Managing Johnsongrass in Orchards with Ryan Hill (2025)
Johnsongrass can be a tough weed to control. Ryan Hill (UCCE Tehama, Shasta, Glenn) comes on the podcast to update us on the integrated year-round management of this perennial weed in orchards. UC ANR has great resources on distinguishing Johnsongrass and other young summer grass weeds. Johnsongrass identification photos can also be found on the podcast website. ANR also has a great guide to Johnsongrass biology and management.
Connect with a local UCCE weed expert! UC ANR has recently expanded their weed science team across the state. Ryan Hill (UCCE Tehama, Shasta, Glenn), and Clebson Goncalves (UCCE Lake and Mendocino) are based in the north state. In the northern San Joaquin there is Giuliano Galdi (UCCE Merced, Stanislaus, San Joaquin). In the central and southern San Joaquin there is Jorge Angeles (UCCE Tulare, Fresno, Kings), and Mandeep Riar (UCCE Kern, Tulare, and Kings). These advisors work in concert with statewide Cooperative Extension Specialist Brad Hanson.
Mention of a herbicide does not constitute a pesticide recommendation, merely the sharing of research results. Consult your PCA and read the pesticide label. The label is law.
