Herbicide Field Day on Goosegrass Control


To: Golf Course & Landscape Industries
From: Norman M. Nagata, Extension Agent

A test was conducted at Waiehu Municipal Golf Course to evaluate the efficacy of several herbicide combinations with Roundup, Revolver, MSMA, and Sencor to control herbicide resistant goosegrass using 2 spray applications at 2 weeks apart. You are invited to a field day to observe the results of this test.

Herbicide Field Day on Goosegrass Control

Date: April 7, 2011 (Thursday)
Time: 11:30 am to 12:30 pm
Place: Meet at Waiehu Golf Course “Service Entrance” (6th tee) next to Waiehu Beach Park & Baseball Field located at the end of “Lower Waiehu Beach Road” (MAP) at 11:15 am am. We will then car-pool to the test site at the 17th tee.

To Bee or Not to Bee

By Glenn I. Teves, County Extension Agent, UH CTAHR Cooperative Extension Service

The relationship between humans and honeybees is ancient, as demonstrated by cave paintings in Spain, South Africa, and Nepal, depicting honey hunters collecting honey from wild hives. The honeybee was introduced to Hawaii in 1857, but the accidental introduction of the Varroa mite in 2007 puts this relationship in jeopardy and is one example of Hawaii’s vulnerability to invasive species.

The Varroa mite (Varroa destructor) is one of the most serious pests of honeybees and is associated with the spread of viruses and the decline of honey bee colonies on the mainland. And it’s only a matter of time before it destroys all feral honeybee colonies in Hawaii. On the island of Oahu alone, over 90 percent of the wild colonies have been wiped out and it has now moved to the Big Island, starting in Hilo. Visual checks of feral honeybees in Ho`olehua and Mo`omomi have not found the Varroa mite to date.

The mites attack both adult bees, and also larvae in the hive. Although honeybees in Hawaii are crosses between German, Italian, and Carnolian bees, the honeybees on Molokai appear to be a special disease resistant strain, first brought in around 1898. They show resistance to a disease called Foul Brood, which wiped out honeybees on most of the islands starting in 1908.

Genetically Engineered Crops Benefit Many Farmers,
But The Technology Needs Proper Management to Remain Effective

WASHINGTON — Many U.S. farmers who grow genetically engineered (GE) crops are realizing substantial economic and environmental benefits — such as lower production costs, fewer pest problems, reduced use of pesticides, and better yields — compared with conventional crops, says a new report from the National Research Council. However, GE crops resistant to the herbicide glyphosate — a main component in Roundup and other commercial weed killers — could develop more weed problems as weeds evolve their own resistance to glyphosate. GE crops could lose their effectiveness unless farmers also use other proven weed and insect management practices.

The report provides the first comprehensive assessment of how GE crops are affecting all U.S. farmers, including those who grow conventional or organic crops. The new report follows several previous Research Council reports that examined the potential human health and environmental effects of GE crops.
