Embodiment example 1

[0036] Implementation case 1: Control effect of different combinations of glyphosate, glufosinate, and gibberellin on Mikania micrantha during vigorous growth

[0037] 41% glyphosate isopropylamine saline solution, 20% glufosinate-ammonium water solution and 40% gibberellin water-soluble granule were formulated into different herbicide medicaments respectively according to the formula in Table 1, and then watered to 600-675L. The treatment group 1 with clear water was used as the control group (see Table 1).

[0038] Select the thicker branches of Mikania micrantha in the current year and cut every 2 nodes into one section, and plant them in flowerpots with a diameter of 11.5cm x a height of 10cm, one plant per pot, when the stem length of the Mikania micrantha plant is 130-150cm (that is, the vigorous growth period) time for testing.

[0039] Use the spray method. Use a quantitative sprayer to evenly spray the stems and leaves of Mikania micrantha, and the spray volume is 6...

Abstract

The invention discloses a gibberellin-containing medicament for preventing and removing mikania micrantha and application of the gibberellin-containing medicament, and relates to the field of invasiveplant prevention and control. The effective components in the medicament are glyphosate, glufosinate-ammonium and gibberellin; wherein the mass ratio of the glyphosate to the glufosinate-ammonium tothe gibberellin is 100:55:(1.125-9). According to the invention, by means of the physiological regulation effect of gibberellin on plants, compared with the prior art, the glyphosate and glufosinate-ammonium compounded herbicide has the advantages that the conductivity of the herbicides glyphosate and glufosinate-ammonium in plants is improved, so that the compounding of glyphosate and glufosinate-ammonium has an obvious synergistic effect, and the use amount and spraying times of the herbicides are reduced; a reliable guarantee is provided for effectively removing mikania micrantha in a large-area mikania micrantha invasion field, and good economic and ecological benefits. The medicament is simple and convenient to use, is suitable for large-area popularization and application in mikaniamicrantha invaded places, accelerates prevention and removal of mikania micrantha, and promotes recovery and healthy development of ecosystems of the invaded places.

Description

technical field [0001] The invention relates to the field of prevention and control of invasive plants, in particular to a gibberellin-containing medicament for preventing and controlling Mikania micrantha and its application, in particular to a combination of glyphosate, glufosinate-ammonium and gibberellin to improve the effect of preventing and controlling mikania micrantha and reduce the use of herbicides. Background technique [0002] Mikania micrantha Kunth (Mikania micrantha Kunth), also known as Eupatorium micrantha or Eupatorium chrysanthemum, is a perennial herbaceous vine of the genus Eupatorium in the Asteraceae family. It is native to Central and South America and has been widely spread to tropical Asia. , one of the most destructive weeds. Mikania micrantha likes fertile and moist soil, and it is easier to grow under sufficient light conditions. It competes for sunlight by climbing, entwining, and covering adjacent plants, and consumes a large amount of water ...
