ABSTRACT
Mites, mainly red mites Tetranychus urticae, are a limiting factor for tomato production in Niger. They are found at all production sites, where they often cause greater production losses. To minimize the losses, micronized sulfur at a rate of 800g/kg was tested at the experimental station in a Fisher block design with 4 replications. It was compared with an abamectin-based acaricide. At doses of 7.5 kg/ha, 11.25 kg/ha and 15 kg/ha, the micronized sulfur significantly reduced red mite populations. At these doses, the efficacy of the product was also reflected 80% of yield increases as compared to the absolute control (no insecticide applied). The reference acaricide, abamectin, is comparable to the dose of 7.5 kg/ha of micronized sulfur.
