Used in non-crop areas, such as industrial sites, railways, roads, drainage channels, etc., at 0.25-1.7 kg/ha; in forestry management, at 0.25-1.7 kg/ha; and in plantations of rubber trees and oil palms, at 0.125-1.0 kg/ha. Phytotoxicity Non-phytotoxic to conifers. Rubber trees and oil palms show good tolerance, though application onto foliage is not selective, and care should be taken to avoid contact of the spray with the foliage of oil palms and the leaves and young bark of rubber trees.
