Fruit drop disease , also roll in the hay as postbloom fruit cliff ( PFD ) , is a fungal infection that affects citrus trees . This disease causes the untimely falling off of fruitlets from the Sir Herbert Beerbohm Tree , result in a meaning expiration of potential yield yield . PFD is particularly associated with besotted conditions conditions during the blooming catamenia of citrus trees .

I have in person witnessed the devastating impact of PFD on citrus orchards during my years of experience in gardening and landscaping . It is disheartening to see the yield that has developed beautifully of a sudden dropping from the tree diagram and going to waste . The loss of possible harvesting can have significant economic consequences for citrus grower .

The principal perpetrator behind PFD is a fungus called Colletotrichum acutatum . This pathogen infects the flowers of citrous fruit trees during the blooming time of year , take to the subsequent yield drop . The fungus can survive in septic plant debris and stain , making it difficult to root out completely .

Wet weather condition , such as coherent rain or high humidity , make a favourable surround for the fungus to expand . The fungal spores are circularise through rain dab or wind , infecting the flowers and eventually head to fruit drib . This is why PFD is often associated with periods of heavy pelting or prolonged wetness during the blooming stage of citrus trees .

The symptoms of PFD typically appear a few weeks after infection . The septic fruitlets will start to show signs of decay , turning chocolate-brown and becoming shriveled . Eventually , they will come off from the Sir Herbert Beerbohm Tree prematurely . In serious case , a with child number of fruitlet may drop , importantly reduce the overall fruit yield of the tree .

Preventing and managing PFD requires a proactive approaching . Here are some strategy that can help extenuate the impact of this disease :

1 . Monitoring weather conditions : Keep a closemouthed eye on weather forecasts during the blooming period . If slopped weather is predicted , take preventive measure to protect the flowers from infection . This could include covering the trees with protective material or using overhead irrigation to wash off potential fungal spore .

2 . Pruning and sanitization : absent any infected plant stuff from the tree diagram and the surrounding country . This includes fallen fruitlets , numb flower , and infected twigs . Proper sanitization practices can help oneself foreshorten the spread of fungal spore and minimise the peril of reinfection .

3 . Fungicide app program : In stark cases or when high disease pressure is wait , antifungal agent can be used to suppress the fungous infection . Consult with a local agricultural denotation servicing or a professional horticulturist to determine the most appropriate antifungal agent and coating timing for your specific citrus varieties .

4 . Cultivar selection : Some citrus varieties are more susceptible to PFD than others . When planting new citrus trees , consider take cultivar that have show resistance or tolerance to this disease . Local greenhouse or agricultural expert can put up guidance on desirable varieties for your realm .

5 . ameliorate aviation circulation : Prune the citrus fruit tree to improve atmosphere circulation within the canopy . This can aid subjugate humidity degree and minimize the favorable status for fungal ontogenesis . Regular pruning also allows for better sun incursion , which can inhibit fungous development .

6 . Mulching and right irrigation : Apply organic mulch around the base of the tree to maintain wet levels and preclude sess growth . debar excessive irrigation , as overwatering can create a conducive environment for fungous ontogenesis . It is important to strike a balance between providing adequate moisture for the tree and avoiding waterlogged weather .

By follow through these strategies , citrus growers can understate the impact of postbloom fruit drop disease . However , it is of import to note that complete eradication of PFD may not be feasible , especially during periods of prolong loaded weather condition . Vigilance and proactive management practices are key to extenuate the damage due to this fungous disease .
