Drying of agrochemical droplets on a model surface: co-localization of adjuvant and active ingredient
A systemic active ingredient and the adjuvant(s) in the formulation have to end up in the same place on the leaf surface when a droplet of spray dries on the leaf to be effective, as is widely believed, though firm evidence is lacking. The behaviour of drying agrochemicals is studied using model formulations of a systemic fungicide with a nonionic, a cationic or an amphoteric adjuvant.

The effect of an esterified copolymer of glycerol on the performance of bacterial biopesticides
Greenhouse trials demonstrated that the adjuvant Elasto G5 (esterified copolymer of glycerol) has a positive effect on the performance of XenTari (Bacillus thuringiensis var. Aizawai) and Serenade (Bacillus subtilis strain QST 713), respectively. XenTari was applied against the golden twin-spot moth (Chrysodeixis chalcites) in peppers and Serenade against powdery mildew in cucumbers and potted roses. Further investigations on drop deposits using light microscopy revealed that the adjuvant enhanced the contact area between the biopesticide and the leaf surface. We suggest that this explains at least a part of the improved performance.

Adsee ST4 – A sustainable solution for seed treatment
Adsee ST4 is a binder for the seed treatment application and it is a copolymer derived from >50% renewable content. This binder is giving increased adherence of pesticide formulations on seeds with decreased dust-off, no phytotoxicity and no decreased flowability of seeds.

Interaction between plant cuticular compounds, active ingredients, and adjuvants
Adjuvants like surface active agents and oils interact with the plant cuticle. Cuticles are composed of components of different physicochemical properties, including aliphatic and alicyclic wax fractions. Our focus is on the interactions of active ingredients and adjuvants with these components, because there have been no studies on the contribution of these wax fractions to the cuticular permeability of active ingredients.
