Description
Technical Field
The invention relates to the technical field of weed prevention and control, in particular to a mikania micrantha prevention and control medicament and a mikania micrantha prevention and control method.
Background
Mikania micrantha (Mikania micrantha Kunth), also known as Eupatorium minor or Eupatorium pseudochinensis, is a perennial herb or shrub climbing vine of the Compositae family. Native to south and central america, has now spread widely to tropical and subtropical asia regions, and is one of the most harmful weeds in the world today. The mikania micrantha can propagate through seeds and can also propagate asexually, the mikania micrantha climbs and winds on arbor and shrub plants in a suitable place and is heavily pressed on the top of the canopy layer of the mikania micrantha, the photosynthesis of the attached main plants is blocked, the attached main plants die, the mikania micrantha grows rapidly and is not shade-tolerant, the attached main plants are wound and covered through climbing, the huge influence is caused on forests and farmland lands, in addition, the mikania micrantha can release chemical substances and inhibit the growth of other plants, the species is single, and the diversity of organisms is damaged. Due to the rapid growth of mikania micrantha, stem nodes can root and propagate at any time, the habitat is rapidly covered, the mikania micrantha has rich seeds and can invade rapidly, the growth of natural vegetation and crops is inhibited through competition or other sensibility, and the mikania micrantha is one of the most dangerous harmful plants in the world.
Nowadays, main prevention and control methods of mikania micrantha are divided into physical prevention and control, chemical prevention and control and biological prevention and control. The physical method refers to manual removal, namely manual removal or cutting off of overground parts by tools such as a knife, a shovel and the like, and a direct burning mode and the like, is suitable for the scattered-growing type emergence places of the mikania micrantha and places which are not suitable for herbicide removal, such as vegetable garden places, nursery places, orchards and the like, and has high cost and uncertain effect. The chemical prevention and control means that the mikania micrantha is sprayed by a chemical herbicide, commonly used medicaments for preventing and controlling the mikania micrantha comprise puremide, glyphosate, phenoxy carboxylic acid herbicides, sulfonylurea herbicides and the like, and the spraying of the chemical herbicide for preventing and controlling the mikania micrantha has low cost and quick effect, but is easy to cause harm to the environment and generate drug resistance. The biological control means that natural enemies of mikania micrantha are introduced to inhibit growth and multiplication of mikania micrantha, and a tree method for planting mikania micrantha to inhibit harm of mikania micrantha, a tree method for planting mikania micrantha to inhibit harm of mikania micrantha and the like are adopted, but new species invasion is easily generated.
The method for preventing and treating mikania micrantha which is most widely used at present also belongs to chemical prevention and treatment, but the existing herbicide in the market has the defects of good effect on environment without removing the herbicide, poor effect on environment without removing the herbicide, and lack of a medicament with good effect on preventing and treating mikania micrantha with low effect on environment.
Disclosure of Invention
One of the objects of the present invention is to solve the above-mentioned deficiencies of the prior art, and to provide a mikania micrantha control agent which has a low effect on the environment and other plants while effectively controlling the harmful plant mikania micrantha, and which is characterized by a long-lasting effect and little resistance.

In some embodiments, the sum of the amounts of the fluroxypyr meptyl ester and the glyphosate isopropylamine salt is 19.5% to 36.4% of the total amount of the agent.
In some embodiments, the content ratio of the fluroxypyr meptyl ester to the glyphosate isopropylamine salt is (4-6): (45-60). The combination proportion is the optimal proportion obtained through a large number of field experimental researches, compared with other chemical components, the combination proportion is high in safety, good in preventing and removing effect on harmful plant mikania micrantha, and capable of reducing residual quantity in soil as far as possible in the process of long-term use in the world.
In some embodiments, the medicament further comprises a vegetable essential oil auxiliary agent, wherein the content of the vegetable essential oil auxiliary agent accounts for 4.0-8.3% of the total amount of the medicament. The plant essential oil auxiliary agent improves the penetration speed and the strength of the medicament, and quickly penetrates through a plant epidermal wax layer and an insect epidermal cuticle, so that the control effect of the medicament on insects, fungi and weeds is improved on the premise of not increasing the dosage, and the development trend of green agriculture is met.
The Mikania micrantha prevention and treatment agent has the beneficial effects that:
the control agent for mikania micrantha comprises the fluroxypyr-meptyl and the glyphosate isopropylamine salt with the concentration of 41 percent, wherein the fluroxypyr-meptyl is a conductive stem and leaf component and can effectively control malignant broadleaf weeds; the glyphosate isopropylamine salt with the concentration of 41 percent is a biocidal systemic conductive stem leaf component, and the glyphosate isopropylamine salt with the concentration of 41 percent is absorbed by green parts such as weed stem leaves and the like and is transmitted to each part in vivo to kill weeds with roots; due to the fact that the fluroxypyr meptyl and the glyphosate isopropylamine salt with the concentration of 41% are different aiming at different parts of the mikania micrantha, the fluroxypyr meptyl and the glyphosate isopropylamine salt are synergistic, pesticide dosage can be effectively reduced, pesticide effect can be kept, the effect is lasting and remarkable when the fluroxypyr meptyl and the glyphosate isopropylamine salt are actually applied to prevention and treatment of the mikania micrantha, the drug resistance of the mikania micrantha can be reduced, the harm to other plants is small, for example, arbor, shrub, fruits and vegetables and the like are basically not influenced, and the fluroxypyr meptyl and the glyphosate isopropylamine salt are suitable for being applied to forest lands.
In order to achieve the second purpose, the invention provides the following technical scheme:
the method for preventing and treating the mikania micrantha is characterized in that the mikania micrantha prevention and treatment agent is added into clear water and uniformly mixed, the adding amount of the mikania micrantha prevention and treatment agent is 3-4 g/L, and the uniformly mixed agent is applied to mikania micrantha cultivated land before the blooming period of the mikania micrantha.
In some embodiments, an adhesive is also employed, and is added in an amount of 0.1g/L to 0.4 g/L. The adhesive facilitates the formulation and use of the medicament and extends the adhesion time of the medicament.
In some embodiments, the adhesive is a dry laundry powder.
The method for preventing and treating mikania micrantha has the beneficial effects that:
the method for preventing and treating mikania micrantha can be applied by mixing all components, and is suitable for large-scale production and application, wherein the mikania micrantha is prevented and removed before blooming to slow down the spreading of the mikania micrantha, and the optimal spraying period is provided.
