Baseline sensitivity of Amphobotrys ricini to fluazinam and thiophanate-methyl. Repositório Alice
SOARES, D. J.; DATOVO, C. de O..
Amphobotrys ricini is the causal agent of castor gray mold, one of the most destructive diseases of castor crops. Fungicides are frequently used to manage plant diseases, however no information on the baseline sensitivity of A. ricini to fungicides is available. The aim of the present work was to determine the baseline sensitivity of A. ricini to the fungicides fluazinam and thiophanate-methyl based on 47 isolates from Goias (n=3), Maranhão (n=1), Mato Grosso (n=12), Paraíba (n=3), Rio Grande do Sul (n=18) and São Paulo states (n=10). Mycelial disc (6 mm) removed from 4-day-old colonies were transferred to Petri dishes containing Potato-Dextrose-Agar (PDA) amended with the fungicides in different concentrations. The Petri dishes were then maintained in the...

Baseline sensitivity of Brazilian Mycosphaerella fijiensis isolates to protectant and systemic fungicides. Repositório Alice
GOMES, L. I. S.; BIBIANO, L. B. J.; SILVA, G. F. da; HANADA, R. E.; MIZUBUTI, E. S. G..
Black Sigatoka caused by Mycosphaerella fijiensis is a foliar disease that affects banana plants and large amounts of fungicides are required to prevent crop losses. Intensive applications of single-site fungicides can select for fungicide-resistant isolates. The objective of this study was to assess the sensitivity of 60 isolates of M. fijiensis to commonly used fungicides.
