Professionals working in Agriculture & Natural Resources (ANR) take a close look at the needs of local farmers, consumers and the plants and animals living on Guam.
Agriculture professionals conduct variety trials to find the fruit and vegetable plants most suitable to the soils and climate of Guam. They meet with farmers to help them solve the issues of growing crops in a tropical climate.
Extension entomologists assist farmers in how to control crop pests as well as protecting native plants and animals from accidentally introduced invasive species such as the coconut rhinoceros beetle.
Extension plant pathologists look at the disease organisms affecting crops and other island plants including ironwood trees.
Horticulture professionals assist backyard farmers and community gardeners in starting and maintaining vegetable gardens and food forests.
In 2018, Cooperative Extension & Outreach established the annual agriculture survey of production outcomes, revenues, capital investments and needs for Guam farmers. This information is the foundation for development of Extension education efforts for all producers.

Coconut Rhinoceros Beetle
The coconut rhinoceros beetle (CRB), Oryctes rhinoceros, has been attacking coconut trees on Guam since it was first discovered on the island in 2007 and has proven to be voracious and tenacious. The coconut rhinoceros beetle, is a major pest of coconut palm, oil palm and other palm species. Palms are damaged when adult beetles bore into the crowns of palms to feed on sap. Tree mortality occurs when beetles destroy the growing tip (meristem). Immature beetles (grubs) do no damage. They feed on dead, decaying vegetation in breeding sites. Preferred breeding sites are dead, standing coconut stems, and piles of decaying vegetation such those left behind by typhoons or after replanting of oil palm plantations.
The links below provide more information regarding the CRB on Guam.
Native Plants
Native plants are important to the ecosystems of Guam for many reasons. They provide food and habitat for wildlife; medicine, food, and cultural resources for people; reduce contamination of reefs, rivers, and aquifers; influence the soil in ways non-native plants cannot; and some plants are not found anywhere else in the world. The links below take you to a PDF with information about the individual plants.

Plant Disease Diagnostics 2016
In May 2016, Extension and Outreach faculty member Dr. Robert Schlub in collaboration with the director of the Louisiana State Extension Plant Diagnostic Center, Dr. Raghuwinder Singh conducted a four-day diagnostic training workshop in an effort to strengthen the diagnostic capabilities of Agriculture Professionals in the region. Over the course of the training, agricultural professionals from Guam and the Northern Mariana Islands received classroom instruction, which was reinforced with plant disease specimen collection field trips and laboratory exercises. The training emphasized diagnoses based on field symptoms and those revealed through the use of a hand-lens.
