Objective: Determine phytotoxicity of soil applied fungicides on various ornamental horticulture plants.
Experimental Design:
Use Site: Greenhouse.
Plot Size: Must be adequate to reflect actual use conditions.
Replicates: Randomized block design with a minimum of 4 plants per 3 blocks OR completely randomized
design with a minimum of 10 plants.
Plant Materials: Please visit the IR-4 website or contact your regional coordinator.
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: A single (1) drench application should be made. Plants should be actively
growing and flushing new growth at time of application. 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.
Evaluations: Record plant height & width at initial and final evaluations only. At 7, 14 and 28 days after
application, record phytotoxicity on a scale of 0 to 10 (0 = No phytotoxicity; 10 = Complete kill). If
appropriate, also include ratings for chlorosis, defoliation, discoloration, stunting or other growth effects
on a scale of 0 to 10 (0 = No effect; 10 = Complete plant affected). If possible, hold plants until
flowering and record any issues with flowers, such as damage, flower bud development, number of
flowers, or delay in flowering. If any 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 andperor irrigation, and relative humidity with a minimum of high, low
and average daily temperature. 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, 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.

Special Instructions
Single Drench. Apply 1-2 pints per square foot
surface area.
Make application as a drench to the soil. Mix to
100 gal and then note in your report what the
dranch rate was depending on your plant size and
container size. For example, “drenched at 255 ml
per 6 inch container”. Always water containers the
night before the application and never make the
application to dry soil. Two applications can be
made at a 21 – 28 day interval.
Single Drench. Apply 2 pints per square foot
surface area.
Single Drench. Apply 1-2 pints per square foot
surface area.
