You will have an opportunity to tour and learn more about Barnacopia, a peg-built structure, which opened in November 2011. The building features three levels of unique, antique tractors, cars & much more. Here are some of the things you will see when you visit the museum at Barnacopia.
The '53 Ford on the 2nd level is the first car Gary drove at 12 years old – pre-license era!
Enjoy a view of Mason St. in Polo, IL from the 1950's.
Play pool on the John Deere pool table in the game room on the 3rd floor.
Hang out in the 50's & 60's diner with operating jukebox & ice cream parlor.
The headboard on the 3rd floor is made from the hay loft door from Judy's dad's (Max Plum) farm.

We Came From, and What We Think We’re Doing
URBANA, Ill. - Signs and symptoms of a few soybean diseases have begun to show up in some areas of the state over the last few weeks, and two of these diseases, sudden death syndrome (SDS) and Sclerotinia stem rot (white mold), are likely to cause economic losses in some growers’ fields this year, said a University of Illinois plant pathologist.
Carl Bradley explained that symptoms of SDS that currently are being observed include interveinal chlorosis and necrosis of the leaves (veins remain green while the tissues between the veins turn yellow and then brown). “These symptoms look exactly like the foliar symptoms caused by a different disease, brown stem rot. Brown stem rot, however, causes internal browning of the pith in soybean stems while SDS does not affect soybean stems,” he said.
On SDS-affected plants, the leaves will fall off eventually, while the petioles will remain attached to the stems and branches. In some cases, Bradley said, a bluish-white mass of spores of the SDS fungus (Fusarium virguliforme) may be observed on the roots.
“Although the foliar symptoms of SDS are now being observed, infection by the SDS fungus occurred during the seedling stage, not long after planting. The symptoms that are now being observed are the effect of toxins that the SDS pathogen produces that are phytotoxic,” he said.
Cool and wet weather after planting along with recent rainfall received in parts of the state have been favorable for infection and disease development and are the reasons that SDS incidence is high in some areas this year, Bradley explained.
“The primary method of managing SDS is to choose the most resistant soybean varieties available. Some evidence has shown that high soybean cyst nematode (SCN) egg populations may also increase the likelihood of severe SDS; therefore, managing SCN populations through resistant varieties and crop rotation may also reduce the risk of SDS,” he said.
White mold has also been observed in fields located in the northern half of Illinois this year. “The appearance of this disease also is weather-related. Areas in the northern half of the state that were cooler and wetter than normal after soybean plants began to flower are the areas that are affected the most severely,” Bradley said.
“Unfortunately, once white mold signs and symptoms are detected in the field, fungicide applications generally will be futile as the damage has already been done,” he added.
Bradley said that growers with severe levels of white mold may encounter some discounts at the elevator this year for high levels of foreign matter. “Some sclerotia (dark survival structures produced by the white mold fungus – Sclerotinia sclerotiorum) that are formed on plants may be similar in size to the seed, and will make their way to the hopper and eventually the elevator, where discounts may be received,” he explained.
URBANA, Ill. – Though some growers may be wondering if they took full advantage of this year’s high-yielding conditions, a University of Illinois crop scientist said data does not necessarily show that increasing plant population would have made for bigger yields this year.
“Did we all miss the boat by planting ‘only’ 35,000 or so seeds per acre this year? Fortunately, we have data to answer this question,” said Emerson Nafziger.
“Since 2011, we have been running trials at a dozen sites around Illinois in which we plant six to eight hybrids at a range of populations, including planting rates of 34,000 and 42,000. Plant counts show that actual stands are very close to planted populations,” he said.
Over 277 comparisons from the past three years show that the difference in yield between these two populations was only about a tenth of a bushel, and Nafziger said there was no indication that the response got larger as yield level increased.
“In fact, the line drawn through the points shows slightly lower yield differences as yield level increased,” he said.
At yield levels less than 150 bushels per acre, Nafziger said that 42,000 plants yielded 9 bushels more than 34,000 plants, with a range of -62 to +48 bushels. At yields above 250 bushels per acre, 42,000 plants yielded a half bushel less than 34,000 plants, and the range was -24 to +24 bushels.
“This reinforces what many of us know – that low-yielding conditions tend to make yield less consistent, with more differences due to factors like hybrid stress tolerance water-holding capacity within fields,” he said.
Nafziger said that these data give no support to the idea that a corn crop planted at populations in the mid-30,000 range is incapable of taking full advantage of high-yielding conditions. He added that the data also confirm that risks of having populations too high for the conditions increases when there are not conditions for high yields.
“Because we don’t know what conditions will be at the beginning of the season – the 2012 season started off great and would have been a good season to raise populations at planting, but with very negative outcomes as conditions stayed very dry – it makes no sense to push populations above 40,000 in hopes that we’ll get the weather to make this pay off. In fact, the response of yield to population tends to be fairly flat over the range of the lower to the upper 30,000s, regardless of yield level or conditions,” he said.
Nafziger added that there are occasional yield increases ranging from the lower to upper 30,000s. “The 2014 growing season has been so outstanding that this could be one of those times. But such increases tend to be modest, and they don’t always pay for the additional seed,” he said. “Today, it takes nearly a bushel of added yield to pay for 1,000 more seeds. While responses of this size are possible, they are not common at population levels that most producers already use.”
