Step 1

Find out what is Bothering Your Tomato Plant

Step 2

Look on the upper part of the plant, leaves and green fruit to see if there are large amounts consumed as the hornworm will devour all of this. This caterpillar looking green hornworm gets its name from the fact that it has a black horn on the head.

Step 3

Aphids are little yellowish, rice shaped bugs that multiply quickly and eat the tomato plant leaves but the main damage they cause is the transmission of plant viruses.

Step 4

Thrips are brown little winged bugs that feed on the leaves as well and cause discoloration and damage to it. Spider mites are tiny, oval shaped, greenish yellow bugs that feed on the underside of the leaves and make webs on them causing discoloration and damage to them.

Step 5

Whiteflies feed on the underside of leaves and drain the tomato plant of their life if there are enough of them. Leafhoppers are brownish colored bugs that can jump and hide very well and prefer to suck the sap out of the plant or eat the tomatoes.

Apply Repellent at the Right Time

Step 18

First test spray a small portion of the plant or leaf and wait overnight to see how it fares.

Experiment with different repellents to see which one works best for your plants.
