Title: Efficacy of Management Tools for Armored Scale in Ground Protocol #:

Transcription

1 Protocol #: p 1 of 5 Objective: Determine efficacy of various products against armored scale on ornamental plants in ground. Do not conduct in containerized ornamentals. Experimental Design: Plot Size: Must be adequate to reflect actual use conditions. Replicates: Minimum of 6 replications. Target Species: Camellia, Euonymus, Japanese Maple, and Tea scales. Contact your regional coordinator if other target species are of interest. Plant Hosts: Use a plant host suitable for target scale species, recording species and variety used. Record crop species and variety used. Treatments: See treatment table on next page. Test materials should have been stored for no more than 2 years prior to start of experiment. Biological test materials should be requested within 2 weeks prior to first application unless otherwise directed by manufacturer. Application Instructions: Apply each treatment according to directions in the table below. All treatments are foliar applications. Applications should be made using application equipment consistent with conventional commercial equipment. Calibrate application equipment prior to application. Read available labels before making applications. Avoid treating plants under unusually extreme environmental conditions. Use Site: Field In Ground. For greenhouse or field container, refer to protocol Evaluations: Record initial insect counts and then 7, 14 (prior to 2 nd application), 28 days, and six months after initial application or at an appropriate time point to assess efficacy. Record phytotoxicity at each rating date on a scale of 0 to 10 (0 = no phytotoxicity; 10 = complete kill). If phytotoxicity is observed in treated plants, take pictures comparing treated and untreated plant material. Maintenance Applications: Applications during an experiment to manage non target diseases, pests or weeds may be needed to appropriately evaluate efficacy or crop safety. Because of potential negative impacts due to simultaneous or sequential applications of certain products with test materials please avoid applying the following: If applications must be made of any products on the above list, please contact IR-4 prior to application. Recordkeeping: All operations, data and observations appropriate to this study should be recorded. It is helpful to review the Ornamental Horticulture Research Report Form in advance. Keep detailed records of weather conditions including temperature, precipitation and/or irrigation, and relative humidity with a minimum of high, low and average daily temperatures. Other information to record includes soil-type or soil-less media, application equipment, irrigation (type & frequency), liner size, plant height & width, and plant growth stage at application and data collection dates. Content of reports should be sufficient to fully understand how the experiment was conducted. Photographs often illustrate experimental design, site conditions, sampling methods, and impacts of treatments very well. It is encouraged to include a picture or two of the greenhouse, field or landscape where the experiment is sited. It is highly encouraged that pictures illustrating treatment effects are taken if and when these impacts are visually apparent. If different application methods or evaluations are made, please clearly specify differences in final report and explain reason for change.
