[0027] The mass ratio between aminopyralid and cloflupyridine, the components of the active ingredient, is 1.1:1.2.

[0028] The mass ratio between the component 24-epibrasinolide, sodium alginate and sclerotinia of the synergistic safener is 0.05:0.9:0.9.

[0029] A wettable powder with an active ingredient mass percentage of 2.3% is formulated according to a conventional preparation method.

Embodiment 2

[0031] A pyridine herbicidal composition containing brassinolide compounds, comprising an active ingredient and a synergistic safener, the active ingredient is composed of aminopyralid and cloflupyridinate, and the synergistic safener consists of 28 - Composition of high brassinolide, sodium alginate and sclerotinia.

[0032] The active ingredient accounts for 3.5% by mass of the herbicidal composition, and the synergistic safener accounts for 2.50% by mass of the herbicidal composition.

[0033] The mass ratio between aminopyralid and cloflupyridine, the components of the active ingredient, is 1.1:2.4.

[0034] The mass ratio between component 28-homobrasinolide, sodium alginate and sclerotinia of the synergistic safener is 0.1:0.9:1.5.

[0035] According to the conventional preparation method, the oil suspension concentrate with an active ingredient mass percent content of 3.5% is prepared.

Embodiment 3

[0037] A pyridine herbicidal composition containing a brassinolide compound, comprising an active ingredient and a synergistic safener, the active ingredient is composed of aminopyralid and cloflupyridate, and the synergistic safener consists of a Acyl brassinolide, sodium alginate and sclerotinia net composition.

[0038] The active ingredient accounts for 3.4% by mass of the herbicidal composition, and the synergistic safener accounts for 3.05% by mass of the herbicidal composition.

[0039] The mass ratio between aminopyralid and cloflupyridine, the components of the active ingredient, is 2.2:1.2.

[0040] The mass ratio of propionylbrassinolide, sodium alginate and sclerotin among the components of the synergistic safener is 0.05:1.5:1.5.

[0041] According to the conventional preparation method, it is prepared into a suspension concentrate with an active ingredient mass percent content of 3.4%.

Abstract

The invention discloses pyridine weeding composition containing brassinolide compounds. The composition comprises active components and synergistic safeners, wherein the active components comprise aminopyralid and florpyrauxifen-benzyl; the synergistic safeners comprise the brassinolide compounds, sodium alginate and dimethachlon. According to the composition, aminopyralid and florpyrauxifen-benzyl with different herbicidal spectra and complementary advantages and disadvantages are selected and form a mixture for use, so that the weed control spectrum is expanded, the weeding effect is obviously improved, the possibility of phytotoxicity to crops in season and residual toxicity to subsequent crops is also avoided, and occurrence and development of single-dose resistance are effectively delayed.

Description

technical field [0001] The invention relates to the technical field of compound synergistic herbicides, in particular to a pyridine herbicide composition containing brassinolide compounds. Background technique [0002] my country has a long history of planting rice and has a vast territory. It is one of the main rice producing countries in the world. The weeds that harm rice fields mainly include barnyardgrass, daughter daughter, paspalum, crabgrass, foxtail, goosegrass, oat grass, wild oats and other gramineous weeds; Broad-leaved weeds such as Moshangcai, jiejiecai, jiayebo, hollow lotus seedlings, and annual capes, heteromorphic sedge, broken rice sedge, cow felt, sunshine floating Buddha grass, Cyperus cyperus, and water centipede Grass weeds. [0003] Chemical weeding is one of the main means of controlling weeds in agriculture. In recent years, due to the large-scale single use of some herbicide varieties, many weeds have developed resistance. At the same time, whe...
