Bayer’s second US spirotetramat approval
Bayer CropScience has received US approval for a second formulation of its new insecticide, spirotetramat. Ultor (spirotetramat 150 g/litre) is a suspension concentrate (SC) formulation for use on pome fruit, hops and Christmas trees. The company received US approval for a 240 g/litre SC formulation, Movento, for use on a wider range of crops last year ( Agrow No 547, p 19). Ultor is recommended for use at 8-16 fl oz/acre (0.6-1.2 litres/ha) against aphids, mealybugs, scales and psylla.
