Uses: Lactonfen is selective post-emergence herbicide, used to deal with stem and leaf. Limitly transmit through the plants after absorbed by the stem and leaves, it causes cell contents lossing by destriying the integrity of the membrance, finally the weeds die. Burn spots will appear on sensitive broad-leaved weed leaves, 2-3days after application, in adequate lighting conditions. The spots will expand until the whole leaf sear, then the weeds die.
