Liming to Reduce Disease and Rot

With harvest fast approaching stalk quality is a hot topic. This time of year the only thing one can do to minimize loss from disease is harvest early. However it is time to take steps to reduce or prevent rots and disease for next year.

Now is the time to soil sample and plan lime applications.

Low pH may also be the cause of many stalk and stand problems. Having proper pH can reduce the amount and severity of diseases, while increasing the availability of nutrients already present in the soil. According to Plant Pathology, by George Nicholas Agrios, calcium reduces the severity of rhizoctonia, sclerotium (white mold), fusarium, and nematodes. The Plant Pathologist's Pocketbook states, calcium generally enhances resistance against disease, including post-harvest diseases.

Soil pH, calcium level, nitrogen form, and the availability of nutrients plays a major role in disease management. Adequate crop nutrition makes plants more tolerant of or resistant to disease. A direct correlation between adequate calcium levels, and pH, and decreasing levels of Fusarium occurrence has been established for a number of crops, including tomatoes, cotton, melons, and several ornamentals.

Too much phosphate can also be critical. Increasing phosphorus rates above the level needed to grow the crop can increase the severity of Fusarium wilt in certain crops. Avoid applying excessive levels of nitrogen. High N:K ratios have increased severity of many diseases. Work to maintain an adequate level of calcium and potassium in the soil

Don’t forget about fall-seeded crops.
In a study conducted by Washington State University, the incidence of Cephalosporium stripe decreased significantly when soil pH was raised from 5.1 to 6.0. Grain-yield and test weight increased significantly with increasing soil pH in three out of four years.
If you’re planning on sowing wheat, don’t forget to lime. SuperCal 98G can be used as a seed carrier to reduce lime costs, and increase yields.
