Apple fibrous heart disease is a complex and multifactorial condition that occurs during the infection process of apple trees, involving various weak parasitic bacteria. As environmental conditions change and farming practices evolve, this sub-general disease has increasingly become a major threat in recent years. Particularly in 2008, the situation worsened significantly, drawing widespread concern from both farmers and researchers. However, many fruit growers still have misconceptions about the prevention and treatment of this disease due to technical limitations, leading to ineffective control measures.
One common mistake is the reluctance to apply pesticides during the flowering period. This is actually the most critical time for preventing and controlling apple mold disease, as pathogens enter the fruit during this stage. If not addressed properly, the disease can spread rapidly, increasing the risk year by year. Farmers often avoid using chemicals during this period out of fear that it might affect yield, which results in missed opportunities for effective intervention.
In terms of pesticide selection, many farmers opt for cheaper chemical options due to rising input costs, despite their limited effectiveness. For example, carbendazim and thiophanate-methyl are commonly used but have shown poor control outcomes and may negatively impact fruit setting and cause deformation. On the other hand, biological agents like polyoxin, clobenzoate, and others have proven more effective with minimal interference in fruit development. It's recommended to apply these early in the flowering and fruit-setting stages, using fine spray nozzles and avoiding application after 4 p.m. to prevent unnecessary fruit drop.
Another issue is the over-reliance on chemical control while neglecting cultural practices. Factors such as dense orchard structures, poor light penetration, and low-quality fruit bags contribute significantly to disease incidence. However, many farmers focus only on spraying, which provides only temporary relief. To achieve long-term control, it's essential to implement proper orchard management: choose dwarf varieties with high light efficiency, prune to improve air circulation, and use breathable, high-quality fruit bags instead of cheap alternatives.
Lastly, apple fibrous heart disease is influenced by multiple factors including weather, location, and bag quality, making its control unpredictable. Some years see good results, while others do not. Therefore, farmers are advised to consult agricultural experts to develop site-specific strategies for better disease management. With a combination of scientific knowledge and practical adjustments, the impact of this disease can be effectively reduced.
