Abstract: A liquid seed treatment composition is described in which microdried bacteria are flowably suspended in a nonphytotoxic liquid carrier with a chemical substance normally toxic to the bacteria. The bacteria in the compositions exhibit prolonged viability relative to dry, non-fluid formulations. To sustain bacterial viability and effectiveness of the compositions, the compositions are maintained as a liquid colloid in which the ingredients are thoroughly dispersed.

Abstract: Compounds useful as plant growth regulators having the formula: ##STR1## WHEREIN X and X' are each halogens, R and R' are each alkyl groups containing from 1 to 4 carbon atoms and n and n' each have a value from 1 to 5. Method of preparing said compounds is also disclosed.

Abstract: Various dialkylammonium-2,4-dichlorophenoxyacetates having the formula ##STR1## wherein R.sub.1 and R.sub. 2 are radicals each selected from the group consisting of methyl and ethyl, are useful as plant growth regulators. Mono-substituted alkylamines are not suitable for processing into compounds of this invention. The compounds of the invention exhibit excellent water solubility characteristics and possess an exceptionally high and unexpected degree of effectiveness as a general weed killer on lawns, pasture lands, ponds, lakes, canals, ditches, etc. Methods of using and preparing these compounds are disclosed.
