South 89 Farms & Seed

Reports of armyworms in ryegrass appear to be wide-spread in the perennial ryegrass growing region. Armyworms don’t overwinter in northern MN and are blown into the area on southerly winds. Each year, several flights of the armyworm moths can be blown into the area. The preferred areas for armyworm moths to lay eggs are in grassy areas and ryegrass fields are a prime candidate for armyworm moths to lay eggs, especially lodged areas of the field. An adult moth will live up to ten days and can lay up to 2,000 eggs. These egg masses white in color and will contain between 100-200 eggs. These eggs will hatch into caterpillars in two-to-three days. These caterpillars will move through six instars in two-to-three weeks.
Egg masses and caterpillars have been observed at the U of MN Magnusson Research Farm in spring seeded ryegrass with wheat or late summer seeded ryegrass into fallow ground. It doesn’t appear to be any difference in numbers of egg masses, or caterpillars based on method of ryegrass establishment. It appears the most likely areas for armyworm moths to lay eggs are areas of lush vegetative growth and/or lodged areas in the field. With the increased armyworm pressure targeted insecticide applications probably will want to be on the upper end of the insecticide rate range. The insecticide will have to provide enough knockdown and residual for heavy infestations of armyworms in the lush foliage of mature perennial ryegrass. Talk to your seed agronomist for an insecticide choice that will provide good knockdown and provide residual control for armyworms. It’s important to control armyworms before swathing as if armyworms are in the field at swathing they will tend to concentrate under ryegrass swaths and can cause economic ryegrass seed losses, but also harvesting losses due to the worms going through the combine.
