Toxic effects of pesticides products on papaya plant (Carica papaya L.) cv. sunrise solo improved line 72/12

In this work was studied the phytotoxic effect of inseticides, acaricides and fungicides alone and in combination, on papaya plants (Carica papaya L.); cv. Sunrise Solo Improved Line 72/12, under field conditions. The experiment were conducted in a farm, located at São Mateus county, the most important papaya region in the State of Espírito Santo.The experiment was arranged in a randomized block design with four replications, with three plants by plot. The products with their respective dose in a volume of 100 l H2O were: abamectin (Vertimec 18 CE - 50 ml); dicofol + tetradifon (Carbax - 200 ml); fenbutatin oxide (Torque 500 SC - 60 ml); mancozeb (Dithane PM - 200g).; cuprix oxychloride (Reconil 400g) and thiabendazole (Tecto 450 - 100ml). Plants were evaluated for plant high, number of leaves, flowers and fruits, and extension of leaf injury, one day before, 15 and 30 days after spray. Vertimec 18 CE in combination with Reconil or Tecto 450, caused light leaf injuries, observed only15 days after spraying. These plants recovered from leaf injury and 30 days later, no leaf lesion was observed. Dithane PM, Reconil, Tecto 450, Carbax, Torque 500 SC, Dithane PM + Carbax , Dithane PM + Torque 500 SC, Dithane PM + Vertimec 18 CE, Reconil + Carbax, Reconil + Torque 500 SC, Tecto 450 + Carbax and Tecto 450 + Torque 500 SC, did not affected plant growth and yield studied. No leaf burns injury were caused in papaya plants.
