Plant growth regulators are used mid- and late-season and play a crucial role in final yield output. In general, PGR applications from the matchhead square to early-bloom growth stages modify plant growth to direct energy toward better boll development. Late-season PGRs focus on priming the plant for a quality harvest through defoliant, boll opener, and/or desiccant activity.
Super Boll plant regulator hastens the opening of mature cotton bolls, enabling growers to harvest earlier and increase recoverable yield.
Mepex is a foliar-applied plant growth regulator which modifies the cotton plant allowing the management of short-season production with reduced risk of yield and quality loss due to delayed and prolonged harvest. Mepex reduces plant height, offers better boll retention, and helps improve defoliation for reduced trash and better harvest efficiency.
Gin Out PGR goes beyond proven regulation with its unique mepiquat chloride + kinetin combo. Kinetin, a cytokinin plant hormone, plays a natural role in plant growth and health, especially during times of temperature or water stress. Gin Out works in several specific ways to strengthen root systems, promote earliness, and aid proper boll set – raising lint yield.
• Synthesis and accumulation of chlorophyll
• Leaf expansion
• Cell division and lateral bud growth
• Stomata opening and transpiration rate (improving response to water stress)
• Leaf senescence (particularly subtending bracts which drive boll development)
• Wilting (by alleviating negative effects of water stress)
Late-season PGRs prime cotton crops to maximize harvest quality. They synchronize boll maturation, leaf drop and plant desiccation to optimize harvest conditions – all while reducing the days-to-harvest timeline.
CottonQuik® accelerates the opening of mature bolls and minimizes regrowth for a clean harvest – even in cool weather (boll opener)
