Embodiment 1

[0036] A kind of preparation that takes the composition of the application for preventing and controlling garden dodder as an active ingredient, in mass percent, its components and proportions 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 trioxafen-ethyl, isophorone, methyl ethyl ketone, alkyl aryl polyoxyethylene polyoxypropylene ether to form an oil phase; add silicone antifoaming agent to water and stir After homogenization, it is the water phase. Under shearing conditions, the oil phase is added to the water phase, emulsified by high-speed shearing in an emulsifier, and homogenized by a homogenizer.

[0044] (2) Preparation of material B: the alkyl arylphenol formaldehyde condensate polyoxyethylene ether, fatty alcohol polyoxyethylene ether, xanthan gum, methylparaben, and water are mixed uniformly, and under the condition of high-spe...

Embodiment 2

[0047] A kind of preparation that takes the composition of the application for preventing and controlling garden dodder as an active ingredient, in mass percent, its components and proportions are as follows:

[0048]

[0049] The preparation method is as follows: the alkyl arylphenol formaldehyde condensate polyoxyethylene ether, fatty alcohol polyoxyethylene ether, xanthan gum, methylparaben, sodium benzoate, glyphosate salt and water are mixed evenly, Under the condition of stirring the dispersant, add the original drug of imiflufen. The obtained mixture is added into a horizontal sand mill and sanded to an average particle size of less than 5um to be discharged, and is prepared for the control of Cuscuta.

Embodiment 3

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

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

[0053] 3. Efficacy investigation: The reaction of Chinese dodder (deformation, blackening, wilting, death, etc.) and the reaction of parasitic plants (safety) were observed and recorded every day after the treatment. At 3d, 10d, and 50d after the treatment, the surviving number of 40 Chinese dodders selected in each treatment block was investigated and recorded, and the control effect was calculated. The specific test results are shown in Table 1.

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

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

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

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. Background technique [0002] Dodder is an annual parasitic herb, 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, the leaves are sparse, scaly, triangular eggs Shape, flowers bisexual. There are about 170 species of Cuscuta, which are widely distributed in warm temperate zones around the world, mainly in America. There are 8 species in my country, which are the golden lamp vine (also known as Japanese dodder), hop dodder, single column dodder, and large flower dodder; southern dodder and dodder of the subgenus Cordyceps; dodder of the subgenus Dodder , European dodder. [0003] Dodder plants have a special physiological structure. There are no chloroplasts in the cells they consist of. The...
