Effect of (pyrrolidine-2,2-diyl)bisphosphonic acid on Raphanus sativus and Trifolium repens : first observations

Résumé

Linear biphosphonic acids have already been reported to have herbicidal properties. The purpose of these preliminary tests was to verify the effect on radish and clover plants of the (pyrrolidine-2,2-diyl)bisphosphonic (1) acid, having a nitrogenic cycle. The first observations upon the use of a solution containing (1) show that watered and sprayed on radish sprouts show a higher stem growth rate but the tested clovers, sprayed on, died within a week. In conclusion, it seems that spraying the product over the leaves and watering the soil with tap water have more effect, may it be in a good or bad way, than just applying the product in the soil. (1) seems to have a fertilizing effect on Raphanus sativus but a herbicidal one on Trifolium repens.
