We know that insect and disease pressure often begins in one area of a field. Insects do not show up in fields at random. Instead, they are attracted to plants transmitting specific stress signals. These stress signals can be the result of extreme soil or weather conditions such as saturated soil or high temperatures, but they are most commonly a result of nutritional imbalances. When nutrients are imbalanced within the plant, the result is an altered plant physiology. Carbohydrate profiles and the balance of various forms of nitrogenous compounds all adjust to reflect the plant’s mineral nutritional integrity. In this presentation, John Kempf will describe how to manage nutrition to produce plants that are more resistant to insects at all stages of plant growth, ranging from flea beetle pressure at the seedling stage on canola, to insects which feed on fruit or grain.
