This is the time of year when we start seeing worm populations increase in peanut fields. In fact, not long after my last “Peanut Update” post, I started finding more Velvetbean Caterpillars in peanut fields. The treatment threshold level of foliar feeding\u00a0worms in peanut is 4 to 8 per foot of row no matter which\u00a0one it is (armyworm, cloverworm, looper, velvetbean). However, properly identifying the caterpillar is important\u00a0in order to decide which\u00a0chemical to use.<\/p>\n

Velvetbean Caterpillar<\/figcaption><\/figure>\n

The Velvetbean Caterpillar has 4 abdominal prolegs. A pyrethroid insecticide will kill velvetbean caterpillars.<\/p>\n

\"Corn<\/a>

Pyrethroid insecticides also work on corn earworm.<\/p>\n

 <\/p>\n

Worms that a pyrethroid WILL NOT control:<\/strong><\/span><\/p>\n

\"Green<\/a>
Green Cloverworm<\/figcaption><\/figure>\n

The Green Cloverworm has 3 abdominal prolegs. Pyrethroids will<\/strong> NOT<\/strong> control Green Cloverworms. Products such as, Belt, Intrepid, or Spinosad should be used.<\/p>\n

\"Looper\"<\/a>
Looper<\/figcaption><\/figure>\n

Loopers have 2 abdominal prolegs. Pyrethroids will NOT<\/strong> work for Loopers. Dimilin, Belt, Steward, Intrepid, or Blackhawk are the recommended options.<\/p>\n

\"Fall<\/a>
Fall Armyworm<\/figcaption><\/figure>\n
\"Yellowstriped<\/a>
Yellowstriped Armyworm<\/figcaption><\/figure>\n

Pyrethroids will NOT<\/strong> control Fall Armyworms. Orthene, Prevathon, Dimilin, Belt, Steward, Lannate, Intrepid, or Blackhawk are the recommended options. Note: Orthene is only recommended for controlling\u00a0Fall Armyworm.<\/p>\n

\"Southern<\/a>

Belt is the only recommended product in the UGA pest management guide\u00a0for controlling Southern Armyworm .<\/p>\n

\"Beet<\/a>
Beet Armyworm<\/figcaption><\/figure>\n

Pyrethroids will NOT<\/strong> work for Beet armyworms. Prevathon, Dimilin, Belt, Steward, Intrepid, or Blackhawk are the recommended options.\u00a0If you’re not 100% sure which armyworm you have, it’s probably best to use a product that kills Beet Armyworms. Those products will work for Falls also. Belt is a product that works on\u00a0most all worm pest.<\/p>\n

I found this I.D. guide from the University of Nebraska to help you:<\/p>\n

Things to consider:<\/span><\/p>\n

Don’t apply an insecticide if it’s not needed and don’t use a pyrethroid if you’re not certain what the worm is. Pyrethroids only control three types of worms we have in peanuts. Make sure the worm is properly identified before making a choice on which product to use. If you have worms sensitive\u00a0and not sensitive to a\u00a0pyrethroid insecticide\u00a0and decide to use that product, you will need to be very diligent in checking\u00a0the field for the worms not controlled. Treat if the population reaches threshold level. Remember: if spider mites are in your field the pyrethroid insecticide will make the situation worse.<\/span> Fortunately, mites have not been an issue YET in peanut fields this year in our area, but that is something growers need to consider. Pyrethroids are inexpensive but, if it causes a grower to have to make a spidermite treatment, that\u00a0inexpensive treatment just became very expensive!<\/p>\n
