Eco-Oriented Formulation and Stabilization of Oil–Colloidal Biodelivery Systems Based on GC-MS/MS-Profiled Phytochemicals from Wild Tomato for Long-Term Retention and Penetration on Applied Surfaces for Effective Crop Protection

Abstract

Vegetable oils as hydrophobic reserves in oil dispersions (OD) provide a practical approach to halt bioactive degradation for user and environment-efficient pest management. Using biodegradable soybean oil (57%), castor oil ethoxylate (5%), calcium dodecyl benzenesulfonates as nonionic and an-ionic surfactants, bentonite (2%), and fumed silica as rheology modifiers, we created an oil−colloidal biodelivery sytem (30%) of tomato extract with homogenization. The quality-influencing parameters, such as particle size (4.5 μm), dispersibility (97%), viscosity (61 cps), and thermal stability (2 years), have been optimized in accordance with specifications. Vegetable oil was chosen for its improved bioactive stability, high smoke point (257 °C), coformulant compatibility, and as a green build-in-adjuvant by improving spreadability (20−30%), retention and penetration (20−40%). In in vitro testing, it efficiently controlled aphids with 90.5% mortalities and 68.7−71.2% under field-conditions without producing phytotoxicity. Wild tomato-derived phytochemicals can be a safe and efficient alternative to chemical pesticides when combined wisely with vegetable oils.

Environmentally Benign Design of Renewable Oleoresin-Bioenergized Imidacloprid Nanohydrocolloids for Improved Activity, Lower Toxicity, and Agroecological Sustainability

“…Higher pH values result in settling particles forming rougher masses, which settle more quickly from the tube’s top to its bottom. The findings are consistent with earlier research, which found that acidity or alkalinity changed at a far slower rate during storage …”

“…Safety Evaluation of Cotton. NS and SC solutions were used to soak appropriate numbers (10) of seeds of uniform size and fullness at various doses (0.5, 5, 50, and 500 mg L −1 ), whereas the control group received the same treatment with deionized water. The seeds were put in filter paper-lined Petri dishes (9 cm in diameter) with 10 seeds per group and three duplicates after soaking for 24 h at 25 °C.…”
