We have had white flies on our tomato plants this year and can't seem to get rid of them. We have sprayed with sevin, Ortho Max, Spectrium, nothing seems to kill them. What can we use to get rid of them?

Been trying to get rid of the white flies with Ortho Max spray for vegatables, does that cause the leafs to turn brown.

Hi! Janet Efird, and Welcome to AMHD :)

I can help you with your question, but you kind of committed a forum faux pas by double posting :( . Do you want to stick with this one or the one at 8:46pm?

If you sprayed when there was bright light (direct or indirect) you could be experiencing a phyto-toxic reaction.

The first question about how to get rid of white flies will be fine..
Thanks Janet Efird

Whiteflies pierce the leaf to suck out the leaf's juices, leaving yellow dots. What you describe is “old age” especially if the leaves in question are at/near the bottom of the plant.

Hold off on the chemicals, and try a strong blast of water from the hose. Spray underneath leaves where the whiteflies tend to cluster. Do this daily until their gone.

Also make "sticky" traps from yellow cardboard smeared with petroleum jelly. They fly to it and get stuck.

Soapy water sprays are next. Use 1 teaspoon to 2 tablespoons of liquid soap per gallon of water. Use regular soap. Don't use soaps with any citrus in them as the citric acid can burn plants. Start with the lower amount and work up as needed.

Spray as often as needed. As with any spray you might want to test it on a few leaves first before you do any others.
Spray early in the morning before the sun heats up.

Next would be an insecticidal soap spray. It can be found at dedicated garden shops.
The insecticidal soaps are made from plant-derived fatty acids and target soft-bodied insects. Unfortunately, there's no way you can target the bad bugs without at least some effect on the good bugs.

If you can regularly monitor and tolerate some damage to your plants, over time Nature strikes a balance, with the good bugs coming in to control the bad bugs. Healthy plants will withstand insect attacks better than sick ones.

Plantpalshirley 'mite be on to something 'bout your other post. You usually don't want to spray leaves any time during the day or night. Best time is dawn or dusk

Not sure if you've visited the Upsidedown Tomatoes Thread (if this is 'bout toms), but there is a plethora :eek: of links 'bout toms.


See Ya round the compost pile
