The effect of calcium silicate on the management of leafminer fly and muskmelon powdery mildew and post-harvest quality was evaluated in the field using a completely randomized design with 26 replicates. The evaluations were performed at 7, 14, 21, 28 and 35 days after removal of the TNT blanket. At the end of the crop cycle, post-harvest fruit quality was evaluated where 75 fruits harvested at random from each area with and without calcium silicate were evaluated for physical and chemical characteristics in 5 storage periods (0, 21, 28, 35 and 42 days) and 5 replicates, with 3 fruits per replicate. Calcium silicate decreased the severity of powdery mildew and foliar lesions caused by the leaf mines (Liriomyza spp) and provided greater firmness, lower mass loss and did not alter physical and chemical characteristics such as total soluble solids and titratable total acidity of the fruits during post-harvest storage.
