ABSTRACT
TRANSLOCATION OF SISTEMIC FUNGICIDES IN STRAWBERRY AND EFFECT UPON Verticillium sp Nees es Wallr

Rudy H. Witt S.1 y Lautaro Cancino E.2
 

In strawberry plants, variety "Tioga" grown in the greenhouse the acropetal and basipetal translocation, as well as the persistence of the systemic fungicides Benlate (benomyl), Tecto 60 (thiabendazole), Cercobin M (methythiophanate), CELA W 524 (triforine), Derosal (carbendazole) and DAM 18654 (cypendazole) were studied. Benlate and Tecto 60 were alos used as treatments being acidified with hydrochloric acid. The effectiveness of control of Verticillium sp. Nees ex Wallr. of these products was studied in inoculated plants.
Translocation was biologically evaluated by means of the agar plate diffusion technique, using the fungus Verticillium sp.
To determine the acropetal translocation and persistence, the products were applied to the soil in a single dose. Basipetal translocation and persistence was determined by dipping the foliage of the plants in a suspension of the fungicide. In both cases, plants were planted in pots a week before treatment.
