Phytotoxicity of Triphenyl Tin Acetate to Rice Seed

Abstract

During experiments in Swaziland rice paddies, it was shown that aerial application of triphenyl tin acetate at a rate of 1 lb. a.i. per acre resulted in good control of the snail Lanistes ovum, a destructive pest of rice seedlings (Crossland 1964). However, rice seed sown immediately and at 24 and 48 hours after treatment gave rise to stunted and etiolated seedlings, suggesting phytotoxicity.
