These insects curl up when disturbed and hide under the soil surface during the day. Young plants are clipped off at the soil surface. Plants grown on black plastic may be injured more severely. Use Sevin flowable or Diazinon granules or liquid(1).

Flea Beetles

Flea beetles leave small holes in the foliage. Use sprays of Diazinon(1), Sevin(0) dust or flowable, Methoxychlor(1) sprays, Pyrethrin(1) or Rotenone(1).


These 4 inch, green worms have a prominent horn on the rear end and can eat much foliage. The insects make a clicking sound when the plant is shaken. Use Rotenone(1), Sevin(0 to 3), Pyrethrin(1) and Bacillus thuringiensis.

Tomato Fruitworm

The worms may be green, brown, or pink with light stripes along the side and back. The insect eats holes in the fruit. Use Bacillus thuringiensis, Sevin (0 to 3) or Methoxychlor(1).


Aphids suck plant juices causing stunted and distorted growth. The leaves may be coated with sticky honeydew. Sprays of Rotenone(1), Malathion(7), Pyrethrin(1) or Diazinon(1) may be used.

Colorado Potato Beetle

The adults are yellow with black stripes and the larvae are red with black markings. Both stages eat the foliage. Use sprays of Diazinon(1), Sevin flowable(0), Pyrethrin(1) or Rotenone(1).
