How to choose a post-emergence herbicide specifically for yam fields?

Yam, long known as “the medicine of the mountains and the medicine of foods”, is one of the earliest plants eaten by humans. It is rich in nutrients, nourishes and strengthens the body, and beautifies the complexion, making it a rare healthy and nutritious food. But in the process of growing yam, there are always many weeds. So today I will introduce several post-emergence herbicides specifically for yam fields.

A commonly used post-emergence herbicide for yam is quizalofop-p-ethyl, applied after true leaves appear. This product has low residue and degrades quickly in soil, but it only controls grass weeds and has little effect on broadleaf weeds. We can choose a herbicide specifically for yam

Post-emergence herbicides specifically for yam fields include: Hekuotong, which controls both pointed-leaf and round-leaf weeds, one box with one barrel of water for half a mu of land, a herbicide mixture; quizalofop-p-ethyl - a post-emergence herbicide specifically for yam fields, active ingredient: 100 grams per kilogram, formulation: emulsifiable concentrate; a post-emergence 1+1+1 herbicide specifically for yam fields. It is a current post-emergence stem-and-leaf herbicide for yam fields and is effective against all weeds in yam fields.

In addition, you must know that no matter which yam herbicide is used, it must be applied before the weeds sprout or just as they sprout. At this time the effect is best, and weed control is more assured. Prometryn is prohibited on sandy soil to avoid phytotoxicity. When spraying, precautions such as the spraying concentration must strictly follow the instructions, otherwise it may cause phytotoxicity to the soil or to the person applying the pesticide.
