PERpose Plus by BioWorks
PERpose Plus


PERpose Plus is a Hydrogen Peroxide (Hydrogen Dioxide) based, OMRI Listed broad spectrum algaecide and fungicide . It works by oxidizing the outer cell membrane of vegetative endospore, fungus and algae, and yeast and mold spore cells. The vast amount of oxygen released in this process helps relieve anaerobic conditions. In addition to the hydrogen peroxide, this proprietary formula contains stabilizers and buffers that counteract phytotoxicity allowing you to use PERpose Plus freely all over plant material and into the root zone without fear of damaging delicate plants. Similar products on the market contain peroxyacetic acid, which may cause damage (especially with continued use) to flower bracts and plant tissue. These peractic acid products can also produce a strong odor, which can be quite intense when growing inside. With odor-free PERpose Plus , your treatment won't run you out of your greenhouse. As a treatment for the suppression, prevention and control of fungus and algae, you can apply this to any part of the plant, in chemigation/fertigation systems or on hard non-porous surfaces like cooling towers, walkways, tools, ventilation equipment, watering systems, storage buildings, benches and more. Biodegradable PERpose Plus works on contact and provides cost effective, dependable and earth friendly control.

Warning & Toxicities:

This pesticide is toxic to birds, mammals, fish and aquatic life. Do not discharge effluent containing this product into lakes, streams, ponds, estuaries, oceans or other waters unless in accordance with requirements of a National Pollutant Discharge Elimination System (NPDES) and the permitting authority has been notified in writing prior to discharge. Do not discharge effluent containing this product to sewer systems without previously notifying the local sewage treatment plant authority. For guidance contact your State Water Board or Regional Office of the EPA. This product is highly toxic to bees and other beneficial insects exposed to direct contact in blooming crops or weeds. Do not apply this product or allow it to drift to blooming crops or weeds while bees are actively visiting the treatment area. Do not apply this product or allow it to drift to crops where beneficial insects are part of an Integrated Pest Management strategy.

  • PERpose Plus is a strong oxidizing agent. Mix only with water. PERpose Plus is not combustible; however, at temperatures exceeding 156°F, decomposition releases oxygen. The oxygen released could initiate or promote combustion of other materials.
  • Corrosive as a concentrate. Causes irreversible eye damage and skin burns. Harmful if swallowed. PERpose Plus may be fatal if absorbed through the skin. Do not get in eyes, on skin or clothing. Do not breathe vapor from concentrate. Wear protective eyewear, long sleeved shirt and long pants and chemical resistant footwear and gloves. Wash thoroughly with soap and water after handling and before eating, drinking or using tobacco. Remove contaminated clothing and wash before reuse.


Shelf Life: PERpose Plus will only lose about 1/3 of 1% of the original efficacy per year when stored as directed. It will remain effective as long as there is nothing for it to react with. It is important to keep the container closed and stock tank solutions covered. Freezing will not have an effect on PERpose Plus concentrate; however, it will begin to break down at temperatures at or above 86°F.

Use & Instructions


PERpose Plus can be applied via foliar spray, drench applications, chemigation, flooded floors, mist, fogging applications and drip irrigation systems. It is advisable to test a small sample of PERpose Plus on plants prior to treating large numbers, as not all plant species have been tested. PERpose Plus works best when diluted with water containing low levels of organic or inorganic materials and having a neutral PH. The Restricted Entry Interval (REI) is 0 hours for most applications; however, interior fogging and spraying applications of PERpose Plus have an REI of 1 hour. For field applications, do not allow re-entry until sprays have dried. It is not advisable to apply in dry and/or extremely hot conditions.

Do not reuse already mixed solution; make fresh daily.

Product Compatibility: PERpose Plus concentrate must not be combined with or mixed with any other pesticide or fertilizer concentrates. A diluted solution may be used in combination with most soluble fertilizers, although a compatibility test should be completed prior to mixing a final batch. It is not compatible with products that have the following active ingredients: magnesium/copper, magnesium/zinc, copper and aluminum. For best results, apply PERpose Plus solution and let dry before applying the chemical in question or contact manufacturer for a compatibility product list.


Application Rate: The rates listed for application of PERpose Plus are universal for both agriculture and horticulture use. The rates for curative results are 1:100, or roughly 1 fl. oz. per gallon of clean water and 1/4-1/3 fl. oz. per gallon of clean water as a weekly preventative rate.

Environment: Commercial greenhouses, garden centers, nurseries, professional turf care, interiorscapes, orchards, field crops, vineyards, groves, theme parks, zoos and landscapes.

Storage: Do not contaminate water, food or feed by storage or disposal. Store in the original container in a cool area out of direct sunlight and away from combustibles.
