When using fungicides, use only when needed since this avoids unnecessary selection for resistant populations. Using dormant copper sprays and removing inoculum sources such as leaves (using urea or a flail mower), mummified fruit, and dead twigs/branches reduces the initial pathogen population. Avoid selecting sites with high disease pressure since this increases the chance of selecting for resistant fungi. As a result, the chance of resistance decreases. Using resistant varieties, minimizing tree stress, and maintaining proper soil fertility reduces disease incidence since pathogens do not reproduce well on trees that are less susceptible to disease. Often have a very specific mode of action against fungi.Ĭultural Control and Fungicide Use Patternsĭue to environmental conditions, disease is inevitable in the Mid-Atlantic growing region and use of chemical controls is a necessity however, following cultural practices that favor decreasing disease pressure will help decrease the opportunity for resistance.Control disease by protectant and/or curative action.Aliette, ProPhyt, Rampart, Ridomil Gold SL). Aprovia, Indar, Luna Tranquility, Merivon, Topsin) or throughout the whole plant (e.g. Move within the plant, either systemic locally (within the leaf, or translaminar, e.g.Systemic fungicides prevent disease from developing on parts of the plant away from the site of application and are classified as FRAC Group fungicides with numbers, which:
