Abstract

Narrow bands of activated charcoal sprayed on the soil surface directly over the rows seeded with alfalfa (Medicago sativa L., var. Cayuga) in the field protected the legume from damage by a broadcast application of 2-isopropylamino-4-(3-methoxypropylamino)-6-methylthio-s-triazine (hereafter referred to as G-36393). Charcoal suspended in water and applied at 25 to 50 lb/A, gave adequate protection from 1.5 lb/A G-36393. Higher rates of charcoal, 100 lb/A, were necessary to protect the legume from a 3.0 lb/A application. Charcoal did not protect alfalfa seedlings from 1.5 lb/A 2-chloro-4-ethylamino-6-isopropylamino-s-triazine (atrazine).
