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] Embodiment 1—Comparative example 1-25 is to the toxicity determination experiment 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), and Isoba Senecio-C (collected from Sichuan Province Baoxing County, Ya’an City, Sichuan Province), Xianhua Senecio-D (collected from Mount Emei, Sichuan Province), Rough Leaf Senecio-E (collected from Leibo County, Liangshan Yi Mount Emei, Sichuan Province) There are six varieties of Senecio in total.

[0101] 2) Collection method of test objects: during the collection process, forage grass and other weeds (such as plantain, bermudagrass, weeds, etc.) in the same ecological environment are collected together and potted together. The influence of other weeds in the environment, when Senecio grows vigorously, it is used as the target weed for testing.

[0102] 3) Test met...

Embodiment 2

[0127] The field efficacy test after the composition of embodiment 2-control example 15,16,18,24 is processed into preparation

[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 each preparation obtained was used to control the three varieties of the aforementioned Senecio, respectively, varieties A, C, and F; Water control.

[0129] Method of use: Dissolve or disperse the obtained preparations in clear water to prepare solutions or suspensions, and spray the obtained solutions or suspensions at 750kg (suspension or solution) / ha evenly in each experimental area divided equally. The active ingredient usage rate of the sprayed medicament is 240 grams / hectare.

[0130] Grass and other weeds also exist in each test area, including plantain, bermudagrass, and weed.

[0131] Measuring method of drug efficacy: Investigate the number of remaining Senecio plants in each exp...

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...
