Fomesafen is a highly effective and selective herbicide. It is
mainly used for weeding after bean sprouts in bean fields. It has
special effects for controlling broad-leaved weeds. Its principle
of action is to absorb photosynthesis through the leaves and
destroy photosynthesis. The agent is also very active in the soil.
After the soybean seedlings 1 to 3 compound leaves, weeds 2 to 5
leaf stage, spray 25% water agent 9 to 20mL/100m2, spray the weed
stems and leaves to the water.
Pre-emergence application at this dose is better than pre-emergence application. The
disadvantage is that there will be some phytotoxicity to soybeans,
but it will recover quickly. It is not easy to cause phytotoxicity
to soybeans after pre-emergence application after sowing. Uses:
Mainly used to control quinoa, amaranth, Polygonum, nightshade,
thistle, sage, cocklebur, cocklebur, sesame, needle needle grass
and other weeds in soybean field. It is a highly effective
post-emergence herbicide for bean field, which can effectively
