This pesticide is toxic to fish and aquatic invertebrates and may contaminate water through runoff. This product has a potential for runoff for several months or more after application. Poorly draining soils and soils with shallow water tables are more prone to produce runoff that contains this product. Drift and runoff may be hazardous to aquatic organisms in waters adjacent to treated areas. For terrestrial uses, do not apply directly to water, to areas where surface water is present or to intertidal areas below the mean high water mark. Do not contaminate water when disposing of equipment wash-waters or rinsate.


It is a violation of Federal Law to use this product in a manner inconsistent with its labeling.

Do not apply this product in a way that will contact workers or other persons, either directly or through drift. Only protected handlers may be in the area during application. For any requirements specific to your State or Tribe, consult the State or Tribal agency responsible for pesticide regulation.


Kocide 3000-O may be applied as an aerial, ground dilute or ground concentrate spray unless specifically directed otherwise in the specific crop use directions.

The per acre use rate of Kocide 3000-O is applicable for both dilute and concentrate spraying. Depending upon the equipment used and the specific crop, the spray volume applied per acre will differ. Refer to Minimum Recommended Spray Volume Table. Complete spray coverage is essential to assure optimum performance from Kocide 3000-O. When treating by aerial application or with low volume application equipment, unless you have had specific previous experience, it is advisable to test for compatibility and tolerance to crop injury prior to full scale commercial utilization.

Consult the Kocide 3000-O label for specific rates and timing of application by crop. Where application rates and intervals are provided in a range (e.g., 4 to 12 pounds and 7 to 10 days), use the higher rates and shorter spray intervals when rainfall is heavy and/or disease pressure is high. Use the higher rates for large mature tree crops.


The Pre-Harvest Interval (PHI) for Kocide 3000-O is 0-days unless noted.

  • If Kocide 3000-O is applied in a spray solution having a pH of less than 6.5, phytotoxicity may occur.
  • Do not tank mix Kocide 3000-O with “Aliette” fungicide for use on any registered crops unless appropriate precautions have been taken to buffer the spray solution because severe phytotoxicity may result. Use in accordance with the most restrictive of label limitations and precautions. Do not exceed label dosage rates. This product cannot be mixed with any product containing a label prohibition against such mixing.
  • This product may be reactive on masonry and metal surfaces such as galvanized roofing. Avoid contact with metal surfaces. Do not spray on cars, houses, lawn furniture, etc.
  • Environmental conditions such as extended periods of wet weather, acid rain, etc. which alter the pH of the leaf surface may affect the performance of Kocide 3000-O resulting in possible phytotoxicity or loss of effectiveness.
  • Agricultural chemicals may perform in an unpredictable manner when tank mixed, especially where several products are involved. Reduced effect on pests or crop injury may occur. Unless recommended on this label or by a state/local expert, it is advisable to test for compatibility and potential crop injury prior to commercial use of a new tank mix.
  • It must be determined if proper application equipment is available and if waste associated with its use can be properly handled. Agricultural chemicals are often reactive with the materials used in the construction of application equipment, such as aluminum, rubber and some synthetic materials. This factor should be taken into consideration when selecting proper application equipment. It is necessary that all application equipment be thoroughly flushed with clean water after each day’s use.
  • Apply this product only through one or more of the following types of systems: sprinkler, including center pivot, lateral move, traveler, big gun, or plastic pipe solid set system(s). Do not apply this product through any other type of irrigation system. In California, do not apply in systems which contain aluminum parts or components.
  • While volume is important in obtaining full spray coverage, often factors such as foliage density, environmental conditions and sprayer calibration have a greater impact. Always be sure that sprayers are calibrated to spray equipment manufacturer’s specifications and environmental conditions are within those recommended by State and local regulatory authorities.
  • When mixing, fill the spray tank one-half full with water. Add Kocide 3000-O slowly to tank while hydraulic or mechanical agitation is operating and continue filling with water. Spreaders, stickers, insecticides, nutrients, etc. should be added last. If compatibility is in question, use the Compatibility Jar Test before mixing a whole tank or contact your chemical supplier. Observe all precautions and limitations on the labels of all products used in mixtures.

Is Kocide 3000-O Fungicide/Bactericide the same as Kocide 101?

I need it to kill ball moss on ligustrum and East Palatka holly.


It appears that Kocide 101 is no longer in production. Kocide 3000 contains Copper Hydroxide, though, and it is labeled to treat ball moss on Pecan and Live Oak trees.

How much Kocide 3000-O Fungicide/Bactericide would I use to treat 10 Cherry Trees for black spot? What is the amount per tree and are repeat applications needed?

Kocide 3000-O Fungicide/Bactericide is labeled for Cherry Leaf Spot (sour cherries only) at the rate of 2.25 - 3.5 lb per acre with a maximum of 60lbs per acre per year.

Fungicides with an active ingredient of myclobutanil (Eagle 20EW) or captan (Bondie Captain Fungicide) will protect leaves from infection with cherry leaf spot. To avoid fungicide resistance, alternate between myclobutanil and captan when making repeated fungicide applications

Copper Fungicide (Bonide Liquid Copper) has also shown to show some levels of protection against leaf spot infection.
