Bagworms are a yearly pest in our area and can cause considerable damage. Most homeowners typically don’t get too concerned about bagworm control until they see large bags present on plants. By then it is too late and the damage is already done! Now is the time to get your treatment game plan ready.

Bagworms overwinter as eggs deposited in the female bags. From mid-May through mid-June, larvae hatch from the eggs and exit from the bottom opening of the old bag. Larvae begin constructing their miniature silk-lined bags immediately. Only after the bags have been completed do the larvae begin actual feeding activities. And as the larvae grow, so do their bags. By mid-to late August when feeding activities are complete, larvae firmly anchor their bags to the twigs and branches on which they were feeding.

Bagworms are most commonly found on eastern red cedar and junipers. However, bagworms can attack arborvitae, spruce and pine. Broadleaf trees, shrubs and ornamentals can also serve as a host to bagworms. After bagworms have defoliated a host plant, they are capable of migrating in search of additional food sources. They may attack the same species from which they came or a completely different species.

The damage caused by bagworm feeding can be minimal to severe. As larvae enter their later development stages, they require greater amounts of food. Sometimes in what seems to be just overnight, bagworms can completely defoliate a tree. Several successive years of heavy foliar feeding can result in the death a tree, especially with conifers.

There are two ways to control bagworms – cultural and chemical. Cultural practice is used by those who do not want to utilize insecticidal sprays to control bagworms. Instead, bagworms are eliminated by handpicking individual bags from plants. This is best done in the winter months when bags stand out against a trees background color. Keep in mind that a single missed bag could result in a thousand new bagworm larvae. Of course handpicking becomes impractical when a host is literally covered with bags or it is too tall to make handpicking possible.

Chemical control is most effective when larvae are in their early developmental stages. Generally, bagworm larvae will begin emerging from the overwintering bag by mid-to late May. Hatching does not happen overnight. Instead, hatching can continue for 4 to 5 weeks. Controls applied in late summer are often a waste of time and expense because the larvae are large, tough and may have stopped feeding. Now is the time to find the correct insecticide and get the sprayers out and ready for the job ahead.

KOMA Beef Conference will be coming back to Kansas –

Girard, KS – The KOMA (Kansas, Oklahoma, Missouri, and Arkansas) Beef Cattle Conference will be coming back to Kansas on January 24, 2019 after a long hiatus. The 4-State area’s premier beef cattle conference is designed to help cow-calf producers make better managerial decisions. Next year’s hosts include The Southeast Area Research and Extension Center of Kansas State University, Southwind Extension District, Wildcat Extension District, and Cherokee County Extension.

The conference will take place at Greenbush Education Service Center in Greenbush, KS (947 W. 47 Hwy. Girard, KS), beginning at 10:30 am with registration, and the chance for producers to visit with sponsoring agricultural businesses. Educational sessions will begin at 11:00 am and end at 3:45 pm, with a free catered lunch included.

The focus of this meeting will “From Grass to Cash”. Precentors from Kansas, Oklahoma, and Missouri will address forage management, cow-calf management, cow herd diseases, and economics of production.

The day will begin with Dr. Glynn Tonsor of Kansas State University. Tonsor is a Professor in the Department of Agricultural Economics. Tonsor’s current research and extension efforts focus on cattle and swine industries. Tonsor’s interests span areas of production supply issues to end-user consumer demand issues in regards to the meat supply chain. The title of Tonsor’s presentation will be “Feeder Cattle Marketing Outlook”. He will address marketing strategies for 500 to 800 pound calves.

Dr. David Lalman of Oklahoma State University will be the next speaker with the presentation titled, “Matching my cows to my environment”. Lalman is a professor and Extension Beef Cattle Specialist at Oklahoma State University. Lalman holds the Harrington Endowed Chair with split extension and research appointment. He works primarily in the beef cattle industry focused on cow/calf and stocker cattle production. His extension and applied research program includes beef cattle nutrition and management with emphasis on beef cattle grazing and genetic by environment interactions in beef production systems. His program goals are to provide producers with information and decision tools to facilitate production system profitability, improve cow herd efficiency and to improve product quality. Lalman will discuss the historical changes in cattle phenotype we have been observing and discuss the benefits and possible pit-falls of this changing herd population.

Dr. Gregg Hanzlicek, DVM of the Kansas State University Veterinary School will provide the health component of the program. Dr. Hanzlicek is the director of Production Animal Field Investigations within the Veterinary College. Hanzlicek works with pathologists and microbiologists within the laboratory to diagnosis bovine health events. Hanzlicek’s research activities include disease surveillance and monitoring systems for beef and dairy health programs and disease surveys. For the KOMA Beef Conference, he will specifically be addressing blood-borne diseases of the cattle herd such as anaplasmosis.

Dr. Jordan Thomas from The University of Missouri will discuss, “Optimizing reproductive performance”. Jordan Thomas is an Assistant Extension Professor and State Beef Reproduction Specialist in the Division of Animal Sciences at the University of Missouri. Dr. Thomas is a Missouri native and University of Missouri alumnus, having earned his Ph.D. in Animal Sciences with an emphasis in Reproductive Physiology in 2017. In addition to extension and education programming associated with the National Center for Applied Reproduction and Genomics, Dr. Thomas maintains an active applied research program in reproductive management of beef cattle. The primary research focus of the Thomas lab is control of the bovine estrous cycle, specifically to facilitate use of reproductive technologies such as timed artificial insemination and embryo transfer. 

The final speaker will be economist Wesley Tucker who is a field specialist in agricultural business from the University of Missouri. Tucker’s work currently focuses on farm transactions and productivity and profitability of beef cattle. The title of Tucker’s presentation is “Keys to profitability for beef producers”. He will address forage production with the goal of economically maximizing grazing.

Sponsors of the event include Ag Choice of Hepler, Frontier Farm Credit, Girard Coop, GNBank, MultiMin, and Zoetis. These sponsors will have trade show style booths. Bring your questions and thank them for their sponsorship and support of beef cattle production.
