General Information


ECHO is an excellent disease control agent when used according to label directions for control of a broad spectrum of plant diseases. ECHO is recommended for use in programs that are compatible with the principles of Integrated Pest Management (IPM), including the use of disease resistant crop varieties, cultural practices, pest scouting and disease forecasting systems which reduce unnecessary applications of pesticides.


ECHO is intended to be diluted into water, then applied to crops by typical agricultural spraying techniques. Always apply ECHO in sufficient water to obtain thorough, uniform coverage of foliage and crop surfaces intended to be protected from disease. Spray volume to be used will vary with crop and amount of plant growth. Spray volume should normally range from 20 to 150 gallons per acre (200 to 1400 liters per hectare) for dilute sprays and 5 to 10 gallons per acre (50 to 100 liters per hectare) for concentrate ground sprays and aircraft applications. Both ground and aircraft methods of application are recommended unless specific directions are given for a crop.

Do not use on greenhouse-grown crops.

Do not combine ECHO in sprayer tank with pesticides, surfactants or fertilizers, unless your prior use has shown the combination physically compatible, effective and noninjurious under your conditions of use.

Do not combine ECHO with Dipel 4L, Foil, Triton AG-98, Triton B-1956 or Latron B-1956, as phytotoxicity may result from the combination when applied to the crops on the label.

DO NOT tank mix Echo with oil, or with any adjuvants which contain oil as their principal ingredient.

Do not use with Copper-Count N in concentrated spray suspensions.

For chemigation information application, please refer to the label.


Dosage rates on the label indicate lbs of ECHO 90DF per acre, unless otherwise stated. Under conditions favoring disease development, the high rate specified and shortest application interval should be used.

For each crop use situation, the listed maximum individual and seasonal application rates must not be exceeded and the listed minimum retreatment intervals must not be decreased.

Limitations, Restrictions, and Exceptions


- For control of Late blight, Early blight and Vine rot.

- Begin applications at the low rate (0.625 lbs/acre) when vines are first exposed and leaf wetness occurs. Repeat applications at 7 to 10 day intervals.

- Begin applying the higher label rates (0.875 to 1.25 lbs/acre) at 5 to 10 day intervals when any one of the following events occur:

(1) Vines close within the rows;

(2) Late blight forecasting measures 18 disease severity values (DSV);

(3) The crop reaches 300 P-days

- Increase water spray volume as canopy density increases. Use the highest rate and shortest interval when plants are rapidly growing and disease conditions are severe.

- For chemigation information application, please refer to the label.
