Description

Aqueous herbicidal mixtures
Technical Field
The present invention relates to herbicidal mixtures. More particularly, the present invention relates to substantially aqueous homogeneous herbicidal compositions comprising an electrolytic herbicide and a multi-part amine component.
Background
The control of undesirable vegetation is of great importance in agriculture. Over the years, various strategies have been developed to effectively control these undesirable vegetation. Depending on the region, it is necessary to find or develop a technology suitable for desired weed control. Most of the earth's surfaces in the world are relatively arid and are characterized by excessive drying for traditional rain-fed agriculture, thus requiring precise or specific weed control techniques.
"drought" means a long period of drying and is used to describe the climate and the land beneath it. In such areas, crop production capacity is limited. Generally on dry land, the potential evaporation of water from the land exceeds rainfall. The land may be characterized according to the extent of drought as an early forest, a bush or shrub, a grassland or tropical sparse grassland, or a desert. However, "drought" is not sufficient to characterize soil because they may change in many ways. They are usually alkaline or saline soils.
Drought ecosystems differ from one of the tropical or temperate ecosystems in many ways. Unlike the temperate zone, the arid zone is characterized by regions of low precipitation, high temperature, and high evaporation rate. The rainfall frequency can not accurately describe the type of the arid zone, but also the rainfall for determining the vegetation type.
Among the various agronomic measures that can produce direct positive results in dry and arid areas, optimal and effective weed control is a primary management measure. However, many weeds that naturally grow in arid areas have evolved more complex global drought adaptation strategies that typically involve several mechanisms of drought escape, tolerance, and avoidance. Leaf abscission selection, strict stomatal control and development of high-fertility roots are all specific characteristics developed by vegetation destined to grow in arid regions. Plants adopt osmotic regulation and cell elasticity increases and cell size decreases. Due to such natural adaptation of plants/weeds to specific conditions, they are tougher and difficult to control than those grown under normal conditions. In addition, such weeds have a thick waxy cuticle layer, thereby protecting them from penetration by any foliar herbicides used. It has been observed that commonly used non-selective herbicides such as glufosinate-based formulations do not provide effective weed control in arid areas.
Glufosinate is a non-selective foliar-applied herbicide that kills or controls many weed species. In the Pesticide handbook, 15 th edition, glufosinate has been described as widely used in the burn-off phase and for controlling a wide range of broadleaf weeds and grasses and sedges in cereals, cotton, maize and soybeans, orchards, vineyards, rubber and oil palm plantations, ornamental trees and shrubs, uncultivated areas and pre-emergent vegetables.
Glufosinate is known as a contact herbicide to be used with various adjuvants to enhance efficacy or induce certain specific properties as desired. US6642177 discloses that in order to be effective, glufosinate must be formulated with high concentrations of surfactant to obtain the desired bioefficacy.
DE 3931051 discloses salts of oxalic acid with long chain nitrogenous bases such as fatty amines.
The present inventors have observed that existing formulations of non-selective herbicides such as glufosinate are not as effective as desired, especially in arid environments. In view of such observations, there is a need to develop more effective formulations that are physically stable and biologically effective regardless of the environment, such as arid or non-arid regions.
In view of the above, the main object of the present invention is to design and prepare a novel composition of glufosinate which is highly effective especially in dry areas where the weeds have thick waxy leaves and are difficult to penetrate by common foliar herbicidal formulations.

The composition is diluted with water and applied to broadleaf weeds, grasses and sedges in arid areas.
After treatment with the composition prepared according to the invention (example 14), necrosis of the weeds after chlorosis was observed, which demonstrates the biological efficacy of the new composition. Comparative compositions (examples 15 and 16) and market samples of glufosinate ammonium (Liberty 280SL glufosinate ammonium) were also tested to compare results. Observations 7, 14 and 21 days after application are summarized in the following table (table 1).

The field test results as shown in the above table clearly show that the composition according to the invention is extremely effective for weed control in arid areas. It has been noted that weeds are tougher and difficult to control than those grown under normal conditions due to their natural adaptability to drought conditions. In addition, these weeds exhibited a thicker waxy cuticle layer, thereby protecting them from penetration by herbicide sprays. It has been noted that the commonly used glufosinate-based formulations and market samples of glufosinate fail to provide effective weed control in arid areas. It has been found that the compositions of the present invention are highly effective in controlling tough weeds in such areas, even at low application rates.
The present invention is more specifically explained by the above-mentioned examples. It will be understood, however, that the scope of the present invention is not limited in any way by these examples. It should be understood by those skilled in the art that the present invention includes the above-described embodiments, and may be further modified and changed within the technical scope of the present invention.
