In an article by Anne Dorrace of the Agronomic Crops Network in association with The Ohio State University, Research is showing that the time to worry about next year’s crops is now. Multiple soy bean pathogens are developing into overwinter disease growth operations. Diaporthe Stem Canker and Cercospora Leaf Blight are only two of the pathogens mentioned throughout the article.
Due to warmer winters these diseases that are relevant to Ohio Soy Bean production are starting to develop at the end of crop growth and carry over to next planting season. These diseases are rapidly growing. With warm weather and rain the diseases can be carried from plant to plant by water flow or wind. The growth of these diseases of the foliage of plants is noticeable and can be identified. The first step to healing crops is identifying the problem.
Without proper treatment farmers are going to set themselves up for failure before even planting. The Key is to fight the disease as soon as it develops on 2017 crops. After a first does of Phytophthora or any other resistance package, continue regulated use.
These diseases are rapidly growing. With warm weather and rain the diseases can be carried from plant to plant by water flow or wind.
A few more tips include crop rotation, proper tilling practices, and the use of high quality disease free feed. By planting resistant varieties of soy beans any farmer can decrease crop death from disease. Fungicide applications after planting are helpful but there is no promise of even distribution.
