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


- Apply this product in sufficient water and with proper calibration to obtain uniform coverage of tree canopy. Application with ground equipment is preferable to aerial application because ground applications generally give better coverage of the tree canopy.

- If application with ground equipment is not feasible, this product may be applied with aircraft using at least 20 gallons of spray per acre. When concentrate sprays are used or when treating non-bearing or immature trees, use the lower rate for the crop being treated.

- DO NOT allow livestock to graze in treated areas.

- DO NOT apply Echo within one week before or after application of oil or an oil-based pesticide


- For control of Swiss needlecast and Scleroderris canker (pines).

- Make additional applications at 3 to 4 week intervals until conditions no longer favor disease development. For use in nursery beds, apply the highest rate specified on a 3 week schedule.

Spray Volume:

5 to 10 gallons/acre - concentrate ground or aircraft

100 gallons/acre - dilute

Restricted Entry Interval
