Description
Technical Field
The present invention relates generally to herbicidal compositions for crop production management. More specifically, the present invention provides synergistic compositions and methods for controlling a broad spectrum of weeds of the present invention.
Background
The background description includes information that may be helpful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the present invention, or that any publication specifically or implicitly referenced is prior art.
To fully exploit the genetic yield potential of crops, proper weed control is one of the essential elements. Weeds not only reduce yield, but also present difficulties in the harvesting operation. Therefore, effective weed control is critical in order to maintain grain production to keep up the growing population and ensure grain safety. Manual and mechanical methods are laborious, tedious and expensive due to increased labor costs, and do not effectively manage weeds simply due to crop simulation. Thus, there is a need to devise an economical and less time consuming method to increase crop yield. One such method is a chemical method using herbicides. However, most herbicidal formulations have limitations such as phytotoxic effects on crops, leaf deformation, leaf color change and more side effects.
The new agricultural strategies expand irrigation, employing high yielding varieties under heavy fertilization conditions, greatly help to increase the growth, yield and productivity of wheat crops, but these strategies also stimulate the growth of various weed lines faced by wheat growers, possibly resulting in significant yield losses. Poor competition includes broadleaf weeds and grasses. Weeds account for about one third of the total number of losses caused by all pests. Thus, the use of chemical weeding has become necessary.
Various chemical methods have been developed to date for crop production management by combining various herbicides and using such formulations, however, such formulations are not as effective for treating all deleterious effects of crop plants.
Chemical weeding is the most ideal, practical, effective, up-to-date, time-saving and economical means for reducing early weed competition and crop production loss. However, complete reliance on the same herbicide results in environmental pollution, and some weed species develop resistance and inter-and intra-species conversion.
In view of the challenges faced by existing methods, there is a need to design and evaluate the efficacy of suitable post-emergent herbicides alone and in mixtures to effectively control broadleaf weeds and grasses to aid in resistance management.

When weeds reached the two to four leaf stage, all treatments were applied as post-emergence foliar. Spraying is carried out with the aid of a battery-powered knapsack sprayer. The percent efficacy was calculated 14 days and 21 days after herbicide application.
Weeds present in the experimental field: chenopodium album, rumex lights, anagalis arvensis, medicago denticulata, solanum nigrum, argemone maxicana, parthenium hysterophorus, melilotus indica, phalaris minor.
The amount of herbicide premix molecule applied, the various weed flora tested, and the results given in the table below:
table 1: after application of synergistic activity of herbicidal composition against main weeds of wheat at fourteen days
Table 2:
table 3:
TABLE 4 synergistic Activity of herbicidal compositions against major wheat weeds 21 days after application
Table 5:
table 6:
/>
the results, as shown in tables one, two, three, four, five and six, clearly demonstrate that the synergistic effect of the premix molecules controls various weeds after fourteen and twenty-one days of herbicide application. This difference between the observed and expected efficacy clearly indicates a longer duration of synergistic effect combination.
Phytotoxicity of weeding combination on wheat
Table 7. Visual observations of phytotoxicity, such as tip/surface damage and wilting, are recorded on a scale of 0-10 (below) 3, 5, 7, 10 and 15 days after herbicide application.
Table 8: influence of herbicidal composition on wheat phytotoxicity
At the recommended dose, no phytotoxicity or crop injury or leaf burn etc. was recorded for the wheat crop, but at double doses of treatments 4 and 5, yellowing of leaf tips was observed on day 5 after herbicide application. On days 7 and 10, the tips were burned and growth was still slightly retarded compared to other treatments. However, on day 15, the crop was fully recovered and the new growth of the plant was observed to be fully healthy and normal.
Table 9: effect of herbicide ingredients on wheat yield
The data in Table nine shows that all herbicidal treatments significantly increased wheat yield override. In all herbicidal treatments, the grain yield was obtained for the first treatment (four thousand eight hundred eighty nine kg/ha) and was on level with treatments two and three.
