Embodiment 1

[0036] A preparation using the composition of the present application for preventing and controlling garden dodder plants as an active ingredient, in terms of mass percentage, its components and proportioning ratio are as follows:

[0037] Material A:

[0038]

[0039]

[0040] Material B:

[0041]

[0042] Its preparation method is:

[0043] (1) Preparation of material A: heat and stir triafenturate, isophorone, methyl ethyl ketone, and alkylaryl polyoxyethylene polyoxypropylene ether to form an oil phase; add silicone defoamer to water and stir After uniformity, it is the water phase. Under the condition of shearing, add the oil phase to the water phase, emulsify with high-speed shearing in an emulsifier, and homogenize with a homogenizer.

[0044] (2) Preparation of material B: Mix alkylarylphenol formaldehyde condensate polyoxyethylene ether, fatty alcohol polyoxyethylene ether, xanthan gum, methylparaben, and water evenly, and stir under the condition of high-...

Embodiment 2

[0047] A preparation using the composition of the present application for preventing and controlling garden dodder plants as an active ingredient, in terms of mass percentage, its components and proportioning ratio are as follows:

[0048]

[0049] The preparation method is as follows: uniformly mix alkylarylphenol formaldehyde condensate polyoxyethylene ether, fatty alcohol polyoxyethylene ether, xanthan gum, methylparaben, sodium benzoate, glyphosate salt, and water, and mix at high speed Under the condition of stirring the dispersant, add the original medicine of amfenflumezone. The obtained mixture is put into a horizontal sand mill and sand-milled until the average particle size is below 5um, and then the material is discharged, which is used to prevent and control dodder plants.

Embodiment 3

[0051] 1. Test object: Chinese dodder on Ficus xiaoye and privet privet

[0052] 2. Test method: Divide 12 blocks of the same size on the sliced ​​Cuscuta chinensis, and spray according to the test treatment. 40 Chinese dodders with consistent growth conditions were selected from each block as the measurement index. Each treatment was repeated three times.

[0053] 3. Drug efficacy investigation: observe and record the reactions of Cuscuta chinensis (deformation, blackening, wilting, death, etc.) and parasitic plants' reactions (safety) every day after taking the medicine. At 3d, 10d, and 50d after spraying, investigate and record the surviving numbers of 40 Cuscuta chinensis selected in each treatment block, and calculate the control effect. The specific test results are shown in Table 1.

[0054] Calculation formula of control effect: P=(D0—D1) / D0×100

[0055] In the formula: P——control effect %.

[0056] D0—the survival number of Chinese dodder in the blank control.

Abstract

The invention discloses a composition and a preparation for preventing and eliminating garden cuscuta plants and applications of the composition and the preparation. The composition consists of a contact selective triazolinone type herbicide and a systemic herbicide in a mass ratio of 1:(0.1-10), wherein the contact selective triazolinone type herbicide and the systemic herbicide are combined together according to a certain weight ratio to improve the effect of preventing and eliminating cuscuta parasitic plants, and are safe for hosts at the same time. The composition and the preparation are used for preventing and eliminating the parasitic cuscuta plants among garden plants, so that while a quick and complete preventing and eliminating effect is achieved, the ornamental effect of the garden plants is not influenced. A test proves that the component selection and proportioning in the technical scheme provided by the application have a synergistic effect on preventing and eliminating the cuscuta plants, and the preventing and eliminating rate can reach more than 99%.

Description

technical field [0001] The invention relates to the field of herbicides, in particular to a composition, preparation and application for controlling garden dodder plants. Background technique [0002] Cuscuta is a kind of annual parasitic herbaceous plant, the plant is very lush, the stem is winding, yellow, slender, about 1.5mm in diameter, multi-branched, parasitic roots can be born everywhere, extending into the host body, leaves are scarce, scale-shaped, triangular-shaped eggs Shape, flowers bisexual. There are about 170 species of dodder plants, which are widely distributed in warm temperate regions all over the world, mainly in America. There are 8 species in our country, which are golden lantern vine (also known as Japanese dodder), hop dodder, single-column dodder, and large flower dodder in the subgenus of single column, Cuscuta chinensis and dodder in the subgenus of thread stems; Cuscuta dodder in the subgenus of dodder. , European dodder. [0003] The physiolo...
