FIELD OF INVENTION
The Invention related to a process lor the Preparation of an Herbicide wettable powder. espeeially a broad Spectrum Composition, which is suitable for application by mixing with water providing a suspension suitable for use as a spra\ on areas effecting by Phalaris minor. Avenafalua. Poa annua. Trianthema Species.. Cyperus diformis. Convolvulus arvenisis of weeds in Wheal, maize, sorghum.
BACKGROUND TO INVENTION AND PRIOR ART
We have now discovered that by mixing the two different herbicides. The effectiveness of the wettable powder when diluted with water is ol' very high order in case o\' commonly encountered herbicide such as Phalaris minor. Avenafatua. Poa Annua. Trianthema Species.. Cyperus diformis. Convolvulus arvenisis of weeds in Wheat, maize, sorghum.
We have also discovered thai the lleld of Application of the herbicide can be broadened byincorporating in the composition several other herbicides. Indeed, it appear that mixture of herbicides in right proportion, in definite composition, results in synergistic mortality response, yielding surprisingly high bioefficacy over abroad classes o\' weeds. The composition could also be used a herbicide for wheat, maize, sorghum.
DEFINITION OF THE INVENTION
The Invention provide a Herbicide Wettable Powder Comprising :
A. at least two different active ingredients selected from the different group ol
weedicides and Mixture thereof
B. at least one dispersing agents selected from the group and the moxture theof and
C. at least one wettiim agents selected from the uroup and the mixture there of and
D. at least one filler selected from the group and mixture thereof.
I he invention more particularly provides a herbicide wettable powder with higher stability comprising.
1. This invention relates to new herbicidal composition comprising a mixture of N.
N" - Dimethyl - N - 4 - Isopropy I Phenyl I rea and ethyl ester ol' 2. 4-1) Dichloro Phenoxyacetaie. It also relates to the use of the mixture and to a method ol' Controlling Weeds.
2. The present invention provides a method lor controlling the growth ol" weeds.
The amount of the herbicide wettable powder applied vary with the nature of the weeds. The Composition used, the lime of application, the climate and edaphic conditions and (where used to control the growth of weeds in crop growing areas) the nature ol' the crops. When applied to a crop - growing area, the rate of application should be sufficient to control the growth of weeds without causing substantial permanent damage to the crop. However it is to be understood that higher or lower application rales may be used, depending upon the particular problem of weeds control encountered.
The herbicide wettable powder may be used to control selectively the growth weeds.
