Purpose Quantify benefits of IPM practices in tobacco Identify barriers to IPM adoption by tobacco growers Enhancing IPM in tobacco

2014 activities Research station trials Small plot experiments focused on insecticide application frequency and residues On farm trials Large plot experiments focused on comparing IPM recommendations to grower practices Enhancing IPM in tobacco

Enhancing IPM in tobacco On farm trials Three locations (Stokes, Johnston, Wilson) Grower standard & IPM plots Collected insect data, scouting time, insecticide inputs, yield Shared results weekly via Tobacco Portal

Enhancing IPM in tobacco On farm trials Key results Scouting time averaged 4.4 min/acre Meaning, a grower with 100 acres of tobacco could expect 1 day/week of scouting (7.4 hours) **This may be an overestimate as scouted fields were small**

Enhancing IPM in tobacco On farm trials Key results Pest pressure similar across fields

Enhancing IPM in tobacco On farm trials Key results Pest pressure similar across fields

Enhancing IPM in tobacco On farm trials Key results Yield similar across fields

Enhancing IPM in tobacco On farm trials Future directions Expand to more locations—seeking sites in Lee, Moore, Richmond, Scotland, Robeson, Columbus, Granville, Person, or Franklin Counties Refine scouting recommendations

We plan to conduct a grower survey at 2015 GAP meetings to refine our understanding of grower- perceived barriers to IPM adoption HELP! Enhancing IPM in tobacco Grower feedback

Pesticide labels and pollinator protection Pollinator protection language pre 2014 Remains on labels!

Pesticide labels and pollinator protection Pollinator protection language pre 2014

Pesticide labels and pollinator protection Appear on Group 4A (neonicotinoid) and some Group 28 labels Will eventually appear on all labels when materials impact pollinators

Pesticide labels and pollinator protection Admire Pro No specific pollinator protection restrictions for tobacco Important to note that non crop applications are not allowed unless specified on label!

Pesticide labels and pollinator protection What do these label changes mean for tobacco growers? Apply primarily to foliar applications Systemic neonicotinoid applications meet current label restrictions As additional labels are updated, may have greater impact – growers should be aware of precautions and follow best management practices regardless Pollinator Task Force (coordinated through NC Farm Bureau)
