Imazapyr is a non-selective herbicide used for the control of a broad range of weeds including terrestrial annual and perennial grasses and broadleaved herbs, woody species, and riparian and emergent aquatic species. It is used to eliminate Lithocarpus densiflorus (Tan Oak) and Arbutus menziesii (Pacific Madrone).
Additionally, imazapyr is used to control annual and perennial grass and broadleaved weeds, brush, vines and many deciduous trees. Imazapyr is absorbed by the leaves and roots, and moves rapidly through the plant. It accumulates in the meristem region (active growth region) of the plant. In plants, imazapyr disrupts protein synthesis and interferes with cell growth and DNA synthesis.
As a kind of non selective herbicide, it can quickly be absorbed by the roots and leaves of weeds, and prevent the growth of weeds by inhibiting the biosynthesis of branched chain amino acids. It is a kind of herbicide. It is longer in the soil. It is suitable for the crops of forest land, farmland. It can prevent most annual and perennial, dicotyledonous weeds.
Imazapyr acid is a kind of organic heterocyclic herbicides and the isopropylamine salt can bud or bud, can be quickly absorbed by the roots and leaves of plants, inhibit plant side chain amino acid biosynthesis, inhibit the growth of weeds, promoting the death. Control object including all the weeds and have good herbicidal activity of Cyperaceae weeds, annual and perennial monocotyledonous weeds and broad-leaved weeds and miscellaneous. Applicable to non cultivated land and rubber plantations, oil palm, forest and tea garden.
It can be used before and after bud. Weeding in the non cultivated land, it amounts to 0.25 ~ 2.5kg (AI) / hm2; in rubber and oil palm garden, dosage of 0.125 ~ 1.0kg (AI) / hm2; in the forest, dosage of 0.25 ~ 1.25Kg (AI) / hm2; in the tea garden, dosage of 0.1 ~ 2.0kg (AI) / hm2; in addition, the coated or injection inactivated tobacco can prevent the germination of deciduous tree stumps.
In the soil, the length of the residual effect is 8 years.
In 45 DEG C, destroy tobacco can be stable for 3 months, at room temperature, steady for two years. In the pH5 ~ 9, the dark, water medium, it is stable and storage can not be higher than 45 degrees. The product solution was decomposed in simulated sunlight, DT506 days (pH5 to 9), DT5090 to 120 days in soil. Can't be mixed or stored in a non liner container, because of its corrosive nature. Reaction with alkali or acid and strong oxidizing agents.
Appearance: white crystal powder
Packing: 25KG drum
