Armyworms are Poised to Eat Your Vegetable Crops

Armyworms are Poised to Eat Your Vegetable Crops
They're back! Remember 2008 when armyworms marched from wheat into vegetable fields, eating everything in their path? Well, reports in western, NY are that populations of true armyworms in wheat are the highest they've been in years. True armyworms have also recently been reported in grass hay in Washington and Schenectady Cos., and in numerous crops, including sweet corn, Swiss Chard, and lettuce in Ulster/Orange Cos.

According to the NYS IPM Weekly Field Crops Report, the most common infestation sites for true armyworm larvae include dense fields of grasses, including wheat and other cereals, grassy forages, fields with rye cover crops and corn. Good grass control within and along field margins helps reduce the risk of infestations.

START SCOUTING NOW! When armyworms run out of food in wheat, cereal and grass fields, they will "march" into juicier crops, especially corn, and including vegetables. A 20- to 40-foot treated border around armyworm-infested wheat fields should prevent armyworms from entering other crops and minimizes the use of chemicals. Insecticide treatments for true armyworms are most effective if applied late in the day. Generally, true armyworms are easy to control with pyrethroid insecticides. It is important to detect problem areas early, while larvae are still small, because the large larvae do the most feeding and may quickly destroy whole stands. Armyworms feed at night, so check fields regularly for ragged holes chewed from the leaf margins, pellet-like frass on the ground and hidden larvae under plants and surface residue.

Some useful information from M. Montgomery, University of Illinois Extension follows:
"During the day, true armyworms curl up on the ground, typically beneath residue if they can find it. Larvae come in a range of colors (gray-green to tan). When residue is pulled back, larvae at first remain fairly still (typically curled up but occasionally sprawled out). However, in a short period of time the half inch to 1-3/4 inch long larvae begin to crawl rapidly looking for someplace else to hide such as additional residue or a soil crack. The true armyworm has a dark head capsule with a wide "V-shaped" marking between the eyes plus an orange stripe running down either side of the body. While some of these features may be shared by "look-a-like" larvae, true armyworm larvae can always be distinguished from other larvae by a series of dark bands/ diagonal black smudge-like markings on the prolegs (false legs) of older larvae. True armyworm larvae typically overwinter in the southern United States, and moths migrate back north each spring. Once here and once they have mated, females deposit eggs on the lower portion of host plant material. That host plant material can include corn, wheat, beans, cabbage, carrots, onions, peas, peppers, radishes, sweet potatoes, etc. Larvae feed for over a month and remove notches or large sections of leaf tissue on either side of the main veins. Left unchecked, all leaf tissue may be removed and plants may become soiled by frass (a polite term for insect feces). A few generations of true armyworm occur each season."

How to Take a Soil Sample

Soil sampling is an important part of managing your crops, but it's important to do it correctly. In this video created by the Eastern NY Commercial Horticulture Program, Vegetable Specialist Amy Ivy demonstrates how to take a soil sample.

For more information or to get soil sampling forms and supplies, visit Agro-One online.

Cornell Commercial Vegetable Guidelines Available

The 2019 Cornell Integrated Crop and Pest Management Guidelines for Commercial Vegetable Production are now available!

Written by Cornell University specialists, this publication is designed to offer producers, seed and chemical dealers, and crop consultants practical information on growing and managing vegetable crops in New York State. Topics include general culture, nutrient management, transplant production, postharvest handling, organic production, and managing common vegetable crop pest concerns. A preview of the Vegetable Guidelines can be seen online.

Highlighted changes in the 2019 Vegetable Guidelines include:
  • Updated pesticide options for economically important vegetable crop pests.
  • New pests: beet armyworm in beets; cabbage looper and tarnished plant bug in lettuce and endive; allium leafminer in onions; and Cladosporium, Cercospora, and Stemphylium leaf spots in spinach.
Cornell Crop and Pest Management Guidelines are available as a print copy ($41), online-only access ($41), or a package combining print and online access ($57.50). Shipping charges will be added to your order. Cornell Guidelines can be obtained through many local Cornell Cooperative Extension offices, or from The Cornell Store at Cornell University or call (844) 688-7620.
