Research

Use of crop inputs, including prophylactic application of insecticides, has increased in soybean production. A liquid fertilizer-ready formulation of bifenthrin was recently labeled for in-furrow use with a starter fertilizer on soybean. An experiment was conducted at 6 sites (3 in Minnesota and 3 in Ohio) in 2013 and 2 sites (in Minnesota) in 2014 to evaluate effects on soybean of prophylactic in-furrow applications of a liquid fertilizer-ready insecticide (bifenthrin) and a 2-6-16 (N-P-K) liquid starter fertilizer alone and in combination.
