WebCypermethrin is subject to photodegradation and microbial degradation under aerobic conditions. Cypermethrin binds strongly to soil particles and poses minimal leaching concerns. Cypermethrin hydrolyzes slowly under acidic or neutral conditions but more rapidly under alkaline conditions. WebCritical GAP for cypermethrin on pomelos in Thailand is for four foliar spray applications at 12 g ai/hl at a 7-day interval and PHI 14 days. In trials from Thailand (4× 9.4 g hL, PHI 14 days) matching this GAP cypermethrin (sum of isomers) residues in pomelo whole fruit were 0.11, 0.11, 0.14, 0.16, 0.18 and 0.25 mg/kg (n = 6). grand mercure harmoni ballroom
