US to OK salicylic acid seed treatments
The US EPA proposes to register two salicylic acid-based seed treatments from the US company, Loveland Products (Greeley, Colorado). Salicylic acid is a naturally occurring plant hormone that induces systemic acquired resistance to plant pathogens when applied to seed, the EPA notes. Loveland’s LPI 6194 Concentrate (salicylic acid 0.04% + indole-3-butyric acid 0.02% + chitosan 1%) is for use only by commercial seed treatment facilities and LPI 6194 RTU (salicylic acid 0.0067% + indole-3-butyric acid 0.0033% + chitosan 0.17%) is for on-farm use. Both products are for use on a range of arable crops, vegetables and ornamentals. The EPA posted the registration application in February 2011 ( Agrow No 609, p 22). Its approval decision is open to public comment until February 19th.
