Tomato Disease-more info on Early Blight

Early BlightSomeone replied to my last post on Early Blight, “Will this contaminate the soil (for next year)?” Great question. Here is more info on this subject.

If you have a garden, it’s pretty much in the soil. One key is to provide a barrier between the soil and your plant, hence I add straw as a mulch around them to act as a barrier and use fungicides to catch it early or before it starts.

Some years are better as they are drier but when you have a wet summer, it can be a problem. I’m not sure if you took out the soil if that would help because who can remove all the soil? Unless you put them in pots-maybe that would work.

You should consider crop rotation, not growing in the same spot for 2 years and then coming back to it 3 years later. Crop rotation is used to control diseases that can become established in the soil over time. Changing your tomato crops to a new bed or area tends to decrease the population level of the pathogens.  That is why I have 3 sections in my garden so I can rotate the tomatoes to a new section each year. If you have raised beds, you could rotate the tomatoes to a new bed each year coming back to the original bed 3 years later to get the same effect.

I don’t look at Early Blight as a major killer of tomato plants if we do close monitoring and take action. By using fungicides early on and crop rotation every year, we can usually control it.

Also good clean-up in the fall after the garden is done is important. Do not compost the dead plants but bag them and put in the garbage.

Tomato Disease-Early Blight

early blight_plant

This is a tomato with severe Early Blight. Notice it has worked it’s way up through the plant. I should have removed the diseased leaves while it was till on the bottom leaves and then sprayed with Serenade. I may not be able to save it.

 

Early Blight is a bacteria that lives in the soil and when the rain splashes the soil up on the lower leaves, the bacteria gets on the plant. It is a fungal disease. It starts as some yellow mottling on the lower leaves which left unattended, then proceeds to work its way up the plant branch by branch on the leaves as shown on the photo above. It is contagious to the other tomato plants next to it so you should get on this pronto if you see any sign of it. Some tomato plants are more susceptible to it as well.

With all this cool rainy weather (we got 1″ on Tuesday night!) I have noticed more plants starting to get it especially as the season goes on. The older plants (just like people) get more susceptible to diseases as they get older. Here is a closeup of what it looks like on the leaves.

tomato plant trimmed

Tomato plant trimmed off of all diseased leaves-notice there are hardly any leaves

If you see any of this going on, you should immediately trim off all the branches that show signs of it. Be sure to disinfect your cutting trimmers between plants so as not to spread it. Your plant may not have many leaves  left like this one.

bleach water

Use a 10 % bleach solution in water to disinfect trimmers

I use a small container, pour some water in it to cover your trimmers and put some bleach in the water – 10% is good. But I don’t measure. I just pour some in-much less than if you were to put it in your laundry. The key is to dip the trimmers and your hand or hand in glove into the bleach solution and dry them off before I go to the next plant so not to pass the disease on to a healthy plant.

tomato fungicides

I Start with Serenade and then move to Copper Fungicide if it gets worse. Be sure to wash your tomatoes really well if you use the copper fungicide. Both are organic but the copper fungicide is stronger.

After you’ve trimmed off all the bad stuff,  you need to spray with a good organic fungicide like Serenade to help slow it down. Also Copper Fungicide works but be careful using it. They are both organic fungicides. It’s best if you start the season spraying your tomato plants early BEFORE you ever have signs of Early Blight because then it’s a preventative but you may be able to control it if it hasn’t gotten out of hand, maybe not depending how bad it is.

Some of my plants (about 5 have it bad and don’t have many leaves left on because I trimmed them all off but they are loaded with tomatoes and the disease won’t hurt the fruit so I’m letting them stay in till I harvest and then I will pull the plant. It is interesting to note I only have one double row of tomatoes where it started with one plant and has now spread to 7 plants. (I already pulled out 2 others that showed it real early) Now I’m up to 7 plants out of 12 in the bed that have it. The rest of the beds look pretty good. I wish followed my own advice but was crazy busy in the garden this year and wasn’t paying attention.

How to deal with Early Blight

1. After you plant the tomato transplants and make a well and add your drip system (if you have one), put straw all around the base to keep water from splashing the soil up on the plants. This applies for either hand watering or even if you have them on a drip system because of the rain. And just because you put straw around your plants doesn’t mean it won’t get the disease, but it helps most plants.

2. Start spraying ALL YOUR TOMATO PLANTS with Serenade as a preventative right away. It has a bacteria that won’t let the Early Blight bacteria colonize on the leaves thereby thwarting the disease. Plus it doesn’t wash off as the good bacteria attach themselves to the leaves. Do spray about every 2 weeks even if it doesn’t rain as a preventative.

3. Once it starts raining, spray weekly. Be sure to add more straw if soil starts to show.

4. When you first notice the lower leaves yellowing, cut away any branches with the disease present.

5. Disinfect with bleach water between cutting limbs off different plants so not to spread it. You can use bleach water as mentioned above or alcohol on the blades. I use bleach as I have a lot of plants and it’s cheaper.

6. Spray immediately after trimming but I would wait to trim if rain is in the forecast for that day. I like to let the spray dry and let those good bacteria attach to the leaves so I don’t trim on rainy days.

