Improving Insecticide Activity and Rain-Fastness with Polyethylenimine

Source

Many surfactant or polymer-based adjuvants designed to improve the adhesion of active ingredients on plants function through mechanisms involving surface tension modification or hydrogen bonding. Polyethylenimine, a branched polyamine with high molecular weight and cationic charge density, offers a different adhesion promotion mechanism based on the formation of ionic bonds with anionic substrates combined with an ability to orient itself with organic active ingredients.

The product is particularly beneficial with pesticide actives which function through a contact mechanism and demonstrates an ability to improve pesticide efficacy particularly in terms of rain-fastness, adhesion, heavy metal complexation, biodegradation, and initial fixation level.
