Seed coating compositions for low temperature applications

摘要

A seed coating composition for low temperature applications, said seed coating composition comprising at least one polymer having a Tg of -60 DEG C to 20 DEG C, provided that the Tg of the polymer is less than or equal to the seed surface temperature at the time of application. The seed coating compositions of the invention provide a matrix which entraps active ingredients and improves seedling survival by maintaining the active ingredient on the surface of the seed for a period of time. The seed coating also increases the safety of using an active ingredient by reducing operator exposure and environmental release. In addition, the seed coating composition is resistant to cracking and flaking even when the seed coating composition is applied at a temperature of less than 20 DEG C. Moreover, the seed coating composition improves the uniformity of seed size and shape which is advantageous to mechanical planting techniques.
