Neighborhoods in Arden-Arcade and Rancho Cordova to be treated

Sacramento County is getting the jump on Japanese beetles. Before any new bugs are detected this spring, crews are treating neighborhoods in Arden-Arcade and Rancho Cordova in hope of breaking the life cycle of this highly destructive, invasive pest.
On Monday, Sacramento County announced it would start beetle treatments, the second year of an eradication program triggered by the detection of Japanese beetles in those neighborhoods. Impacted property owners will be notified in advance, the county says.
In past years, a few beetle sightings have triggered quarantines and spraying. But the last two years have brought a bevy of bad beetles.
“ Between June 4, 2020, and Aug. 9, 2021, a total of 231 Japanese beetles were trapped in the communities of Arden-Arcade and Rancho Cordova, Sacramento County,” according to the California Department of Food and Agriculture. “Unless emergency action is taken to disrupt the JB life cycle, there is a high potential for sudden future detections in Sacramento County and other areas.”
With shiny copper-toned wing covers and green heads, Japanese beetles look like little scarabs. They’re small – only 1/3 to ½ inch long – but are often confused with fig beetles or June bugs, which are both about twice the size of Japanese beetles.
So far, California has repeatedly fought off infestations of Japanese beetles, which are well established on the East Coast. But these Sacramento County bugs have been a challenge.
Traps were set out last summer in a 49-square-mile area of Sacramento County to monitor Japanese beetle activity. Instead of numbers going down, they went up.
“ (After review of data), I have determined that an infestation of Japanese beetle exists in the area, and poses a statewide significant imminent danger to California’s commercial fruit and berry production, residential fruit plantings, natural resources, and the economy,” wrote Karen Ross, California’s Secretary of Food and Agriculture.
“ Adults feed on the foliage and fruits of several hundred species of fruit trees, ornamental trees, shrubs, vines, and field and vegetable crops,” Ross said in her declaration. “Among the plants most commonly damaged are apple, pears, caneberries, pears, blueberries, cherries, plums, corn, rose, grape, crabapple, turf grass and beans.”
All that adds up to bad news if these beetles become established in the Central Valley.
Among the worst turf-grass pests, Japanese beetle larvae feed on the roots of lawns. Golf courses, parks and playgrounds are particularly susceptible and can act as nurseries for the baby beetles. The eradication effort includes treating lawns and ground covers with Acelepryn (also known as chlorantraniliprole).
The treatment areas include two islands in Arden-Arcade: An Edison Avenue neighborhood mostly between Becerra Way and Norris Avenue; and a larger area surrounding Watt Avenue from William Way to Marconi Avenue, including all of the Del Paso Country Club.
Likewise, two islands located within Rancho Cordova will be treated: The neighborhood surrounding Corvina Drive near Zinfandel Drive; and neighborhoods on both sides of Highway 50 from Mather Field Road to White Rock Road.
This eradication program is expected to continue through 2024 until state and county officials can determine if Sacramento County is Japanese beetle free.

Garden checklist for week of April 12
After these storms pass, get to work on spring clean-up.
* Weed, weed, weed! Take advantage of soft soil and pull them before they go to seed.
* From seed, plant beans, beets, cantaloupes, carrots, corn, cucumbers, melons, pumpkins, radishes and squash.
* Plant onion sets.
* In the flower garden, plant seeds for asters, cosmos, celosia, marigolds, salvia, sunflowers and zinnias.
* Transplant petunias, zinnias, geraniums and other summer bloomers.
* Plant perennials and dahlia tubers for summer bloom. Late April is about the last chance to plant summer bulbs, such as gladiolus and tuberous begonias.
* Transplant heat-resistant lettuce seedlings.
* Feed roses and other spring-blooming shrubs.
* April is the last chance to plant citrus trees such as dwarf orange, lemon and kumquat. These trees also look good in landscaping and provide fresh fruit in winter.
* Smell orange blossoms? Feed citrus trees with a low dose of balanced fertilizer (such as 10-10-10) during bloom to help set fruit. Keep an eye out for ants.
* Apply slow-release fertilizer to the lawn.
* Thoroughly clean debris from the bottom of outdoor ponds or fountains.
* Trim dead flowers but not leaves from spring-flowering bulbs such as daffodils and tulips. Those leaves gather energy to create next year's flowers. Also, give the bulbs a fertilizer boost after bloom.
* Mulch around plants to conserve moisture and control weeds. Avoid "volcano mulching" -- be sure to keep mulch a few inches away from tree trunks or the stems of shrubs. This prevents rot and disease.
