Balsamrose can be killed with glyphosate herbicide.

Glyphosate is a non-selective, non-residual inactivating herbicide, which is very effective on perennial root weeds and is widely used in rubber, mulberry, tea, orchards and sugarcane fields. It mainly inhibits the enolpyruvyl mangiferin phosphate synthase in plants, thus inhibiting the conversion of mangiferin to phenylalanine, tyrosine and tryptophan, which interferes with protein synthesis and leads to plant death.

Glyphosate is absorbed through the stem and leaves and then conducted to all parts of the plant, and can prevent and eliminate plants of more than 40 families, including monocotyledons and dicotyledons, annuals and perennials, herbs and shrubs. Glyphosate quickly combines with metal ions such as iron and aluminum after entering the soil and becomes inactive.

It was initially used in rubber plantations to prevent thatch and other weeds, which can make rubber trees cut rubber 1 year earlier and increase the yield of old rubber trees. Now it is gradually promoted in forestry, orchard, mulberry garden, tea garden, rice and wheat, rice and oilseed rape crop rotation. Various weeds have different sensitivity to glyphosate, and thus the dosage is different.

Such as barnyard grass, dogweed, look at the maidenhair, oxalis, Matang, Pig Calamity and other annual weeds, the dosage of the active ingredient is 6-10.5g/100m2, the dosage of the effective ingredient for the plantain, small fleabane, duckweed, etc. 11.4-15g/100m2, and the dosage of the active ingredient for the white fescue, sclerophyllum, reeds and so on, 18-30g/100m2, generally 3-4.5kg, to the weeds, the amount of glyphosate, the dosage of the effective ingredient for the weeds.

Generally speaking, it is a good idea to spray the weed stems and leaves with water (3~4.5kg).

General broadleaf weeds in the early budding or flowering stage, grass in the late nodulation or early spiking per mu dosage of 20-30 kg of water spray. The plants that have been cut off the stems and leaves should wait until the weeds have enough new leaves before applying the drug. When preventing perennial weeds, a single dose of medicine divided into two times, the interval of 5 days can improve the effectiveness of prevention.

The growth environment of the balsam fern

The balsam fern is an angiosperm family Salixaceae Salix spp. The stem is slightly thin, the base tuberous; the leaves are slightly more, spreading, brown; the flower spikelet is obliquely spreading, linear, the rachis of the spikelet is a broad white transparent wing, ovate or oblong-ovate, the middle is green, the two sides of the purplish or reddish-brown; the style is elongated and trigonous. Fruiting scales slightly densely imbricate. Fruit scales are slightly densely imbricate. Aromatic epimedium is a perennial herb in the family of Salviaceae, and the whole plant has a special fragrance, hence its name.

The plant is native to Africa, South Asia and Europe, and now grows in tropical to temperate regions of Asia, Australia and the Americas, where it is found in wastelands, roadsides, ditches, or sunny places in the fields, and it is also common in sandy areas along the seashore. Balsam ferns are propagated by roots and seeds.
