Prepare Kansas: Keep Food Safe during a Disaster

Nora Rhoades- Family and Youth Development Agent

Facebook will play a key role in Prepare Kansas 2016, K-State Research and Extension’s effort to prepare Kansans for emergencies.

Ice storms, tornadoes, and flooding, oh my! Kansas has them all and more. Do you really know how long food will stay safe in the refrigerator if your power is out? Or what foods and supplies you should have on hand in case of emergencies?

Starting September 1, Prepare Kansas 2016 will provide tips on keeping food safe in emergency situations. This year’s program will be conducted through the K-State Research and Extension Facebook page. No registration is required, so Kansans and anyone interested in planning ahead for emergencies can follow on Facebook at any time during September, pick up handy information and interact with K-State extension specialists and agents. 

Throughout 2015, a total of 126 tornadoes alone occurred across the state, which made it the fourth highest year for tornadoes since 1950, according to the Kansas Department of Emergency Management.

“Kansas has its share of disasters, whether it’s a homeowner’s basement flooding or a fire affecting a whole block in a community. We’re committed to working with people across the state to help them be prepared for anything that comes their way,” said Kansas State University associate professor Elizabeth Kiss. “We can’t always keep disasters from happening, but we know that being as prepared as possible, whether it’s making an emergency kit or having copies of your financial and personal information in a separate, safe place, aids in the recovery from disasters.”

K-State Research and Extension has a Prepare Kansas blog, which provides tips and resources on a range of emergency preparedness topics, including this September’s focus on food safety.

“It is very important to keep food safety in mind before, during and after emergencies such as power outages and floods, to help to reduce the likelihood of people getting sick from eating contaminated food. That would make a challenging situation even worse,” said Londa Nwadike, consumer food safety specialist with K-State Research and Extension. “Some of the food safety practices that are important in emergency situations are good practices to help prevent people from getting sick at any time.” 

More information on Prepare Kansas will be available in September at and any time at

Remember to control your VOLUNTEER wheat!

Sandra Wick - Crop Production Agent

    Producers are gearing up to plant their 2017 wheat crop around north central Kansas! Producers really don’t like the mention of volunteer wheat, but you can always count on it rearing its ugly head. Volunteer wheat is a fact of life in wheat production and no combine is perfect, so there is usually plenty of grain left on the ground in the field to produce volunteer.
Volunteer wheat can serve as a host for insects such as the wheat curl mite, Hessian fly, greenbug and the bird cherry-oat aphid along with diseases such as wheat streak mosaic and barley yellow dwarf. Wheat Streak mosaic, spread by the insect…the wheat curl mite, is the most important threat from volunteer wheat.
    The wheat can be infected with the wheat streak virus in the fall or in the spring with fall infection most impacting the yield. Adult and immature wheat curl mites are tiny, white, cigar-shaped organisms with four legs near the head. They are nearly invisible to the naked eye and fit between the veins of the wheat leaves. Eggs are placed in rows along leaf veins. The mites reproduce most rapidly at 75° to 85°F. Reproduction stops at temperatures near freezing, but the mites can survive for several months at near freezing temperatures and for several days at 0°F. Under good conditions, a generation can be completed in 10 days. Most mites are found on the terminal leaves and move to each new leaf as it emerges. Heavy mite populations can cause the leaf margins to roll or curl inward, hence the name. As the wheat plant dries down, the wheat curl mites congregate on the flag leaves and even the glumes of the head where they are picked up by wind currents and carried to their over-summering grass hosts including volunteer wheat, corn and a few other grasses. As summer hosts start to dry down the reverse process occurs and mites are carried by winds to newly emerged winter wheat. The most severe wheat streak mosaic is found where volunteer wheat provides a "green bridge" through the summer between successive wheat crops. Hail during the heading period can also lead to high over-summering populations by knocking heads containing wheat curl mites to the ground and starting early volunteer. This early volunteer can then be immediately infested with wheat curl mites. Look for yellow streaking or mosaic patterns on young leaves. Infected plants are stunted and tiller poorly and tillers may sometimes be prostrate on the ground.
    On average, Kansas producers lose 10 million bushels per year to this disease. Control of volunteer wheat is the best defense against the wheat streak mosaic virus.
    If the volunteer is still alive, or worse yet, dying when new wheat is emerging, pests and diseases will likely move from the volunteer wheat directly into the new wheat. Some worst cases of wheat streak mosaic, in past years, were in fields where volunteer was sprayed soon after the wheat crop was planted. As the volunteer slowly died from the herbicide the wheat curl mites moved into the emerging wheat and spread the wheat streak virus to the plants.
    Volunteer wheat can be destroyed by either conventional tillage or by use of chemicals or a combination of both. Destruction of volunteer wheat at least 2 weeks prior to planting winter wheat in the fall is the most effective management practice for controlling the wheat curl mite and the disease that it vectors. Avoiding early planting can also reduce wheat curl mite numbers and the length of time that they have to transmit the wheat streak virus. Varietal selection can also be an important way to reduce the impact of wheat streak. Producers in areas where wheat streak is common should avoid varieties that are highly susceptible to the wheat streak mosaic virus. To date, control of wheat curl mites with foliar miticides has not been shown to be an effective practice. Since the mite is carried by the wind from plant to plant and from field to field, the control of ALL volunteer is essential. The mite can be carried for several miles so the cost of NOT controlling volunteer may hurt you and also your neighbor.
    If you are noticing volunteer wheat close to where you will be planting winter wheat you may want to select a variety that has some resistance to wheat streak mosaic or plant later as indicated by your fly free date which ranges from September 29 in Jewell and Smith Counties to October 4 in Lincoln with Osborne and Mitchell counties in between those dates. Very few of our common wheat varieties have any resistance to wheat streak mosaic, but a few varieties have some resistance including KSU 1863, Oakley CL, SY Wolf, and T-158.
  A couple of excellent publications are available for producers through K-State Research and Extension including the 2016 Wheat Variety Disease and Insect Ratings along with the 2016 Chemical Weed Control for Field Crops, Pastures, Rangeland and Non-cropland. The Disease ratings publication provides evaluation of each of the wheat varieties for disease and insect resistance while the chemical publication outlines weed control chemicals for each of the major crops in Kansas. Remember volunteer wheat is the source of severe problems and may actually cost much more if NOT controlled. Stop by or call any office of the Post Rock Extension District for the publications I mentioned, or additional information on controlling volunteer wheat.
    The Post Rock Extension District will be hosting 2 Pre-Plant wheat meetings on Wednesday, August 24 in Osborne at the United Christian Church starting at 9:30 a.m. until NOON and in Mankato at the Community Center starting at 3:00 p.m. until 5:30 p.m. Both meetings will include the same information just at different locations and times. Meals will also be served at both locations with local sponsors. RSVP is requested by Friday, August 19. A minimum of 10 registered producers at each location is needed to hold the meetings. For more details, visit our Post Rock Extension District Website or contact any Post Rock Extension District office in Beloit, Lincoln, Mankato, Osborne or Smith Center.
