Embodiment 1

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

[0037] Material A:

[0038]

[0039]

[0040] Material B:

[0041]

[0042] The preparation method is:

[0043] (1) Preparation of material A: Heat and stir the fentrazone, sulfonyl triadimefon, isophorone, methyl ethyl ketone, and alkyl aryl polyoxyethylene polyoxypropylene ether to form an oil phase; eliminate the silicone The foaming agent is added to the water and stirred evenly and becomes the water phase. When the shearing condition is small, add the oil phase to the water phase, shear and emulsify in an emulsifier at high speed, and homogenize with a homogenizer.

[0044] (2) Preparation of material B: Mix the alkyl aryl phenol formaldehyde condensate polyoxyethylene ether, fatty alcohol polyoxyethylene ether, xanthan gum, methyl paraben, and water evenly, and mix it with high-...

Embodiment 2

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

[0048]

[0049] The preparation method is as follows: the alkyl aryl phenol formaldehyde condensate polyoxyethylene ether, fatty alcohol polyoxyethylene ether, xanthan gum, methyl paraben, sodium benzoate, water are mixed uniformly, and the condition of high-speed dispersant stirring Next, add sulfonyl triadimefon original medicine and bispyrifen original medicine and stir evenly. The obtained mixture is added to a horizontal sand mill to be sand-milled to an average particle size of less than 5um, and the material is produced to control Cuscuta plants.

Embodiment 3

[0051] 1. Test subjects: Ficus microphylla and Chinese Cuscuta on Ligustrum lucidum

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

[0053] 3. Investigation of efficacy: observe and record the reaction of Chinese dodder seeds (deformation, blackening, wilting, death, etc.) and the reaction of parasitic plants (safety) every day after the medicine. At 3d, 10d, and 50d after treatment, the number of surviving 40 Chinese dodder seeds 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] The calculation formula of the control effect: P=(D0—D1) / D0×100

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

[0056] D0——The surviving number of Chinese ...

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, preparation and application for preventing and controlling parasitic plants of the genus Cuscuta. Background technique [0002] Cuscuta is an annual parasitic herb. The plant is very luxuriant. The stem is twined, yellow, slender, with a diameter of about 1.5mm. It is multi-branched and can grow parasitic roots everywhere, extending into the host body, with few leaves, scaly, triangular-shaped eggs Shape, flower bisexual. There are currently about 170 species of Cuscuta, which are widely distributed in the warm temperate zone of the world, mainly producing America. There are 8 species in our country, namely the golden vine (also called Japanese Cuscuta), hops Cuscuta, Cuscuta serrata, and Cuscuta grandiflora; Southern Cuscuta and Cuscuta of Cuscuta subgenus; Cuscuta dodder of Cuscuta subgenus , European Cuscuta. [0003] The Cuscuta plants have a special physiological structu...
