Northern Nevada gardens and backyards: Controlling insects with systemic insecticides – Carson Now


Last week I wrote about soft versus armored scale insects. Soft scales exude honeydew, are protected by ants and can be controlled by systemic insecticides, some of which have the active ingredient imidacloprid. Armored scales do not emit honeydew and are not managed by an imidacloprid insecticide.

Imidacloprid is a systemic neonicotinoid insecticide that is designed to kill piercing/sucking insects via damage to their nervous system. Systemic means it is applied on the leaves, stems or as a soil drench and spreads internally throughout the plant. When an insect feeds on any part of the plant such as the pollen, nectar, flowers, fruit, leaves, or other plant tissues, it ingests the toxic chemical and dies.

Systemic insecticides can kill not only pests such as soft scales, but also their natural enemies and non-target/beneficial insects such as bees and other pollinators, including butterflies, moths and their larvae. They also can “adversely affect reproduction, growth, insect immune systems, learning, flying, or other attributes even at concentrations too low to cause death outright.” Native bees, who often nest in the ground, can be more susceptible than honeybees, particularly to soil drench applications. 

Systemic insecticides kill over time at a steady concentration, which can cause a longer toxic exposure. Although it is often suggested to apply in the evening when insects aren’t out, or after flowering season, harmful exposures can still occur. These chemicals can last for months or years in soil. They sometimes leach into groundwater but fortunately are usually only slightly toxic to fish. One application may provide season long control.

Chemical insecticides are always a last resort. The risks versus benefits must be carefully evaluated. A healthy thriving plant is one of the best defenses against scale or other insect damage. Good watering, the appropriate amount of fertilizer and maintenance keep a plant resistant to attacks. Predators, including lady beetles, bugs and lacewings, play an important part in pest management.

Plant a diversity of flowering plants to attract and feed natural enemies. Sometimes when you see scales on a plant, they may have already been parasitized by parasitic wasps. If a large number are parasitized, there are eggs in or on each scale eating away at them. Sometimes scales are no longer alive and do not require a pesticide treatment. Check before applying insecticides. Using tape traps to monitor crawlers will help you accurately time the use of horticulture oils, Neem oil or insecticidal soap. Dormant oil treatment on deciduous woody plants will help kill overwintering scale pests and reduce future populations.

Nevada troopers end 116 mph pursuit of speeding Camry near Battle Mountain

Nevada troopers end 116 mph pursuit of speeding Camry near Battle Mountain


A high-speed pursuit that began near Battle Mountain ended with an arrest west of Elko after troopers used a tire deflation device to slow a fleeing driver who later ran from his vehicle, authorities said.

On Thursday, June 4, 2026, around 1:30, a Nevada Highway Patrol trooper observed a white Toyota Camry traveling in excess of the posted speed limit near Battle Mountain in Lander County. When the trooper attempted to stop the vehicle, it accelerated to 116 mph. The Camry began passing on the outside shoulder, and the pursuit was terminated in the interest of public safety.

At 2 p.m., another trooper observed the Camry near Carlin on Interstate 80 as it exited via the Central Carlin off-ramp. The vehicle accelerated and traveled west on Chestnut Street, then went south on State Route 278 toward Eureka. The Camry traveled down a mine access road off State Route 278, and the trooper lost visual contact. Additional troopers responded and attempted to locate the Camry along the mine access road but were unsuccessful.

At 3:02 p.m., the vehicle was observed traveling northbound on State Route 278 while being pursued by the Eureka County Sheriff’s Office and Carlin Police Department. Troopers then pursued the Camry on Interstate 80 eastbound from Carlin as it traveled 115 mph.

Troopers successfully deployed a tire deflation device, also known as a Stop Stick, as the vehicle entered the Carlin Tunnel. The Camry slowed to about 80 mph after the left front tire tread separated from the rim. The vehicle continued eastbound on Interstate 80 toward Elko and slowed to 20 mph.

The driver exited the moving vehicle near mile marker 297, about one mile west of the West Elko (State Route 535) interchange, and the vehicle came to rest in the center median. The driver ran south across the eastbound travel lanes and entered the ranching area south of Interstate 80.

For the next 30 minutes, law enforcement pursued the male suspect on foot through various terrain west of the city of Elko. At 3:48 p.m., the suspect was taken into custody without incident.

David Basil Mercer was booked into the Elko County Jail on charges of basic speed, 41+ mph over the posted speed limit; reckless driving; evade, elude or fail to stop; resisting a public officer; using or being under the influence of a controlled substance; possession of a controlled substance; and DUI.

Nevada Highway Patrol thanked its partner agencies, including the Eureka County Sheriff’s Office, Carlin Police Department, Elko Police Department, Elko County Sheriff’s Office, and the Parole and Probation Division of the Nevada State Police.

More than 270,000 Nevadans have participated in the primary elections

More than 270,000 Nevadans have participated in the primary elections


More than a quarter-million Nevadans had participated in the state’s primary elections as of Friday afternoon, a few hours before the two weeks of early voting concluded.

The 270,008 people who had voted in person or returned a mail ballot amounted to a roughly 11 percent participation rate out of the more than 2.4 million active and inactive registered voters in Nevada as of Monday.

At least 181,139 ballots had been returned statewide, and 86,869 people had voted in person since May 23.

Secretary of State Francisco Aguilar, Nevada’s chief election official, said Friday that the early voting process had proceeded without hiccups, crediting county clerks and election workers.

“Everything has gone very smoothly,” he told the Las Vegas Review-Journal. “Clerks have been preparing for this moment since the day after the 2024 election.”

Aguilar said he otherwise wished turnout was higher.

Nevadans who want to vote in person still have one final chance: on Election Day Tuesday.

Those who wish to mail back their ballots can do so through that day, although Aguilar recommends that they take them to drop boxes or polling locations instead, to ensure that they are counted.

For now, Nevada law allows returned mail ballots to be counted several days after Election Day. Ballots postmarked by Election Day are accepted for up to four days, while mail returned without a legible postmark is accepted for up to three days.

A Supreme Court ruling — which is expected to come down after the primaries — could lead to the reversal of laws in Nevada and about a dozen other states that allow the counting of mail ballots received days after Election Day.

If the higher court rules against Mississippi, whose law was challenged by the Republican National Committee and the Mississippi Libertarian Party, the change could go into effect as early as November’s midterm elections.

“As opposed to any of the president’s executive orders, we can’t challenge a ruling by the U.S. Supreme Court or file a lawsuit against it,” Aguilar said in late May. “We have to accept it.”

About 57,000 Clark County residents had voted early and in person as of Friday afternoon, state data showed. Almost 108,000 had returned their mail ballots.

Aguilar said that he’s been encouraging clerks to push voters whose mail ballots require signature verification, a process known as curing, to get it done as soon as possible.

Clark County had flagged at least 1,621 ballots that needed curing as of Friday afternoon. At least 543 of those voters had since verified their signatures.

There is a plethora of nonpartisan and partisan local, state and federal races on the ballot. Some can be won outright this month. For others, like congressional and the governor’s races, voters will have a chance to dwindle the field that will then face off in November.

Nevada offers same-day, in-person registration for inactive voters, which requires a state identification card. Registered voters can track their ballots at myballot.nv.gov and update their contact information at vote.nv.gov.
