Corn hybrid selection and fertility planning are key in alkaline, or high pH, soils. High-pH soils reduce the availability of plant nutrients, including zinc, iron and phosphorus. Interveinal yellow stripes on middle to upper leaves are signs of iron deficiency, while white stripes on young leaves are characteristic of zinc deficiency. Dark green or purple coloring of lower leaves indicates phosphorus deficiencies.

With so many Bt trait offerings on the market today, it can be challenging to determine which package best fits your farm. Each package contains different combinations of traits with different levels of effectiveness against specific pests.
