| Applications | Uses: Used as plant growth regulator to promote ripening in fruits, nuts, and other crops and to stimulate latex flow in rubber, [HSDB] Used primarily on cotton, [Reference #1], Farming (Pesticides) [Category: Industry], For ethephon (USEPA, OPP Pesticide Code: 099801) ACTIVE products with label matches., SRP: Registered for use in the U.S. but approved pesticide uses may change periodically and so federal, state and local authorities must be consulted for currently approved uses., A plant-growth regulator that increases rate of ripening of plants by promoting release of ethylene, stimulates rubber latex formation, ripening of sugarcane, flowering agent for pineapple, color enhancer., In cotton, it is used as a boll opener and defoliant prior to harvesting., Ethephon is used to promote fruit ripening, abscission, flower induction, breaking of apical dominance (inhibition of the growth of lateral buds by the terminal bud of a shoot), and other plant responses., This is a man-made compound that is used as a pesticide., Use Classification: Environmental transformation -> Pesticides (parent, predecessor), Plant growth regulators, Methods of Manufacturing: CLEAVAGE OF THE BIS(2-CHLOROETHYL) ESTER OF 2-CHLOROETHYL PHOSPHONIC ACID, Ethephon is made from tris(2-chloroethyl) phosphite by rearrangement to bis(2-chloroethyl)2-chloroethyl phosphonate followed by hydrolysis, Formulations, Preparations: Aqueous solutions, liquid concentrate., Premix Partners: AMADS, chlormequat chloride, cyclanilide, mepiquat chloride., Emulsifiable concentrate, suspension concentrate (flowable concentrate), soluble concentrate., First Pick Cotton Harvest Aid, Defoliant (Nufarm Americas Inc): Ethephon 18.3%, Sulfuric acid, monourea adduct 58.6%., For more Formulations, Preparations (Complete) data for ETHEPHON (44 total), please visit the HSDB record page., Consumption Patterns: On average about 4.1 million pounds of ethephon are used annually on 1.7 million acres. The crops with highest percent crop treated are tart cherries (61%), grapes (40%), processed tomatoes (15%), and cotton (10%)., U.S. Production: (1972) PROBABLY GREATER THAN 4.54X10+5 GRAMS, (1975) PROBABLY GREATER THAN 4.54X10+5 GRAMS, General Manufacturing Information: The WHO Recommended Classification of Pesticides by Hazard identifies ethephon (technical grade) as Class III: slightly hazardous, Main Use: plant growth regulator., ETHEPHON SPRAY ON TOMATO TRANSPLANTS (LYCOPERSICON ESCULENTUM) 12 DAYS PRIOR TO PULLING RESULTED IN PARTIAL PROTECTION OF THE PLANTS FROM FROST INJURY AFTER TRANSPLANTING., ... Ethephon is an organophosphonate as opposed to an organophosphate. It is structurally different from and exhibits different physical, chemical properties than traditional organophosphate compounds. The toxicological profile of ethephon also differs from that of the organophosphate compounds. |
