Stock Plant and Tree Production: Weed Management in Citrus Nurseries

Hairy bittercress

All citrus nursery stock in Florida is raised in enclosed greenhouses. It is not uncommon for weeds to grow in containers, where they compete with citrus seedlings, and on greenhouse floors, where they can harbor pests and diseases. This new 7-page publication of the UF/IFAS Horticultural Sciences Department provides descriptions of a few commonly found weeds in citrus nurseries and good weed management practices. Written by Biwek Gairhe, Ramdas Kanissery, and Brent Sellers, this article is chapter 8c of the forthcoming Citrus Nursery Production Guide.

Identification and Management of Clustered Pellitory (Parietaria praetermissa) in Citrus Groves

New seedling emergence of clustered pellitory in a citrus grove.

In Florida, clustered pellitory is becoming a troublesome weed for citrus, especially from the winter through early summer. Inadequate management of this weed can result in its heavy infestation in tree rows and can interrupt the spray pattern of low-volume drip irrigation systems. This new 3-page publication of the UF/IFAS Horticultural Sciences Department will assist Florida citrus growers with proper identification of clustered pellitory and with adoption of adequate and timely strategies to manage this weed in their groves.
