Hello , Mixing 19:19:19 fertilizer with Novaluron, Emamectin benzoate, Hexaconazole, and Validamycin in a single spray is not advisable because it increases the risk of phytotoxicity, clogging, and reduced effectiveness of the products. While Novaluron and Emamectin are generally compatible as insecticides, and Hexaconazole and Validamycin can work together as fungicides, combining all five with a fertilizer in one tank can stress the crop. The safer practice is to divide them into two sprays—for example, apply 19:19:19 with one fungicide in one round, and use the insecticides with the other fungicide in a separate round. Before spraying, always perform a jar test by mixing small amounts in water to check for any reaction, and apply only the recommended dosages. It is also wise to first spray a small trial area before covering the entire crop.
