FITOTOXICIDADE DE FUNGICIDAS, ACARICIDAS E INSETICIDAS, SOBRE O MAMOEIRO (Carica papaya L.) CULTIVAR SUNRISE SOLO IMPROVED LINE 72/12 EM CONDIÇÕES DE CAMPO

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 Sao Mateus county, the most important papaya region in the State of Espirito 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); triazophos (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.
