Product Information 

This label must be in the possession of the user at the time of fungicide application. 

Carefully read and understand the Directions For Use and Restrictions and Limitations before applying this 

product. 

OrvegoTM fungicide may be applied to field-grown and containerized ornamental and nursery plants for the control of 

downy mildew and phytophthora root, crown, and stem diseases in the following use sites: 

• Greenhouses, lathhouses, and shadehouses 

• Hardwood and conifer nurseries or plantations 

• Interiorscapes 

• Outdoor or field nurseries 

Orvego may be applied as a foliar spray, soil drench, directed or soil surface spray, or through irrigation systems. For 

use rate and spray interval, see instructions specific to use site, disease, and plant type. See OrvegoTM fungicide

Disease Control tables for application methods, rates, and timings. 
5

Mode of Action 

OrvegoTM fungicide contains two active ingredients: ametoctradin and dimethomorph. Ametoctradin is a strong 

inhibitor of mitochondrial respiration in complex III (cytochrome bc1) of oomycetes fungi. The active ingredient is 

classified by the Fungicide Resistance Action Committee (FRAC) as a Group 45 fungicide because the exact binding 

site is not yet known. Dimethomorph belongs to the group of cell-wall synthesis inhibitors and target-site-of-action 

Group 40 fungicides. 

Orvego is used for the preventive control of certain foliar, stem, and root diseases of herbaceous and woody 

ornamental crops. Orvego can be used on plants grown in greenhouses, lathhouses, shadehouses, interiorscapes, 

and outdoor container or field nurseries, including hardwood and conifer nursery seedlings. Use this product in a 

program with other products to provide season-long protection. Under severe disease conditions, use maximum rates 

and shorter intervals for repeat applications. 

Orvego is a foliar and root penetrant with translaminar and locally systemic activity. Thorough plant coverage is 

important when Orvego is used as a preventive application for foliar diseases. Dense foliage or excessive growth will 

often prevent adequate coverage; adjust spray volumes accordingly. Orvego will also control stem and root diseases 

when applied to the root zone of the plant as a drench, soil surface, or directed spray, or via hydroponic and 

chemigation systems. 

Carefully read, understand, and follow all directions and precautions. 

Disease pressure and environmental conditions will determine the length of the spray interval. Calibrate sprayers 

before application. 

Resistance Management 

The multiple modes of action of Orvego make it ideal for disease management programs where fungicide rotation is 

emphasized to help prevent the development of resistance. 

Certain causal agents of downy mildew diseases (Bremia spp., Peronospora spp., Phytophthora spp., 

Plasmopara spp., and Pseudoperonospora spp. strains) have developed resistance to some crop protection products 

after excessive use. Because the development of resistance cannot be predicted, always use Orvego in a resistance 

management program that incorporates the practices of alternation (rotation) and/or tank mixing Orvego with other 

fungicides effective on downy mildew and Phytophthora diseases. 

Apply Orvego in an alternation or tank mix program with other registered fungicides that have a different mode of 

action. 

DO NOT apply more than 2 consecutive applications of Orvego to a crop unless tank mixed. Between Orvego use, 

rotate to products with different modes of action for 2 applications. 

If disease continues to increase excessively after Orvego treatment when used according to label directions, DO NOT

increase the use rate beyond the labeled rate. Discontinue Orvego use and switch to another fungicide with a different 

target site or mode of action, if available. Your local crop advisor can provide an appropriate control strategy. 

Orvego is a protectant fungicide. If not applied on a routine protectant spray schedule, examine crops weekly for signs 

and symptoms of disease. Make fungicide application at the specified label use rate and spray schedule, at the first 

sign of disease, or during environmental conditions favorable for disease development. Resistance management 

strategies advise not to apply at rates lower than specified on the label. 

Directions For Use Through Sprinkler Irrigation Systems 

Orvego may be applied as a chemigation treatment through sprinkler irrigation systems. 

Pesticide supply tanks are recommended for the application of pesticide products. See label instructions for dilution 

use rates and timing of applications. Agitate before use and during application. Because the material is used in an 

injection proportioner, apply the pesticide continuously for the duration of the water application. 

Apply this product only through pressurized drench (flood), sprinkler, or drip (trickle) irrigation systems. DO NOT apply 

this product through any other type of irrigation system. 

Crop injury or lack of effectiveness can result from nonuniform distribution of treated water. 

Contact a state extension service specialist, equipment manufacturers, or other experts for calibration questions. 
6

DO NOT connect an irrigation system (including greenhouse systems) used for pesticide application to a public water 

system unless the pesticide label-prescribed safety devices for public water systems are in place. 

A person knowledgeable of the chemigation system and responsible for its operation or under the supervision of the 

responsible person shall shut the system down and make necessary adjustments should the need arise. 

Use Precautions for Sprinkler Irrigation Applications for Pressurized Drench (Flood) 

System, Sprinkler (Spray) Chemigation, and Drip (Trickle) Chemigation 

Systems using a pressurized water and pesticide injection system must meet the following requirements: 

• The system must contain a functional check valve, vacuum-relief valve, and low-pressure drain appropriately located 

on the irrigation pipeline to prevent water-source contamination from backflow. 

• The pesticide injection pipeline must contain a functional, automatic, quick-closing check valve to prevent the flow of 

fluid back toward the injection pump. 

• The pesticide injection pipeline must also contain a functional, normally closed, solenoid-operated valve located on 

the intake side of the injection pump and connected to the system interlock to prevent fluid from being withdrawn 

from the supply tank when the irrigation system is either automatically or manually shut down. 

