DIFFERENTIAL TOLERANCE OF SUGARCANE CULTIVARS TO CLOMAZONE [PDF]

Planta Daninha, 2017
ABSTRACT Weed control is one of the most relevant costs of sugarcane production. If weeds are not controlled at the right time, the productivity and longevity of sugarcane plantations are reduced. In this crop, chemical control is the most used method, since it is efficient and it has a lower cost. Differentiated tolerance of sugarcane cultivars to the

Influence of Formulation on Mobility of Clomazone in Soil [PDF]

Bulletin of Environmental Contamination and Toxicology, 2016
The mobility of clomazone [2-(2-chlorobenzylo)-4,4-dimetylo-1,2-oxazolidin-3-one] in a loamy sand soil and a sand soil was studied in a soil column under laboratory conditions. Commercial clomazone formulation (Command 480 EC) and clomazone immobilized in an alginate matrix were used for a leaching experiment.
