Description
AQUEOUS HERBICIDAL INTERMIXTURES
TECHNICAL FIELD OF THE INVENTION
The invention relates to herbicidal intermixtures. More particularly, the invention relates to essentially aqueous homogeneous herbicide compositions comprising electrolytic herbicides and a multipart amine component.
BACKGROUND OF THE INVENTION
Controlling unwanted plants is of high importance in agriculture. Over the years, various strategies have been developed for effective control of these unwanted plants. Depending upon the region it is necessary to find or develop appropriate techniques for desired weed control. A large part of the surface of the world is arid, characterized as too dry for conventional rain fed agriculture and hence it demands for precise or specific weed control techniques.
"Arid" implies prolonged dryness, and is used with respect to the climate and the land below it. In such regions the ability to produce agricultural crops is restricted.
Usually on arid lands the potential evaporation of water from the land exceeds the rainfall. The land may be characterized according to the degree of aridity as dry forest, chaparral or brushland, grassland or savannah, or desert. "Arid" does not adequately characterize the soils, however, for they may vary in many ways.
Often they are alkaline or saline.
An arid ecosystem differs in many respects from one of tropical or temperate zones. Unlike temperate zones, an arid zone is characterized as an area of low precipitation, high temperature, and high rate of evaporation. Frequency of rainfall does not describe accurately the type of the arid zone nor does the amount of precipitation govern the type of vegetation.
Among the various agronomic practices that could bring about immediate positive results in dryland and arid areas, optimum and effective weed control is the first and foremost management practice. However many weeds growing naturally in the

An arid ecosystem differs in many respects from one of tropical or temperate zones. Unlike temperate zones, an arid zone is characterized as an area of low precipitation, high temperature, and high rate of evaporation. Frequency of rainfall does not describe accurately the type of the arid zone nor does the amount of precipitation govern the type of vegetation.
Among the various agronomic practices that could bring about immediate positive results in dryland and arid areas, optimum and effective weed control is the first and foremost management practice. However many weeds growing naturally in the
2 arid region have evolved a more complicate overall drought adaptation strategy which usually involves several mechanisms of drought escape, tolerance and avoidance. The leaf shedding option, the tight stomatal control and the development of a prolific root system are all specific characteristics developed by the vegetation destined to grow in arid regions. The plants adopt to osmoregulation and increase in elasticity of the cell and a decrease in cell size. Due to such natural adaption of the plants/weeds to the specific conditions, they are tougher than those growing under normal conditions and is difficult to control. Further such weeds have thick and waxy cuticle layers defending them from the penetration of any use of foliar herbicides. It has been observed that the commonly used non-selective herbicide such as glufosinate based formulations were not providing an effective weed control in arid regions.
Glufosinate is a non-selective foliage application type herbicide which kills or controls many species of weeds. In the Pesticide Manual 15th Edition, glufosinate has been described as being widely used in burn-down segments, and for control of a wide range of broad-leaved weeds and grasses and sedges in cereals, cotton, corn and soy, fruit orchards, vineyards, rubber and oil palm plantations, ornamental trees and bushes, non-crop land, and pre-emergence in vegetables.
Glufosinate being a contact herbicide is known to be used with various adjuvants to improve the efficacy or to induce certain specific properties as required.
US6642177 discloses that to be effective, glufosinate must be formulated with a high concentration of surfactants to get the required bio efficacy.
DE 3931051 discloses salts of herbicidal acids with long-chain nitrogen bases such as fatty amines.
It has been observed by the inventors of the present invention that existing formulations of non-selective herbicide such as glufosinate is not effective as desired particularly in arid environments. In view of such observation, there is a necessity for developing more effective formulations which are physically stable as

Comparative compositions (Example 15 and Example 16) and market sample of glufosinate ammonium (Liberty 280 SL Glufosinate ammonium) were also tested to compare the results. The observations at 7 days, 14 days and 21 days after application were summarized in below table (table 1).

It has been noted that due to natural adaption of the weeds to the arid conditions, they are tougher than those growing under normal conditions and was difficult to control. Further these weeds displayed thick and waxy cuticle layers defending them from the penetration of the herbicide spray. It has been noted that the commonly used glufosinate based formulations and market sample of glufosinate were not providing an effective weed control in arid regions.
The inventive compositions even at a low rate, is found to be highly efficacious in controlling tough weeds in the area.
