Pecan anthracnose is favored by wet environmental conditions and warm temperatures above 80 degrees Fahrenheit. [5] Symptoms include dark lesions on the pecan shuck and leaves.
The trees can also develop yellowish colour on their leaves and veins. [27] Molybdenum availability is increased at higher pH; this is because the molybdate ion is more strongly sorbed by clay particles at lower pH. [28] Zinc, iron, copper and manganese show decreased availability at higher pH (increased sorption at higher pH). [28]

Maize plants with severe zinc deficiency in the foreground, with healthier plants (planted at the same time) in the background. Zinc deficiency is common in many different types of soil; some soils (sandy soils, histosols and soils developed from highly weathered parent material) have low total zinc concentrations, and others have low plant-available zinc due to strong zinc sorption ...
