PRECAUTIONARY STATEMENTS

Hazards to Humans and Domestic Animals - CAUTION. Harmful if inhaled. Causes 

moderate eye irritation. Avoid contact with eyes or clothing. Avoid breathing spray mist. Wear 

safety glasses or goggles. Wash thoroughly with soap and water after handling and before 

eating, drinking, chewing gum, using tobacco or using the toilet. Remove and wash 

contaminated clothing before reuse.

Personal Protective Equipment (PPE): Applicators and other handlers must wear longsleeved shirt and long pants, waterproof gloves, and shoes plus socks. Mixer/loaders and 

applicators, not in enclosed cabs, must wear a dust/mist-filtering respirator meeting NIOSH 

standards of at least N-95, R-95, or P-95. Repeated exposure to high concentrations of 

microbial proteins can cause allergic sensitization. 

Follow the manufacturer’s instructions for cleaning / maintaining PPE. If no such instructions 

for washables exist, use detergent and hot water. Keep and wash PPE separately from other 

laundry. 

User Safety Recommendations: Users should remove clothing/PPE immediately if pesticide 

gets inside. Then wash thoroughly and put on clean clothing. Users should remove PPE 

immediately after handling this product. Wash the outside of gloves before removing. As soon 

as possible, wash thoroughly and change into clean clothing.

Environmental Hazards: Do not apply directly to water, or to areas where surface water is 

present, or to intertidal areas below the mean highwater mark. Do not contaminate water when 

disposing of equipment washwater or rinsate. 

DIRECTIONS FOR USE

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

any requirements specific to your State or Tribe, consult the agency responsible for pesticide 

regulation. 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.

Agricultural Use Requirements

Use this product only in accordance with its labeling and with the Worker Protection Standard, 

40 CFR Part 170. This Standard contains requirements for the protection of agricultural 

workers on farms, forests, nurseries and greenhouses, and handlers of agricultural pesticides. 

It contains requirements for training, decontamination, notification, and emergency assistance. 

It also contains specific instructions and exceptions pertaining to the statements on the label 

about personal protective equipment (PPE), and restricted entry interval (REI). The 

requirements in this box only apply to uses of this product that are covered by the Worker 

Protection Standard. 

Do not enter or allow worker entry into treated areas during the restricted entry interval (REI) of 

4 hours.

PPE required for early entry to treated areas that is permitted under the Worker Protection 

Standard and that involves contact with anything that has been treated, such as plants, soil or 

water is: coveralls, waterproof gloves, shoes plus socks.

Do not apply this product through any type of irrigation system.

General Information: BOTRY-Zen is a biological control agent developed specifically for the 

control of Botrytis cinerea and Sclerotinia sclerotiorum. 

BOTRY-Zen is a live spore preparation of a non-pathogenic saprophytic fungus. BOTRYZen acts as a biological control agent by competing for the same ecological niche as the 

plant pathogens Botrytis cinerea and Sclerotinia sclerotiorum.

When BOTRY-Zen spores are deposited on the dead and senescent plant debris, and the 

right environmental conditions exist, they germinate and colonize. The developed mycelium will 

proceed to colonize the dead tissue and, if conditions are suitable, additional sporulation can 

occur and these new spores are then available to colonize remaining debris. 

BOTRY-Zen aggressively occupies the same physical space and out competes Botrytis spp. 

and Sclerotinia spp. for the nutrients in the dead and senescing plant tissue; it is a true 

antagonist. BOTRY-Zen is non-invasive and causes no damage to live plant tissue. With this 

mechanism of action, it is highly unlikely that resistance to BOTRY-Zen will develop. 

Integrated Pest Management: Integrate BOTRY-Zen into an overall pest management 

strategy whenever fungicide use is necessary. Follow practices known to reduce disease 

development. Consult local agricultural authorities for specific IPM strategies developed for 

your crop(s) and location.

Pre-Harvest Interval: BOTRY-Zen can be applied up to and including the day of harvest, 

except as noted. See Application Rates table for crop-specific application frequency 

information. 

Mixing and Application Instructions: 

MIXING: Dilute BOTRY-Zen with water and apply in conventional spray equipment. Partially fill 

the spray tank with clean water and begin agitation. Add the specified amount of BOTRY-Zen 

to the tank. Finish filling the tank to the desired volume to obtain the proper spray 

concentration. Add a surfactant or a non-ionic adjuvant to improve product wetting / spreading. 

Maintain agitation continuously while spraying. Use spray mixture immediately. Do not allow 

spray mixture to stand overnight or for prolonged periods. 

APPLICATION: Apply BOTRY-Zen using conventional spray equipment to the point of 

saturation. Good coverage and wetting is required. The amount of spray solution to apply will 

vary depending on the type of crop. Most row crops will require up to 100 gallons of spray per 

acre. Apply in sufficient water to achieve thorough coverage.

COMPATIBILITY: Consult your BOTRY-Zen representative for more information on BOTRYZen compatibility with pesticides, surfactants and fertilizers. BOTRY-Zen may be tank 

mixed with some fungicides. Do not tank mix BOTRY-Zen with more than one product. 

Consult specific product labels for additional information or restrictions concerning tank mixing. 

Observe the most restrictive of the labeling limitations and precautions of all products used in 

mixtures. It is always advisable to conduct a spray compatibility test when you plan to mix this 

product with another product. To determine the physical compatibility of this product with other 
BOTRY-Zen; EPA Reg. No. (pending as File Symbol 75747-E)

MASTER LABEL - Label version (6) dated October 19, 2009

products, use a jar test. Using a quart jar, add the proportionate amounts of the products to 

approximately one quart of water with agitation. Add dry formulations first, then flowables, and 

then emulsifiable concentrates last. After thorough mixing, allow this mixture to stand for 5 

minutes. If the combination remains mixed or can be readily remixed, it is physically 

compatible. Once compatibility has been proven, use the same procedure for adding products 

to the spray tank.

BOTRY-Zen has been evaluated for phytotoxicity on a variety of crops under various normal 

growing conditions. However, testing all crop varieties, in all mixtures and combinations is not 

feasible. Prior to treating entire crop, test a small portion of the crop for sensitivity.
