Help me identify early problem in earthtainer

ricklynchcore · July 11, 2012

I am in illinois, yesterday I sprayed my tomatoes with its weekly seranade rinse. This morning I noted some edge leaf curling and white brittleness on some leaf edges. Pictures below. It is not bad yet, but it is the edges of several leaves

I would say either heat stress or sunscald...maybe both.

Was it really hot when you sprayed? I would vote as Ken indicated - might also be spray residue caused some burn.

I sprayed at 7:00 am, but it was sunny and hot yesterday, anything I should do?

Maybe take a damp sponge and wipe those affected areas down and dry them. Not sure if it is doable (depending on the number of affected plants you have). Also not sure if it will have any real effect, but it can't hurt. (as long as you leave everything dry)

How big are the plants?

I had the same thing on my peppers.

Bio-fungicides don't usually cause leaf burn, did you add something else in the mix?

Worth1 · July 11, 2012

The reason I asked how big the plants are is because it looks like something I get every year from young plants.

It doesn't even come close to anything I have seen as leaf burn.

I would simply remove the damaged leaves and let new growth come out.

Nothing added to mix, just seranade. Plants all have tomatoes about 3/4 done, should see first harvest in 2 weeks or so.

Best thing is to water the soil, not the leaves...

riceke · July 12, 2012

I agree with Al@NC about watering the soil and not the foliage. Read somewhere where the theory of plants absorbing food through the leaves isn't as efficient as we thought and that there is more risk of leave burn and fungal disease associated with it.

I think Rick was spraying his leaves to prevent foliar disease. Tainers are bottom watered as is most SWC's. If he is spraying at 0700 it should have already evaporated by 0800 and sunscald should not have been a player.
Keep an eye on it and if it continues it could be the nutrients in the aggregate are getting depleted and you might want to add some to the reservoir using a liquid fert. Ami
