Methylated Seed Oil (MSO) Adjuvant
CAS Number: 61788-61-2
Methylated seed oil (MSO) is a crop oil concentrate adjuvant derived from the transesterification of vegetable oils, primarily soybean or canola oil. It significantly enhances herbicide absorption through the leaf cuticle by acting as a penetrant and humectant. MSO is widely used with post-emergent herbicides such as glyphosate, nicosulfuron, and graminicides to boost field efficacy.
