Prevention of late-maturing peach brown rot

The cool weather is now the key period for the prevention and treatment of peach brown rot when the late peach varieties are ready for picking, gradually changing color, and accepting harvest.

Peach brown rot bacterium is an airborne pathogenic fungus, and the residual fruit is the best breeding ground for brown rot. Therefore, Taoyuan, which is located in the periphery of the fruit distribution center (especially the scattered underground wind direction), should timely clear the remaining fruits of the early ripe and middle ripe peach and discard the fruit. Residues, fruit discards, and naturally occurring fruits and fruit branches can be buried in soil below 45 cm to reduce the infection of brown rot pathogens in the air against late-maturing varieties.

Freshly pocketed fruit cells are young and easily injured. Therefore, attention should be paid to the weather and the market. Picking bags at the picking day; preparing protective bactericides before picking bags, consulting with the local plant protection department for pesticide selection, and spraying protective bactericides immediately after bag removal.

In addition, accurately calculate the safety interval, timely harvested fruit that has been transformed; pay attention to avoid direct sunlight, appropriate pre-cooling, correct placement, remove the defective fruit fruit wounds, ensure the relative humidity of cold storage 90% -95 % and 0 °C storage conditions; if possible, before the storage of the fruit, use ultraviolet light to decontaminate the air in the warehouse for 20-25 minutes; if the disease is found, gently seal it with a sealing bag and get it buried outside the reservoir. Avoid re-infestation caused by pathogenic bacteria scattered in the air in the library.
