Eastern Peach Pest Management Strategies for Adapting to Changing Management Options


StateFlorida, Georgia, Michigan, North Carolina, New Jersey, Pennsylvania, South Carolina


Executive Summary



Category Rank Pest Type Pest Crop Stage Date Priority
Extension/Outreach 1 All Pest Types 2000 Integrated Orchard Management (IOM and its pest management components) carry considerable management costs that are seldom given due weight for high-value commodities such as peaches. Growers, especially processing growers, need orchard consultants to successfully implement increasingly complex pest management options. The economics of pest management must be re-examined in light of its non-farm benefits to society in order to sustain a badly need cadre of pest management consultants. Integrated Orchard Management is a key element of both worker safety and environmental stewardship.
Extension/Outreach 2 All Pest Types 2000 Best management practices for mitigating in-orchard spread of virus and other systemic tree diseases has become an industry priority.
Regulatory 1 All Pest Types 2000 Peaches are highly dependent on hand labor. Step-wise, acute and cumulative, in-orchard quantification of worker exposure to key pesticides is needed for all key activities.
Regulatory 2 All Pest Types 2000 Regulatory decisions on re-entry intervals (REIs) need to recognize the need to conduct field essential activities and such decisions should take into effect cost/benefits considerations.
Regulatory 3 All Pest Types 2000 Regulatory decisions on OPs have extended preharvest intervals (PHIs). However the need to for late season insect control and the effects on IPM programs with longer PHIs needs to be fully considered in regulatory decisions and in the evaluation of mitigation options
Regulatory 4 All Pest Types 2000 American produce growers, including peach growers, should receive assurance that foreign producers will be held to U.S. standards for pesticide labels. Tolerances should not allow foreign competitors unfair advantages.
Regulatory 5 All Pest Types 2000 Resistance management is a key concern with orchard pests. Rotating pesticides to expose pests to varied modes-of-action is the most feasible management option. Regulatory decisions should thoroughly consider resistance management concerns. It is imperative to maintain multiple modes-of-action for use against key pests.
Regulatory 6 All Pest Types 2000 Critical point analysis (HACCP) for both microbial and pesticide residue risks is badly needed to model risks from harvest through shipment.
Regulatory 7 All Pest Types 2000 Region-wide virus and phytoplasma tree-health programs are needed to mitigate potential spread of plum pox virus (PPV) and reduce the incidence on less catastrophic, endemic viruses. Nursery certification and elimination of non-certified stocks is an industry priority.
Research 1 All Pest Types 2000 Re-inventing eastern peach IPM must first focus on pest biology for peach pests: insects, mites, diseases, nematodes and weeds, along with their complements of natural enemies, to develop a currently lacking, prerequisite knowledge base. Improved understanding of biology is needed to form the foundation for creating biologically-refined monitoring and predictive tools for key peach pests.
Research 2 All Pest Types 2000 Plum curculio (PC) in the Southeast and Oriental fruit moth (OFM) in the mid- Atlantic and upper mid-West are the key fruit insect pests. Even the modest reduction in organophosphate achieved to date, have facilitated observable elevations in the pest status of both PC and OFM in those areas where they are presently subordinate pests. Pest biology and behavior studies for PC and OFM are key prerequisites to development of more evolved IPM options.
Research 3 All Pest Types 2000 Low risk insecticides that do not promote scale problems are badly needed for stink bugs and opportunistic fruit pests. Stink bugs and tarnished plant bugs in particular are a concern. These pests damage fruit and they can be important mechanical vectors of brown rot.
Research 4 All Pest Types 2000 Scale, primarily San Jose and white peach, have become damaging primary pests. This elevation in pest status is attributable to changes in pesticide availability. Research should focus on scale biology and model development to improve timing of insecticide applications.
Research 5 All Pest Types 2000 Beetles (Japanese, green June, rose chafers & white fringed) are occasionally very difficult to control. Research needs need to include these occasional but highly problematic pests
Research 6 All Pest Types 2000 Efficacy trials of lower-risk insecticides and biorational controls must be conducted. Impacts on key, secondary and induced pests; beneficials; and “new” pests must be carefully studied. Promising options must be incorporated into existing commercial practice.
Research 6 All Pest Types 2000 Brown rot is the East’s key fruit rot of peach. De-methylation inhibitor (DMI)- based control programs are excellent, but the brown rot organism readily develops fungicide resistance. A fuller understanding of the pathogen’s biology and epidemiology is needed to improve timing of sprays and develop prudent resistance management strategies.
Research 7 All Pest Types 2000 At present, some 20% of the bearing peach acreage is planted to cultivars susceptible to bacterial spot. Chemical control is solely dependent on materialsthat face regulatory scrutiny. Pesticide resistance is a major concern. Host plant resistance is important and is being used. However, all but the most resistant cultivars need supplemental chemical control when pest pressure is high. A better understanding of pest biology and examination of lower-risk control options are essential.
Research 8 All Pest Types 2000 Research is needed to determine optimal weed-free intervals for early-, midand late-season peaches. In-row cover crops must be evaluated as a potential means of reducing herbicide use and controlling weeds during at least part of the annual production cycle. New herbicides must be evaluated as potential replacements, especially for simazine and 2,4-D.
Research 9 All Pest Types 2000 Research on nematode control must focus on pest biology, resistant rootstocks and cultural controls. More environmentally favorable alternatives to methyl bromide are badly needed, especially in the tree nurseries