7. If your plant continues to go downhill, keep trimming and spraying and of course you should be spraying ALL of your plants not just the infected ones. You can move to Copper Fungicide if you have to but I always take the least toxic organic methods first. And just because it’s organic doesn’t mean it can’t be toxic. Copper is organic and yet is toxic in great amounts but doesn’t last long on the plant so just wash your tomatoes before you eat them. You can also pull the plant early if it only has tiny fruit on it or wait if it’s loaded with bigger fruit but be aware it might pass it on to other plants nearby, especially those that it touches.

This might not help as much this year but keep this info for next year.

PS—Early Blight is not like Late Blight found on the East Coast. Early Blight if caught early can be controlled. Late Blight is always terminal for a tomato plant if it gets it. Luckily we don’t get Late Blight out here in the Southwest. It is currently confined to the North East part of the US.

I love my zinnias!

I love my zinnias in my vegetable garden. They are so beautiful and I love the new streaked varieties. They are a double zinnia and are so interesting to look at and the pollinators like them. I know if I was a bee, I would visit them!

They are also an edible flower-check out this article on eating them and recipes at: arcadiafarms.net

Himrod grapes productive this year

This year my grape vines are doing fantastic and I only have 3 plants. The variety I planted 4 years ago is called Himrod which is a cross between Ontario and Thompson Seedless Grapes and is an American seedless table grape. It is a great eating variety to grow for our Zone 5-6 areas.  It produces bunches of green seedless grapes with honeylike flavor and are juicy. The taste is divine!

Last year we had many hail storms that destroyed the grape leaves and bruised the grapes so badly that there was no harvest and that would have been our first year of harvesting. This year I covered them every time I thought a hail storm was going to hit or if I left the house and it paid off. We have so many grapes we are now drying some of them. It’s interesting that the beautiful green grapes turn brown when they dry. The raisins taste great – can’t wait to cook with them.

2014 Tomato Season in Santa Fe

closeup of virginia sweet

My all time favorite-an heirloom-a ‘Virginia Sweet’ tomato-a super sweet tomato worth the wait and weight.

Every year I try to get to the Farmers Market EARLY to sell tomatoes. Early to me would be end of July. Actually I would be delighted to even get to the market the first week of August. But no. Never. It’s not me I swear-I do my job. I get the tomato plants in the ground early enough. It’s THE WEATHER! Every year someone will ask me at the market how come they:

1. Don’t have any tomatoes or

2. Only have lots of green ones.

This year it’s the later because of THE WEATHER. So let me explain-No. 1 and No. 2 above and how both relate to THE WEATHER. This year we didn’t have a super hot June which was great because our tomato blossoms were able to set fruit in June. (If it’s really hot in June, then we experience blossom drop. Tomato blossoms won’t set fruit in temperatures 92°F and hotter.  They would have all dropped off all their little blossoms in our stinking hot Junes – hence no fruit and they grow more blossoms and set fruit up in July when it’s cooler but that puts us behind-see no. 1.)  But that’s not the case this year.

So on to no.2-we got LOTS of fruit now but they are mostly still green so we are still behind. Why? THE WEATHER! Now I don’t mean to pass the buck here as they say, but it’s true. July and now August this year has been delightfully cool and rainy. Daytime temperatures are cooler and nighttime temperatures are definitely cooler. Just like the old days with a real monsoon season. Now those of you new to the area (meaning you have moved here sometime in the last 12 years) have not really experienced the monsoon season, so enjoy it. Who knows when we will get another since we’ve been in drought like conditions the last 12 years.

Ok, back to why it’s THE WEATHER’S FAULT! So what’s happen is we have lots of green fruit but now we need some WARM SUNNY days to ripen the fruit. Even though the fruit can’t tolerate too hot of weather when trying to set fruit, after it’s set, they need warm sunny days to ripen up. All we’ve been mostly experiencing is very cool weather. Ah, what are we gonna do? It’s either too hot when they set blossoms or too cool to ripen.  Both scenarios make for a very late tomato season. Ah crumba!  I hope we get the warm days soon before fall comes as I have a ton of tomatoes on the vines! I sometimes wonder why I even bother and then I remember! I love tomatoes! I love trying new varieties! I’m a tomato addict!

Tomato Lady will return to SF Farmer’s Market this Saturday!

first tomatoes

Here are some of my tomatoes of the 2014 season. I’ll be back at the SF Farmer’s Market this Saturday, August 16th from 7-12 noon inside the building. Just look up high (above my booth) for my Tomato Lady sign to find me. I don’t have a ton of tomatoes yet and so they should go pretty quick and then I’ll be out but have many other items to sell like rhubarb, green and purple beans, Shishito peppers, various eggplants including the infamous fairytale eggplant and maybe some Kale. Hopefully next week I will have more!

But if you want tomatoes-come early!

Artisan Farm Tour-2014

It’s been a very busy summer for me. I’ve been preparing for my tour here on the property since spring. Nothing like having people over to get things done. I’ve had a punch list that I’ve chipped away at and finally got almost all of them done before last weekend when I had an educational tour for the Santa Fe Master Gardeners of my little Artisan Farm here in Santa Fe. Between the Home Grown Kitchen Garden & Coop Tour (different tour the week before) and my tour last weekend, I’ve pretty much been headless all summer. Now it’s all over and I can get back to a more normal pace. But wait, I’m getting ready to go to the SF Farmer’s Market! Always something. I guess I can rest in the winter! Here are some pictures of my Artisan Farm tour last weekend. The garden looks the best ever…
