Green Mulch From Invasives Offers Many Benefits, W. John Hayden Apr 2007

Green Mulch From Invasives Offers Many Benefits, W. John Hayden

Biology Faculty Publications

For the past several years, I’ve been clipping leafy branchlets of autumn olive for direct use as green mulch in my vegetable garden. In essence, I clip the shoots into segments ranging from 4 to 10 inches long, gathering the freshly chopped mulch into a wheelbarrow. I like to emphasize the youngest and leafiest stems, but since I am also interested in reducing the exotic plant’s biomass, I also clip woody stems up to a half inch in diameter. I then place the coarse mulch, leaves, young stems, and chopped woody branchlets, around my vegetable plants. I install the fresh …

Soybean aphid, Aphis glycines Matsumura (Hemiptera: Aphididae), reached damaging levels in 2003 and 2005 in soybean, Glycine max (L.) Merrill, in most northern U.S. states and Canadian provinces, and it has become one of the most important pests of soybean throughout the North Central region. A common experimental protocol was adopted by participants in six states who provided data from 19 yield-loss experiments conducted over a 3-yr period. Population doubling times for Þeld populations of soybean aphid averaged 6.8 d±0.8 d (mean±SEM). The average economic threshold (ET) over all control costs, market values, and yield was 273 ± 38 (mean …
