Abstract:Herbicides Metribuzin [4-amino-6-tert-butyl-3-(methylthio )-as-triazin-5-(4H)one] at 0.8 and 1.6 kg/ha active ingredient, Prometryn [2,4-bis (isopropylamino)- 6-(methylthio)-s-triazine] at 3.3 and 6.6 kg, and Chloramben [3- amino-2,5-dichlorobenzoic acid] at 3.3 and 6.6 kg/ ha were evaluated for preemergence weed control on pigeon peas during 1976 at Lajas, Puerto Rico, in a Vertisol soil. The yield with Metribuzin at 0.8 kg/ha a.i. was similar (P=0.01) to that of the hand-weeded treatment. No statistical diff… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
