Introduction to Pecan IPM
The role of integrated pest management in helping growers reduce pest management costs. Topics include pest management approaches, the interdisciplinary roles of horticulture, entomology and plant pathology in strengthening integrated pest management tactics.
An overview of the basics - the importance of the pecan tree, pecan production in the U.S., pecan history and arthropod management through that history, from the 1800's through 1990.
In horticulture, cultural and physical practices are those activities involved in caring for plants, such as site and cultivar selection, strengthening the landscape so that conditions are favorable for the tree and orchard but unfavorable to pests, creating habitats for beneficial insects, weeding, irrigation, nutrition, etc.
Beneficial organisms fall into two main groups: predators and parasites. This guide discusses description and behavior of beneficial insects in the pecan orchard.
Discussion of the major insect pests in the pecan orchard, how they relate to pecan development stages, grouped by pests of nuts, foliage, and trunks and branches.
Some 20+ species of insects can inflict significant losses to pecan crops. Proper orchard monitoring can ensure these pests are controlled when they approach damaging levels.This IPM tool outlines control suggestions, survey methods and action levels.
Diseases affecting pecans are caused by bacteria, fungi, nematodes, mycoplasma, and physiological problems. This tool discusses diseases such as pecan scab, vein spot, shuck dieback, crown gall, cotton root rot, and the variety of practices used to prevent and treat them.
A list of IPM equipment such as hand lenses, black lights, traps, cages, plus supplier sources and addresses.
A tool for designing a management plan to control destruction by vertebrates in the pecan orchard. Prevention of losses depends largely on early detection and initiation of control measures. Anticipate feeding habits of crows, blue jays and squirrels and initiate measures to deter them.
