The Benefits of Clean Planting Stock

Healthy planting stock is key to the cost-effective production of horticultural crops such as fruit trees, berries, and grapevines. Healthy plants are easier to propagate, require fewer chemical inputs, and produce higher crop yields and better crop quality than diseased plants. Healthy planting stock is necessary for U.S. agriculture to remain internationally competitive and economically viable. Clean plant programs across the country support U.S. agriculture by providing healthy planting stock to get nurseries and growers off to a good start and allow them to continue to produce the highest quality product possible. In this issue of the NCPN Network News, we hear from our end users to better understand how important clean plant programs are to their success.
