PMSP for Pecans in the Southeastern US

Priorities

Category Rank Pest Type Pest Crop Stage Priority
Extension/Outreach 1 6- to 12-Inch Shoot Weed control manuals for all winter annual weeds.
Extension/Outreach 1 Insects 6- to 12-Inch Shoot development of a regional IPM website for pecan management as a tool to deliver technology transfer to growers
Extension/Outreach 2 6- to 12-Inch Shoot Increase presence of weed control information in production guides for all winter annual weeds..
Extension/Outreach 2 Insects 6- to 12-Inch Shoot increase extension funding for technology transfer
Extension/Outreach 3 Pathogens 6- to 12-Inch Shoot integrated orchard management carry considerable management costs
Regulatory 1 6- to 12-Inch Shoot Allow registration of herbicide for use in tree limbs for all winter annual weeds.
Regulatory 1 6- to 12-Inch Shoot expedite registration of new nematicides and other control tactics as they become available
Regulatory 1 Insects 6- to 12-Inch Shoot expedite registration of new fungicides and other control tactics as they become available
Regulatory 2 Insects 6- to 12-Inch Shoot develop and implement a program that will allow researchers to test new chemistries on up to 250 acres prior to full registration
Regulatory 3 Insects 6- to 12-Inch Shoot encourage regulatory procedures to maintain diversity of chemical disease control options for resistance management to maximize long-term disease control
Research 1 6- to 12-Inch Shoot Identification of new pre-emergence herbicide alternatives to simazine and diuron. Such alternatives need to have favorable environmental profiles, provide broadspectrum, long, term residual control.
Research 1 Insects 6- to 12-Inch Shoot influence of cultural practices (nutrition, pruning, hedging) on disease and development
Research 2 6- to 12-Inch Shoot Woody perennial plants are difficult to control. There is a need for an alternative to glyphosate for controlling undesirable woody perennial plants. Trees can become sensitive to glyphosate applied in late summer and fall. Application time is specific for individual species requiring increased management in orchards where 2 or more perennial weed species are a problem.
Research 2 Insects 6- to 12-Inch Shoot effectiveness of fungicide resistance management strategies on pecan
Research 3 6- to 12-Inch Shoot Mistletoe is a parasitic weed that can cause significant yield loss. Control depends on physical removal of infected tree limbs. Limb removal reduces tree productivity.
Research 3 Insects 6- to 12-Inch Shoot reduced inputs for scab management
Research 4 6- to 12-Inch Shoot Screen herbicides for mistletoe efficacy and crop tolerance for all winter annual weeds.
Research 4 Insects 6- to 12-Inch Shoot genetic variability in scab and develop resistant varieties to scab (assessment of genotypes as resources for breeders)
Research 5 6- to 12-Inch Shoot Investigate the opportunity for biological controls.
Research 5 Insects 6- to 12-Inch Shoot molecular characterization of scab resistance
Research 6 Insects 6- to 12-Inch Shoot effect of genotype diversity (host mixtures) by row on reduction of scab (disease management)
Research 7 Insects 6- to 12-Inch Shoot evaluation of new fungicides on minor crops like pecan
Research 8 Insects 6- to 12-Inch Shoot improved fungicide application technology for disease management (reduce inputs)
Research 9 Insects 6- to 12-Inch Shoot evaluation of currently registered strobilurin fungicides for downy spot control
Research 10 Pathogens 6- to 12-Inch Shoot management of downy spot, in the absence of scab control or on scab resistant varieties
Research 11 Insects 6- to 12-Inch Shoot timing of fungicide applications for most effective disease control, relative to availability of initial inoculum and host susceptibility
Research 12 Insects 6- to 12-Inch Shoot evaluation of scab-resistant pecan cultivars for resistance to this and other secondary diseases
Research 13 Insects 6- to 12-Inch Shoot management options for Phytophthora shuck and kernel rot
Research 14 Insects 6- to 12-Inch Shoot need data on efficacy of currently registered strobilurins (azoxystrobin, kresoximmethyl, pyraclostrobin), strobilurin mixtures (Stratego), DMI/fentin hydroxide mixtures, ziram, dodine, and dodine/fenbuconazole mixtures on Phytophthora shuck and kernel rot
Research 15 Insects 6- to 12-Inch Shoot need more quantitative info on economic impact of Phytophthora shuck and kernel rot and yield loss
Research 16 Insects 6- to 12-Inch Shoot evaluation of scab-resistant pecan cultivars for resistance to this other secondary diseases
Research 17 Insects 6- to 12-Inch Shoot quantitative effects of sooty mold on pecan yield and production
Research 18 Insects 6- to 12-Inch Shoot etiology/taxonomy of sooty mold fungi on pecan
Research 19 Insects 6- to 12-Inch Shoot influence of cultural practices (nutrition, pruning, hedging) on disease development
Research 20 Insects 6- to 12-Inch Shoot management options for sooty mold