• The system must contain functional interlocking controls to automatically shut off the pesticide injection pump when 

the water pump motor stops. 

• The irrigation line or water pump must include a functional pressure switch which will stop the water pump motor 

when the water pressure decreases to the point where pesticide distribution is adversely affected. 

• Systems must use a metering pump, such as a positive displacement injection pump (e.g. diaphragm pump), 

effectively designed and constructed of materials that are compatible with pesticides and capable of being fitted with 

a system interlock. 

• DO NOT apply when wind speed favors drift beyond the area intended for treatment. 

Specific Instructions for Public Water Systems 

1. Public water system means a system for the provision to the public of piped water for human consumption if such 

system has at least 15 service connections or regularly serves an average of at least 25 individuals daily at least 

60 days out of the year. 

2. Chemigation systems connected to public water systems must contain a functional, reduced-pressure zone, backflow preventer (RPZ), or the functional equivalent in the water supply line upstream from the point of pesticide 

introduction. As an option to the RPZ, the water from the public water system should be discharged into a reservoir 

tank prior to pesticide introduction. There shall be a complete physical break (air gap) between the outlet end of the 

fill pipe and the top or overflow rim of the reservoir tank of at least twice the inside diameter of the fill pipe. 

3. The pesticide injection pipeline must contain a functional, automatic, quick-closing check valve to prevent the flow of 

fluid back toward the injection pump. 

4. The pesticide injection pipeline must contain a functional, normally closed, solenoid-operated valve located on the 

intake side of the injection pump and connected to the system interlock to prevent fluid from being withdrawn from 

the supply tank when the irrigation system is either automatically or manually shut down. 

5. The system must contain functional interlocking controls to automatically shut off the pesticide injection pump when 

the water pump motor stops, or in cases where there is no water pump, when the water pressure decreases to the 

point where pesticide distribution is adversely affected. 

6. Systems must use a metering pump, such as a positive displacement injection pump (e.g. diaphragm pump), 

effectively designed and constructed of materials that are compatible with pesticides and capable of being fitted with 

a system interlock. 

Mixing Instructions 

Fill the spray tank until it is approximately 1/2 full with clean water. Shake the OrvegoTM fungicide container well; then 

slowly add Orvego to the spray tank while agitating. Agitation must be engaged before the addition of the product to 

obtain a complete and uniform mixture of Orvego. 

Limit amount of spray mixture prepared to that needed for immediate use.

Orvego can be tank mixed with most recommended fungicides, insecticides, herbicides, liquid fertilizers, biological 

control products, adjuvants, and additives. 

If tank mixtures are used, follow rate restrictions, label directions, and precautions on all labels. 

Under some conditions, the use of additives or adjuvants may improve the performance of Orvego. However, all 

varieties and cultivars have not been tested with possible tank mix combinations. Local conditions can also influence 

plant tolerance and may not match those under which BASF has conducted testing. Physical incompatibility, reduced 
7

disease control, or plant injury may result from mixing OrvegoTM fungicide with other products. Therefore, before 

using any tank mix (fungicides, insecticides, herbicides, liquid fertilizers, biological control products, adjuvants, and 

additives), test the combination on a small portion of the plant to be treated to ensure that a phytotoxic response will 

not occur as a result of application. 

Consult a BASF representative or local agricultural authorities for more information concerning additives. 

Compatibility Test for Tank Mix Components 

Add components in the following sequence using 2 teaspoons for each pound or 1 teaspoon for each pint of label rate 

per acre. 

1. Water - For 100 gallons per acre spray volume, use 16 cups (1 gallon) of water. For other spray volumes, adjust 

rates accordingly. Use only water from the intended source at the source temperature. 

2. Water-dispersible products (dry flowables, wettable powders, suspension concentrates, or suspo-emulsions) - 

Cap the jar and invert 10 cycles. 

3. Water-soluble products - Cap the jar and invert 10 cycles. 

4. Emulsifiable concentrates [oil concentrate or methylated seed oil (MSO) when applicable] - Cap the jar and invert 

10 cycles. 

5. Water-soluble additives - Cap the jar and invert 10 cycles. 

6. Let the solution stand for 15 minutes. 

7. Evaluate the solution for uniformity and stability. The spray solution should not have free oil on the surface, or fine 

particles that precipitate to the bottom, or thick (clabbered) texture. DO NOT use any spray solution that could clog 

spray nozzles. 

Mixing Order 

1. Water - Begin by agitating a thoroughly clean sprayer tank 3/4 full of clean water. 

2. Agitation - Maintain constant agitation throughout mixing and application. 

3. Inductor - If an inductor is used, rinse it thoroughly after each component has been added. 

4. Products in PVA bags - Place any product contained in water-soluble PVA bags into the mixing tank. Wait until all 

water-soluble PVA bags have fully dissolved and the product is evenly mixed in the spray tank before continuing. 

5. Water-dispersible products (such as Orvego, dry flowables, wettable powders, suspension concentrates, or 

suspo-emulsions) 

6. Water-soluble products 

7. Emulsifiable concentrates (such as oil concentrates when applicable) 

8. Water-soluble additives [such as ammonium sulfate (AMS) or urea ammonium nitrate (UAN) when applicable] 

9. Remaining quantity of water 

Ensure each component is thoroughly mixed and suspended before adding tank mix partners. Maintain constant 

agitation during application.
