Abstract
The chemical herbicide for preventing and killing mikania micrantha is one kind of synthetic chemical herbicide and consists of 70 % concentration sulfometuron-methyl aqua, tribenuion-methyl and washing powder or detergent as adhering agent in certain proportion. The present invention has raised adhering capacity, and thus can be attached to leaf, root and other important parts of mikania micrantha to kill it. It has high herbicidal effect and lasting effect of 0.5-1 year.
Description
Technical field:
The present invention relates to a kind of chemical agent of preventing and kill off Mikania micrantha, it belongs to a kind of synthetic chemical herbicide.
Background technology:
Mikania micrantha is the important weeds of studying in the world, very easy layer growth, expansion in group, thus cover other plant or vegetation, cause the shrub that climbed up by holding on to, dungarunga and tightly covered to more than ten meters high big tree.Thick stem, leaf and the flower of Mikania micrantha weighs on the canopy top of being climbed up by holding on to plant, formed the microhabitat that plant is suffocated, and makes plant lack sunlight, nutrient and moisture, and photosynthesis can not normally carry out, and final plant death causes very big harm.Killed trees kind is a lot of.Several different methods such as adopted chemical control, biological control at present or manually root out is not effectively controlled spreading and endangering of Mikania micrantha.Existing chemical agent kind of preventing and kill off Mikania micrantha is many, for example: with 2.4-D, glyphosate etc., but the result shows: the 2.4-D of 50-500 times of solution and glyphosate all can only be killed the ground trophosome of Mikania micrantha, can not thoroughly kill root, its root can be with the very fast germinating individuality that makes new advances, by the quick growth of clone system, cover degree is recovered to reach 100% in 2-3 month.Simple sulfometuron-methyl all has significant killing effect to Mikania micrantha.Experimental result shows: the solution that the sulfometuron-methyl water solube powder is mixed with, be sprayed on the Mikania micrantha cauline leaf, and dosage is at 1-1000g/hm
2The time, can thoroughly kill Mikania micrantha at 2-3 month.It is respond well that but sulfometuron-methyl does not have in the hillside fields under the situation in marshy land, and killing effect reaches 100%; And concentration (0.001-0.1g/m when low
2) drug effect is also better, has an effect fully executing to imitate in 2 months, Mikania micrantha recovered in 1 year again; But because sulfometuron-methyl obtains dilution easily in water, when in depression, ground, marshy land, using, because the concentration of medicine can not remain on a higher level, so the lasting effect of drug effect then is subjected to very big influence, and this mainly is because the root of failing to kill Mikania micrantha.
Summary of the invention:
Purpose of the present invention is being no matter provide a kind of is in the hillside fields or the chemical agent of preventing and kill off Mikania micrantha that all can thoroughly kill Mikania micrantha in water ground at short notice.
The object of the present invention is achieved like this:
A kind of chemical agent of preventing and kill off Mikania micrantha is characterized in that its composition comprises sulfometuron-methyl and sticking and adhesive agent, and the weight ratio of described sulfometuron-methyl and sticking and adhesive agent is: 1: 3-1: 0.23; Described sulfometuron-methyl is 70% Sulfometuron Methyl water solube powder.
It comprises that also one is re-dubbed and is divided into tribenuron-methyl, and described sulfometuron-methyl, tribenuron-methyl is sticking and the adhesive agent weight ratio is: 1: 1: 3-1: 1: 0.23.
Described sticking and adhesive agent is washing powder or liquid detergent.
The present invention utilizes existing sulfometuron-methyl medicament, improved the adhesive ability of sulfometuron-methyl medicament, make that the present invention can be in use firm attached to significant points such as the leaf of Mikania micrantha and roots, effectively utilize the weeding ability of sulfometuron-methyl, improved the use effect, can be so that Mikania micrantha can show tangible symptom of chemical damage in 24 hours after dispenser: the end bud be wilted, and foxiness appears in the blade face.In active ingredient is 0.01～0.05g/m
2Consumption under, still can obtain effect preferably to the control of Mikania micrantha.Sub-district and large tracts of land result of the test illustrate that all the kill ratio of Mikania micrantha reaches 70～100%, half a year to one lasting period year.
Embodiment:
Embodiment 1: composition of the present invention in the present embodiment comprises: sulfometuron-methyl and washing powder.
In the present embodiment, sulfometuron-methyl 1.5 gram restrained with washing powder 5 mix, be dissolved into again in 15 to 20 kilograms the water, evenly be sprayed at the surface of blade or the rhizome of Mikania micrantha with sprayer.Dose is controlled to be: the Mikania micrantha growth time is below 2 years, can be with low prescription dose, and the Mikania micrantha growth time is more than 5 years, with high prescription dose.
To prevent and kill off 100 square metres Mikania micrantha is example, illustrates that specifically to make the dosage effect as follows:
At 0.1～0.5g/m
2High dose under, the kill ratio of Mikania micrantha is 100%, the lasting period is all more than 1 year, no significant difference between each dosage.Preponderate (cover degree is more than 60%) weeds cover degree 〉=100%, Mikania micrantha, under the situation of natural plant height 30～80cm, 0.01～0.1g/m
2Sulfometuron-methyl can receive fabulous preventive effect: Mikania micrantha kill ratio 100%, the lasting period is more than 1 year; Be lower than 0.01g/m
2The time, then preventive effect correspondingly reduces along with the minimizing of consumption.
To the group of Mikania micrantha cover degree more than 70%, more than the vegetation thickness 50cm, adopt 0.1～0.5g/m
2Formulation rate control Mikania micrantha, no significant difference between each dosage all can 100% kills Mikania micrantha, the lasting period is all more than 1 year.Therefore, adopt 0.1g/m
2, promptly the formulation rate of 1kg/ha can thoroughly be eradicated Mikania micrantha, and Mikania micrantha does not have demutation in 1～2 year.
In dominant thick grass of Mikania micrantha and filling thick grass, be that the cover degree of Mikania micrantha is greater than 70%, under weeds cover degree 〉=100%, the situation more than the natural plant height 50cm, want to obtain the effect of well-content control Mikania micrantha, it is Mikania micrantha kill ratio 100%, no longer demutation more than 1 year, the then consumption 〉=0.1g/m of sulfometuron-methyl
2Get final product.
0.01～0.05g/m
2Consumption under, still can obtain effect preferably to the control of Mikania micrantha.Sub-district and large tracts of land result of the test illustrate that all the kill ratio of Mikania micrantha reaches 70～100%, half a year to one lasting period year; Lower dosage, i.e. 0.0005～0.01g/m
2, the growth of Mikania micrantha is obviously suppressed, but and part withered.
Embodiment 2: in the present embodiment, the present invention includes three compositions: sulfometuron-methyl, tribenuron-methyl and liquid detergent.With sulfometuron-methyl 13 gram, the tribenuron-methyl and the liquid detergents of 13 grams are mixed into medicament for 3 milliliters, are dissolved in 15 to 20 kilograms the water again, evenly are sprayed at the surface of blade or the rhizome of Mikania micrantha with sprayer.
The control of the usage amount of present embodiment is identical with embodiment 1 with effect.
