| 摘要 |
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.
