Fall planting is here! The most ideal varieties and trait packages have been selected, your chemical program is planned, but have you considered the importance of a strong crop nutrition program to give your crop the best shot at success?
Crop nutrition can impact two resistance mechanisms for pests:
Studies show tomato susceptibility to fusarium crown and root rot is much greater in the presence of ammonium nitrogen compared to nitrate nitrogen. A study also found that nitrate-nitrogen inhibits disease development and decreases the effects of fusaric acid – a toxin released by pathogens.
Adequate nitrogen levels are needed for disease resistance. However, excess nitrogen or an imbalance with other nutrients can promote favorable conditions to disease. This makes it critical to pay attention to your sources of nitrogen as well as determining the proper balance within your crop fertility program.
Calcium can impact a plant’s susceptibility to disease in two ways:
A deficiency of potassium can impair the synthesis of high-molecular-weight compounds (proteins, starch, and cellulose) and low-molecular-weight organic compounds will accumulate. Potassium can also prevent disease attacks by promoting the development of thicker outer walls in epidermal cells. Plants deficient in potassium have impaired protein synthesis and can accumulate simple N compounds (amides), which are used by invading plant pathogens. Potassium can also influence plant metabolism.
