Doença é o mau funcionamento de células e tecidos do hospedeiro
que resulta da sua contínua irritação por um agente patógeno ou
fator ambiental e que conduz ao desenvolvimento de sintomas.
Doença é uma condição envolvendo mudanças anormais na forma,
fisiologia, integridade ou comportamento da planta. Tais mudanças
podem resultar em dano parcial ou morte da planta ou de suas partes
(Agrios, 1988).
 Fenômeno biológico
 Interferência em processos fisiológicos
 Caráter negativo da interferência
 Processo contínuo
De acordo com Stakman & Harrar (1957), a doença só
existe quando os sintomas, que caracterizam o desvio
do estado normal, são bem perceptível, causando
prejuízos (danos e perdas) correspondentes na
produtividade, qualidade do produto ou estética da
planta sejam significativos.
