Southern nursery group shows growers how to get the biggest bang for their buck with weed control

Most of us are used to seeing weeds in our yards or flowerpots, but not in the plants that we buy in the store. Nursery crop growers and workers go to great lengths to make sure that the plants we buy are weed free when we pick them up. That service comes at a great cost to the grower, however, so Joseph Neal at NC State University sought to remove some of the burden by teaching nursery owners more efficient and economical ways to weed their container plants.

Weeds are a serious problem for nursery crop growers, not just because they reduce marketability of their container plants, but also because they can inhibit plant development. Just one large crabgrass plant in a container with Japanese holly, for instance, can reduce the weight of the holly by as much as 60 percent. Nursery crop producers use between three and six applications of preemergence herbicides per year, and often must still hard weed after that. The cost of hand weeding is between $500 and $4,000 per acre per year based on labor costs. Continue reading

Webinar on Phytophthora in nurseries, April 28

A Systems Approach To Producing Healthy Container-Grown Plants

Tuesday, April 28, 2015

10-11 a.m. PDT

Native plant nurseries are becoming increasingly aware of the risk of harboring plant pathogens, especially Phytophthora species, that have the potential to threaten the health of ecosystems.  In this webinar you will learn how to apply a systems approach to analyze your nursery production system and identify potential contamination hazards. You will also learn best management practices that will allow you to take corrective action and help ensure the health of your plants. The presenter will be Jennifer Parke, Dept. of Botany and Plant Pathology, Oregon State University.
