Researchers at the USDA have identified a leading culprit for the massive honey bee die off.: Varroa mites harbor virulent virus that weaken and eventually kill honey bees. Varroa mites have become resistant to amitraz, the only remaining widely used miticide for hives. Amitraz was widely used, but no longer is considered effective at controlling Varroa mites in honey bee hives. The Varroa mite is an external parasitic mite that attacks and feeds on honey bees. The Varroa mite is one of the most damaging honey bee pests in the world. A significant mite infestation leads to the death of a honey bee colony or hive, starting in late autumn through early spring. Often hives become weak over the winter and the honey bee population in a hive is decimated by spring. Without management for Varroa mite, honey bee colonies typically collapse within 2 to 3 years in the USA. The Varroa mite can reproduce only in a honey bee colony. It attaches to the body of the bee and weakens the bee. The Varroa...

  Fast seed germination is critical to achieving high crop yields.  Cold wet weather often causes early crop stress that can be difficult for the plant to overcome and may cause long-term yield loss. Corn seed that germinates 3 days later than its neighbors is like a weed.  Fast seed emergence has many advantages.     First, the seed generally has enough energy to get the roots established and a leaf growing to capture the sun’s energy.  When seed roots emerge quickly though, there is less time for seed damage by insects, especially seed corn maggots, wireworms, and root worm larva.  Fast growing plants can outrun most slug damage or flea beetle which feast on sickly plants that are struggling to grow quickly.  Corn seeds provide nourishment for 7-14 days or until V3 while soybean its 7-10 days. New growing roots supplement seed nutrient reserves to improve plant growth, especially from micro-nutrients needed to speed up plant growth.  When s...

Carbon credits are still around and farmers should pay attention because it can be a profitable revenue stream. A carbon credit is a tradeable certificate for 1 metric ton of carbon dioxide removed from the atmosphere or recycled through sustainable farming practices. Farmers can sell these credits to companies as carbon offsets in voluntary markets. Practices like no-till farming, cover crops, and even using some biologicals increase carbon in the soil. For the farmer, getting paid to increase carbon or soil organic matter (SOM is 54% carbon) is a win-win proposition. Higher SOM increases yields and retains fertilizer nutrients and water for better crops. For farmers, up to 60% higher profit is possible by cutting back on fertilizer and still maintaining or even increasing crop quality and crop yields. Environmental benefits are also better. Less fertilizer used means less nutrient runoff and higher water quality. Improving SOM leads to less soil and wind erosion. For the consumer, t...

Pesticides (Herbicides, Insecticides, Miticides, Fungicides etc.) may affect soil microbes in many ways, often leading to reduced diversity and even lower populations of various soil microbes. Soil microbes are bacteria, fungi, archaea, protists, and viruses and account for an estimated 3%–4% of the total biomass on earth. Pesticides often degrade soil health and can lead to lower agricultural productivity or lower crop yields. Some pesticides change the soil structure so that soils become dense and compacted. Minimizing pesticide use is beneficial for improving soil health and microbial diversity and increasing soil microbial populations. Broad-spectrum herbicides are those that kill or control a wide variety of pests including weeds, fungi, and insects. Since they are so non-selective, they can kill or control beneficial microbes as well as both targeted and non-targeted organisms. Often broad-spectrum pesticides may also harm pollinators and beneficial predators. When this happens, ...
