General Instructions


Ovasyn Options must always be mixed with the registered rate of a compatible larvicide. The product may be used either in water based low volume, or ultra low volume (ULV) application.


Export of treated produce

Growers should note that MRL's or import tolerances do not exist in all markets for produce treated with Ovasyn Options. If you are growing produce for export, please check with Arysta Lifescience Corporation for the latest information on MRL's and import tolerances BEFORE using Ovasyn Options.




Applied with water: Part fill the spray tank with water and then, with the agitator running, add the Ovasyn Options. Add the compatible larvicide and complete filling the tank. Use prepared spray mixture immediately.DO NOT allow to stand overnight.


Applied ULV: Fill the required volume of Ovasyn Options directly into aircraft hopper or mix vat and with agitation operating add the required volume of a compatible larvicide. Use the prepared spray immediately.DO NOT allow to stand overnight. DO NOT add water. In ULV mixtures, it is essential that no water be present in the spray sytem.


Applicaion and Equipment


Accurate placement and good foliar coverage are essential. Note: Insect control could be diminished if rain falls within 6 hours of application. When mixed with Thiodan® EC ensure that all Thiodan label recommendations are strictly adherd to.


Ground spray

Standard low volume boom or high volume equipment may be used.  Apply in a minimum total volume of 80 L/ha.



Applied with water - Ovasyn Options may be applied by aircraft using water as a carrier. Apply in a minimum total volume of 20 L/ha.


Applied ULV - Ovasyn Options may also be used without dilution in mixture with some ULV products as listed under 'Compatibility'. A minimum total spray volume of 3.0 L/ha should be applied ULV. For example, where the mixing partner is Decis Options® the addition of DC Tron® Cotton Spray Oil as a bulking agent will be required.


Ovasyn Options Insecticide must only be applied by aircraft fitted with accurately calibrated ULV equipment, eg. Micronair AU5000 atomisers. To minimise drift it is esential to produce a suitable spray droplet diameter (volume mean diameter) by controlling the rotational speed of the atomisers. It is recommended that the application parameters in terms of plane speed and blade angle settings are adjusted to deliver a maximum rotational speed of 3000 rpm and a resultant droplet diameter of approximately 100 microns. Rotational speed of the atomisers can be measured by the fitment and maintenance of transducers.




Applied with water

This product is compatible with Affirm, Curacron 500 EC, Decis Options, Dipel, Folimat 800, Gemstar, Intrepid, Larvin 375 SC, Mustang, Predator, Reign®StewardTMTalstar 100 EC, Thiodan EC and Tracer II. Combinations with Larvin 375 SC should be used within 6 hours of mixing.


Applied ULV

This product is compatible with Curacron ULV, Decis Options & Decis Forte ULV, methyl parathion, Predator, Ampol Green and DC Tron Cotton.


Insecticide Resistance Warning


For insecticide resistance management, Ovasyn Options insecticide is a Group 19A insecticide. Some naturally occurring insect biotypes resistant to Ovasyn Options and other Group 19A insecticides may exist through normal genetic variability in any insect population. The resistant individuals can eventually dominate the insect population if Ovasyn Options or other Group 19A insecticides are used repeatedly. The effectiveness of Ovasyn Options on resistant individuals could be significantly reduced. Since occurrence of resistant individuals is difficult to detect prior to use, Arysta Lifescience Corporation accepts no liability for any losses that may result from the failure of Ovasyn Options to control resistant insects. The user should seek advice, and monitor the performance, and if the results are not in accordance with expectations, contact the manufacturer immediately. Apparent resistance however, should not be confused with poor application, coverage or timing techniques. Ovasyn Options may be subject to specific resistance management strategies. For further information contact your local supplier, Arysta Lifescience representative or local agricultural department agronomist.




Re-Entry Period

Do not allow entry into treated areas until the spray deposits have dried. When prior entry is necessarywear cotton overalls buttoned to the neck and wrist and elbow-length PVC gloves. Clothing must be laundered after each day's use. 


Drift Warning

DO NOT apply under weather conditions, or from spraying equipment that could be expected to cause spray to drift onto adjacent crops, crop lands, pasture or livestock.


Protection of wildlife, fish, crustaceans and environment

DO NOT contaminate streams, rivers or waterways with the chemical or used containers. Toxic to fish. The empty container must not be reused for any other purpose.


Safety Directions


May irritate the eyes and skin. Avoid contact with eyes and skin. Do not inhale spray mist. When preparing spray or using prepared spray, wear cotton overalls buttoned to the neck and wrist, washable hat, elbow-length PVC gloes and face shield. If product on skin, immediately wash area with soap and water. After use and before eating, drinking or smoking, wash hands, arms and face thoroughly with soap and water. After each day's use, wash gloves, face shield and contaminated clothing.



Store in the closed, original container in a dry, cool, well-ventilated area out of direct sunlight. Immediately and thoroughly close part-used containers to avoid deterioration of product.



Triple or preferably pressure rinse containers before disposal. Add rinsings to spray tank. Do not dispose of undiluted chemicals on site. If recycling, replace cap and return clean containers to recycler or designated collection point. If not recycling, break, crush or puncture and bury empty containers in a local authority landfill. If no landfill is available, bury the containers below 500 mm in a disposal pit specifically marked and set up for this purpose clear of waterways, desirable vegetation and tree roots. Empty containers and product should not be burnt.
