General Information


ZOLONE FLO, containing phosalone insecticide, is recommended for the control of a wide range of insect pests in deciduous fruit orchards. Follow provincial recommendations for local variations of pest incidence and timing of sprays. Up to three applications of ZOLONE FLO may be made during the season. Use an efficient spray machine which will give thorough coverage of the trees.


KEEP OUT OF REACH OF CHILDREN. ZOLONE FLO contains an organo-phosphorus insecticide which may be harmful if swallowed or absorbed through the skin.

- During mixing, loading, cleanup and repair activities, wear long-sleeve shirt, long pants, shoes plus socks, and chemical-resistant gloves, and NIOSH-approved respiratory protection

- During airblast application

- Use a closed cab that provides both a physical barrier and respiratory protection (i.e dust/mist filtering and/or vapour/gas purification system) with other personal protective equipment (chemical-resistant coveralls, chemical-resistant gloves, chemical-resistant head gear and a respirator) immediately available for use in case of emergency (i.e., a broken package, spill, or equipment breakdown); or

- If a closed cab is not used, wear long pants, long-sleeved shirt, shoes plus socks, chemical-resistant gloves, chemical-resistant headgear, and chemical-resistant coveralls and NIOSH approved respiratory protection.

- All workers performing re-entry activities that involve significant contact with foliage or fruit must wear long pants, long-sleeved shirt, shoes plus socks and chemical-resistant gloves for critical post-application activities performed within 14 days of application.

During early re-entry, wash stations must be available for re-entry workers.

Double notification is required (i.e., written notice on posted signs and verbal notification to those re-entering the field) for field workers indicating that the area has been treated with phosalone and that phosalone is a cholinesterase inhibitor. This should include a brief description of the signs and symptoms of cholinesterase inhibition and ways to minimize exposure.

Do not enter, or allow worker entry into, treated areas during the restricted-entry interval (REI) of 14 days. Members of the general public involved in “pick your own”, “U-pick” or similar operations will not be permitted to enter a treated area for 30 days after application.

Wash with soap and water after use and before eating or smoking. Wash contaminated clothing thoroughly after use. Avoid working in spray mist. Do not contaminate water supplies (rivers, ponds, etc.). Avoid contamination of food or feed. ZOLONE FLO is classed as moderately toxic to bees and may be used around them if dosage, timing and method of application are correct. It should not be applied directly on bees whether in the field or at the colonies.


Apply only when the potential for drift to areas of human habitation or areas of human activity such as houses, cottages, schools and recreational areas is minimal. Take into consideration wind speed, wind direction, temperature, application equipment and sprayer settings.



ZOLONE FLO may be mixed in the spray tank with most horticultural products in common use; however, it must not be mixed with strongly alkaline materials such as Bordeaux mixture, lime sulphur, hydrated lime, etc. Apply all spray as soon as possible after mixing.


For resistance management, this is a Group 1B insecticide. Any insect population may contain individuals naturally resistant to this product and other Group 1B insecticides. The resistant biotypes may dominate the insect population if these insecticides are used repeatedly in the same field. Other resistance mechanisms that are not linked to site-of-action, but specific for individual chemicals, such as enhanced metabolism, may also exist. Appropriate resistance management strategies should be followed.

To delay insecticide resistance:

- Where possible, rotate the use of this product with different groups that control the same pests.

- Use tank-mixtures with insecticides from a different group when such use is permitted.

- Insecticide use should be based on an integrated pest management (IPM) program that includes scouting and record keeping and considers cultural, biological, and other chemical control practices;

- Monitor treated pest populations for resistance development.

- Contact the local extension specialist or certified crop advisors for any additional pesticide resistance-management and IPM recommendations for the specific site and pest problems in the area.
