Be aware of summer crop pests

With some crops being replanted in areas where there was hail damage, newly seeded crops are just coming up and susceptible to insect damage. As we move through the summer, older soybeans are also susceptible to insect pests. It is just important to scout fields periodically to monitor new infestations of pests. Also, CropWatch, https://cropwatch.unl.edu/ is a good resource for information on current crop conditions in Nebraska. In southeast Nebraska, we have been subject to isolated infestations of insect pests over the years. More recently the thistle caterpillar, which is the larval stage of the Painted Lady Butterfly. Many people were concerned about the millions of butterflies that invaded us, but it is larval stage which come from the eggs that the butterflies lay that can cause defoliation of soybeans. There were some fields that required treatment in southeast Nebraska. Another pest that showed up was the garden webworm. These types of insects would cause more issues with newly replanted soybeans due to much less foliage. Generally soybeans in the vegetative stage require treatment when defoliation reaches 30%. Here is a link to a graphic reference showing different levels of defoliating; https://cropwatch.unl.edu/soybean-defoliation-7-24-09 .

Inflammation and the Immune System

Many of my patients will say “Doctor, I am so inflamed”. The use of the word inflammation is commonplace as we search the market for anti-inflammatory diets or self-help books on inflammation. The inflammatory response created by the immune system contributes to healing, but when left unchecked can contribute to chronic disease, allergy, and non-specific symptoms such as achy joints, fatigue, and malaise. The immune system has two main parts. The first of these is the innate immune system which is the body’s first line of defense. The innate immune system acts as a barrier that prevents harmful materials from entering the body and responds quickly when needed. The second part is the adaptive immune system. This system is more specialized and takes over if the innate immune system is unsuccessful. The adaptive immune system responds slower than the innate immune system but more accurately.

Sportsmanship principles all young athletes should know

Competitive sports have a lot to offer young people. In addition to exposing children to the thrill of competition, competitive sports can set a foundation for a lifetime of healthy living. One study published in the American Journal of Preventive Medicine in 2014 found that afterschool physical activity programs were the most effective strategy to reduce childhood obesity among children between the ages of six and 12.
