The objective of this work was to evaluate the phytotoxic effect of insecticides, acaricides and fungicides alone and in combination, on papaya plants, cv. Sunrise Solo Improved Line 72/12, under field and summer conditions. The experiment were conducted in a private farm, located at São Mateus county, the most important papaya region in the State of Espírito Santo. The experiment, arranged in a randomized block design with four replications, were conducted. Each plot consisted of three plants. The products with their respective dose in a volume of 100 l H2O were:chlorothalonil (Daconil PM -200g); mancozeb (Dithane PM - 200g); Cupric oxychloride (Reconil - 400g); thiabendazole (Tecto 45 - 100ml).; dicofol + tetradifon (Carbax - 200ml); triazophós (Hostathion 400 BR - 150ml); fenbutatin oxide (Torque 500 SC - 60ml); and abamectin (Vertimec 18 CE - 50ml). Hostathion 400 BR was phytotoxic to adult papaya plants, mainly when associated with other chemical products.The fungicides Daconil BR, Reconil and Tecto 450; the fungicide-acaricide Dithane PM; the acaricides Carbax and Torque 500 SC; and the inseticide-acaricide Vertimec 18 CE, applied lonely, did not affect plant growth and production, and did not cause leaf and burns injury. These association of fungicides and fungicide-acaricide, with each other acaricides or inseticide-acarice, showed neither phytotoxic reactions, growth pattern alterations nor leaf injury and burning.
