AbstractThe surface spreading behavior of pesticide determine its deposition, uniformity and biological effectiveness on plant foliage. During present study, the spreading capacity of Euphorbia antiquorum (EA) and Euphorbia tirucalli (ET) latex-based 2.5% emulsifiable concentrate (EC) formulation was evaluated using para film as a model surface. Dilutions ranging from 0.03% to 1.0% were prepared, and spreading diameters were measured after 1 minute of application. The results revealed a concentration-dependent increase in spreading up to 0.10 %, followed by a slight decrease at 1.0 %. Euphorbia tirucalli formulation showed superior spreading across all concentrations as compared to Euphorbia antiquorum. The study highlighted surfactant and wetting characteristics of Euphorbia latex and provides direction for biopesticide formulation.
