Integrated Weed and Soil Management Using Soybean and Cowpea cover crops.

This project involves screening soy and cowpea varieties for cold tolerance, rapid emergence, and weed suppressiveness alone and in combination with non-legumes, to look for combinations that will both deplete the weed seedbank and build soil health.

Vinegar and Clove Oil: Potential Weed Control Tools

This project will look at these two products in terms of economic, practical uses in a wide variety of vegetable crops to determine optimal concentrations, spray pressure, adjuvants, weed species and stages of development. Robin Bellinder rbb3@cornell.edu 607-255-7890

Stale Seedbed Technique for Leafy Lettuce Production

A field study to determine whether rolling baskets or cultivating knives were better choice in stale-seedbed planted lettuce, and whether post-emergence cultivating was required. Rolling baskets performed better than knives, and post-emergence cultivation did not improve yield or decrease weeds. M McGrath mtm3@cornell.edu 631-727-3595
