The label expansion is
welcome news for blueberry growers as it provides them with an effective tool
to control competitive weeds.

Callisto owes its
origins to the discovery of a natural compound exuded from the Callistemon
plant that provides it with a defense against other competing vegetation. This
compound provided the chemical foundation to build mesotrione, the active
ingredient in Callisto 480SC.

In highbush and lowbush
blueberries, Callisto 480SC can be applied up to the eight-leaf stage of weeds
prior to crop bloom at a rate of 0.12L/ac. This herbicide provides control of
lamb’s-quarters, redroot pigweed, velvetleaf, wild mustard, eastern black
nightshade as well as suppression of common ragweed.
