Abstract

The genus Trichoderma is represented by non pathogenic fungithat exercise antagonism to several phytopathogens through the parasitismand/or antibiosis and, have been used as biocontrole agents, growthpromoters and to improve the germination and sanity of seeds. The objectiveof this work was to compare the efficiency of the biological and chemicaltreatment in the sanity of seeds of forrage turnip (Raphanus sativus L.),black oat (Avena strigosa S.), rye (Secale cereale L.) and the emergency ofseedlings of forrage turnip. The evaluation of the sanity was done throughthe method of filter paper, and for evaluation of the emergency and seedlingsdevelopment, using styrofoam trays in the green-house.Were tested: T1 Rhodiauram®SC (500g/Kg of Thiram); T2 - Agrotrich®; T3 Rhodiauram®SC + Agrotrich®; T4 - Rhodiauram® SC (2:00) +Agrotrich® and T5 - Control. The treatments that controlled 100% theincidence of the fungi of the seeds of black oat were T1 and T4; of ryewere the treatments T1, T2, T4; and of forrage turnip the treatments T2and T4. The seeds of black oat and rye did not germinate due to physiologicproblems. For the forrage turnip, significant difference was not verifiedamong the treatments for the emergency test and emergency speed, andthe treatments T2, T3 and T4 presented the largest seedlings heights. Thebiocontrol product Agrotrich® alone or in combination with chemicalcontrol improved the sanity of forrage turnip, black oat, and rye and theheight of forrage turnip seedlings.
