Raising the Influence of Insecticides against Spodoptera littoralis (Lepidoptera: Noctuidae) and Reducing Field Recommended Dose by Blending with Adjuvants to Simulate Eco-Friendly Formulations

Abstract

A wide variety of adjuvants surfactants are available fair therefore need to choose a suitable surfactant to give maximum system enables to choose proper surfactant with ease and enhanced the insecticide effectiveness and raises the perseverance of insecticides. This study swivel, the influence of adjuvants Triton ® X-405 (Octylphenol ethoxylate), Codacide oil), Silwet Gold ® (Trisiloxane Alkoxylates) to enhance the toxicity of (Lufenuron, Profenofos, and cypermethrin) as mercantile insecticides recommended against Egyptian cotton leafworm (CLW) Spodoptera littoralis. The results pointed out that the amalgamation of the adjuvants and halfrecommended field rate of insecticides increased the toxicity of tested insecticides and decreased the rate of field application, decreases the surface tension of spray solutions to a much lower range, high range of (HLB) hydrophile-lipophile balance. Moreover, comparing sedimentation after half an hour of mixing as well as foaming after half an hour of mixing results gives different values in Emulsion properties (foaming and Stability).

Enhancing >i<Dalbulus maidis>/i< (Hemiptera: Cicadellidae) control: an integrated approach combining >i<Cordyceps javanica>/i< (Ascomycota: Hypocreales) and insecticides

“…Following this experiment, a publication on the enhancing effect of Silwet and other adjuvants was released, and new bioassays were added to the schedule (El-Bassoiuny et al, 2023). The preparation of the spray solution using distilled water and its application to D. maidis aimed to evaluate with 0.05% Silwet L-77 enhanced the insecticides' effects.…”
