The silicate compost (basic slag from metallurgy) use was evaluated as a resistance inductor against leafminer (Liriomysa spp) on two chrysanthemum cultivars. The experiment was carried out in a greenhouse, in Espirito Santo State, Brazil. The experimental design was completely randomized, in split split plot scheme, with five repetitions, being two varieties of chrysanthemum (Puritan and Yellow Diamond) allocated in the plot and in the subplot five doses of basic slag (0.00; 1.40; 2.80; 4.20 and 5.60 g pot -1) and in the subsubplot the weeks. The evaluations were carried out weekly, during nine weeks, observing the presence of leafminer and the number of mines in each leaf. The basic slag from metallurgy showed to be potential against the leafminer. The two chrysanthemum cultivars also showed differences in susceptibility to leafminer attack.
