White "channels," on leaves...look like little paths
Q.The leaves of my plants have little curvy channels from the bottom of the plant up. The lowest leaves are turning yellow and brown. What is this and what type of treatment should I begin? I am harvesting fruit and have additional blooms.
A. Sounds like it might be whiteflies!
- Shake your tomato plant. If dozens of tiny white or light-colored insects break free, they are likely whiteflies.
- Look for whiteflies’ telltale trail of sticky white dew (called “honeydew”) on leaves, stems, and fruit.
- Check leaves for circular or spiral light-colored designs, which are actually strings of whitefly eggs.
Whiteflies suck juices from leaves, causing wilting, leaf damage, brown leaves, and stunted growth. If left unchecked, whiteflies can quickly defoliate your indoor tomato crop.
To control whiteflies, apply an organic insecticidal soap, such as Safer®, or horticultural oil, like neem oil.
