Abstract
Abstract Disclosed are hydrolytically stable spray oil containing plant assimilating boron compounds for improving plant growth. Suitable boron compounds include the esters of boric, boronic and borinic acids including the cyclic esters, the alkanolamine esters, the non-alpha hydrogen and branched alkyl esters and amine-borate adducts. The spray oils are formulated to contain from 0.01 to 2.0 weight/volume percent of boron.

Claim 1
Independent Claim
148 words
A process for supplying boron to plants which comprises applying thereto a horticultural hydrolytically stable spray oil having a Gravity API of 31-50, a viscosity at 100° F. of 81 to 87 Saybolt Universal Seconds and a boiling range of 85° to 775° F. and a minimum unsulfonated residue of 85% and containing from 0.01 to 2.0 weight percent boron in the form of a hydrolytically stable oil soluble boron compound selected from the group consisting of: B(OR) 3 , R'B(OR) 2 and R 2 B(OR) in which R and R' are radicals having at least 6 carbon atoms selected from the group consisting of alkyl, cycloalkyl, aryl, aralkyl, alkaryl; R being the same or different in a given compound and R' also representing hydrogen; boric, boronic, and borinic acid esters derived from alkane, alkane-diols, and alkanolamines; and amine borate adducts and amine salts of tetra-covalent boron compounds.
