|For accelerated boll opening, defoliation and pre-conditioning before defoliation of cotton.
Chemical Group phosphonic acid derv
A foliar spray with Ethephon will accelerate opening of mature bolls and enhance defoliation, which can result in earlier harvest and increased recoverable yield and quality.
Some premature drop of small immature bolls may occur. Harvest at optimum boll opening and optimum defoliation. Too late harvest may reduce quality and lint.
Do not mix with desiccants containing sodium chlorate as this could result in emission of toxic chlorine fumes. Ospray Ethephon may be tank-mixed with defoliant products. Since the formulations of other products are beyond the control of Ospray, tank mixtures should be tested before commercial use.
Half fill spray tank with water, add the required amount of product, then remainder of water and mix well. Do not use alkaline water
Do not apply before sufficient mature unopened bolls have developed to product the desired yield of cotton. Bolls are mature when the seed coat turns light brown, the embryo fills the seed cavity with an abundance of creamy colour and cotyledons are well defined.
Light canopy: apply Ospray Ethephon, then apply defoliant 4-7 days later. Moderate to Heavy canopy: first apply a pre-conditioner, then apply Ospray Ethephon as soon as sufficient leaves have dropped to expose target bolls, usually 4-10 days later.
Apply by placement techniques as follows to achieve a target droplet density of 60 droplets per sq. cm.
Wind direction - Cross wind
Wind speed - 6-20 kph
Air temperature - Max. 32 deg C
Delta t - Max. 10 deg C
Ethephon is corrosive to metals. Mix only the quantity of spray required for immediate use and do not allow to stand in metal containers for more than 2 hours. Flush equipment thoroughly with water after use.
Do not apply if rain is expected within 8 hours.
Do not apply if daytime temperature is below 18C.
Do not apply if cotton bolls have been burned by frost.
Do not pretreat with a desiccant (chlorate) before using Ospray Ethephon.
Protection of wildlife, fish, crustaceans and environment
Dangerous to fish. Do not contaminate streams, rivers or waterways with the chemical or used container.
Protection of crop, native and other non-target plants
Do not apply under meteorological conditions or from spraying equipment which could be expected to cause spray to drift onto nearby susceptible plants/crops, cropping lands or pastures.
Product is harmful if swallowed. Attacks eyes and repeated minor exposure may have a cumulative poisoning effect. Obtain an emergency supply of Atropine tablets 0.6mg.
Protect eyes while using. When preparing spray and using the prepared spray wear elbow length PVC gloves and face shield or goggles. Wash hands after use. After each day's use, wash gloves and face shield or goggles and contaminated clothing.
Store in the closed original container in a cool, well ventilated area. Do not store for prolonged periods in direct sunlight.
Triple or preferably pressure rinse containers before disposal. Add rinsings to spray tank. Do not dispose of undiluted chemical on site. If recycling, replace cap and return clean containers to recycler or designated collection point. If not recycling, break, crush, puncture and bury empty containers in a local authority landfill. If not available bury the containers below 500mm in a disposal pit specifically marked and set up for this purpose clear of waterways, desirable vegetation and roots. Empty containers and product should not be burnt.
For refillable containers, empty contents fully into application equipment. Close all valves and return to point of supply for refill or storage.
