Embodiment 1

[0036] A preparation using the composition of the present application for preventing and controlling dodder plants as an active ingredient, in terms of mass percentage, its components and proportioning 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 pyrenzazone, sulfonyl triadimenone, isophorone, methyl ethyl ketone, alkylaryl polyoxyethylene polyoxypropylene ether to form an oil phase; The foaming agent is added into water and stirred evenly to form the water phase. When the shearing condition is small, 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 conditio...

Embodiment 2

[0047] A preparation using the composition of the present application for preventing and controlling dodder plants as an active ingredient, in terms of mass percentage, its components and proportioning 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, and water, and stir under the condition of high-speed dispersant stirring Next, add the original drug of sulfonytriazolone and the original drug of bispyribac and stir evenly. 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 capable of preventing and eliminating cuscuta parasitic plant,a preparation and applications thereof. The composition comprises touch-out selective triazolinone herbicide and a systemic herbicide according to the mass ratio of 1:(0.1-10), and the touch-out selective triazolinone herbicide and a systemic herbicide are combined according to certain weight ratio, the prevention and elimination effects of the cuscuta parasitic plant can be enhanced, and safety to host is achieved; the composition and the preparation are used for preventing and eliminating the cuscuta parasitic plant in the landscape plant, and the ornamental effect of the landscape plant is not influenced while the fast and thorough prevention and elimination effect are achieved. Trials proved that the selection and proportion of the components in the technical scheme have synergistic interaction effects on the prevention and elimination of the cuscuta parasitic plant, and the prevention and elimination rate is more than 99%.

Description

technical field [0001] The invention relates to the field of herbicides, in particular to a composition, a preparation and an application thereof for controlling parasitic plants of the genus Cuscuta. 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 ...
