Zusammenfassung:The invention is relevant to the field of herbicides, in particular to dry formulations of herbicides such as wettable powder, water-dispersible granular, and powder suspension herbicidal compositions. Compositions for preparation of wettable-powder and powder suspension herbicidal products containing low-melting agrochemical agents, such as bromoxynil esters, are provided. Preferred compositions are co-melts of bromoxynil esters with at least one additional herbicide or pesticide, particularly atrazine. The compositions of the invention have higher melting points than the bromoxynil ester component, and therefore have advantages in that the use of solvents and/or carriers in formulations can be avoided or minimized. The compositions can be processed into dry powders without the problems associated with the softening or melting of pure bromoxynil esters during grinding or milling, and without the need for dilution of the product with substantial amounts of inactive carriers. Compositions containing the alloys do not lose selectivity in the presence of oil adjuvants.
