leaf curl on two tomato plants

Asked July 21, 2018, 10:45 AM EDT

Of the 40 tomato plants in our garden, two of them have developed a leaf curl problem. The plants are green and have green fruit on them (pictures). All of my tomato plants have a little bit of early blight on the bottom branches (diagnosed by another expert on HGIC). The plants had a lot of healthy growth on the middle and upper branches so a week ago, I sprayed those with pre-mixed Daconil (0.087% Chlorothalonil) and it seemed to stop the spread of the blight. I cut off the blighted lower branches. I also use a foliar spray of fish emulsion and seaweed for fertilizer (hoping the smell deters bunnies and deer too). But unlike the early blight, this leaf curling appears on only a couple of the many tomato plants. None of the rest of the tomato plants exhibit it. Any suggestions? Thanks, you all are a huge help to us.

If only two out of many tomatoes are exhibiting this, it may be a varietal characteristic. A few varieties will respond to drought by curling leaves. If the plants are otherwise healthy, it suggests this.

However, please look over the diagnostic chart in "IMP Series: Tomatoes" for other possibilities: http://extension.umd.edu/sites/extension.umd.edu/files/_docs/programs/hgic/HGIC_Pubs/Edibles/HG56%20...
