摘要:
Certain metal salts of certain substituted pyrazole compounds are employed as the active nitrification inhibitor in the presence of reduced nitrogen fertilizers. Compositions containing these salts can be applied to the surface of soil and can remain on said soil surface for up to 3 days or more without incorporation into the soil and retain at least about 70 percent of the pyrazole in the salt in the composition.

Certain metal salts of certain substituted pyrazole dithiocarbamates are employed as the active nitrification inhibitor in the presence of reduced nitrogen fertilizers. Compositions containing these salts can be applied to the surface of the soil and can remain on said soil surface for up to 3 days or more without mechanical incorporation into the soil and retain at least about 70 percent of the pyrazole as the salt in the composition.

Certain metal complexes of certain substituted pyrazole compounds are employed as the active nitrification inhibitor in the presence of reduced nitrogen fertilizers. Compositions containing these complexes can be applied to the surface of soil and can remain on said soil surface for up to 3 days or more without mechanical incorporation into the soil and retain at least about 70 percent of the pyrazole in the complex in the composition.
摘要:
Disclosed are herbicidal concentrate formulation compositions having reduced grass crop plant phytotoxicity comprising certain sulfonamide or sulfonylurea herbicides in admixture with a non-herbicidal organic or inorganic acid or mixture thereof in an amount sufficient to insure that during the post-emergent agricultural uses thereof in water diluted form the pH of the mixture is below about 5; also disclosed is the preparation of said compositions, aqueous formulations of said concentrate and the use of said formulations.
