What is Extension?

Just a little bit about Nebraska Extension.

Views from VanDeWalle

Often times when I tell people I work at the “Extension Office” they have no idea what it is we do. It is so hard to describe without giving a plethora of information. One of our signature programs people often most often associate with is the 4-H program. While this is a large and very successful component of Extension, it is only one of many programs.ExtensionDifferencepic

Everyday, whether you know it or not, you have most likely been indirectly impacted by Extension programming. Extension essentially takes science and research-based information from the University Of Nebraska – Lincoln and delivers it into the hands of the public. We make UNL easily accessible to the public. For example, we provide services and resources to the agricultural community, but also sectors as diverse as nutrition, health care and technology. From border to border, Nebraska Extension is making an incredible impact on the success…

Proposed Pesticide Certification Rule Changes

Some proposed changes to Pesticide Certification.

Views from VanDeWalle

As many producers know, in order to obtain a pesticide applicators license and purchase Restricted Use Pesticides (RUPs), every three years you complete a private pesticide certification program or self-study program. The Environmental Protection Agency (EPA) is proposing stricter standards for people to use RUPs and have determined that use of these RUPs would be safer with increased supervision and oversight, and to require all people who apply RUPs to be at least 18 years old (Nebraska currently requires applicators to be 16 years old). These proposed changes apply to the FIFRA/Certification of Pesticide Applicators Rule.pested

Information below has been summarized from the Nebraska Extension Pesticide Safety Education Program which I’ve decided to share with you this week, to make you aware and allow you to provide your feedback as the public comment period for the proposed changes to the certification rule will run through November 23, 2015.

Bagworms in Evergreens

Evergreen Bagworms can be a big issue in juniper and spruce. Read more from Jenny’s blog.

JenREESources's Extension Blog

I’ve been receiving questions regarding when to spray for bagworms. Bagworms overwinter as eggs in these up to 2″ bags which are formed throughout the summer with silk and evergreen needles by larvae. Larvae feed until late August or early September. Males then emerge and mate with females through the bag opening in September. 500-1000 eggs are deposited by female moths within their own bags.  After depositing eggs, the females drop to the soil and die.  Bagworms overwinter as eggs within bags fastened to twigs such as these shown in this photo.

Bagworms Eggs hatch in mid-May to early June. Some caterpillar larvae remain on the same trees containing the bags from which they hatched.  Others are blown by the wind to area trees allowing for new infestations to occur.  This photo shows new bags (1/8-1/4″) being formed on trees as they create these bags around themselves.  Look closely for these tiny…
