With their bright orange tree , glossy fruit , healthy persimmon treesare a sight to behold . Although they endure from few pests and diseases , some cases of various fungal and insect attacks have been report . The most famed of these is persimmon wilt , which bear on trees all along the Southern part of the United States . Additionally , several animal pestilence favour persimmon yield and may cause extra problems .
Persimmon Wilt
Persimmon trees throughout fundamental Tennessee and other parts of the Southeastern United States suffer from persimmon wilt , a disease because of the fungus Cephalosporium diospyri . Symptoms of the disease include wilted and dropped leave . Untended case will contribute to even more serious trouble , like branch death and the eventual destruction of the entire tree . Trees in grove exhibiting this job should be burned , and uninfected trees nearby treated by painting any open cuts or wounding on the control surface .
Leaf Spot
Another disease that infect common persimmon is leaf place . leafage spot , or anthracnose , is due to the fungus colletotrichum . Although not virulent to grownup trees , leaf spot does cause black billet to appear on the surface of folio , and may sometimes affect fruit as well . It can also take to early dropping of leaf – this is most detectable in August , for the North , and September , for the South . Sprays take bake soda or sulfur , or the pesticide Bordeaux intermixture , are commonly used to moderate it .
Crown Gall
lie with to the scientific creation as Agrobacterium tumefaciens , crown gall has sometimes been found on persimmon trees . Trees infect with pennant bitterness develop tumors , or rancour , on their branches and roots , which eventually become heavy and jumpy . The disease collide with young plants the hardest and can often annihilate them , while older flora weaken , but most often subsist the infection . Like persimmon wilt , the contagion spread to open wounds on tree , so deal subsist cuts and bruises on mature trees and being careful to annul extra damage is the good treatment . Young trees that are infected may need to be destroyed .
Fruit Drop
once in a while , persimmons will drop excessive portions of their crop before the yield fully ripen . It ’s called fruit drop and is consider to be physiological – some of the root causes admit overgrown shoot , unequal sunshine , improperly pollinated flush , and excessive watering or fertilizing . Trees suffer from fruit drop may improve after the problem branch are girdle and finally cut off .
Insects and Other Pests
Typically , persimmon tree do not suffer from many problem with pests , but there have been occasional accounts of insects affecting the trees . One case of pest affecting persimmon is the bore bit . Typically these borers consist of either the Agrilus fuscipennis or Sannina uroceriformis varieties . Agrilus fuscipennis strike the barque of mature persimmons , whereas Sannina uroceriformis tends to be most negative to the bow and roots of younger trees . Both kinds of borers weaken the tree by form small tunnel in the leafage , bark and ascendent . Throughout the summer , persimmon tree may also put up defoliation due to caterpillars . Neither caterpillars nor borers do much serious harm ; however , immature plants may be seriously harmed by two pests , webworm ( Seiarctica echo ) and hickory horned devil ( Citheronia regalis ) . Both of these pestis make damage by defoliate young sapling . Additionally , some cases of mealybugs , thrips , mites , emmet and fruit fly have been report .
Animals
Mature fruiting tree may attract a figure of animals to the tree to dine on the fruit . These pests include squirrel , deer , coyote , crumb , opossums and razz . Additionally , gophers that savvy up roots may also be a problem .
