Abstract

Seed rice was treated with 0.25% methiocarb to test its effectiveness as a blackbird repellent in Vermilion Parish, Louisiana in the spring of 1975. Two replications of 3 treated and 3 untreated plots showed 68% more seedlings in treated plots (2,393) than in untreated plots (1,429). Half as many birds (chiefly redwing blackbirds (Agelaius phoeniceus) were recorded in treated (1.18/mi n) as in untreated plots (2.39/min).
