It is a misdemeanor to tamper with a tank and a felony to illegally transport anhydrous ammonia. It is now September and USDA Secretary Glickman confirmed the supplemental payments would begin on September 1. Now is a good time to test fields for soybean cyst nematode since it effects beans wherever they are regularly grown. Generally, the more often soybeans are grown in a field, the greater the incidence of cyst nematode. Losses can range from undetectable to over 75 percent of the yield.
Many factors influence the loss.
Some factors include the nematode population, compaction, moisture stress, fertility levels as well as others. The first areas to check are locations that have recurring lower yields as well as areas with reduced growth and plants with yellowing leaf margins. Dig up two or three plants in each location and gently wash the roots. After drying, the cysts will appear as very small nodes similar to nitrogen nodules. However, this does not give an accurate level of infestation.
