Use

Fomesafen can be used as an efficient and selective herbicide. It is mainly used for post-emergence weeding in soybean fields and has special effects on controlling broadleaf weeds. Its principle of action is to absorb through leaves and destroy photosynthesis. The agent is also very active in the soil. When soybeans have 1 to 3 compound leaves after emergence and weeds have 2 to 5 leaves, use 25% aqueous agent 9 to 20 mL/100m2 to spray the weed stems and leaves with water. At this dose, pre-emergence application is better than pre-sowing application. The disadvantage is that it will cause certain phytotoxicity to soybeans, but it will recover quickly. Post-sowing and pre-emergence application is less likely to cause phytotoxicity to soybeans.

Purpose

Mainly used in soybean fields to control weeds such as pigweed, amaranth, polygonum, nightshade, thistle, duck's toe, cocklebur, hemp, and ghostweed.
