Sugarcane Rootstock Weevil(September 25, 2002) -- This weevil may be an occasional contaminant of stored grain, particularly sorghum. Though it is not known to feed on harvested grain, it can (because of its similar size) be confused with grain damaging species. It can be separated from the rice weevil or granary weevil by comparing characteristics illustrated in this document. For more information see: Misc. Extension Document>Sugarcane Rootstock Weevil
Soybean aphids found in four Kansas counties Aug. 20, 2002
TOPEKA -- The Kansas Department of Agriculture announced today that soybean aphids were detected in soybean fields in Geary, Douglas, Franklin and Miami counties last week and producers are encouraged to scout their fields for this new pest.
The pest was discovered during routine plant pest survey and detection activities, which are part of an ongoing effort to monitor for the presence and distribution of plant pests in the state.
"The aphids we found appear to be distributed in a line from just south of Kansas City to Junction City, so we suspect they were blown in from western Missouri" said Tom Sim, manager of the
department's plant protection and weed control program. "We haven't encountered anything to suggest a severe infestation, but we're watching this very closely."

Stink Bugs on Corn
Unusual damage reported from a no-tilled corn field in Kingman county (report and photographs from Dale Fjell, KSU Agronomy, by way of Randy Higgins). Plants were found with buggy whipping, holes with yellow boarders in emerged leaves and "suckering" (the production of tillers from the base of damaged plants). Closer inspection revealed a few stink bugs in the area. Weird Weevil Attack Underway in Alfalfa MANHATTAN, Kan. – An alfalfa weevil problem not seen in 30 years has shown up in the Emporia, Kan., area – worrying Kansas State University entomologists about its potential statewide. The weevil’s larvae are the state’s usual culprit. Farmers routinely scout for them and apply needed controls. This year, however, the controls didn’t always get the job done. Masses of adults have emerged near Emporia and begun feeding just as the year’s alfalfa crop is reaching first-cutting stage.
Army Cutworm Moths are currently abundant in western Kansas. April 30, 2002 PES -- At this time of year they are just a nuisance as migrate through the state to spend the summer in Colorado, but they can create problems as they invade houses, out-buildings and cars. For more information see: Colorado's "Miller" Moths http://www.colostate.edu/Depts/CoopExt/LARIMER/millers.htm
Cowpea aphids and alfalfa weevil larvae are being reported from alfalfa fields. For more information refer to Alfalfa Insect Management:
Stories from 2001 Tracer released for controlling beet armyworms on alfalfa. May 25, 2001-- The Kansas Department of Agriculture has released a Section 18 Crisis Exemption permitting the use of Tracer (EPA Reg. No. 62719-267) for control of beet armyworm infesting alfalfa.
Fire Ants In Kansas May 4, 2001: Its true, a red imported fire ant infestation has been confirmed in Kansas. They were recently found in Lawrence. Based on computer-generated models, some scientists had predicted that our climate in Kansas was too cold for fire ants to survive, but Tom Sim, Program Director of the Plant Protection and Weed Control Division, of Kansas State Dept. of Agriculture says, "The ants we found were alive and doing well. It appears they have been here two or three years, getting established and expanding their colonies in one of the newer suburban neighborhoods in Lawrence." As of this week, Tom said they have located seven colonies, two in the front yard on private property; then around to the rear of this residence, they have so far found five others, all situated along a utility easement alongside an alley. The source of the Lawrence infestation is unknown. It could be the result of planting infested nursery stock or the ants could have been carried in the soil of earth moving equipment brought in from an Infested area. The State Department staff is presently trying to locate additional colonies and destroy all sources of infestation. Since this infestation may be firmly established, eradication efforts could prove to be difficult. Alfalfa Weevil Adults and Hornworms on Non-Alfalfa Crops
(also true armyworms and alfalfa caterpillars) May 29, 2001 Misc. Extension Document>Alfalfa Weevil and Hornworms
