Abstract:
In order to prevent the spread of cryptic invasive pests, a model on-site biorational dip protocol was developed by evaluating the phytotoxicity and efficacy of Naturl Oil (soybean oil), WetcitTM(alcohol ethoxylate), Publix Soap (nonylphenol ethoxylate), and Vapor Gard (di-1-p-menthene) at varying concentrations on coleus cuttings infested with Phenacoccus madeirensis Green. Efficacy was achieved with 1.0% Naturl Oil (76.09%) and 0.1% WetcitTM (74.99%) by Day 3 and reached highest mortality by Day 14 with 1.0% Naturl Oil (90.97%) and 0.1% WetcitTM (90.47%). Six of the key foliage phytotoxicity ratings for 0.1% WetcitTM were also higher than 1.0% Naturl Oil: chlorosis, chlorotic flecking, necrotic flecking, holes, tip chlorosis, and tip necrosis. Subsequently, 1.0% Naturl Oil was selected as the model dip treatment and compared to other Naturl Oil concentrations for determining exposure time and host plant efficacy. Exposure time efficacy for 1.0% was attained by Day 7 with the 30 (71.81%), 60 (72.54%), and 120 (80.24%) second dip and reached highest mortality with the 30 (87.82%), 60 (88.21%), and 120 (92.00%) second dip by Day 14.Verbena efficacy was achieved by Day 7 for 1.0% (80.74%) and 1.5% (85.85%) and attained highest mortality by Day 14 with 1.0% (80.74%) and 1.5% (85.85%). Mint efficacy for 1.0% (82.71%) and 1.5% (96.89%) was also reached by Day 7 but 1.5% (96.89%) had the highest mortality by Day 14. Overall, 1.0% Naturl Oil as a 30 second dip was determined as the model on-site dip protocol for treating infested ornamental cuttings.
