plant ran wild while I was gone.  Vines have popped up all over the place.  I was expecting that.  After terminating most of the plant, the stump had a lot of new growth popping up prior to my leaving and although I took all of that off before going out of town I knew that plant was looking for places to put all of its stored energy.  I'm hoping it can focus that energy into pumpkin growing and if it does we should be good shape.

This is the 1985 pumpkin named Ada after my niece.  It is 16 days old now and about about beach ball sized.  I like the look of that stem and the shape of the pumpkin.

The 282 plant will be pollinated tomorrow morning.  A month behind schedule so I'm praying this pollination takes.  Never would have thought we would be this far into the season without a pumpkin on the vine on this plant.  I've got a gut feeling this one could make up for lost time, but we are too far into the season now to see a state record off of this plant.  I plan to pollinate it with my son's1689 Daletas which has a nice pumpkin growing on it.

This evening I gave the plants a foliar application of fish & seaweed with some RAW Humic Acid and Yucca.

Pollination Aborted on the 282

The pollination didn't take on the 282 plant.  It will be another four days until the next female is ready.  A real bummer.  Have to hope that this one takes and we get a real mild September/October.

I continue to fertigate with the mixture of humic acid, omina, fulvic acid, and potassium.

Latest Photos from the Pumpkin Patch

Below are pictures of the 282 Scherber and 1985 plants.  The 282 is looking from the stump end of the plant and the chair (about 25 feet out) in the distance is where the pumpkin is growing.  The 1985 plant is looking from the side with the stump on the left.  We've had 3 days of very cool weather with heavy rain here in Denver yesterday.  Nice pumpkin growing weather after today however.

Feeding the Pumpkin

This evening I gave the pumpkin plants some RAW Omina, potassium, B-vitamins, Full Up and Humic Acid.  I'm using fertigation now for these kinds of fertilizers so I can give a small trickle of fertilizers to the plants through the irragation.   That allows me to fertilize more evenly and saves me some time.

After all the rain the 1985 pumpkin has really shined up and started to grow.  With warmer weather ahead, I'm hoping it will really put on some weight this next week.

Also sprayed some insecticide on the plants.

282 Scherber Pumpkin Pollination

Got this one in, just under the wire.  The latest pollination I've ever had for a competition pumpkin was July 10th.  That was my rookie year.  That pumpkin ended up at 755 pounds.  Finally got a pollination that will hopefully will be a keeper on the 282 Scherber plant.  Unlike the last one, this one has a good shape and four fully formed lobes.

Biotamax in the Garden

Today I sprayed the entire pumpkin patch, garden and lawn with Biotamax.  Biotamax contains trichoderma harzianum, trichoderma viride, trichoderma koningii, trichoderma polysporum, bacillus subtilis, bacillus laterosporus, bacillus licheniformus, bacillus megaterium, bacillus pumilus and paenibacillus polymyxa.  These soil probiotics can help eat bad fungi in the soil, produce plant hormones and help feed the plant.  I'm not sure that the effervescent tables will actually allow some of the benefical bacterial and fungi to survive, but I believe a good portion of them could live and the cost of a tablet is cheap (around $6) being able to treat an entire acre so I like to put one down every year.

I noticed that mushrooms were popping up in the lawn.  That is a good indicator that the environment in the soil could be right to produce bad fungi, so I figured now was a good time with the rain to spary down the Biotamax under the leaf canopy in the pumpkin patch.

Actinovate Iron & Some Azos in the Garden

Since it was raining I thought this would be a good opportunity to spray some Actinovate with Iron and some Azos under the leaf canopy.  Cool weather in Denver today with it only getting to about 70 degrees today.  Not much rain, but a fairly constant mist throughout the day.

Acinovate is a pretty interesting biological.  It is one of the few that I can think of that works in the soil and on the leaves to protect the plant.  Actinovate contains a patented beneficial microbe that suppresses and helps control a wide range of diseases, including black spot on roses and the late-blight that tomatoes can get.  I particularly like to apply Actinovate to the leaves of my pumpkin plants around the first week of August.  You will get a lot less powdery mildew if you apply at that time and at the beginning of September.

Foliar Multi-mineral & Fulvic Acid for the Pumpkin Plants

Today I took off the pollination on the 282 Scherber plant.  Hated to cut it off because I think it would have been my biggest 10 day measurement ever at its current pace, but when I took off the flower petals yesterday it was obviously herniated and as the pumpkin grew it would have easily blown.   Next pollination is going to be about 5-6 days.

Weather is going to cool down in Colorado over the next few days with a descent amount of rain, so I did a foliar application of multi-mineral with a touch of RAW Full Up (fulvic acid), RAW Grow and RAW Yucca.
