Title: Efficacy of Management Tools for Armored Scale in Containers
Protocol #: 15-006
Draft
p 1 of 4
Objective: Determine efficacy of various products against armored scale on ornamental plants in containers.
Do not conduct this protocol with in-ground plants.
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: May be greenhouse or field container. For field in-ground, refer to protocol 14-007.
Evaluations: Record initial insect counts and then 7, 14 (prior to 2nd 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.
