Somebody knocked on some wood because as of yet the fall armyworm run on the newly planted wheat that has hammered the guys south of us  has yet to materialize over a wide area. Diligence in checking your fields is still warranted.  Worm infestations are cyclical and full moon was a week ago, so if it is going to happen it will probably be in the next week or two..........but in all the fields I saw this week worms in wheat has not been an issue..... yet.

However.....all the fields of newly seeded alfalfa I saw did have some population of either worms, spotted aphids, or both.  Most were at a population that was over the economic threshold.  Watch your new alfalfa.

 spotted alfalfa aphids, need magnification to see spots, economic threshold on seedling alfalfa is 1to 3/plant.

The Field of Dreams was planted yesterday 9/30/10 using seed treated certified Endurance at 75 lbs./acre.

Moths are swarming everywhere. Will they still lay eggs and hatch worms this fall? Most look fairly young. How long does it take for them to lay eggs and regenerate worms.

Not all the moths you see flying are necessarilly "bad" moths, but some very probably are.
To use as an example the fall armyworm moth, it is usually a grayish, brown, with some blacking. The moth lays the eggs and 8 days to 2 weeks later out come the larvae (the worms that do the damage). The worms are ususally here for 3 to 4 weeks then go to ground and become a pupae for 2 weeks or longer, then emerge as a moth to begin the cycle over again. Fall armyworms can be present in Okla. well into Oct. and often times into Nov., so yes we might have another hatch yet this fall. The cycle often seems to follow or the moths seem to fly with a full moon, so we often see the larvae 2 to 3 weeks after full moon.....but not always.
