Hi Again, Seams like I allways need your help!My straight eight cucumbers leaves are being eaten 1/5 of their growth and also have holes in them. My okra also have holes in the leaves, I have treated both with liquid sevin but when there is new growth,the problem starts again.Thanks

We're happy to help so feel free to drop by any time. I think you've answered your own question this time. Sevin is a broad-spectrum insecticide with some residual qualities. It will wipe out practically any insect in your garden and will protect the leaves you spray it on. But when new leaves emerge, insects in and around the plants know the leaves are unprotected and will nibble on them. Holes in cucumber and okra leaves aren't such a bad thing. Yes, the insects are feeding, but they aren't bothering the fruits of your plants. Without insects to pollinate the flowers you won't get cucumbers or okra so you don't want to overdo the spray. You especially don't want to apply Sevin when the bees are actively visiting your garden - it will kill them outright - and we really need to protect our bees. So, my only advice is to handpick any beetles or caterpillars you see on the leaves of your plants. Be sure to look on the undersides of the leaves because that's where the insects will hide. And remember that most plants can put up with holes in the leaves so try to accept some leaf damage. Best wishes with your garden!
