How to Identify and Control Pecan Phylloxera

Pecan phylloxera is an insect that can cause significant damage if ignored or treated incorrectly in pecan orchards. Phylloxera can attack shoots, leaves and fruit of pecan trees. Due to the life cycle of phylloxera, timing is very important to treating the infestation. Once you see galls, it is already too late to stop the infestation.

Drought Stress on Pecan Trees

Drought conditions cause extreme stress on pecan trees. Water is critical for tree survival and nut production, and is involved in all processes within the trees, ranging from nutrient transportation to the production of leaves and fruit. It is important for producers to understand the effects of drought and how pecan trees cope with the stress it brings.

Cross pollination is essential for pecan production

Pollination in the pecan orchard is critical to both the yield and quality of nuts. Pecan trees are cross-pollinated (allogamous) and although self-pollination is possible, the result is largely unsuccessful. Pecan trees are wind-pollinated; therefore, pollinators (i.e., bees) are not required to complete pollination. Cross-pollinated pecans are usually larger and higher quality than self-pollinated pecans. Self-pollination can reduce nut quality and greatly reduce crop yield by as much as 75 percent.
