What is on these toms leaves? Notice the blisters and the curling? These are different plants, and they were all treated with fertilome triple action plus for what I thought might be aphids? Was I wrong, I only treated 3 days ago for this; and the directions say every 7 days or 14 days, 7 if badly infested. So; it has rained twice since then. Suggestions anyone?
Hmmm, mine do that from time to time. But its usually the lowest branches and leaves. I just remove them. How is the new growth? Is it blistered and curling?
In the 2nd pick...what is that white residue on the underside? Do you have whiteflies? When I see leaf curling, the first thing that comes to mind is a sucking bug(aphids, whiteflies, scale bugs, etc.). If no sign of those, then its usually a watering issue. You said it rained twice, did this happen about a day or 2 after the last rain? If so, they're probably just water logged and should be fine once they dry out a bit. The only other thing I could think is that the fertilome may have been too strong. What time of day did you spray the plants?
Ray: Those are the bottom leaves, and I suspected aphids, the fertilome action plus is an insecticide, miticide and fungicide with neem oil; do you think it is strong enough. My tom plants are pretty huge and some are finally getting yellow flowers on them. The thing is, this is not isolated to just one plant, there are at least 4 of them doing this, yes it has been raining a lot off and on and then its been hot. It says to treat with this mixture every 7 days; but, if it rains, doens't it get washed off?
If it's only the bottom leaves and the new growth isn't curled or deformed, I wouldn't worry about it. I remove most of my bottom branches anyways once they get close to 3 ft. My guess is that the rain drenched the soil which makes the bottom leaves curl. If it stays over watered for too long the bottom leaves will turn yellow and die off. Let them dry out a bit but not to the point of drooping. I would also closely inspect the bottom of each leaf to identify the bugs and how many before spraying again.
