Mepex is a foliar applied plant growth regulator which modifies the cotton plant allowing the management of short-season production leading to 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 which can lead to reduced trash and better harvest efficiency.
