Due to the ever growing concerns with the availability of water, many growers are moving more towards the use of drip and hydroponic irrigation systems and are using more recycled water. These operations can make growers more vulnerable to rapid crop losses due to the spread of water-borne plant pathogens in their facilities. OXINE can help growers prevent these losses.
There is a large volume of published data confirming the efficacy of chlorine dioxide solutions against the organisms of concern to the horticulture industry. D.A Slade, of Grower Consultancy Services in New Zealand regularly recommends OXINE™ to his hydroponics clients. Slade published the following tips for users:
“Disinfection Suggested Uses:
Use in Hydroponics Solutions: To control bacteria, Pythium, Phytophthora and other root rotting fungi, use between 0.5-2ppm activated with citric acid. Use a daily dose of 1-2ppm initially using the highest rate if algae are present. Reduce to 1.0-0.5ppm once free of algae and the root rot is under control. Continued use reduces algae levels. Avoid excessive rates of use. Check use on some varieties of Spinach and Phaeleonopsis. Minor white leaf spotting may occur on some varieties. Allow several days of gap if Copper spray is used to avoid formation of soluble copper.Foliage, shoots to prevent bacterial infection (Psa, BSR, Erwinia sp.) and spread within the crop; fungal Infections; bulb and tuber disinfection: Use frequent (as required by weather and presence bacteria, apply at 7 day maximum intervals until under control) as foliar sprays of 10ppm activated with citric acid. Add a listed surfactant to ensure adequate wetting. Important: Apply as a dilute spray to the point of run off.
Tubers & bulbs: Spray 5-10ppm plus a listed surfactant at lifting and after each handling. In cool stores use an atomized mist to control bacteria, yeast and Penicillium.
Flower Pulsing: 2 - 5ppm suggested. First, thoroughly disinfect buckets.
For control of foot and root rot fungi (e.g. Tomatoes) in bagged media: Use 5ppm, activated with phosphoric or citric acid, in the irrigation drip solution. Compatible with most nutrients after dilution.
Cleaning irrigation and Drip lines: Use 20ppm with a listed surfactant.
Soilless Media: For control of fungi in the media use as a drench at 10-20ppm. A bed drench of 50ppm is used to control bacteria in the mushroom industry. 100ppm rate is recommended as a pre-planting drench for soilless media where bacterial contamination is present and needs to be controlled. Add a listed surfactant.
Disinfection of Benches, Buckets, Equipment, Food Processing Lines: (No rinse required): Use 100pm of activated solution. Add a listed surfactant. Clean and remove all contamination from crop/food residues by flushing, brushing or scraping clean. Apply the solution as a fine spray to the surface of all equipment. Ensure that the equipment remains wet for at least one minute. Allow to air dry. Make up the activated solution daily. Never reuse.
These suggested uses are based on the best, currently available information. The results of use of the product are the responsibility of the user.”
