Problems solved by technology

The plant Senecio Emei has been successfully colonized in the Baoxing area of ​​Ya'an City, Sichuan Province, but because no biological control measures were taken during the colonization process, it spread rapidly in the original ecological scenic spot of Shenmulei. And it has seriously affected the ecological environment of the scenic spot. At the same time, it has invaded the local pastures, causing accelerated degradation of the local pastures, seriously destroying the balanced development of the local ecological environment, and has a tendency to spread explosively

Embodiment 1

[0099] Example 1-Comparative Example 1-25 Toxicity Test of Senecio

[0100] 1) Test subjects: Emei Senecio-A (collected from Baoxing County, Ya'an City, Sichuan Province), Liangshan Senecio-B (collected from Leibo County, Liangshan Yi Autonomous Prefecture, Sichuan Province), Alien Senecio-C (collected from Sichuan Baoxing County, Ya'an City, Province), Splendid Senecio D (collected from Mount Emei, Sichuan Province), Rough Leaf Senecio E (collected from Leibo County, Liangshan Yi Autonomous Prefecture, Sichuan Province), and Ehe Senecio F (collected from There are six Senecio varieties in Emei Mountain, Sichuan Province.

[0101] 2) Method of collecting test objects: During the collection process, the pastures and other weeds in the same ecological environment (such as plantain, bermudagrass, clover, etc.) are collected together and potted together to simulate the comprehensive environmental assessment and screening. The impact of other weeds in the environment, when Senecio grow...

Embodiment 2

[0127] Example 2-Field efficacy test after processing the compositions of Comparative Examples 15, 16, 18, and 24 into formulations

[0128] The compositions of the aforementioned comparative examples 15, 16, 18, and 24 were processed into preparations according to the contents of Table 3, and the obtained preparations were used to control the three species of Senecio, namely species A, C, and F; Water control.

[0129] How to use: Each of the obtained preparations is dissolved or dispersed in clean water to prepare a solution or suspension. The obtained solution or suspension is sprayed evenly in each experimental area divided equally at 750kg (suspension or solution) / ha The effective ingredient usage amount of the sprayed medicament is 240 g / ha.

[0130] Forage grass and other weeds, including plantain, bermudagrass, and schrenckweed, also exist in all experimental areas.

[0131] Efficacy calculation method: Investigate the number of remaining Senecio in each experimental area 15 ...

Abstract

The invention discloses a weed prevention and control combination and preparation as well as application thereof, and particularly relates to a senecio prevention and control combination and preparation as well as application thereof. The senecio prevention and control combination contains fomesafen and clopyralid in mass ratio of 1: (0.15-10). The combination has an effective prevention and control effect on senecio, thus stopping the growth of the senecio or killing the senecio so as to prevent the senecio from destroying the ecological environments and sustainable development of pastures or forest farms.

Description

Technical field [0001] The invention relates to a composition, a preparation and an application for preventing and controlling weeds, and in particular to a composition, a preparation and an application for preventing and controlling Senecio. Background technique [0002] The classification of plant groups is mainly divided into six categories: phylum, class, order, family, genus, and species. The levels of each type start from phylum and gradually decrease until species. Species is the basic unit of plant classification, which refers to plant groups with certain natural distribution and certain physiological and morphological characteristics. Different individuals of the same species have the same genetic traits, and hybridization with each other can produce fertile offspring. Different individuals Crossing individuals between species usually fails to produce offspring or produces sterile offspring. The basic unit of plant classification is the species. According to the ge...
