Abstract

Abstract The present invention relates to novel agents for increasing the basipetal translocation of agricultural chemicals such as plant growth promoters, inhibitors, fungicides, insecticides or herbicides hereinafter referred to as "bioactants". The present agent comprises a mixture of N-heterocyclic amide and a haloethyl phosphonic acid in a mole ratio of between about 5:1 and about 1:10, employed in an inert carrier at a concentration between about 25 ppm to about 10,000 ppm which mixture can be applied to a plant prior to, or simultaneously with, the bioactant. The translocating agent may be a mixture of the N-heterocyclic amide, e.g. N-methyl-2-pyrrolidone, and the haloethylphosphonic acid, e.g. 2-chloroethylphosphonic acid, it may comprise a mixture of said components with the complexed compound derived from the addition of said components or it may be the complexed compound per se.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 52 words
A basipetal-enhanced, herbicidal, translocating composition consisting essentially of a phytotoxic amount of a postemergent herbicide and a basipetal-promotional translocating and phytotoxic increasing amount of a basipetal-promotional translocating agent consisting essentially of a mixture of N-methylpyrrolidone or polyvinylpyrrolidone and a 2-haloethylphosphonic acid combined in a mole ratio between about 1:5 and about 10:1.
Claim 2
Dependent Claim 52 words
A basipetal-enhanced, herbicidal, translocating composition consisting essentially of a phytotoxic amount of a postemergent herbicide and a basipetal-promotional translocating and phytotoxic increasing amount of a basipetal-promotional translocating agent consisting essentially of a mixture of N-methylpyrrolidone or polyvinylpyrrolidone and a 2-haloethylphosphonic acid combined in a mole ratio between about 1:5 and about 10:1.
Claim 3
Dependent Claim 17 words
The composition of claim 1 wherein said translocating agent is a mixture of N-methyl-2-pyrrolidone and 2-chloroethylphosphonic acid.
Claim 4
Dependent Claim 38 words
The process of contacting a plant with a postemergent herbicide and a translocating agent of claim 1 in an amount effective to promote basipetal translocation of said herbicide and to increase the phytotoxic effect of said postemergent herbicide.
Claim 5
Dependent Claim 33 words
The process of claim 3 wherein the translocating agent is an aqueous solution of a mixture of N-methyl-2-pyrrolidone and 2-chloroethylphosphonic acid combined in a mole ratio of from about 1:5 to about 10:1.