In some cases, alfalfa weevil adult populations from these non-treated Kansas alfalfa fields are so heavy they are moving out of the alfalfa fields and into nearby soybeans, causing extensive damage and hornworms, larvae of the white-lined sphinx moth, are heavy in several no-till fields that had mustard and possibly other weeds present prior to planting. Several companies releasing 2ee labels for these problems. BT Corn Growers Have Responsibility to Provide ’Refuges’ Misc. Extension Document>Bt Corn and Refuges MANHATTAN, Kan. – Bt corn has been the subject of plenty of headlines lately – some linked to fact and some not – but one thing’s for sure, the proper use of Bt corn is an effective way to control destructive corn borers without the field-wide use of traditional, broad-spectrum insecticides, a Kansas State University entomologist said. To keep Bt corn effective against corn borers, however, growers have a responsibility to abide by certain management guidelines provided by seed companies when they buy the seed, said Randy Higgins, state leader in entomology with K-State Research and Extension. The guidelines were mandated by the U.S. Environmental Protection Agency [EPA] and are described in some detail within grower agreements that every purchaser of Bt corn must sign. Soybean Aphid: A New Pest for North America The soybean aphid (Aphis glycines), originally a native of China and Japan, was first identified in the United States during the summer and fall of 2000. Infestations were confirmed in several Midwestern states from Ohio to West Virginia and Kentucky, west into Missouri and Iowa. Late last summer, the heaviest infestations were located in Michigan, Wisconsin, Minnesota, and Illinois. At the moment, we do not know of confirmed infestations within the state of Kansas, with the nearest verified sightings occurring about midway through Iowa and Missouri. Ethyl Parathion; EPA Announces Receipt of Request For Registration Cancellations and Amendments
Federal Register: May 2, 2001 (Volume 66, Number 85)
EPA is issuing a notice of receipt of request to immediately cancel the use on corn grown for seed by amending their ethyl parathion end-use product registrations; and to cancel all of their ethyl parathion end-use products effective as of December 31, 2002. EPA will decide whether to approve the requests after consideration of public comment. Comments on the requested cancellation of product and use registrations must be submitted by June 1, 2001.
EPA anticipates that any cancellation order issued in response to the registrants' request for voluntary cancellation of end-use product registrations would:
(1) Prohibit, as of December 31, 2002, registrants from distributing or selling existing stocks of the end-use products;
(2) Prohibit, as of August 31, 2003, all sale and distribution of existing stocks of the end-use products; and
(3) Prohibit, as of October 31, 2003, all use of existing stocks of the end-use products. Is there an Armyworm Threat? Misc. Extension Document>Armyworm Threat
May 22, 2001:
Is there an Armyworm Threat? There is a lot of news coverage about this now in southern Missouri, Arkansas and some parts of Oklahoma in pastures, lawns and wheat. This pest is the true armyworm, not the same species as the fall armyworm we experienced in lawns and pastures last summer. We don't have a confirmed problem in Kansas yet, but we may see some infestations develop. Problems with other worms such as black cutworms, variegated cutworms and beet armyworms are being reported in Kansas Stories from 2000 EPA ANNOUNCES ELIMINATION OF ALL INDOOR USES OF WIDELY-USED PESTICIDE DIAZINON; BEGINS PHASE-OUT OF LAWN AND GARDEN USES
Today (TUESDAY, DEC. 5, 2000), EPA announced an agreement to phase-out diazinon, one of the most widely used pesticides in the United States, for indoor uses, beginning in March 2001, and for all lawn, garden and turf uses by December 2003.
Chlorpyrifos Revised Risk Assessment and Agreement with Registrants June 2000: EPA has released its revised risk assessment and announced an agreement with registrants to eliminate and phase out certain uses of the organophosphate pesticide chlorpyrifos. Also known as Dursban, Lorsban, and other trade names, chlorpyrifos is one of the most widely-used insecticides in the U.S., both in agriculture and in and around the home.
Soybean Stem Borers
We are continuing to monitor the distribution of this pest in soybeans fields through out the state as part of a Grant from the Kansas Soybean Commission. The link given above will take you to a page with the latest map on the know distribution of this pest on soybeans in Kansas.
Starlink Recall Aventis, the maker of StarLink (sold through Garst Seeds), has agreed to a government request to formally withdraw StarLink from the US market. The company had previously issued a "stop sale" order; but now it's official, StarLink cannot be planted for any agricultural purpose. In addition: Working with the USDA, Aventis will purchase from growers all StarLink corn which is not intended for feed use on the farm. These growers, as well as those who do use it for animal feed on their farm, will be paid a $.25 per bushel premium above the posted price for corn. This premium applies to StarLink corn and corn grown within a 660-foot buffer.
Southwestern Corn Borer Threat to North Central Kansas
The bad news is that we have it-a new pest here in north central KS (during the year 2000). If given the opportunity, the southwestern corn borer (SWCB) can be a very destructive pest. How did this become a problem? Time Extension for B.t. Corn and B.t. Cotton Plantings -- Federal Register: August 9, 2000 (Volume 65, Number 154) EPA announces plans to extend the registrations of Bt corn and Bt cotton through next year's growing season. In turn, this decision permits more time for on-going data review and scientific assessment before the Agency reaches a more permanent decision on the future of corn borer-active, Bt corn hybrids.
