Prolonged periods of leaf wetness, high temperatures, and relative humidity during spring/summer are ideal conditions for
the development of apple diseases in Brazil. In 2012, European canker, caused by Neonectria ditissima was officially confirmed
in Brazilian apple orchards. The disease has a high potential to adversely affect fruit production as all symptomatic
branches and/or all apple trees need to be eliminated to contain the epidemic in the orchards. Knowledge of N. ditissima
spore release is required to optimize management practices because it facilitates the prediction of European canker infection
risks and improves disease management decisions. Thus, the objective of this study was to investigate the release of
N. ditissima spores from apple plants and detached branches over time. In the São Joaquim region of Brazil, both conidia
and ascospores of N. ditissima can be released from cankers alive and/or dead in apple tissues year-round. In Brazil, peaks
of spore release from N. ditissima were observed in traps when there was rainfall, irrespective of the season. Ascospore
peaks were more frequent and higher than those of conidia trapped in both traps and apple tissues. Detached branches of
symptomatic apple trees actively released spores of N. ditissima in the three years of evaluation, but in smaller numbers in
comparison to traps with live plants. Thus, new and rigorous management measures should be adopted to control European
canker dissemination in Brazilian apple orchards. MenosProlonged periods of leaf wetness, high temperatures, and relative humidity during spring/summer are ideal conditions for

O trabalho foi conduzido no municipio de nova Erechim, no ensaio de competicao de cultivares para recomendacao na regiao Oeste de Santa Catarina. As amostragens foram quinzenais, observando-se o numero de ninfa e adultos do percevejo de renda em cinco folhas por parcela, em 10 variedades de mandioca de primeiro e segundo ciclos. Em avaliacoes realizadas de janeiro a marco de 1985, verificaram -se diferencas acentuadas de ataque do inseto entre as variedades utilizadas. Os resultados evidenciaram que tanto em mandioca de primeiro ano como de segundo ano, as variedades Gigante e Paraguaio foram as mais atacadas, enquanto as variedades Petico, Branquinha e Vassourinha foram as menos preferidas. como inimigos naturais encontram-se formas jovens de dipteros sirfideos e de crisopideos, alem da forte incidencia de uma bacteria entomopatogenica a partir de marco, atacando ninfas e adultos do percevejo de renda. |
