It is hard to believe that summer is almost upon us. This has the potential to be a heavy pecan crop year, if the drought has not hurt things too badly. To ensure a good crop, many management decisions need to be considered over the next few months, including proper fertilization and insect and disease control.
Fertilization is just one pecan management practice that helps maximize crop production and provides optimal tree maintenance. Proper fertilization encourages growth of shoots and leaves, which is essential for increasing crop load and decreasing tree stress.
Pecan trees exhibit a strong tendency to produce a heavy crop one year, followed by one or more years of little to no production. This may best be characterized as alternate bearing with irregular symmetry.
One of the most damaging diseases in pecans is pecan scab, caused by the fungus Fusicladium effusum. It infects actively growing tissue, such as stems, leaves and nut shucks, when temperatures are above 70 degrees Fahrenheit and relative humidity is above 90 percent.
