Evaluating the Efficacy of Garlic Extract in Managing Red Spider Mite in Tomatoes

This study assessed the effectiveness of garlic extract in controlling red spider mites (Tetranychus urticae) in tomatoes. A randomized complete block design (RCBD) with three replications was used to evaluate the efficacy of different concentrations of garlic extract (10%, 20%, and 30%) compared to Abamectin (positive control) and water (negative control). The results showed that the 30% garlic extract treatment exhibited potent repellent and lethal effects on red spider mites, comparable to Abamectin, with significant control observed 24 hours after treatment. Notably, the 30% garlic extract treatment resulted in zero moving mites and minimal egg-laying, similar to Abamectin. The study suggests that garlic extract, particularly at higher concentrations (30%), has potential as a targeted mite control agent in tomato production, offering a sustainable and environmentally friendly alternative to chemical pesticides for managing red spider mite infestations.
