Effects of Application of Various Reduced-risk Pesticides to Tomato, with Notes on Control of Greenhouse Whitefly

Abstract: Experiments conducted in greenhouse and field environments investigated the acute and chronic phytotoxic effects of several house-hold and commercially available soaps, detergents, and oils applied to tomato (Lycoperiscum esculentum Mill.). In addition, the effect of these treatments on greenhouse whitefly, Trialeurodes vaporarium (Westwood), was investigated. In the greenhouse experiments, the number of whiteflies observed was negatively correlated… Show more

“…Slight but significant nymph reduction (compared to the control) was observed when M-Pede insecticidal soap was sprayed at 2% (v/ v), not causing yield losses. Weekly applications were suggested to control T. vaporariorum in tomato greenhouses, without plant toxicity risk [69]. Several other detergents (e.g., Ivory Clear detergent) used at 2% significantly reduced nymph density, but they also caused damage on the plant and yield reduction.…”

“…Plant toxicity was observed, particularly on plants with pubescent epidermis. In another report [69], the activity of two detergents on M. persicae nymphs and adults was evaluated by spraying (SU 120) or immersion (Tecsa fruta), in the laboratory. The last detergent was significantly more active (having a smaller LC 50 , considering the smaller amount of active ingredients, that is, surfactants in the formulation) regardless of the aphid instar.…”
